Hunter

What Hunter does

Hunter (legally Hunter Web Services, Inc.), incorporated in Delaware and originally founded in Paris in April 2015 by Antoine Finkelstein and François Grante, operates an all-in-one email outreach platform that finds, verifies, and acts on professional contact data at scale. The core technology combines the proprietary VelenPublicWebCrawler with AI-assisted pattern deduction to index 150 million professional email addresses sourced exclusively from public web pages, achieving claimed sub-1% verification bounce rates. The platform exposes this data through a web UI, a RESTful API v2 with SDKs in six languages, native Google Sheets and CRM integrations, 5,000+ Zapier destinations, and an MCP server for LLM integration. Product surface spans Domain Search, Email Finder, Email Verifier, Discover (B2B database), Sequences (cold email campaigns), AI Writing Assistant, Signals (intent data), and TechLookup (technographic targeting), served by browser extensions across Chrome, Firefox, and Edge.

The business model is product-led and freemium-first: a permanent free tier drives top-of-funnel acquisition, with paid plans starting at $34/month (annual billing) consuming usage-based credits that expire after 12 months. A separate Data Platform offers pay-as-you-go API and bulk access, and an affiliate program pays 30% recurring commissions for the first 12 months. The GTM motion is primarily self-serve SMB/PLG, with an enterprise-flavored channel via the 2026 ZoomInfo GTM Studio integration. Customer base is distributed across millions of users (7M+ platform users, 600K+ browser extension users), with enterprise logos including Canva, Vimeo, Semrush, Customer.io, Gartner, and G2 Crowd, and named power users like Lattice, Acquire.com, and SparkToro. The company remains bootstrapped with approximately 25 employees and no external funding.
