Middesk
A KYB-as-a-service provider that consolidates Secretary of State filings, EIN matches, watchlists, and BOI signals into a single business verification report.
Middesk is one of the dominant KYB providers for U.S. fintech banks (Mercury, Brex, Relay, Bluevine, Novo all use Middesk in some capacity). Middesk takes a business name + EIN + address and returns a structured report: entity registration status, registered agent, officers, address risk, watchlist hits, beneficial-owner data. Middesk's address-risk signal is a key reason Mercury and others reject CMRA-flagged or registered-agent addresses.
