FullEnrich is a B2B contact data enrichment platform founded in 2023 and headquartered in San Francisco, California. Co-founded by Benjamin Douablin (CEO) and Paul Seloriot, the company was built around a single idea: no single data provider has complete global coverage, so relying on one is always leaving contacts on the table. FullEnrich’s answer is waterfall enrichment a sequential lookup process that queries 20+ premium data providers (including Apollo, Hunter, Dropcontact, RocketReach, Clearbit, Kaspr, and others) one after another until a verified match is found, all in one call and one subscription.

The platform delivers verified work emails, personal emails, and mobile phone numbers for B2B prospects, with reported find rates of 80%+ globally. Every email is triple-verified and checked for catch-all status to keep bounce rates under 1%. Users pay only when a match is successfully founD one credit per work email, three for personal email, ten for a mobile number with person and company firmographic details included free with every enrichment. Plans include unlimited users at all tiers, and a free trial of 50 leads requires no credit card.

FullEnrich integrates with HubSpot, Salesforce, Clay, Zapier, Make, and n8n, and offers a well-documented REST API for programmatic and bulk enrichment workflows. The platform is GDPR and CCPA compliant and SOC 2 Type II certified. Despite being fully bootstrapped to seven-figure ARR before raising a $2M seed round in February 2025, FullEnrich serves customers including Mastercard, DocuSign, and Brevo, and has earned a 4.8/5 rating on G2.
