Stuut raises $52.5 million Series B led by Insight. Stuut raised a $52.5 million Series B led by Insight Partners. Between March and September, its published DSO claim moved from 37% faster to a 47% cut. 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. Reporting by Rick Steves.

AI fintech Stuut raises $52.5M to expand order-to-cash automation. New York-based fintech Stuut has raised $52.5 million in Series B funding to expand its AI-driven order-to-cash platform, targeting one of the least visible but financially important problems inside large companies. The round is led by Insight Partners, with participation from Andreessen Horowitz (a16z), M12, Microsoft's venture fund, and Activant Capital, according to Stuut's October 7 announcement. The company says the new financing takes its total funding to $93 million. Stuut says more than 150 companies now use its software, including Fortune 50 and Fortune 500 businesses, and that more than $3 billion in payments has moved through the platform. It also reports that customers are freeing up to 40% more cash flow and reducing days sales outstanding, or DSO, by 47%. Those performance figures come from Stuut and should not be treated as independently audited industry benchmarks. "Most businesses don't have the bandwidth to segment their base or give customers the level of service they deserve," said Tarek Alaruri, CEO of Stuut. "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." About Stuut, and How Stuut's AI agents work. Stuut was founded in New York in 2024. Tarek Alaruri and Ben Winter founded the company; earlier financing coverage also identified Miraj Mohsin as a co-founder, while Stuut's current leadership page identifies Alaruri and Winter as its founders. Alaruri previously co-founded the procurement technology company Fairmarkit. Stuut's origin story is closely tied to the observation that many overdue invoices are not simply cases of customers refusing to pay. A missing purchase-order number, incorrect billing information, shipment problem or a payment routed through the wrong portal can create a chain of administrative work that delays collection. Stuut's platform connects to an enterprise's existing ERP, banking, CRM and payment systems. The company lists integrations with major enterprise platforms including SAP, Oracle, NetSuite and Microsoft Dynamics 365. Once connected, the software can work across several stages of the O2C process. Collections: The collections agent contacts customers about unpaid invoices. Stuut says it can identify billing contacts and communicate through email, SMS and voice, including outreach before an invoice becomes overdue. Cash application: Cash application is the process of matching money received in a company's bank account to the appropriate open invoices in its accounting system. This can become complicated when the payment does not contain clean remittance information, when a customer pays multiple invoices together or when a payment spans multiple legal entities or currencies. Stuut says its system automatically matches incoming payments and reports a 95% automated cash-application match rate. Its product documentation says the system can process different payment formats and match transactions across entities, currencies and organizational hierarchies. Disputes and deductions: This is where the O2C problem becomes more complicated. A customer may deliberately withhold part of a payment because a shipment was incomplete, goods were damaged, a promotional allowance applies or freight charges are being disputed. Stuut says its system investigates disputes and deductions, checks supporting information and can categorize and resolve routine cases. Its product documentation describes workflows involving proof of delivery, return records, contracts and customer-provided reason codes. The company says its system can create a credit memo for qualifying deductions and leave negotiations and more difficult judgement calls with finance staff. That division between automation and judgement is important because financial operations have consequences beyond efficiency. A wrong deduction decision can become a customer dispute or an accounting problem. Payments: Stuut also provides payment functionality, including click-to-pay options and processing of incoming payments, according to its product materials. That relationship is important because Stuut's long-term strategy is moving closer to the actual movement of money rather than stopping at receivables software. Order management: Stuut is moving further upstream into order management. That is a much larger part of the enterprise workflow. Stuut lists credit as a coming capability. Stuut's funding history is unusually compressed. In November 2024, a Securities and Exchange Commission filing showed an initial $5.91 million private funding round. Startup databases and employment listings also report the company's early seed funding at around $6 million to $7 million. That early capital came as Stuut was building its first accounts-receivable automation product. In November 2025, the company announced a $29.5 million Series A led by Andreessen Horowitz, with participation from Activant Capital, Khosla Ventures, 1984.vc, Page One Ventures, Vesey Ventures, Carya Venture Partners and Valley Ventures. a16z's Seema Amble and Activant's Steve Sarracino joined the board as part of that financing. The Series A supported expansion of Stuut's autonomous accounts-receivable platform across collections, payments, cash application, deductions, credits and disputes. The move from roughly $6 million in early capital to $29.5 million Series A and then today's announced $52.5 million Series B is a rapid progression for a company founded only in 2024. Stuut's announcement says the company has raised $52.5 million in Series B funding and that total funding is now $93 million. However, a September 16 SEC Form D filing from Stuut reports a $67,597,673 Rule 506(b) equity offering to 11 investors, with the first sale dated September 3, 2026. Several private-company databases classify that $67.6 million filing as Stuut's Series B. CB Insights, for example, currently lists a $67.59 million Series B dated September 15 and total funding of about $103 million. Stuut says the funding will be used to respond to customer demand, deepen coverage of the order-to-cash process and expand into credit, lending and money movement. Its existing customer base includes large organizations such as Honeywell, ZoomInfo, Verifone and PerkinElmer, as well as midmarket businesses. The company is also building partnerships with financial and professional-services companies, including Fiserv and EY, while its Microsoft relationship gives it another enterprise distribution channel.
