Leadiro provides good quality self-service data at a great cost. **Rating:** 4.5/5.0 stars **Reviewed by:** Verified User in Information Technology and Services | Mid-Market (51-1000 emp.) **Reviewed Date:** September 25, 2019 **What do you like best about Klarity by DemandScience?** The interface is clear and user friendly. 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.

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. ### 27. 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 ### 28. 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. ### 29.

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.

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. ### 31. 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. Not as large a database as ZoomInfo. **Recommendations to others considering Klarity by DemandScience:** "Great company to do business, very easy to get set-up and running and very easy tool to use" **What problems is Klarity by DemandScience solving and how is that benefiting you?** Lead Generation.

Well priced but database is not as complete as others **Rating:** 3.0/5.0 stars **Reviewed by:** Victor D. | Chief Revenue Officer, Mid-Market (51-1000 emp.) **Reviewed Date:** December 07, 2018 **What do you like best about Klarity by DemandScience?** There is lots of value here! For the price, it's hard to find any other solution that comes close. The interface is easy to use, very quick, and the ability to search based on tech install (for a small fee) is also a plus. With the validated e-mails, I found that the bounce rate was pretty low. Overall, I'd say that the value of the product is there. **What do you dislike about Klarity by DemandScience?** Unfortunately, the database seems quite a bit smaller than for other products that we've used, like ZoomInfo. ZoomInfo also gave the ability to easily search within companies, while with Leadiro you're pretty much limited to batch searches/downloads of records. **Recommendations to others considering Klarity by DemandScience:** Give it a try as a supplemental data source for your marketing campaigns. **What problems is Klarity by DemandScience solving and how is that benefiting you?** We needed another data source in our marketing stack for cold outreach campaigns in the USA. ROI of Leadiro is fairly easy to prove/achieve since the product is priced well. ### 33.

Could not do without it! **What do you dislike about Klarity by DemandScience?** It is more expensive than I would like. I was also dissappointed when I reached at to the CEO of the company on Linkedin to ask a couple of questions and propose a business opportunity, and he totally ignored it. A simple response would have gone a long way for a customer paying his business money! **Recommendations to others considering Klarity by DemandScience:** Give it a go **What problems is Klarity by DemandScience solving and how is that benefiting you?** Getting the right contacts at the right time ### 37.

Great for data at scale **Rating:** 4.0/5.0 stars **Reviewed by:** Charles S. | Director, Demand Generation and Digital Marketing, Mid-Market (51-1000 emp.) **Reviewed Date:** December 06, 2018 **What do you like best about Klarity by DemandScience?** We get a lot of volume from here and it is super easy to use for the price. I highly recommend this to any company looking to target at scale. **What do you dislike about Klarity by DemandScience?** State filters sometime get messed up and dont work and although I totally expect it for the price, the phone numbers are mostly corporate lines and there are quite a few emails that bounce that I pull out of here. **What problems is Klarity by DemandScience solving and how is that benefiting you?** Demand generation. We get a lot more volume at a cheaper rate then more well known competitors. ### 40. Excellent Product - Short Learning Curve - Great Value **Rating:** 4.0/5.0 stars **Reviewed by:** Michael N. | Managing Director, Mid-Market (51-1000 emp.) **Reviewed Date:** December 06, 2018 **What do you like best about Klarity by DemandScience?** The customer service and the ease of use have been exemplary. **What do you dislike about Klarity by DemandScience?** I wouldn't call it a dislike but some of the search is not as intuitive as I would like... For example, the US state input is only as a two-letter code but a good deal of the data is stored as full state name. I'm not sure if this impacts search results or not. **Recommendations to others considering Klarity by DemandScience:** As affordable as this solution is, I would highly recommend a "live" experience. Give it a try! **What problems is Klarity by DemandScience solving and how is that benefiting you?** Business lead prospecting.

Solid lead database **Rating:** 5.0/5.0 stars **Reviewed by:** Verified User in Marketing and Advertising | Mid-Market (51-1000 emp.) **Reviewed Date:** February 16, 2019 **What do you like best about Klarity by DemandScience?** The simplicity of platform: you pay a fixed monthly fee for a fixed number of exports. They provide refunds on bounced contacts and do not charge you for duplicate exports. **What do you dislike about Klarity by DemandScience?** As always with these services, there is a margin for error when it comes to contact quality. You will see a bounce rate of at least 5%. **What problems is Klarity by DemandScience solving and how is that benefiting you?** We needed contacts for outbound email marketing strategies. The fixed number of monthly contacts allowed us to plan our outreach and understand how we could scale over time. ### 42. Good Scaleable Data Procurement Option **Rating:** 3.0/5.0 stars **Reviewed by:** Verified User in Information Technology and Services | Mid-Market (51-1000 emp.) **Reviewed Date:** December 11, 2018 **What do you like best about Klarity by DemandScience?** The PAYG model of data acquisition is great - there are also good contacts across a wide geographical area. **What do you dislike about Klarity by DemandScience?** The search functionality is less than ideal - It's difficult to really build complex boolean filters (ie. where job title includes "a" and "b" but not "c". **What problems is Klarity by DemandScience solving and how is that benefiting you?** As a campaign-by-campaign data tool, Leadiro works well, the ability to roll over unused contact quota is great for our needs. ### 43. Helpful platform for outbound campaigns **Rating:** 4.0/5.0 stars **Reviewed by:** Verified User in Outsourcing/Offshoring | Mid-Market (51-1000 emp.) **Reviewed Date:** September 10, 2018 **What do you like best about Klarity by DemandScience?** Leadiro solves the hardest part of an outbound campaign - the listbuilding. Great segmentation options so you can get quite narrow audiences to match specific campaigns. Generally low bounce rate and accurate data. **What do you dislike about Klarity by DemandScience?** Filtering wasn't foolproof - can't just bulk enroll contacts in an outbound sequence. Still needs to be manually checked and vetted. **Recommendations to others considering Klarity by DemandScience:** We paired this with Hubspot so we could enroll contacts in an automated outbound email sequence - really efficient way to run a campaign. **What problems is Klarity by DemandScience solving and how is that benefiting you?** Outbound campaigns - lead generation ### 44.

I would have no problem in recommending Leadiro to any company. **What do you dislike about Klarity by DemandScience?** Still hasn't the functionality to integrate with all CRM systems which duplicates work as I have to separately upload to our Dynamics which did take up some time, but not much of a complaint given oh accurate the data is ! **Recommendations to others considering Klarity by DemandScience:** Leadiro gives you the ability to search for companies within a certain geographical area saving you time trawling through Google, LinkedIn etc .

Functions, mainly related to filtering, are absolutely convenient to find and use. I requested a personal demo, which was provided and convinced me to subscribe. The application reflected the promised features. 99% of downloaded contacts were working. **What do you dislike about Klarity by DemandScience?** Distribution of available contracts is really scewed to the right. High number of contacts sometimes not necessarily reflect high number of available companies. **What problems is Klarity by DemandScience solving and how is that benefiting you?** We launched a cold email campaign, telling prospects about our new service. We needed CEO, CTO, IT director / manager contacts to send the mails to. We managed to send out the mass emails, based on Leadiro contact exports. Most of the contacts were working. ### 46.

Not to mention, customer service and response rate is fantastic! **What do you dislike about Klarity by DemandScience?** The quality and quantity of data. We ran every single email through an email verifier. We only received a 40% success rate. Along with that, you can imagine, how quickly we would run through our target audience. **Recommendations to others considering Klarity by DemandScience:** Understand the true amount of contacts that you need. Take Leadiro's quota and divide it by half. **What problems is Klarity by DemandScience solving and how is that benefiting you?** Lead generation. Leadiro provides our company with contacts to expand our reach and penetrate into new geographical markets. ### 50. Quality data and easy to manage! **Rating:** 5.0/5.0 stars **Reviewed by:** Phil D. | Mid-Market (51-1000 emp.) **Reviewed Date:** January 31, 2018 **What do you like best about Klarity by DemandScience?** The Leadiro platform is incredible simple to use and offers great flexibility and filtering. We can take contacts based on location, industry and job title (or a combination of all three) with ease and receive accurate counts in seconds. The huge range of filtering options has meant we can create very focused data sets that receive communications tailored to them. Another feature that is hugely helpful is the Account based marketing lists. These allow for direct targeting of key companies and accounts. Implementation and visibility of these lists is as simple as performing a regular search. Their customer service is always superb. Very easily accessible and alway on hand to assist, be it with a platform query or a more bespoke request. **What do you dislike about Klarity by DemandScience?** A very trivial thing, but when searching for contacts by US State it is required that you know the state code (NY, TX etc). I think a dropdown or tick-box selection of the codes with state name would make US searches slightly easier for people like myself who aren't completely sure on state codes. Other than that i don't dislike anything about Leadiro. **Recommendations to others considering Klarity by DemandScience:** Check out the portal and see how everything works. The Leadiro team are hugely helpful and back up the impressive nature of the portal with their knowledge and professional nature. **What problems is Klarity by DemandScience solving and how is that benefiting you?** We utilise Leadiro's portal and data for a variety of clients, this means we can provide up to date and relevant contacts to our customers and in return they see leads responding to their marketing campaigns with readily available information on each contact ## Klarity by DemandScience Discussions - [Do I need a credit card to sign up?](https://www.g2.com/discussions/sign-up-618830a5-34b6-407c-ad67-f257b99a572e) - 2 comments, 1 upvote - [Can I pay for just one month rather than a monthly subscription?](https://www.g2.com/discussions/payment-plan) - 1 comment, 1 upvote - [Can I upgrade my plan at any time?](https://www.g2.com/discussions/upgrades-94e9e6e3-7bfc-4805-b0e7-ab53cb97df09) - 1 comment, 1 upvote - [Do unused contacts roll over to the next month?](https://www.g2.com/discussions/unused-quota) - 1 comment, 1 upvote - [Am I locked into a 12 month contract?](https://www.g2.com/discussions/contract-5df4e869-4dd0-47a0-afa1-8a05f427a9c2) - 1 comment, 1 upvote - [View Klarity by DemandScience pricing details and edition comparison](https://www.g2.com/products/demandscience-klarity-by-demandscience/reviews?filters%5Bcompany_segment%5D%5B%5D=180§ion=pricing&secure%5Bexpires_at%5D=2026-08-14+14%3A08%3A21+-0500&secure%5Bsession_id%5D=9bdbd7ff-ab91-4935-bdc3-42d3a1b362e9&secure%5Btoken%5D=99e03626deb1467d2126cf4ce496471d87a5c653b0307f83d1feb7e6a08f7c94&format=llm_user) ## Klarity by DemandScience Features **Additional Functionality** - Calendar Sync - CRM - Conversation Intelligence - Lead Qualification - Strategic Planning - Customizable Reports - Visual Analytics - Customer Profiles - Activity Tracking - Alerts/Notifications - Contact Database - Lead Scoring - Data Import/Export - Data Cleansing - Prospecting Tools - Sentiment Analysis - Multi-Channel Data Collection - AI Copilot - Dashboard Creation - Engagement Tracking - Generative AI - Lead Generation - Interaction Tracking - Predictive Analytics - Customizable Templates - Collaboration Tools - For Sales Teams/Organizations **Data Availability** - Contact Data Availability - Company Data Availability - Industry Research Availability - Technographic Data Availability **Lead Generation** - Lead Builder - CRM Integration - Marketing Automation Integration - Data Import & Export Tools **Lead Intelligence** - Lead Enrichment - Lead Quality - Lead Analysis - Browser Extension **Agentic AI - Lead Mining** - Cross-system Integration - Proactive Assistance **Agentic AI - Marketing Account Intelligence** - Autonomous Task Execution - Cross-system Integration - Adaptive Learning - Natural Language Interaction **Data Accuracy** - Contact Data Accuracy - Company Data Accuracy - Technographic Data Accuracy **Lead Intelligence** - Account-level Insights **Agentic AI - Lead Intelligence** - Cross-system Integration **Lead Management** - Segmentation - Account Identification **Agentic AI - Sales Intelligence** - Autonomous Task Execution - Cross-system Integration - Adaptive Learning - Natural Language Interaction - Proactive Assistance - Decision Making - AI/Machine Learning - Third-Party Integrations - Calendar/Reminder System **Platform** - Internationalization - User, Role, and Access Management - Performance and Reliability - Reporting/Dashboards - APIs - Deal Management - Sales Pipeline Management - Lead Management - Contact Management - Workflow Management - Territory Management - Sales Activity Management **Data Availability - Marketing Account Intelligence ** - Technographic Data Availability **Data Accuracy - Marketing Account Intelligence ** - Technographic Data Accuracy **Features** - Lead Builder - Integration to CRM/Marketing Automation - Data Cleaning/Enrichment - Data Segmentation/Filtering - Search - Connections - Reporting - Real-Time Data - Intent Data - Sales Automation - Email Marketing - Real-Time Reporting ## Top Klarity by DemandScience Alternatives - [GTM Workspace - Powered by ZoomInfo](https://www.g2.com/products/gtm-workspace-powered-by-zoominfo/reviews) - 4.5/5.0 (8,875 reviews) - [UpLead](https://www.g2.com/products/uplead/reviews) - 4.7/5.0 (813 reviews) - [Cognism](https://www.g2.com/products/cognism/reviews) - 4.5/5.0 (1,336 reviews)
