Stuut Raises $52.5M and Says Late Cash Starts Before the Invoice
Stuut says its agents run more than 81% of outbound collections with no person involved. Hackett's survey of North America's 1,000 largest public companies found DSO worse by 2.1 days, its third straight slip.
TL;DR
- Stuut raised a $52.5 million Series B led by Insight Partners and says agents run 81% of its collections.
- Its CEO and Hackett's new survey both trace late cash to terms, orders and billing set before any invoice exists.
- Hackett's 2027 survey will test it: a fourth straight year of worsening DSO, as vendors report cuts above 40%, would put the problem upstream of collections.
Stuut, an AI order-to-cash startup, raised a $52.5 million Series B on October 7. Insight Partners led the round, with Andreessen Horowitz, Microsoft's M12 and Activant joining, ten months after its Series A. SiliconANGLE puts its total funding at $93 million.
The operating claims are all Stuut's own. It says more than 150 companies use it, including Fortune 50 and Fortune 500 names. Its agents match more than 95% of incoming payments, and more than 81% of outbound collections run with no person involved. Stuut also says customers are cutting days sales outstanding by 47%.
In the announcement post, CEO Tarek Alaruri writes that the overdue invoice was usually "the last visible symptom" of something that went wrong earlier. He lists a missing purchase order, pricing that didn't match, an invoice sent to the wrong person, or context lost as the deal moved between sales, operations and finance. His customers are pulling the product in that direction.
Honeywell is moving Stuut into quote-to-cash, and ZoomInfo has expanded it into disputes. The new money goes to credit, lending and moving funds.
Stuut and Hackett both trace late cash back to the deal
An independent dataset landed two days earlier. The Hackett Group's 2026 working capital survey of the 1,000 largest public companies in North America found DSO got worse by 2.1 days, the third straight year it slipped. It worsened in 40 of 50 industries. Aggregate receivables grew 11%, nearly twice as fast as revenue, while days payable outstanding improved by 2.9 days.
Hackett's list of causes starts where the deal is struck, with credit decisions, negotiated payment terms, order accuracy and billing quality. Dispute management and cash application come after. The firm argues that companies working the whole path from order to cash are better placed than those focused only on collections.
Stuut's ZoomInfo case study says DSO improved from 51 to 40 days between July 2025 and July 2026, with Stuut "a key contributor to combined AR initiatives" at a company already running HighRadius and outside agencies. Computed from ZoomInfo's filings (quarter-end receivables over quarterly revenue, times days in the quarter), DSO was 57.0 days at June 30, 2025, per its 10-Q for that quarter, and 53.9 a year later. The direction matches, but the size doesn't, and both can still be honest.
Stuut doesn't publish its method, and ZoomInfo bills annually in advance, which inflates a revenue-based DSO. A case study can also measure only the accounts the agent worked. Monk, a rival that raised a $25 million Series A in April, claims a 40% average DSO cut for its customers. None of that shows up yet in Hackett's aggregate.
Sales sets the terms that decide when the cash arrives
ZoomInfo's own filings show where the next days come from. Its June 2026 10-Q says it's moving part of its per-seat business to a lower annual platform fee plus pre-purchased data credits from the third quarter. It also adds a risk factor warning that credit-based, usage-based or outcome-based deals may shift billings and collections to later periods. That's the same seat-plus-meter shift Microsoft and HG Insights are making, and it's a pricing and packaging call made by the people who own the price list.
Agents can run the chase. The terms were set at the deal desk.
With Stuut's agents running more than 81% of outbound collections, more of the days left over are ones a revenue team agreed to, and that binds Monk and every other vendor selling a DSO cut as much as it binds Stuut. Three of the gaps Alaruri names (a missing purchase order, pricing that didn't match, an invoice sent to the wrong person) are set before any invoice exists. ZoomInfo's move to credits from the third quarter, a call made by the people who own the price list, carries its own warning that collections may shift to later periods.
A buyer holding ZoomInfo's 10-Qs can recompute Stuut's reference case and get 57.0 to 53.9 days, not 51 to 40. So far, Stuut has published a 47% average cut and no method.
Our bet is that CFOs at companies buying these agents start asking CROs for DSO next to bookings when 2027 comp plans get set, because the late cash an agent can't reach traces back to terms sales agreed to. Hackett's 2027 survey will test the premise. A fourth straight year of worsening DSO, while vendors keep reporting cuts above 40%, would put the problem upstream of collections.
Once software runs the chase, more of the days left over are ones a revenue team agreed to.
Hackett's 2027 working capital survey of North America's 1,000 largest public companies will show whether DSO slips a fourth straight year after worsening 2.1 days in 2026.
