Key Points

  • Stuut raises $29.5M Series A led by Andreessen Horowitz to automate accounts receivable for mid-market industrial companies using AI phone calls, emails, and messaging.
  • The company charges a flat monthly fee anchored to the $60,000 cost of hiring an accounts receivable worker, rejecting outcome-based pricing to keep customer buying decisions simple.
  • Stuut claims customers collect 40% of overdue invoices within six months and deploys in three days, targeting unglamorous businesses in the country's middle where cash flow timing matters acutely.

Summary

Stuut has raised a $29.5M Series A led by a16z to automate accounts receivable through AI phone calls, emails, SMS, and WhatsApp — replacing the manual follow-up work that typically falls to finance teams at mid-market industrial companies.

The company's founder positions it squarely in the middle of the country, serving customers like Bishop Lifting and PerkinElmer rather than coastal enterprise software buyers. The pitch is operational and concrete: Stuut says customers collect 40% of overdue invoices within the first six months, and Bishop Lifting cut its past-due invoice rate by 35%. Deployment takes three days, including for Fortune 100 companies — a claim the founder acknowledges most people initially doubt.

How the product works

Stuut runs both outbound and inbound collections. On the outbound side, the AI contacts customers with overdue invoices via phone, email, or messaging, and can send payment links directly in the conversation. On the inbound side, it sits behind an IVR system and answers invoice queries — pulling up account details and responding instantly without a human. The founder's framing is that accounts receivable staff shouldn't have to choose between chasing invoices and attending their kid's game; the AI works the 5-to-9 window after the team punches out.

Pricing

Stuut charges a flat monthly fee rather than seat-based or outcome-based pricing. The anchor is the cost of the human alternative: the average U.S. accounts receivable hire earns $60,000 before benefits and takes three to four months to onboard. Stuut frames itself as a cheaper, next-day alternative. When pressed on whether outcome-based pricing — along the lines of what Palantir's Alex Karp has argued for — would better capture the value delivered at scale, the founder holds his ground. He says simplicity is a competitive advantage when buyers are already overwhelmed by complex software pricing and sales pitches from vendors who've been rebranding as AI since 1997.

The customer base is deliberately unglamorous by Silicon Valley standards: established businesses in the middle of the country, where AR isn't anyone's primary job and cash flow timing matters acutely — especially around bonus season.
