About Sunlight
Sunlight moves B2B payment volume onto card without asking a single supplier to onboard. Our AI agents determine where a bill can be paid by card without a surcharge, then execute that payment through the vendor's own billing or AR portal, returning a confirmed status, receipt, and structured remittance data through a single API. For decades, moving invoice spend onto card meant building a rail or signing suppliers up one at a time. Both are slow, and both leave most of the volume behind. Sunlight takes a different path. Because our agents pay through the portals suppliers already use, the network reaches every supplier without any of them having to join it. AP platforms and bank card programs issue their own cards, send them to us, and capture the interchange on volume that would otherwise have defaulted to ACH or check. We are the AI infrastructure layer that makes that volume reachable.
