AI agents

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. Sunlig

Salus

match 71

Your agent processed a refund without looking up the order ID, costing you thousands. You only found out three hours later from a support ticket. Evals, output scoring, and observability can reduce the likelihood of mistakes like these occurring - but there's no solution that inspects and prevents an action as it’s about to execute. Salus does that. We’ve built an API that wraps around your agent and checks its actions at run time, blocking incorrect ones and providing immediate feedback to guid
