Finance-agent startup Stuut raises $52.5M Series B to automate collections, cash application, payments and disputes

What changed

Stuut announced a $52.5 million Series B on October 7 led by Insight Partners, with Andreessen Horowitz and Microsoft's M12 participating, bringing total funding to $93 million. Its AI agents run order-to-cash workflows across accounting, banking, sales and payment systems, including collections, cash application, payments, disputes and deductions. The company says it serves more than 150 customers and has processed over $3 billion through the platform. Stuut also reports up to 40% more cash flow freed and a 47% reduction in days sales outstanding; those performance figures are company-reported rather than independently audited.
