Stuut wants unpaid invoices to become an automated journey instead of a lingering finance problem. The fintech startup has raised $52.5 million in Series B funding to expand its AI-driven platform for accounts receivable, helping companies manage invoice collection and payments from the first reminder through the final match.
The funding announcement arrived on October 7, 2026, with Insight Partners leading the round. Andreessen Horowitz and M12, Microsoft’s venture fund, also participated, bringing Stuut’s total funding to $93 million just ten months after its Series A.
AI Agents Move Accounts Receivable Toward Payment
Stuut is betting that AI agents can carry unpaid invoice work through to payment. That focus reaches beyond sending reminders or organizing finance data: the platform targets the work required to collect invoices, manage payment activity, and connect incoming money to the right records.
That approach addresses a problem Tarek Alaruri, Stuut’s CEO, describes in human terms: “The frustrating thing about this problem is that it’s not just that companies need to get paid more quickly, but that their customers actually want to pay.”
The quote points to the gap Stuut wants to close. A company may have customers ready to pay, yet still spend time tracking invoices, contacting accounts, and matching payments. Stuut’s platform uses AI-driven automation across those steps, turning accounts receivable into a process that can keep moving without a person handling every action.
Stuut reports that 81.7% of outbound collections activity runs without human involvement, while 95% of incoming payments are matched automatically. Together, those figures show how the platform handles both sides of the payment cycle: reaching out when money remains unpaid and recording money once it arrives.
A Growing Platform With Billions in Payment Volume
More than 150 customers use Stuut’s platform, and over $3 billion has moved through it. Those numbers give the company a strong base as it expands its AI agents and brings its accounts receivable automation to more businesses.
Stuut says customers are freeing up to 40% more cash flow through the platform. For finance teams, that outcome connects automation to a result they can measure: less money stalled in unpaid invoices and more cash available after customers complete their payments.
The platform’s reported performance also reveals the two pressures built into accounts receivable. Outbound collections require repeated activity across unpaid invoices, while incoming payments demand accurate matching. By automating both tasks, Stuut is building its case that AI agents can support the full path from an outstanding balance to completed payment.
Fresh Capital Fuels the Next Stage
Insight Partners led Stuut’s $52.5 million Series B, joined by Andreessen Horowitz and M12, Microsoft’s venture fund. The round lifts the company’s total funding to $93 million, arriving ten months after its Series A.
That timing gives the new raise a clear role in Stuut’s story. The company has moved from a funded fintech startup to a platform used by more than 150 customers, with more than $3 billion moving through its systems and AI handling large portions of collections and payment matching.
Now the challenge is scale. Stuut must expand a system that already reports 81.7% of outbound collections activity running without human involvement and 95% of incoming payments matched automatically, while serving more customers and supporting more payment volume.
The opportunity is clear: if AI agents can keep invoice work moving until customers pay, accounts receivable teams may spend less time pushing individual transactions forward and more time managing the broader financial picture. Stuut’s new capital gives that vision room to grow, and its next chapter will test how far automated payment management can reach.
