Selecting lists is straight forward and can be done in minutes. The data is good quality and the Support team responsive. **What do you dislike about Klarity by DemandScience?** It would be great if it would allow users to make selection and show cost where a selection will incur additional costs. If that could be sent to the Admin for approval and the user could then be 'switched on' to to allow the costs and switched off afterwards - that would be a good feature. It would also be great if could pull mobile numbers, email and tech install in one list. **Recommendations to others considering Klarity by DemandScience:** If you need something accurate and easy to use this is your tool. **What problems is Klarity by DemandScience solving and how is that benefiting you?** We have on-demand access to quality data that's easy to navigate and adjust as needed.

You can easily segment the data to find relevant individuals from the correct industries. **What do you dislike about Klarity by DemandScience?** The only two downsides of Leadiro is that you cannot search by city and that you have to remember to select that the email has been accredited. **What problems is Klarity by DemandScience solving and how is that benefiting you?** We are managing to gain a lot of valuable data and have achieved an ROI from our email campaigns of 1250% for the year. ### 15. Better than most mid-level lead poroducts **Rating:** 4.0/5.0 stars **Reviewed by:** Verified User in Education Management | Small-Business (50 or fewer emp.) **Reviewed Date:** December 18, 2020 **What do you like best about Klarity by DemandScience?** It provides data normally not available through services in the same price range. Lead intent, Systems Used, and Direct dials are normaly seen on much pricier programs. With Leadiro, it's no more than the cost of their top tier options. **What do you dislike about Klarity by DemandScience?** There is no ability to quickly identify an already downloaded contact when you run a search under similar criteria. You'll find out when you go to checkout. A small inconvenience, but one, nonetheless. **What problems is Klarity by DemandScience solving and how is that benefiting you?** Direct and Viable contacts are more accurate. As are emails. ### 16. It excellent and have gotten many leads from this software **Rating:** 5.0/5.0 stars **Reviewed by:** Verified User in Computer Software | Small-Business (50 or fewer emp.) **Reviewed Date:** February 04, 2021 **What do you like best about Klarity by DemandScience?** Ease of use and navigation of the software. **What do you dislike about Klarity by DemandScience?** Sometimes the contacts I download have incorrect information.

Of the advantages, I can highlight the speed of the service and the vastness of the contact base. ### 18. An excellent source of emails for lead-gen **Rating:** 4.5/5.0 stars **Reviewed by:** Verified User in Computer Software | Mid-Market (51-1000 emp.) **Reviewed Date:** February 16, 2021 **What do you like best about Klarity by DemandScience?** Leadiro is an excellent source of high quality email addresses with an excellent search facility and good integrations with CRM and marketing automation - highly recommended **What do you dislike about Klarity by DemandScience?** Team options only on highest price subscriptions **What problems is Klarity by DemandScience solving and how is that benefiting you?** High quality lead-gen option ### 19. Leadiro for b2b leads **Rating:** 3.0/5.0 stars **Reviewed by:** Jake S. | Founder, Small-Business (50 or fewer emp.) **Reviewed Date:** December 07, 2020 **What do you like best about Klarity by DemandScience?** Data quantity, lots of leads available and good support team **What do you dislike about Klarity by DemandScience?** UI is pretty old and bland.

Good. Easy. Accurate. **Rating:** 4.5/5.0 stars **Reviewed by:** Verified User in Outsourcing/Offshoring | Mid-Market (51-1000 emp.) **Reviewed Date:** September 26, 2019 **What do you like best about Klarity by DemandScience?** Easy to use. Data seems good. Fair cost. **What do you dislike about Klarity by DemandScience?** After a year of saying Pipedrive integration is "coming soon".....it still have not come. Who knows what they mean by "coming soon." **Recommendations to others considering Klarity by DemandScience:** None. **What problems is Klarity by DemandScience solving and how is that benefiting you?** lead generation. ### 21. The best cost-effective for Technographic Data **Rating:** 5.0/5.0 stars **Reviewed by:** Diógenes D. | Especialista em Growth Marketing, Mid-Market (51-1000 emp.) **Reviewed Date:** April 08, 2020 **What do you like best about Klarity by DemandScience?** I looked for a solution able to do Technographic Data well. All competitors can do it but they are much more expansive than Leadiro. I'm really glad about the platform and its features. The platform should help many companies working in an ABM approach as it can provide really good data such as technographic, market size and industry areas. **What do you dislike about Klarity by DemandScience?** In the Technology Install section, Leadiro allows extracting only the employee´s info making it not able to extract just the companies info. As it charges for each technology install you extract, it would be unable to extract technology install for every employee's info jut to get the companies that are using the solution you are targeting. Luckily the customer success team was able to help me and provided me the companies technology list. **Recommendations to others considering Klarity by DemandScience:** If you are a medium-size company looking for an ABM solution that will provide technographic data, market size and targets info with a cost-effective value, Leadiro is for sure the best option. **What problems is Klarity by DemandScience solving and how is that benefiting you?** The main benefit for me is to extract Technographic Data, Market Segmentation and Prospects Infos that will enrich my ABM list. Running an ABM approach it's essential to know your target market very well, and Leadiro is able to prove the main data for this research. For us its been essential for a TAM and SAM segmentation. With the technographic data, you can refine these TAM and SAM data making it able to create better clusters and tiers, in an ABM approach. In our industry it's essential to know if the companies are using some competitor solution, to build a better awareness fo them. And Leadiro is by far the solution a medium size company in Brazil can afford to get a better ABM approach. ### 22. Fantastic Prospecting Tool **Rating:** 5.0/5.0 stars **Reviewed by:** Greg J. | Small-Business (50 or fewer emp.) **Reviewed Date:** August 25, 2020 **What do you like best about Klarity by DemandScience?** Quality and accuracy of data, the best we have used! We have used several different solutions in the market place and have found the quality and accuracy of data provided by Leadiro to be the best. It has allowed us to create highly targeted marketing lists allowing us to zone in our ideal customer profile. **What do you dislike about Klarity by DemandScience?** The interface could be a bit better and more modern. **What problems is Klarity by DemandScience solving and how is that benefiting you?** Looking at outreach to our target market to promote our solutions and raise brand awareness. ### 23. Quality Leads, Quality Service. **Rating:** 5.0/5.0 stars **Reviewed by:** Verified User in Education Management | Small-Business (50 or fewer emp.) **Reviewed Date:** March 09, 2021 **What do you like best about Klarity by DemandScience?** The leads were fantastic and the service was amazing. Would highly reccomend. **What do you dislike about Klarity by DemandScience?** Nothing, the commercial team were great from start to finish and the product speaks for itself. **What problems is Klarity by DemandScience solving and how is that benefiting you?** Finding new leads for my business. Problem is now resolved. ### 24. best way to get into the big leagues **Rating:** 4.5/5.0 stars **Reviewed by:** Verified User in Marketing and Advertising | Small-Business (50 or fewer emp.) **Reviewed Date:** December 08, 2020 **What do you like best about Klarity by DemandScience?** the vast selection of c-level contacts and large companies **What do you dislike about Klarity by DemandScience?** not enough companies on there needs to have the smaller 1 man bands to get numbers up **What problems is Klarity by DemandScience solving and how is that benefiting you?** targeting large companies and gaining access to the companies correct targets ### 25. I had a great experience with Leadiro! **Rating:** 4.5/5.0 stars **Reviewed by:** Jackson H. | COO and Co-Founder, Small-Business (50 or fewer emp.) **Reviewed Date:** January 23, 2020 **What do you like best about Klarity by DemandScience?** I liked the simplicity of the Leadiro software. Also, it's a fair price for what you're getting. It is easy to filter out the contacts you want to email market or sell to. It takes seconds to get in and get out with what you need. It had all the fields for each contact that we needed to accomplish what we were trying to do. Overall, the software does exactly what you want it to do in my opinion. **What do you dislike about Klarity by DemandScience?** The bounce rate for emails addresses seems to be higher than the benchmark for the industry. That is to be expected with the price they charge though. Something else I didn't love was that I accumulated contact credits faster than I could use them so I didn't love that I had to continually pay each month for a higher number of contacts was higher than I needed. **Recommendations to others considering Klarity by DemandScience:** I would just recommend trying to validate the email addresses on a more frequent basis to decrease bounce rate. **What problems is Klarity by DemandScience solving and how is that benefiting you?** I'm solving the problem of email marketing at scale for a reasonable price. We are a startup so the price was doable for an organization of our size. Through Leadiro we were able to use our email templates to send out to potential prospects found in Leadiro and create leads that we would pass onto our account executives. Leadiro was a crucial piece to the puzzle to create some leads for us. ### 26. Leadiro is the perfect data provider for all of your outbound marketing **Rating:** 4.5/5.0 stars **Reviewed by:** Chloe A. | Business Development Manager, Small-Business (50 or fewer emp.) **Reviewed Date:** October 03, 2019 **What do you like best about Klarity by DemandScience?** Leadiro is a great tool, the data quality, the filtering ability to segment data to the finest details, but my favorite part of Leadiro is the price point, we are using the professional plan which only costs $99 a month, which is a steal in comparison to other data providers, also there are no long term contracts. Its month to month and cancel anytime (not going to be cancelling but its nice to know that their won't be any hassle in getting cancelled). **What do you dislike about Klarity by DemandScience?** The only thing I don't like about Leadiro is related to pricing ironically enough, all payment options are processed in US dollars, we are based in the UK so I'd like to pay in British Pound Sterling. Its a personal preference, but thats really the only qualms we have with the service. **Recommendations to others considering Klarity by DemandScience:** Leadiro is a very cheap and high quality data provider. The support team is always available on hand to help out and answer any questions you might have. The data is top notch, we have not had any issues, it has helped us hit our goals through out 2019 and with our projections for 2020 we'll be hitting them too! **What problems is Klarity by DemandScience solving and how is that benefiting you?** The main problems we are solving with Leadiro is sourcing data. We normally spent an enormous amount of time every month sourcing, building, testing and validating data in-house. Now we have pretty much eliminated that time and are able to focus our efforts on our outbound marketing campaigns, which is great! Especially when you get a commission bonus :D!! ### 27. Leadiro is the Best Data Provider to use in Telemarketing and Email Marketing Campaigns! **Rating:** 4.5/5.0 stars **Reviewed by:** Chloe W. | Content Manager, Small-Business (50 or fewer emp.) **Reviewed Date:** October 03, 2019 **What do you like best about Klarity by DemandScience?** Leadiro is a great data provider, it is easy to use and allows quick and concise segmentation to target the contacts that you would like to specifically target. You select contacts based off of filters like job title, location, etc. and download, its as simple as that. The default export option is via excel files which makes it handy to import the data into your own in-house CRM and Leadiro has integrations with providers like Reply.io, Salesforce and HubSpot which is a great option if we decide in the future to move to one of those provider. **What do you dislike about Klarity by DemandScience?** One of the only gripes I have with Leadiro is the suppression feature, as it is applied during the check-out process rather than in the preview screen. That being said I find with other providers the system at least on my end always feels sluggish when a suppression file is loaded, Leadiro does not suffer from this thankfully. Its a bit of an annoyance, but it works which is the main thing I suppose :D **Recommendations to others considering Klarity by DemandScience:** Leadiro is a great data provider, it takes out all the tedious work of sourcing, building and testing data. Leadiro provides a service where you can segment by job title, level, location, industry, employee size, etc to find the target data you need for your marketing campaigns. Its a very cheap service in comparison to a lot of other providers no long terms, low costs, everything that you need in a data provider! **What problems is Klarity by DemandScience solving and how is that benefiting you?** The main problems we have solved in using Leadiro is sourcing data for our telemarketing and email marketing campaigns. Before using Leadiro, we had a team dedicated to sourcing data for campaigns, the quality was good but the volume was lacking. Leadiro has solved this for us with having access to over 30m contacts in over 90+ countries we are now able to market to countries we had not before! ### 28. Using Leadiro for Marketing Campaigns **Rating:** 4.5/5.0 stars **Reviewed by:** Ashley W. | Marketing Manager, Small-Business (50 or fewer emp.) **Reviewed Date:** October 01, 2019 **What do you like best about Klarity by DemandScience?** Leadiro is a great platform! It allows you to segment by city, state, country, job title, function, industry, employee size, direct dials, basically every category we want to segment by! They have a large pool of contacts available 35m+ across 90 countries. We have been using the platform in our marketing campaigns we have had great success through the data we have received from Leadiro. The team have been great at answering our questions too, they are quick, concise and answer all the questions we have! **What do you dislike about Klarity by DemandScience?** We would like to segment by zip/postal codes at times, unfortunately you are not able to in the platform. You can ask the team to run the searches in the backend they add the search results into your ABM filter. It's a nice option but its a bit slow in comparison to how quick it is to segment by city, state, and country in the platform. **Recommendations to others considering Klarity by DemandScience:** Leadiro is a great platform for use in sourcing contact data for Marketing campaigns, email outreach, telemarketing, etc. We have had great success with Leadiro it also has great integrations with Reply.io, Salesforce and HubSpot. We used these integrations for a little bit it transitioned from Leadiro to the emailing platform seamlessly (We have since changed to an in-house system) it is also very easy to upload the exported excel files into our in-house platform. **What problems is Klarity by DemandScience solving and how is that benefiting you?** We are saving so much time in getting contact data from Leadiro rather than sourcing data in-house this allows to work harder and expand our markets while we create our campaigns. ### 29. Good source of leads **Rating:** 3.5/5.0 stars **Reviewed by:** Verified User in Graphic Design | Small-Business (50 or fewer emp.) **Reviewed Date:** May 15, 2019 **What do you like best about Klarity by DemandScience?** There were a good number of international leads, which most other companies do not have. **What do you dislike about Klarity by DemandScience?** You cannot choose when the leads were last verified. Some of the leads provided were old and no longer in use, or the employee had moved to a different company. **Recommendations to others considering Klarity by DemandScience:** Get the demo and free trial and see if it's right for you. If you're looking for international leads, this is a good source. **What problems is Klarity by DemandScience solving and how is that benefiting you?** We are trying to expand our reach in a new area, Leadiro has helped us gain this exposure with key figures. ### 30. Review of Leadiro **Rating:** 4.5/5.0 stars **Reviewed by:** Verified User in Internet | Mid-Market (51-1000 emp.) **Reviewed Date:** September 26, 2019 **What do you like best about Klarity by DemandScience?** Leadiro is a very easy to use platform, its very intuitive and if you ever have any questions the team is always there to help out with any of our queries! The database has a great coverage of over 90 countries worldwide which is great for our marketing campaigns, we can get data for any campaign and the data quality is top notch! **What do you dislike about Klarity by DemandScience?** I haven't found many issues with Leadiro, they have helpful "help" articles, but sometimes a video would be a quicker solution, that being said its just as easy to drop the support team a message in the bottom right corner they're very helpful and get you back on track with targeting potential leads :) **Recommendations to others considering Klarity by DemandScience:** Leadiro is a great tool and is available at a very good price point in comparison to other data providers, they're plans are month to month rolling plans with cancel any time options so its well worth a punt, if you don't like it you cancel! In my experience though I doubt you will :) **What problems is Klarity by DemandScience solving and how is that benefiting you?** The problems we are solving is data sourcing, before we sourced data internally and by implementing Leadiro we have saved an enormous amount of time ### 31. Leadiro is good for organizations with a broad reach, but maybe not for those with specific targets. **Rating:** 2.5/5.0 stars **Reviewed by:** Verified User in Computer Software | Small-Business (50 or fewer emp.) **Reviewed Date:** December 13, 2019 **What do you like best about Klarity by DemandScience?** The data was pretty accurate - we had a really low bounce rate with leads that we pulled. We were able to generate some new business with the tool as well which was helpful. The pricing is also very good - we were quoted rates over 10x what Leadiro was charging for some similar tools. Perhaps they had better data quality but if you have a lower budget, Leadiro is a good solution to test out having a lead gen tool. **What do you dislike about Klarity by DemandScience?** Seemed to be missing a lot of data for companies we'd expect a tool to have. Large tech companies we were trying to sell into would have 0 contacts which was surprising, while some smaller companies would seemingly have their entire staff in the tool. You also cannot look for specific persons - you have to look by company, title, industry, etc. **Recommendations to others considering Klarity by DemandScience:** If you have a limited budget for a solution like this then Leadiro is a good call. We did a lot of research into several dozen tools and selected Leadiro as a good option - pretty easy to use. Lacks small company information but usually has good information on big orgs. **What problems is Klarity by DemandScience solving and how is that benefiting you?** We were trying to automate some of our list building. We definitely gained value from the leads that we pulled but realized that our target market is a little too specific for a mass outreach tool like this - feel that after about 6 months we were able to extract most of the useful leads that Leadiro had available to us. As such we cancelled. ### 32. My experience has been good, I do like what Leadiro offers for the cost. **Rating:** 4.5/5.0 stars **Reviewed by:** Verified User in Information Technology and Services | Mid-Market (51-1000 emp.) **Reviewed Date:** September 24, 2019 **What do you like best about Klarity by DemandScience?** I really like the verified email address, that is what I like best of the offering. **What do you dislike about Klarity by DemandScience?** I wish there were more phone number contacts in the platform, that would help me with my need, also I would like to be able to do a search for multiple items. Say the city for example. I would like to search for city 1 and city 2 simultaneously, which doesn't look like that is available. I even pinged through chat to ask. **Recommendations to others considering Klarity by DemandScience:** Great platform to consider if you are looking for good email addresses and contact info. If you need full phone number and technology info regularly, this might not give you all you need. But for my needs, we are very happy! **What problems is Klarity by DemandScience solving and how is that benefiting you?** I need good verified contacts that I can email to within specific areas. My company has recently discontinued use of DiscoverOrg as it was getting much too expensive, and Leadiro is a good alternative. ### 33. Leadiro makes my work so much easier **Rating:** 5.0/5.0 stars **Reviewed by:** Verified User in Marketing and Advertising | Small-Business (50 or fewer emp.) **Reviewed Date:** November 04, 2019 **What do you like best about Klarity by DemandScience?** I have tried various vendors in the past and I can definitely say Leadiro is one of the best out there. The email list is 100% genuine, and plus the emails are validated. It is a b2b marketers dream come true. I also find it quite good across a variety of industries from finding clients in construction to retail **What do you dislike about Klarity by DemandScience?** Nothing, There is nothing wrong with the platfrom. My only qualm is pricing has added VaAR. **Recommendations to others considering Klarity by DemandScience:** I have tried various vendors in the past and I can definitely say Leadiro is one of the best out there. The email list is 100% genuine, emails are validated. It is a b2b marketers dream come true. The customer acquisition rates can also be much better from Leadiro contacts than other vendors, I have used previously **What problems is Klarity by DemandScience solving and how is that benefiting you?** For new clients and business, it gives you access to a database. Which can be quite hard for new companies. I have used other list providers before and the open rates and click through rates have been lower than 1% with leadiro I find an open rate higher than 20%. I also find the lists more comprehensive as they provide phone numbers and detailed information on contact. ### 34. Leadiro review **Rating:** 5.0/5.0 stars **Reviewed by:** fabian p. | Executive Director US Operations, Small-Business (50 or fewer emp.) **Reviewed Date:** May 29, 2019 **What do you like best about Klarity by DemandScience?** What I like best is the ease of use. the support given by Leadiro. Flexibility in use and affordability. using Leadiro is very simple and allows for me to focus on other aspects of the business once I have the leads. I like the option to start and stop as required. since se are a small company this flexibility allows us to work the leads without having to pay every month. Customer service is excellent. they re very patient. Best of all it was a soft sell. I did not fee pressured in any way compared to other companies I was comparing prior to getting Leadiro. Great experience working with Leadiro **What do you dislike about Klarity by DemandScience?** What I dislike is the fact that lack of information of revenue/Assets of the companies I am searching. I would like this to be included and be able to sort based on company revenue. this would help for specific enterprise searches. I would also like to be able to search by key word in Job Title. **Recommendations to others considering Klarity by DemandScience:** Always compare but leadiro will be your best affordable source of lead generation. **What problems is Klarity by DemandScience solving and how is that benefiting you?** The problem I solved was getting leads at an affordable price with validated information. I am also able to followup on the leads without having to pay every month. this flexiclity allows my team to work the leads and not have to pay for service I do not need every month. Since any unused downloads stay in the account I may keep using once I start the service again. ### 35. Excellent B2B data provider for email and telemarketing. **Rating:** 5.0/5.0 stars **Reviewed by:** Verified User in Information Technology and Services | Small-Business (50 or fewer emp.) **Reviewed Date:** October 17, 2019 **What do you like best about Klarity by DemandScience?** Leadiro is an easy to use, searchable B2B database, with good, up to date contacts. Compared to other data providers, Leadiro is fantastic value for money with great up to date contacts. **What do you dislike about Klarity by DemandScience?** Searches can be time consuming once you are a few months in; you can't see whether you have already downloaded the chosen contacts or others at the same company until you reach / have passed check out. **Recommendations to others considering Klarity by DemandScience:** The subscription method means you can try for a month and then leave if it's not for you. It's very simple to come and go depending on your campaigns and pick up when you need it. **What problems is Klarity by DemandScience solving and how is that benefiting you?** I was looking for a data provider to provide us with specific target contacts in IT roles, that were up to date and had both email and phone numbers. Leadiro offers a huge list of contacts that you can sort by job title, business sector and region. It is fantastic value for money. ### 36. Leadiro Database and customer service review **Rating:** 5.0/5.0 stars **Reviewed by:** Nadia G. | Senior Solutions Manager, Professional Training & Coaching, Small-Business (50 or fewer emp.) **Reviewed Date:** October 15, 2019 **What do you like best about Klarity by DemandScience?** They are extremely helpful, always on hand to solve any issues and proactive on the customer service side. They are economical also compared with others. **What do you dislike about Klarity by DemandScience?** I would say 70% of leads are valid and 30% not but this is to be expected and not that high based on previous experiences **Recommendations to others considering Klarity by DemandScience:** I would highly recommend, having done a lot of research into others such as uplead, they are definitely the best ive come across. **What problems is Klarity by DemandScience solving and how is that benefiting you?** I am selling more business die to reaching more people. I would and have recommended them to three friends so its safe to assume i am very happy with using them and will continue to use them. ### 37. Leadiro - Brilliant source of Quality Data for Business! **Rating:** 4.5/5.0 stars **Reviewed by:** Verified User in Marketing and Advertising | Mid-Market (51-1000 emp.) **Reviewed Date:** October 09, 2019 **What do you like best about Klarity by DemandScience?** The best thing experience we have had with Leadiro so far is just how user-friendly the User Face is and how helpful the Team is when asking questions via the online chat. We love the conversion rate that we have with using Leadiro Data and because we target various geographies around the globe, the fact that there is data available for all these countries is an added bonus! **What do you dislike about Klarity by DemandScience?** Something I came across this week is that there is not an option to exclude options from the Technology Install - this was a requirement on one of our more complicated campaigns and could possibly be a useful feature to add. We would also like to see some more Direct Dials. **Recommendations to others considering Klarity by DemandScience:** Definately give it a try if you are looking for quality data that can be filtered to meet your requirements in any country in the world! **What problems is Klarity by DemandScience solving and how is that benefiting you?** We are now able to accept more clients because we know that Leadiro will supply our data and this has been a great benefit to business. It is so easy to use that we can have data readily available in minutes. ### 38. Great resource to search for new sales leads **Rating:** 3.5/5.0 stars **Reviewed by:** Verified User in Leisure, Travel & Tourism | Small-Business (50 or fewer emp.) **Reviewed Date:** March 26, 2020 **What do you like best about Klarity by DemandScience?** Access to several potential sales leads all over the world, that can be filtered to fit exactly what you’re looking for. **What do you dislike about Klarity by DemandScience?** New leads/contacts are sometimes hard to come by if you’ve used leadiro a lot recently. **Recommendations to others considering Klarity by DemandScience:** Great place to get new sales leads, if that’s what you’re looking for. **What problems is Klarity by DemandScience solving and how is that benefiting you?** I am working to raise my number of potential sales leads, and leadiro is helping with that. ### 39. Great start, but more to come **Rating:** 3.5/5.0 stars **Reviewed by:** James P. | Head of Business Development, Small-Business (50 or fewer emp.) **Reviewed Date:** July 17, 2019 **What do you like best about Klarity by DemandScience?** The convenience and ease of use. Very straight forward to select contacts via a range of criteria and just as easy to export. Quality of data seems to be pretty high as well, minimal bouncebacks and a promise of returning credits if they do bounceback. **What do you dislike about Klarity by DemandScience?** Bit of a "clunky" UI and UX. it seems illogical to me that once you've selected and exported a contact, there's no annotation next to them in future searches. This means that if you've created a large list recently, then log in to create another similar list within a few weeks after, you can end up reselecting these contacts and you don't find out until you head to the checkout, which can often mean a lot of work down the drain. Also, not particularly keen on not being able to "save" selected contacts to continue later on at a different workstation, not can you share a list with a colleague prior to downloading to verify the contacts are of suitable standard. **What problems is Klarity by DemandScience solving and how is that benefiting you?** Helped immensely in finding a number of good quality contacts for email marketing purposes and growing an internal database. ### 40. Experience has been good overall, some issues with currency of data **Rating:** 3.5/5.0 stars **Reviewed by:** Verified User in Professional Training & Coaching | Small-Business (50 or fewer emp.) **Reviewed Date:** March 25, 2020 **What do you like best about Klarity by DemandScience?** Ability to target the right contact types and job roles **What do you dislike about Klarity by DemandScience?** Lack of coverage on smaller businesses which can be useful for targeting / updating even if not needed for specialist job roles **Recommendations to others considering Klarity by DemandScience:** Check it covers the right segmentation of market by size for you. **What problems is Klarity by DemandScience solving and how is that benefiting you?** Getting detailed and recent contact information - as compared to traditional business marketing base. ### 41. Very cost-effective solution for outbound sales and marketing contacts **Rating:** 4.5/5.0 stars **Reviewed by:** Fred H. | Partner, Small-Business (50 or fewer emp.) **Reviewed Date:** September 26, 2019 **What do you like best about Klarity by DemandScience?** Leadiro provides the most email verified contacts for the lowest monthly payment. **What do you dislike about Klarity by DemandScience?** There are additional charges for narrowing down the markets for identifying potential customers. **Recommendations to others considering Klarity by DemandScience:** I recommend giving Leadiro a try. We have found it to be very useful for in house sales and marketing. **What problems is Klarity by DemandScience solving and how is that benefiting you?** We are using Leadiro for finding potential customers across different business segments and geographies. Leadiro provides access to many more contacts than other services. ### 42. Easy to use and accurate **Rating:** 4.0/5.0 stars **Reviewed by:** Marian H. | Owner, Mid-Market (51-1000 emp.) **Reviewed Date:** October 10, 2019 **What do you like best about Klarity by DemandScience?** The most helpful feature of Leadiro is the high level accuracy of the database. I rarely notice a record that is no longer valid, as somebody that left the job and the address has been deactivated. I also love the link to the person's LinkedIn profile. **What do you dislike about Klarity by DemandScience?** Some countries are less represented. The database is rich in some geographies and less in others. **Recommendations to others considering Klarity by DemandScience:** Match the industries list from Leadiro with the industries list of your CRM in order to get the information right in your CRM. **What problems is Klarity by DemandScience solving and how is that benefiting you?** I build marketing lists that I use for direct marketing campaigns. ### 43. Good for specific use cases **Rating:** 2.5/5.0 stars **Reviewed by:** Ben C. | Sales Manager, Small-Business (50 or fewer emp.) **Reviewed Date:** October 04, 2019 **What do you like best about Klarity by DemandScience?** How you can upload a list of companies and search them all at once and how you can break down your search by the company industries, then job function, then title **What do you dislike about Klarity by DemandScience?** When uploading a list of companies there seems to be a huge gap. I rarely have more than 10% of the companies in searching for found. The till works great if your just looking for any company, but if you're trying to find contacts at a specific company I wouldn't recommend **What problems is Klarity by DemandScience solving and how is that benefiting you?** It has helped with prospecting and building lead lists based on someone's job title and function ### 44. Not much success **Rating:** 3.0/5.0 stars **Reviewed by:** Verified User in Computer Software | Small-Business (50 or fewer emp.) **Reviewed Date:** March 31, 2020 **What do you like best about Klarity by DemandScience?** The ability to find the tech usage, we were looking for outlook users. **What do you dislike about Klarity by DemandScience?** The very high bounce rates, it's not ideal. **Recommendations to others considering Klarity by DemandScience:** Hard to know what the bounce rates will be. They've been high for us. **What problems is Klarity by DemandScience solving and how is that benefiting you?** Acquiring quality leads within specific verticals. ### 45. The experience has been very simple and easy. **Rating:** 4.0/5.0 stars **Reviewed by:** Verified User in Information Technology and Services | Small-Business (50 or fewer emp.) **Reviewed Date:** October 09, 2019 **What do you like best about Klarity by DemandScience?** I like that it is very easy to use and easy to control. I like that it puts it into an excel spreadsheet for you when you download and you don't have to manually put in your data, like other Softwares as that is very time-consuming. I also like that it provides links to organisations employees LinkedIn, making it easier to connect. **What do you dislike about Klarity by DemandScience?** I dislike, that there aren't as many small organizations on the site, especially in the UK and also that the data isn't updated as easily so you have to check if they still work there through other sources. **What problems is Klarity by DemandScience solving and how is that benefiting you?** Leadrio has helped our company to promote our latest project 'The Cloud Leaderhsip' white paper and to find potential new leads for our company to target. ### 46. CCO **Rating:** 4.5/5.0 stars **Reviewed by:** Verified User in Information Technology and Services | Mid-Market (51-1000 emp.) **Reviewed Date:** March 16, 2020 **What do you like best about Klarity by DemandScience?** Technology Install Search Monthly pricing with no term. **What do you dislike about Klarity by DemandScience?** Auto renewal of monthly term.

We added a ton of value to our organization with the information they provided. **What do you dislike about Klarity by DemandScience?** They could use a refresh on their interface. **What problems is Klarity by DemandScience solving and how is that benefiting you?** Business development. We have seen a significant uptick in our sales due to our partnership with Leadiro ### 48. It is alright in some areas, not so good in others and the customer service needs some work **Rating:** 1.5/5.0 stars **Reviewed by:** Verified User in Marketing and Advertising | Small-Business (50 or fewer emp.) **Reviewed Date:** May 03, 2019 **What do you like best about Klarity by DemandScience?** It is a "plug n play" service and so, you need data, off you go - run a search and you can find the data you need. Install data is an additional cost, but it is available. It covers countries very well and is especially useful where seniority is not a big issue. Classification is pretty good for the most part. Their ABM tool is pretty good too. **What do you dislike about Klarity by DemandScience?** LOW SENIORITY CONTACTS and HIGH HARD-BOUNCE RATES. High hard-bounce rates exist mostly in regions like the UAE. Nearly 90% bounce and when I told them that that impacted our "sending reputation" and caused problems with the email campaign provider we use, asking for more information why there was such a massive hard bounce rate, I got a rude response, credited 500 free names and basically ignored. Also, when I previously sent bounce data to them, they complained as it had a couple of addresses that had been sent to them previously. Honestly - this service could be great - but the customer service leaves a bad taste for their overall ability. I question the validity of their validation checking and would be very cautious about sending to their data before running it through unbounce or zero bounce or a service like that. Also, I thought they were a GDPR compliant service but I am not sure that they are. **Recommendations to others considering Klarity by DemandScience:** Better quality checking and improved customer service **What problems is Klarity by DemandScience solving and how is that benefiting you?** Currently, I am not sure whether Leadiro has benefitted my business other than a few leads - I have spent a fair amount with them but will be cancelling my service with them. They need to work on their customer service and quality checking of their data. ### 49. Leadiro is Awesome!!!! **Rating:** 5.0/5.0 stars **Reviewed by:** Verified User in Transportation/Trucking/Railroad | Small-Business (50 or fewer emp.) **Reviewed Date:** September 24, 2019 **What do you like best about Klarity by DemandScience?** I love the fact that there are so many filters to make sure you get the most qualified leads for your business. Plus the price is incredilbe! **What do you dislike about Klarity by DemandScience?** Not much. The only thing I would say can be improved a little is verification. **Recommendations to others considering Klarity by DemandScience:** Leadiro is worth a shot. The price is amazing so you really have nothing to lose. **What problems is Klarity by DemandScience solving and how is that benefiting you?** I am increasing my businesses outreach with leadiro leads. My email marketing has also seen large improvements.q ### 50.
