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. Review collected by and hosted on G2.com. 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. Review collected by and hosted on G2.com. 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. Review collected by and hosted on G2.com. 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. Review collected by and hosted on G2.com.

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. Review collected by and hosted on G2.com. Recommendations to others considering Klarity by DemandScience: Great platform to consider if you are looking for good email addresses and contact info.

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.

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.

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 Review collected by and hosted on G2.com. 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.

Head of Business Development Small-Business (50 or fewer emp.) 7/17/2019 Business partner of the seller or seller's competitor, not included in G2 scores. "Great start, but more to come" 3.5/5 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. Review collected by and hosted on G2.com. 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. Review collected by and hosted on G2.com. What problems is Klarity by DemandScience solving and how is that benefiting you?
