About Stuut
Stuut is a New York company that makes AI software for accounts receivable, the work of turning invoices into collected cash. Instead of flagging overdue accounts for a finance team to chase, its system does the follow-up itself. It emails, texts and calls customers, logs into their payment portals, matches incoming payments to the right invoices and investigates disputed or short-paid bills.
The company sells to corporate finance teams, including Fortune 500 enterprises, and its software runs on top of the ERP systems they already use rather than replacing them. Customers named on its website include Honeywell, ZoomInfo, Verifone, PerkinElmer and Bishop Lifting. It is led by co-founders Tarek Alaruri, the CEO, and Ben Winter, the COO. The two worked together at Fairmarkit, which Alaruri co-founded and where Winter ran marketing.

Why Investors Backed Stuut
Stuut's September 2026 offering drew $67.6 million from 11 investors, an average of about $6.1 million each. Checks that size usually come from venture funds rather than individual angels. An earlier round in November 2024 raised $5.9 million from 12 investors. Stuut's 2026 round is a $52.5 million Series B led by Insight Partners. The $67.6 million figure counts all consideration received for the shares sold, so it can differ from an announced round size. Here is what the company's public materials show about the business.
The problem it targets
Large companies often wait weeks or months to collect money they have already earned. Invoices go unpaid because a purchase order is missing, a price doesn't match or the bill went to the wrong person, and finance staff spend their days chasing customers and reconciling payments by hand. Stuut's estimate is that a broken order-to-cash process can cost a company around 5% of its revenue, close to $1 trillion a year across the Fortune 500. It puts the money tied up in receivables worldwide at $16 trillion. Those are the company's own figures, but they show the size of the opportunity: every business that invoices other businesses is a potential customer.
How the product differs
Most accounts receivable software finds a problem and hands it to a person: this account is overdue, this payment didn't match, this deduction needs review. Stuut's pitch is that its software finishes the job. It contacts customers by email, text and phone, logs into customer payment portals, applies cash to invoices and investigates disputes, carrying the details of a transaction from one step to the next. It runs on top of existing ERP systems; Honeywell uses it on a legacy SAP installation. Stuut plans to add order management and credit evaluation next, which would extend the product further up the order-to-cash chain.
Progress so far
Stuut has more than 150 customers, including Fortune 50 and Fortune 500 companies, and more than $3 billion has moved through its platform. A ZoomInfo case study shows $21.2 million collected on invoices Stuut worked. Days sales outstanding fell from 51 to 40, and first contact with overdue accounts happened more than 90% faster. Customers are also widening their use: ZoomInfo added disputes, and Bishop Lifting runs collections, disputes and cash application across 45 branches.
Who sits on the board
As of September 2026, Stuut's directors are Tarek Alaruri, Steve Sarracino, Seema Amble and Julian Marcu. Sarracino is a founder and partner of Activant Capital. Amble is a partner at Andreessen Horowitz focused on SaaS and B2B fintech, and Marcu is a vice president at Insight Partners, the round's lead investor. In November 2024, Alaruri was the only director; the other three joined later.
Risks and open questions
Accounts receivable automation is a crowded category. ZoomInfo was already running collections on HighRadius, an established vendor, before it adopted Stuut, and ERP providers are adding AI features of their own. Most of the performance figures above are self-reported. Software that calls and emails customers about money they owe also carries relationship and compliance risk if it misjudges tone or timing; Stuut's case is that its system knows when to back off and when to hand a case to a person. The funding totals show how much was sold and to how many investors, but not the share price or the company's valuation.
