What is KYC? (And how is it different from KYB?)
KYC (Know Your Customer) is the regulatory requirement for verifying the identity of customers — typically individuals — before they can use a financial product. KYB (Know Your Business) is the equivalent for verifying the identity, ownership and standing of a company. Both are part of a broader AML (Anti-Money-Laundering) programme that also includes sanctions screening, PEP screening and ongoing monitoring after onboarding.
The KYC market has fragmented into five distinct capability areas. Most mid-market compliance stacks combine two or three of them; banks typically run an enterprise CLM platform that orchestrates specialists.
KYB – Know Your Business
Verifying the legal existence, ownership and standing of a company via official registries, UBO lookup and director data.
KYC – Know Your Customer
Verifying individual identities using document capture, liveness detection, biometric matching and identity data sources.
AML Screening
Screening individuals and entities against sanctions, PEP lists and adverse-media sources to meet anti-money-laundering rules.
Ongoing Monitoring
Continuously watching onboarded customers for changes in ownership, sanctions status or adverse news after day one.
