Stuut closes $67.6M, and the SEC filing does the announcing

Why it matters

The filing discloses a $67.6M offering while leaving all 11 investor identities unknown. Stuut separately has M12 backing and access to Microsoft's procurement and co-selling channels, which could matter as much as the financing if they produce repeatable enterprise sales.

Tarek Alaruri (@TAlaruri), co-founder and CEO of Stuut, signed a Form D showing the New York finance automation business sold $67,597,673 in equity to 11 investors. The offering is fully closed, with $0 remaining, according to the filing accepted by the SEC on September 16th.

The document supplies the number that Stuut left out two weeks earlier. On September 2nd, Stuut announced an investment from M12, Microsoft's venture fund, alongside a Microsoft Marketplace listing and admission to the Microsoft for Startups Pegasus Program. The Form D records the first sale on September 3rd.

The timing puts the M12 announcement and the $67.6 million offering in the same financing window. The filing does not identify the 11 investors or divide the offering among them, so M12's check size and the rest of the syndicate cannot be determined from the public record. Stuut also did not disclose a valuation.

Alaruri returns to enterprise back-office work

The round backs a second-time founder who has spent much of his career turning neglected corporate processes into software products. Alaruri studied chemistry and wrestled at Indiana University, then worked in logistics and enterprise software sales before co-founding Fairmarkit, according to his SIG biography. Fairmarkit automated procurement work around smaller, frequently overlooked purchases; Alaruri served as its COO.

Stuut moved him from the purchasing side of a transaction to the collections side. Alaruri has described accounts receivable as an immediate operating constraint for industrial businesses, where delayed customer payments can hold up hiring, bonuses and expansion. That framing gives Stuut a sharper sales pitch than a typical efficiency product: the software is supposed to bring cash into the bank faster.

Alaruri built Stuut with colleagues including Ben Winter, Stuut's COO and a former Fairmarkit vice president of marketing. The pair had already spent years selling workflow software to enterprise buyers before taking on collections, cash application and related order-to-cash work.

The earlier investor group knew that history. In November 2025, Stuut announced a $29.5 million Series A led by Andreessen Horowitz, with Activant Capital, Khosla Ventures, 1984 Ventures, Page One Ventures, Vesey Ventures, Carya Venture Partners and Valley Ventures participating. Seema Amble of Andreessen Horowitz and Steve Sarracino of Activant joined Stuut's board; both appear as directors in the new filing.

Andreessen Horowitz said it had known Alaruri and Winter for almost two years before investing. Its investment memo focused on their ability to sell into finance teams and on the prospect of moving labor spending into software.

Microsoft offers a route through procurement

Alaruri was explicit about the purpose of the Microsoft relationship. "M12's investment is powerful validation, but the bigger unlock is distribution," he said in Stuut's September 2nd announcement.

That distinction matters in enterprise finance software. Stuut integrates with Microsoft Dynamics 365, SAP, Oracle and NetSuite, but technical compatibility solves only part of an enterprise sale. Marketplace availability can let eligible customers purchase Stuut through existing Microsoft procurement and cloud commitments. The Pegasus program adds Microsoft go-to-market support and potential co-selling access.

Stuut's hiring plans show how Alaruri intends to use those channels. A recent posting for an ISV and marketplace partnerships lead says the role must turn the live Microsoft listing into transacted revenue, finish an AWS Marketplace launch and establish a Google Cloud Marketplace presence. Stuut expects that hire to produce a marketplace transaction in the first month and meaningful Microsoft co-sell traction within two quarters, according to the posting.

Other openings point to simultaneous product expansion. Stuut is recruiting an engineer to build credit products, including trade credit, receivables financing and payment plans, and has been hiring across product, engineering, sales and partner marketing. The $67.6 million gives Alaruri room to build those functions together instead of waiting for the Microsoft channel to mature on its own.

Stuut is selling execution over another dashboard

Stuut markets AI agents that conduct customer outreach through email, SMS and voice, match payments to invoices, process payments and investigate disputes or deductions. Stuut says its software can connect to an existing finance stack in three to four days. Credit remains labeled as coming soon on Stuut's website.

The customer list displayed by Stuut includes Honeywell, ZoomInfo, PerkinElmer, Verifone and NCR Voyix. In an August partnership announcement with Fiserv, Stuut said its agents had collected more than $2 billion in B2B invoices. Stuut also reports an average 40% cash-flow increase, a 47% reduction in days sales outstanding and a 70% reduction in manual tasks. Those performance figures are supplied by Stuut and its customers rather than audited financial disclosures.

Accounts receivable has drawn established vendors such as HighRadius, Billtrust and BlackLine, along with newer AI-focused entrants including Numeric, Maxima and Fazeshift. Numeric raised $51 million in November 2025 as it expanded from close management into cash management and other finance workflows. Capital is flowing toward platforms that promise to execute financial work across systems instead of merely organizing it for employees.

Alaruri's bet is that Stuut can combine that execution layer with the distribution machinery of a major enterprise software vendor. The SEC filing shows how much capital he has assembled for the attempt. The next measure is whether Microsoft Marketplace becomes a repeatable sales channel, rather than another logo on Stuut's partner page.
