Argorant
Argorant is a B2B contact database built for revenue teams that are tired of bounced emails and enterprise pricing. Search 614 million contacts across 184 countries by plain-English industry — type ‘fintech’ or ‘dental practices’ and get the right companies instantly. Every email is verified with a live SMTP probe at export, with catch-all servers flagged separately, so you download deliverable addresses instead of pattern-matched guesses. Argorant is fully self-serve: free trial with no credit card, paid plans from under $100 per month, monthly billing available, cancel in one click. It also ships a REST API, webhooks, and an MCP server so AI agents like Claude and GPT can search, verify and export leads directly.
