The platform aggregates data from Secretary of State filings, IRS records, OFAC watchlists, beneficial ownership databases, and adverse media sources to generate a comprehensive business profile that compliance teams use to make onboarding decisions rather than assembling this information manually from disparate government databases. This automation reduces business verification timelines from days of manual research to seconds of API response, addressing the friction that causes commercial customer drop-off during onboarding workflows. Middesk's platform covers the key components of a robust KYB program: entity verification that confirms a business is legally registered and in good standing, TIN matching that validates the business's tax identification against IRS records, beneficial ownership resolution that maps the human individuals behind legal entities for UBO compliance, and watchlist screening against OFAC, FinCEN, and other financial crime databases. The platform provides a compliance workspace where operations teams can review borderline cases, access underlying source documents, and document their decision rationale for regulatory audit purposes — ensuring that the automated data outputs are paired with the human oversight and documentation that regulators expect in a sound KYB program. Middesk is headquartered in San Francisco and was founded by a team with backgrounds in banking and compliance technology, giving it credibility with the compliance and operations leaders at financial institutions who evaluate KYB infrastructure. The platform serves digital banks, payment processors, lending platforms, and fintech companies that are required to comply with BSA/AML business verification requirements and are seeking a modern, API-first solution rather than legacy compliance data vendors. Middesk competes with LexisNexis Business Instinct and Dunn & Bradstreet KYB solutions, differentiating through its automated UBO resolution and its purpose-built design for fintech KYB onboarding workflows. ## Frequently Asked Questions ### What is the difference between KYC and KYB and why does Middesk focus on business verification? KYC (Know Your Customer) verifies individual consumer identities, while KYB (Know Your Business) verifies the legal existence, ownership, and regulatory standing of business entities. Middesk focuses on KYB because business verification involves different data sources — Secretary of State records, IRS TIN matching, UBO resolution — that require specialized infrastructure separate from consumer identity verification. ### What does Middesk do for business verification? Middesk automates business identity verification by pulling data from government registries, Secretary of State filings, IRS databases, and other authoritative sources to verify that a business is legitimately registered, active, and operating as claimed. This enables financial institutions and fintech companies to onboard business customers faster and with greater accuracy. ### How is Middesk priced? Middesk uses a per-verification pricing model based on the number of business verifications or monitoring events processed.
