Frequently asked questions
What controls do sponsor banks need?
Visibility into each program's customers, transactions and risk indicators, the ability to set limits and policies, and complete audit trails. We build that oversight into the platform.
Can the platform support card issuing programs?
Yes, integrated with issuing processors, with card programs configured per partner.
What is the difference between BaaS and embedded finance?
Banking-as-a-Service is the infrastructure — licensed banks exposing services through APIs. Embedded finance is the product outcome — a non-financial company offering those services inside its own experience. We build both sides.
Do you support open banking in multiple regions?
We integrate with open banking APIs and aggregators across regions. Coverage depends on the aggregator and the region's standards.
