Stuut has raised $52.5 million in Series B funding led by Insight Partners, with Andreessen Horowitz and Microsoft's M12 fund also participating, the company said this week. Stuut builds AI agents that automate the order-to-cash process for enterprises — reconciling invoices, following up with customers by text, email and phone, logging into customer portals, matching cash to invoices and resolving disputes. The company says the system now runs 81.7% of collections activity without a human in the loop, according to Tech Funding News.
Founded in 2024 by CEO Tarek Alaruri, a former COO at procurement software company Fairmarkit, along with Ben Winter and Miraj Mohsin, Stuut has now raised roughly $88 million in total.
That follows a $29.5 million Series A in November 2025 — also led by a16z — and a $5.9 million seed round; the repeat participation from the same investors suggests growing conviction in the category rather than a new investor discovering it for the first time.
“Enterprises evaluating Stuut and its rivals should ask what share of that 81.7% is low-complexity reminders versus genuine dispute handling.”
AI-driven collections has become a genuinely crowded field this year: competitors include Fazeshift, which has raised roughly $22 million total, along with Lunos, Round and Procuros, a European rival that closed a €20 million Series A around the same time as Stuut's announcement. With that many funded players chasing the same back-office workflow, differentiation increasingly comes down to integration depth with existing ERP and accounting systems, not just the automation percentage any one vendor claims.
The 81.7% automation figure is the number worth stress-testing, not just repeating: automating routine invoice chasing is one thing, but dispute resolution — the part of collections that actually requires judgment — is a much harder problem to hand fully to an AI agent, and the claimed rate doesn't distinguish between the two. Enterprises evaluating Stuut and its rivals should ask what share of that 81.7% is low-complexity reminders versus genuine dispute handling.
Enterprise customer names and retention data at Stuut's next raise would separate it from competitors still selling mostly on automation-rate claims; so far, it hasn't disclosed either.
