Stuut Raises $52.5M to Deploy AI Agents for Enterprise Collections

Stuut, a New York-based fintech startup, has raised $52.5 million in Series B funding to help enterprises automate the complex process of collecting unpaid invoices and managing the broader order-to-cash cycle.

The round was led by Insight Partners, with participation from Andreessen Horowitz and M12, Microsoft's venture fund. The new financing comes just 10 months after Stuut's $29.5 million Series A and brings the company's stated total funding to $93 million.

Stuut plans to use the capital to respond to growing customer demand and expand further into financial infrastructure, including credit, lending, and the movement of funds.

Turning Accounts Receivable Into an AI Workflow

For large companies, collecting an unpaid invoice is rarely as simple as sending a reminder.

A missing purchase order can result in a rejected invoice. That can lead to portal submissions, short payments, deductions, disputes, and multiple rounds of manual follow-up between finance teams and customers.

Stuut is building AI agents to handle these processes as one connected workflow.

The company's platform brings together order management, credit, collections, cash application, payments, disputes, and deductions.

Its agents can contact customers through email, SMS, and phone, access accounts payable portals, reconcile incoming payments, and determine what should happen next while retaining the context of previous interactions.

Stuut says 81.7% of its outbound collections activity now runs without human involvement, while 95% of incoming payments are matched automatically.

The $16 Trillion Receivables Problem

Stuut estimates that businesses globally have around $16 trillion tied up in unpaid receivables.

The problem is becoming more challenging as finance teams face increasing workloads and staffing pressure. Stuut says more than 300,000 accountants have left the profession since 2019.

Accounts receivable financing is already a significant financial market. The Business Research Company estimates the global market was worth $164.06 billion in 2025 and could reach $277.68 billion by 2030.

Stuut is taking a different approach from lending against unpaid invoices. Its software attempts to help companies actually collect those invoices faster.

The company says its customers have reduced days sales outstanding by 47%, although that figure is self-reported.

Connecting the Entire Order-to-Cash Process

Stuut was founded in 2024 by Tarek Alaruri, Ben Winter, and Miraj Mohsin.

Alaruri serves as CEO and previously co-founded procurement software company Fairmarkit, where he was chief operating officer.

Stuut connects with enterprise resource planning systems, bank accounts, customer relationship management software, and payment systems.

The company says customers can go live within days.

Its system also maintains an audit trail for actions taken by its AI agents. Finance teams can review what the platform did and why, while changes in agent behaviour require approval.

This is particularly important for enterprise finance teams, where an automated decision can have direct consequences for revenue and customer relationships.

A Competitive Market

Stuut is entering a growing category of software companies using AI to automate accounts receivable and finance operations.

Competitors include Lunos, Cleavr, and Fazeshift.

Lunos raised a $5 million pre-seed round in 2025, while Fazeshift raised $17 million in Series A funding in May 2026.

Cleavr, which focuses on AI-powered invoice collection, has also raised funding to automate payment follow-ups.

Stuut is attempting to differentiate itself by expanding beyond collections into the entire order-to-cash process.

That includes the steps between a sale and the moment the money actually reaches a company's bank account.

Strong Investor Support

Insight Partners led Stuut's latest round after previously backing Xelix, another company focused on AI-powered finance automation.

Andreessen Horowitz led Stuut's Series A and is participating again in the Series B.

M12, Microsoft's venture fund, has also backed the company. Stuut previously announced its listing on Microsoft Marketplace and acceptance into the Microsoft for Startups Pegasus Program.

Earlier investors include Khosla Ventures, Activant Capital, 1984 Ventures, and Page One Ventures.

The latest round gives Stuut significant backing as it moves deeper into enterprise financial infrastructure.

What's Next for Stuut?

Stuut wants to go beyond simply chasing unpaid invoices.

The company says it plans to expand into areas including credit, lending, and the movement of funds, potentially giving its AI agents responsibility for more decisions throughout the financial lifecycle of a transaction.

That ambition also raises an important question for enterprise finance teams.

Collecting an overdue invoice is one thing. Allowing an AI system to decide whether a short payment is valid, how a dispute should be handled, or what action should happen next is a much bigger step.

Stuut's rapid customer growth suggests companies are increasingly willing to automate parts of this process.

The next test will be whether those AI-driven decisions can deliver measurable results that stand up beyond the company's own reported numbers.
