Assessment
Middesk is used by banks, fintechs, lenders, and marketplaces that need to verify business identity before opening accounts or extending credit. Kyle Mack co-founded the company and is its chief executive, and its best use cases are KYB checks, business formation data, and ongoing business monitoring. Prices are quote-based, and its main competitors are Alloy, Persona, and Sumsub.
The July 2022 Series B brought Middesk to about $77M raised. Its site and materials point to fintechs and platforms that onboard small businesses at scale. The product focus is business identity instead of consumer document KYC alone.
It fits a team whose main identity problem is knowing which business is on the other side of an account or loan. It is a weaker fit for a buyer that only needs consumer ID document checks, and for a team that wants every fee on a public page.
Rating by criterion
We score each of the eight criteria out of 100.
Sector criteria
Use it for US business verification. Middesk is built around KYB and business identity data.
Pull formation and registration signals. The platform aggregates business registry and related data for underwriting.
Run checks through APIs. Middesk sells identity-as-a-service for onboarding flows.
Match it to bank and fintech compliance needs. The customer base is built around regulated onboarding.
Vendor criteria
Expect steady product depth in business data. The Series B funded expansion of identity-as-a-service APIs.
Plan an API integration. Onboarding is developer- and sales-led instead of a consumer self-serve tool.
Ask for unit pricing. Public pages do not publish a full per-check rate card.
Bundle monitoring with onboarding checks. Ongoing business monitoring is part of the commercial discussion.
