What our customers say
We've built a complete prototype of our UK offering using just Griffin's sandbox. The modern architecture, simple API and superior documentation has been a breath of fresh air, allowing us to build and iterate fast.

Onboard your customers
Use Verify to simulate KYC/KYB verification checks on UK companies, sole traders and individuals, make onboarding decisions, and view audit trails.
