Stuut Raises $52.5M Series B to Automate Enterprise Receivables

New York-based Stuut has raised $52.5 million in a Series B round led by Insight Partners, bringing its total funding to $93 million. Andreessen Horowitz, M12 (Microsoft's Venture Fund), and Activant also participated.

Stuut automates the order-to-cash cycle for large enterprises — the processes that determine how quickly invoices turn into cash. The round lands as big companies grapple with substantial working capital tied up in receivables.

The software covers:

• Collections, contacting customers via email, SMS and phone
• Access to accounts payable portals
• Cash application and reconciliation of incoming payments
• Disputes and deductions
• Next-action decisions based on previous interactions

"By leveraging AI, we're able to deliver one of the leading solutions with continuous learning loops to improve the customer experience, reduce churn, improve NPS, and deliver better financial performance," said Tarek Alaruri, co-founder and CEO of Stuut.

Who is behind Stuut?

Alaruri grew up in Michigan and studied at Indiana University in Bloomington. He started his career as a freight broker at Total Quality Logistics, where he learned high-volume sales and round-the-clock freight operations.

The job exposed him to a chronic flaw in B2B payments: invoices routinely went overdue over minor issues — a missing purchase order, inaccurate order data — forcing manual intervention by collections teams.

Before founding Stuut, Alaruri worked at IBM Turbonomic and co-founded procurement automation company Fairmarkit, where he served as chief operating officer.

What traction does the company have?

Stuut serves more than 150 customers, including Fortune 50 and Fortune 500 companies. More than $3 billion in invoices has moved through its platform. Named customers include Honeywell, ZoomInfo, PerkinElmer and Verifone.

The company says clients have cut days sales outstanding — a measure of how long it takes to collect payment — by as much as 47%, while freeing as much as 40% more cash flow.

Stuut also claims customers can deploy its system within days while keeping existing approval processes and audit controls, because the platform integrates with existing enterprise resource planning, banking, customer relationship management and payment systems.

Who is the lead investor?

Insight Partners, the New York-based firm backing the round, focuses on software and technology companies and held more than $90 billion in regulatory assets under management as of Dec. 31, 2025. The firm operates internationally, with senior leadership in London, Tel Aviv and the San Francisco Bay Area.

With $52.5 million in fresh capital and backers including Andreessen Horowitz and Microsoft's M12, Stuut now has the resources to push deeper into a receivables market where companies are actively hunting for ways to unlock trapped working capital.
