Stuut raises $52.5 million Series B led by Insight

Stuut has raised a $52.5 million Series B led by Insight Partners, the New York company said on October 7, 2026, with Andreessen Horowitz, M12, Microsoft's Venture Fund, and Activant also taking part. On March 10, 2026, Stuut announced a $29.5 million Series A led by Andreessen Horowitz and told buyers to expect 37% faster days sales outstanding (DSO), 40% more revenue collected and a 70% cut in manual tasks. By a September 2 post, the same firm was publishing a 47% DSO reduction and a 40% increase in cash flow.

The Series B funds that shift. Stuut is now selling an AI coworker that posts cash into the enterprise resource planning (ERP) system, not a screen that tells a clerk whom to call. A company that rewrites its performance claim between March and September, while moving the product from follow-up into the ledger, is selling execution rather than a dashboard.

Tarek Alaruri, chief executive of Stuut, wrote that the company raised "because demand for Stuut has grown far beyond where we started." More than 150 companies now use Stuut, and more than $3 billion has moved through the platform, the firm said, with DSO down 47% and as much as 40% more cash flow. Those figures are Stuut's, not an auditor's. Stuut calls the gap since the Series A 10 months. The posts are dated March 10 and October 7, with no separate close date.

What the capital is for

Stuut began in collections, Alaruri wrote, because an overdue balance was usually the last sign of an earlier break. The October 7 post puts receivables worldwide at $16 trillion, and says a broken order-to-cash process can cost a company 5% of revenue, close to $1 trillion a year across the Fortune 500. One system, Stuut says, now covers order management, credit, collections, payments, cash application, disputes and deductions.

Insight Partners is leading because it thinks that execution layer is the product. Julian Marcu, vice president at Insight Partners, wrote that Stuut matches payments, reads remittances and posts approved entries back into SAP, Oracle, NetSuite, Microsoft Dynamics and QuickBooks, in days rather than six to 18 months. In comments reported by SiliconANGLE, he said: "A single invoice error can trigger weeks of follow-up across teams and systems and at scale that adds up to real revenue left on the table."

Customers are already pulling Stuut past collections. ZoomInfo has expanded it into disputes, Honeywell runs it on legacy SAP and is moving into quote-to-cash, and Bishop Lifting uses it across 45 branches, the company said. Jeff Martini, chief financial officer of Bishop Lifting, said the firm runs Microsoft Dynamics on-premise and that Stuut "was still up and collecting within days, if not hours," with open receivables down by millions of dollars in the first 90 days. SiliconANGLE, citing Stuut, added a ZoomInfo figure the October post does not repeat: DSO from 51 days to 40.

Rivals and what follows

HighRadius, Billtrust and Tesorio do not appear as commenters in the company post or the Insight note. The new money is going to younger agents doing the same job. Monk's $25 million raise for accounts receivable, and Amex Ventures' backing of Fazeshift, are the nearer comparisons. The pattern looks like the embedded-finance bet Cross River has been funding: the seat that matters is inside a system the customer will not rip out.

M12 was already in before this announcement. The September 2 post paired the investment with a Microsoft Marketplace listing and the Microsoft for Startups Pegasus programme. Cheryl Cheng, managing partner at M12, said: "For 40 years, software helped people work faster. Now, for the first time, AI can actually do the work." Alaruri's line in that post is what this round has to pay for: "M12's investment is powerful validation, but the bigger unlock is distribution." The October round names Activant again.

FinTech Global matches the company on the lead investor, Activant, throughput above $3 billion, and the claim that every enterprise proof of concept became a paying customer. SiliconANGLE puts total funding at $93 million. The two rounds Stuut has spelled out sum to $82 million, and the October posts do not itemise the rest or state a valuation. Stuut says every action is auditable. That line is tested the first time an entry is wrong.

Alaruri wrote that the round lets Stuut go deeper into "credit, lending and the movement of funds." Credit is not collections. Predicting payment timing, which Marcu wrote that Stuut already does, is a short step from deciding who may buy on account. Stuut has not published the sample behind the 47% DSO figure. The next test is whether a days-not-months install survives the controls he says the product respects.
