Know Your Business (KYB)

Know Your Business (KYB) is the process of verifying that a corporate customer genuinely exists, confirming its legal status, and identifying the individuals who ultimately own or control it before entering a business relationship.
See KYB Verification Back to Glossary

Where KYC verifies people, KYB verifies companies. It confirms registration details against official registries, validates the company's legal standing, identifies directors and authorised signatories, and resolves the Ultimate Beneficial Owners behind the entity — including across multi-layer and cross-border structures.

KYB is essential for banks, fund administrators, payment processors, and any firm onboarding corporate clients. Because corporate structures can mask sanctioned parties or politically exposed persons, KYB feeds directly into sanctions and PEP screening on every owner and controller identified.
