SaaStr·medium signal

SaaStr's teardown of vertical trades-software leader ServiceTitan shows it cleared $1B annualized (2026 revenue ~$961M, Q2 guide $284–286M, ~26% growth) with 110% net revenue retention and 81.3% platform gross margin. The signal for builders: fintech (payments/lending embedded in the platform) is the fastest-growing line, confirming the pattern that durable vertical SaaS monetizes the payment/financial flow of its industry, not just the software seat — the layer AI can't easily rip out.
