Over 300,000 accountants have left the profession since 2019. Businesses are handling more customers, more transactions, and more systems than ever. And yet, for all the software built around getting paid, most of the actual work still falls to people chasing down a missing purchase order or logging into an AP portal for the fifth time. Stuut is betting that era is ending. The company has announced a $52.5 million Series B led by Insight Partners, with participation from Andreessen Horowitz and M12, Microsoft’s Venture Fund. That brings total funding to $93 million, just ten months after its Series A closed.
Stuut runs the full order-to-cash process for enterprises, meaning it handles collections, cash application, payments, disputes, and deductions. The claim is that 81.7% of outbound collections activity runs without any human involvement, and 95% of incoming payments are matched automatically. Those numbers are hard to ignore. For context, broken order-to-cash processes can wipe out up to 5% of a company’s revenue. Across the Fortune 500, that’s estimated at roughly $1 trillion per year.
The core problem Stuut is solving is unglamorous but genuinely painful. A missing PO triggers a rejected invoice. That triggers a portal submission. That triggers a short-pay or a deduction. At enterprise scale, this chain repeats across thousands of invoices simultaneously, pulling in teams across sales, finance, and operations. Stuut follows that entire chain, contacts customers via SMS, email, and phone, logs into AP portals, reconciles cash, and takes the next action, all while maintaining context across the full history of each customer relationship.
What makes this harder to dismiss than typical automation pitches is the compounding effect. Every interaction trains the platform on how a specific customer pays, which portals they use, and what typically breaks. That accumulated memory makes Stuut progressively more embedded in how a company operates. It also means switching costs grow over time, which is exactly what investors want to see in an AI infrastructure play.
The platform integrates with existing ERPs, CRMs, bank accounts, and payment systems, and is designed to go live in days rather than months. Every action is auditable, and any behavior change requires explicit approval. That last part matters for enterprise buyers. Finance teams at large companies are not going to hand over collections to a black box, and Stuut’s design acknowledges that.
Customer results back up the pitch. Stuut now has over 150 customers, including Fortune 50 and Fortune 500 companies, and its customer base has grown five times over the past year. More than $3 billion has moved through the platform. Bishop Lifting cut overdue receivables by 35% and freed up $3 million in working capital. ZoomInfo collected $21.2 million and reduced DSO from 51 to 40 days. Honeywell is running Stuut on top of legacy SAP and expanding into quote-to-cash.
Stuut is also building out a partner ecosystem that includes Fiserv, EY, Altamont, and HIG. These partnerships are not just for distribution. They position Stuut inside the working capital conversations that enterprises are already having with their advisors and financial services providers.
The competitive picture is worth naming. Companies like HighRadius, Billtrust, and Versapay have been in this space for years. What Stuut is arguing, and what its early metrics seem to support, is that those platforms still require humans to manage the work rather than removing that requirement entirely. The difference between organizing work and executing it is where Stuut is staking its claim. The company is growing over 90% quarter over quarter. If that holds, this round won’t be the last.
