Middesk
Middesk — Business identity and KYB verification API providing tax ID validation, beneficial ownership, and business data.
Our Verdict
The default US KYB API for fintechs; expect to bolt on a KYC vendor and global registry source.
Pros
- Tax ID validation, UBO and business data in one API
- US-focused coverage with strong registry data
- Clean developer experience, self-serve signup
- Fast turnaround on EIN match and formation docs
Cons
- US-centric, weak outside North America
- Per-verification pricing adds up at scale
- Less depth on sanctions and adverse media
- Not a full IDV stack for individuals
Best for: US fintechs, lenders and B2B platforms verifying business customers with EIN and UBO checks
Not for: Global KYB programs or teams needing consumer KYC and sanctions screening in one platform
