Middesk
What ChatGPT, Claude, Gemini & Grok actually say · August 2026
The verdict
Middesk appears in 1 AI-ranked category — best position #1 for kyb apis for onboarding small businesses.
Purpose-built US KYB with direct Secretary of State registration data, IRS TIN matching, watchlist/adverse-media screening, and beneficial-ownership resolution; fast API, strong developer experience, and the de facto choice for fintechs onboarding US SMBs because it verifies thin-file small businesses better than generic identity vendors.
Gemini Unmatched depth and automation for US small business verification, offering direct integrations with all 50 Secretary of State offices and the IRS for automated TIN/EIN matching, good standing checks, and continuous monitoring. Assumes the primary onboarding footprint is US-based SMBs, achieving 70%+ instant approval rates with minimal manual review. Flagged near-tie with Sumsub for top rank, but edges it out for US-centric SMB onboarding efficiency.
Where Middesk falls short, per the models
- Claude US-centric — international coverage is shallow, so cross-border onboarding needs a second provider.
- Gemini Strictly limited to US business entities and lacks native consumer identity verification (KYC), making it unfit for platforms needing international SMB coverage or a single vendor for business and founder verification.
