Sumsub
Fraud & Security🇬🇧 United Kingdom
Three brothers — Andrey Sever and his twins Jacob and Peter — founded Sumsub in 2015 to solve a problem that regulated digital businesses had been solving badly: verifying who a customer is, fast enough that they don't abandon signup, and rigorously enough that a regulator accepts it. What began as a document verification vendor has become an onboarding orchestration platform covering the full compliance lifecycle: identity verification, business verification (KYB) including ownership-structure analysis, AML screening, transaction monitoring, fraud prevention, and case management, delivered through API and SDKs.
The scale claims are aggressive and specific: over 6,500 document types across 220 countries and regions, verification in under a minute on average, and conversion rates published per market — the kind of numbers a company only publishes when conversion is its main selling point against competitors. The methodology follows FATF recommendations and is built against FINMA, FCA, CySEC, MAS and BaFin requirements, which tells you the customer profile: crypto exchanges, trading platforms, fintechs, marketplaces and gaming operators, in that rough order of historical concentration.
Two things distinguish Sumsub in this directory's context. First is what happened in March 2022: following the invasion of Ukraine, the company ceased its Russian operations, chartering flights to relocate team members out of Russia, Ukraine and Belarus — an unusually consequential decision for a company that had built engineering capacity there, and one that reset its corporate footprint toward London and Limassol. Second is where it is going: reusable identity, so a verified user can onboard elsewhere in a few clicks, and — launched January 2026 — AI agent verification, binding automated agents to verified human identities. That second product is a direct answer to the agentic commerce thesis Checkout.com and Adyen have both been building toward. If AI agents start transacting on people's behalf, someone has to establish which human is accountable, and Sumsub is betting that becomes an identity product.
