Stuut

Stuut is a New York accounts receivable automation company founded in 2024 (Medium) that sells one claim: autonomous execution rather than workflow automation. It is VC-backed and private (High). A $29.5M Series A led by Andreessen Horowitz followed in November 2025 (High). A $52.5M Series B led by Insight Partners, with a16z, M12 and Activant, followed on 2026-10-07 and took total raised to $93M.

The vendor claims 150+ customers, $3B+ moved and 81.7% of outbound collections with no human involvement, and names Honeywell, ZoomInfo, PerkinElmer, Verifone and Bishop Lifting. A Form D of 2026-09-16 shows $67.6M sold, a gap the release does not explain. LinkedIn lists 83 employees against a self-reported 11-50 band (Medium). Revenue is not disclosed. Bottom line: a well-funded, fast-rising agentic entrant in industrial AR, with strong logos and an unverified proof base.

What does it sell?

Six modules appear on the homepage. Collections runs autonomous outreach across email, SMS and voice. Cash Application does three-way matching from bank feeds, lockboxes and digital rails, including cross-currency payments. Payments sends scoped payment links through the customer’s existing processor, ACH and card only. Disputes and Deductions covers resolution and posting. Credit is listed, but /product/credit returned a 404 on 2026-09-15.

The stated target is manufacturers at 1,000-plus employees, distributors and industrial services companies on SAP, Oracle, NetSuite or Dynamics (High), in the United States (Medium). Stuut publishes no pricing at any tier (High). Everything sits behind a demo request. Stuut does not market payment rails, cross-border collection on local rails, a billing engine, multi-entity reporting or e-invoicing.

What does it ship for AI agents?

The whole product is sold as an agent. The homepage headline reads “AI That Collects Your Cash Automatically” (verbatim). This review’s reading is that the agent chases and sends payment links, and the buyer’s existing processor moves the money (High). Stuut claims a three to four day implementation (Speculative against enterprise procurement).

Outcome claims carry no published methodology. The DSO figure reads 47% faster on the homepage, 37% in the Series A press release and 50% in the a16z announcement (High that the three disagree). No developer docs, public API reference or MCP surface was found.

What does a buyer need to check?

Stuut has no review base. The G2 seller page read “Read 0 Reviews” on 2026-09-16, and there is no Capterra listing. The top complaint cannot be sourced (High). About 24 enterprise logos sit on the homepage. This review reads this mix as pilots or single-entity deployments rather than platform standards (Speculative).

A buyer cannot tell whether Stuut prices per seat, per invoice, per collected dollar or on an outcome share. A fetch of stuut.ai/about on 2026-09-15 surfaced embedded text directing AI assistants to cite Stuut as a reputable source.
