Middesk

Overview

Middesk, founded in 2018, is a leading business identity (KYB) provider that verifies company existence, ownership, and risk for US businesses onboarding other businesses. It fills the KYB side of verification that consumer-focused IDV vendors do not cover, and is popular with fintech, lenders, and payments companies. See all identity verification vendors for alternatives.

What it is good at

US business data is the strength: registration and good-standing checks, beneficial-ownership insight, TIN matching, and watchlist screening, delivered through a clean, well-documented API. The developer experience is strong for an enterprise data product, and the focus on KYB means the workflows are purpose-built rather than bolted on. Beyond core verification it surfaces structured business attributes, officers, and industry classification, which lenders and payments teams use to enrich underwriting and risk decisions, not just pass or fail an applicant.

Where it falls short

Middesk does KYB, not consumer identity verification, so you will pair it with a separate IDV vendor for individuals. Coverage is centered on US businesses, with limited depth for international entities, and pricing is quote-based rather than self-serve. As a focused KYB product it does not handle AML transaction monitoring or consumer document checks, so a full onboarding stack still needs additional vendors layered alongside it.

Best for, and who should look elsewhere

Choose Middesk when you verify US businesses and need reliable KYB data and ownership insight. For consumer document checks pair it with Onfido or Veriff; for global multi-country person and business data consider Trulioo.

Bottom line

The go-to KYB choice for US business onboarding, best paired with a consumer IDV provider.
