Know Your Customer and Anti-Money Laundering: the mandatory checks that verify who a user is and screen their activity against sanctions lists and suspicious patterns before and during service.
For anything touching payments, lending, crypto, or gambling these checks are a licence condition. Failing them does not produce a fine so much as a shut-down, and retrofitting them into a live product is painful.
We integrate established verification providers rather than building identity checks ourselves, design onboarding so verification does not kill conversion, and keep audit trails in the form regulators expect.
