Stuut raised $52.5M to send AI agents after unpaid invoices. It says the software cuts invoice delays fast enough to chase real cash, not just tidy paperwork.

Stuut has raised a $52.5 million Series B to push its AI agents deeper into enterprise finance. Insight Partners led the round, with Andreessen Horowitz and M12 joining in. The company says the deal closed in 24 hours, and it brings total funding to $93 million, just 10 months after its Series A.

The pitch is simple enough to sting. Enterprises get stuck when a purchase order is missing or an invoice is challenged, and then people end up clicking through portals, sorting deductions, and chasing replies by hand. Stuut wants software to do that work instead. Its agents contact customers by SMS, email, and phone, log into accounts payable portals, reconcile incoming cash, and keep moving through the next step with the earlier context intact.

The company says the system is already doing a lot of the grunt work. It claims 81.7% of outbound collections activity runs without human involvement, and 95% of incoming payments are matched automatically. Customers, Stuut says, have cut days sales outstanding by 47%, though that figure is self-reported. The business also says its software plugs into ERP systems, bank accounts, CRM tools, and payment systems, and can go live in days.

There is no subtlety about the lock-in story, either. Stuut says every interaction makes the product harder to replace because it builds a living memory of how each customer pays, which portals it uses, and what tends to break. That may sound like a sales pitch with the volume turned up, but it is also the point: once the machine knows the mess, it becomes the thing most likely to survive the mess.

The new money will go toward meeting what Stuut calls overwhelming demand and expanding into the financial infrastructure around each transaction, from credit and lending to the movement of funds. The company, founded in 2024, was started by Tarek Alaruri, Ben Winter, and Miraj Mohsin. Alaruri previously co-founded Fairmarkit and served as its chief operating officer.

My take — AI-written commentary, not fact-checked reporting

This is the kind of automation that finance teams will buy because they are tired, not because they are dazzled. The real open secret in enterprise AI is that the winning product is often the one that owns the ugly workflow and remembers every exception. Everyone else can keep pitching copilots for the happy path.
