Sumsub (short for "Sum & Substance") is a global identity verification and compliance platform that helps businesses meet regulatory requirements, prevent fraud, and onboard users quickly and securely. Founded in 2015, the company has become a trusted solution for thousands of organizations operating in finance, crypto, fintech, transportation, gaming, and e-commerce.
Sumsub offers a full-stack verification platform that supports the entire customer journey—from initial onboarding and KYC/AML checks to transaction monitoring and ongoing risk management. Their system supports over 14,000 document types from more than 220 countries and territories, with built-in support for multiple alphabets and scripts including Latin, Cyrillic, Arabic, Chinese, and more. Verification times are impressively fast—onboarding can be completed in as little as 4.5 seconds using non-document flows, or around 20 seconds with standard KYC.
The platform is built around modular, AI-powered tools that include face biometrics, liveness checks, device fingerprinting, fraud detection, and watchlist screening. Businesses can customize their verification logic using a no-code workflow builder that adapts to different user profiles, risk levels, and jurisdictions. A centralized dashboard provides real-time case management and compliance insights.
In addition to individual verification, Sumsub provides KYB (Know Your Business), AML transaction monitoring, ongoing fraud checks, and sanctions screening. Its flexible APIs and SDKs allow for easy integration into mobile and web applications, while ready-made link and QR flows simplify setup for teams with limited technical resources.
