Stuut, an AI platform that chases unpaid business invoices, raised a $52.5M Series B led by Insight Partners, 10 months after its Series A. The startup began in collections but found that many late payments trace back to earlier mistakes like missing purchase orders, wrong prices, or invoices sent to the wrong person, so it expanded to cover the whole order-to-cash process, from the order through disputes. Its AI handles the follow-up work finance teams used to do by hand, such as contacting customers, logging into payment portals, and matching incoming cash. Stuut says more than 150 companies, including Honeywell and ZoomInfo, now use it, and it plans to put the money toward credit, lending, and moving funds between businesses.
