Prospeo is a B2B data tool for finding people and their verified emails and mobile numbers. It states a database of 280M verified leads and companies, and comes with a LinkedIn extension and an API.
It connects to Clay, Zapier, Outreach and lemlist, with native HubSpot and Salesforce sync on the Growth and Pro plans.
In the stack we suggest to early teams, Apollo finds the company and person and Prospeo verifies the email. It can also source contacts and verify their emails in one pass on its own.
Inside our own engine, where cheaper sources run first, it plays three fallback roles. It is a people search that starts from job titles, used when the earlier sources come back short. It is the last tier of our email-finding waterfall, after Findymail and LeadMagic. And it is the last tier when we look up a person's LinkedIn profile.
Every email it returns is re-verified by a separate verifier before it reaches a campaign, and a scheduled job watches its credit balance so a run never stops halfway.
US dollars, per user. A verified email costs 1 credit and a mobile number 10. Credits do not roll over. Higher volumes are by sales call.
