AI underwriting trained on real performance, an API your developers will want to use, and a data advantage that compounds with every funded deal.
Models trained on over $1B of funded deal performance. Real-time credit decisions that sharpen every month as the system learns from every customer in the network.
REST API, webhooks, SDKs, hosted UI components, and a partner dashboard. Documentation your engineering team will actually want to read.
