Contact database
Search business contacts by title, company, industry, and location.
Build, save, and share B2B contact lists for prospecting with enriched email data.
Klarity is a B2B sales intelligence tool from DemandScience, originally known as Leadiro, for building, saving, and sharing contact lists for outreach. Users filter a database of business contacts by company, title, industry, and location, then export verified emails to their CRM. It includes data enrichment, account-based list building, and bounce credits for undeliverable emails. Sales development reps, marketers, and founders use Klarity to find prospects and prioritize accounts.
Charlie T.
Founder & CEO
“Liked that it is very easy to use and keeps its core features simple. Found that the contact pool leans toward smaller companies.”
Dean M.
Marketing Analyst
“Liked the ease of use, list uploads, bounce credits, and search. Found data quality and volume not worth the cost, with only 40 percent of emails usable after cleaning.”
Michael P.
Sales Operations Manager
“Liked the value and how it helped rebuild a prospect database after GDPR. Found no major problems but wanted previously exported contacts hidden from new searches.”
Justin M. N.
Chief Revenue Officer
“Liked the prompt support, ease of use, and affordable leads with a low cost per lead. Found the interface somewhat dated.”
Mohammad A.
President & Founder
“Liked the easy interface and quick, useful search results. Found Boolean search needs work and combining industries narrowed results too much.”
Ariel S.
Sales
“Liked the look of the interface. Found the leads irrelevant, many email accounts already deleted, and the outreach response rate at zero.”
Mark H.
Managing Director
“Liked how easy it is to choose search criteria and the clean interface. Found that smaller markets need more contact volume and better quality.”
Conor D.
Sales Development Representative
“Liked the easy interface and useful persona data for targeting. Found duplicate personas, Salesforce conversion problems, a dated look, and screens that froze until refreshed.”
Cathryne R.
Owner
“Liked that it is easy to use and that data is simple to sort. Found data quality sometimes lacking and recovering credits took too much effort.”
George C.
Business Development Manager
“Liked having monthly access to a subscription contact database for prospecting. Found the data quality weaker than some competing data providers.”
Oday B.
Account Development
“Liked the good price and straightforward search tools. Found there were not enough contacts and no way to look up an individual by name.”
Donald J.
B2B Dev. Team
“Liked the ease of use, subscription model, and email data. Found it needs more leads, a validation check for inaccurate records, and direct phone numbers.”
Steve B.
Co-founder
“Liked the easy platform and decent database. Found accuracy inconsistent, title filtering in need of improvement, and the third-party data source a concern.”
Alex F.
CEO
“Liked the ease of use, helpful support, and good value for money. Found the search function hard to understand at first.”
