Frequently Asked Questions
Get clear answers about our enterprise-grade KYC onboarding solution, built to meet compliance and scale with your user base.
A standard deployment for a fully functional, white-labeled KYC bridge takes 4-6 weeks from kickoff to production. This includes integration with your existing user database, custom rule engine configuration, and deployment to your staging/production environments. Complex requirements like multi-jurisdictional compliance or custom identity verification providers may extend this timeline, which we scope and quote for upfront.
