Stuut Raises $52.5M Series B to Automate Order-to-Cash
Stuut, a New York startup that uses AI agents to follow an unpaid invoice through to payment, announced a $52.5 million Series B on Oct 7. The round was led by Insight Partners, with Andreessen Horowitz and M12 (Microsoft's venture fund) participating, bringing total funding to $93 million, ten months after its Series A.

What happened
Order-to-cash covers everything between accepting a customer order and recording the payment. Stuut's agents handle collections, payments, cash application, disputes and deductions — contacting customers via SMS, email and phone, working inside AP portals, reconciling incoming cash, and taking the next step while retaining the account's full context.
Per the company, more than 150 customers use the platform and over $3 billion has moved through it. It reports that 81.7% of outbound collections activity runs without human involvement and 95% of incoming payments are matched automatically; customers are said to free up to 40% more cash flow and cut days sales outstanding (DSO) by 47%. These are company-reported figures, per the announcement.
Named customers include Bishop Lifting (35% cut in overdue receivables across 45 branches), Honeywell and ZoomInfo ($21.2M collected through Stuut, per the release). The new funding will support expansion into credit, lending and fund movement, and the company says the business is growing more than 90% quarter over quarter — though the release doesn't specify which metric that figure measures.
