Stuut, an AI platform that automates order-to-cash operations for large enterprises, has raised US$52.5 million in Series B funding led by Insight Partners. Andreessen Horowitz, M12 (Microsoft's Venture Fund), and Activant also participated in the round, which comes ten months after the company's Series A. The new investment brings Stuut's total funding to US$93 million as it targets a global pool of US$16 trillion in unpaid receivables.
The Problem
Most customers intend to pay, but missing purchase orders, bad order data, or misdirected invoices trigger weeks of emails, portal work, and internal chasing. At enterprise scale, getting paid becomes millions of small investigations that consume thousands of hours. Stuut estimates that broken order-to-cash processes can wipe out as much as 5% of company revenue, or up to US$1 trillion a year across the Fortune 500 alone.
How It Works
Stuut follows the entire chain of an invoice issue across thousands of invoices at once, reaching customers through SMS, email, and calls while logging into accounts payable portals and reconciling cash. The platform builds a living memory of each customer, including payment habits, portal preferences, and recurring issues. It integrates with existing ERPs, bank accounts, CRMs, and payment systems, and it can go live in days.
Automation at Scale
Stuut reports that 81.7% of outbound collections activity runs without human involvement, while 95% of incoming payments are matched automatically. The platform now extends into credit and order management, catching issues upstream before they become payment problems. Enterprises can keep their existing processes and controls, with every action auditable and any behavior change requiring approval.
Enterprise Partnerships
Stuut is partnering with working capital and financial services firms such as Fiserv, EY, Altamont, and HIG to help enterprises buy, deploy, and scale the platform. Fiserv Senior Vice President Jackson McIntosh noted rising demand for solutions that combine AI, automation, and payments expertise. EY-Parthenon Partner Shawn Ryan added that autonomous execution removes capacity ceilings while holding to the controls global enterprises require.
Customer Traction
More than 150 customers now use Stuut, including Fortune 50 and Fortune 500 companies, and the customer base has grown fivefold since last year. More than US$3 billion has moved through the platform. Leading customers already include Verifone, Bishop Lifting, Honeywell, and ZoomInfo as enterprises expand Stuut across the order-to-cash lifecycle.
Customer Results
Bishop Lifting rolled Stuut across 45 branches for collections, disputes, and cash application, cutting overdue receivables by 35%, unlocking US$3 million in working capital, and increasing accounts managed per employee by 50%. Honeywell runs Stuut on top of legacy SAP to reach the long tail of customer accounts and is expanding into quote-to-cash. ZoomInfo has collected US$21.2 million and reduced time to first touch by more than 90%.
Why It Matters
Finance teams are handling more customers, transactions, and systems while more than 300,000 accountants have left the profession since 2019. US businesses carry US$7.2 trillion in trade receivables, and every additional day of DSO leaves roughly US$150 billion tied up. Because software can now execute work rather than simply organize it, order-to-cash is becoming one of the highest-value deployments of AI.
Looking Ahead
With quarterly growth above 90%, Stuut will use the new funding to meet customer demand and expand deeper into the financial infrastructure around each transaction, including credit, lending, and the movement of funds. The company aims to carry every transaction from the decision to sell through documents, payments, and final cash settlement. Its broader goal is to make selling easier for the world's largest enterprises.
Stuut's Series B round signals growing investor conviction in AI systems that execute financial operations rather than simply support them. The company's rapid customer growth and expanding product scope position it to capture more of the US$16 trillion tied up in unpaid receivables. As enterprise finance teams face capacity constraints, autonomous order-to-cash platforms may become essential tools for improving working capital.
