Scheduling, invoicing, tutor pay and client billing for tutoring agencies — built inside one, sold to 1,800+ firms.
Will it work? · our read
Built from within. A tutoring agency, frustrated by bad admin tools, coded its own — then sold it to 1,800+ rival agencies. Vertical SaaS from an insider, still $0-funded.

Starter Story — We Built A $1.2M/Year App For Tutors (2021, founder interview)Latka — TutorCruncher: $1.7M (2023), $3.1M est (2024), $0 raised, 32 staff; page notes no founder interview on fileTutorCruncher — About: founded 2013 inside a tutoring agency, 1,800+ companiesPydantic — Samuel Colvin, co-founder & creatorTutorCruncher — pricing (from £25/mo plus payment fees)
Revenue is founder-stated, not audited. Colvin told Starter Story in 2021: about $100K/mo ($1.2M ARR) — that is the headline figure, first-party and publicly disclosed. Latka's TutorCruncher page itself states it has recorded no podcast or interview with the company's management, and that its $1.7M (2023) and $3.1M (2024) figures are algorithmic estimations, not founder-confirmed — so neither is used as the anchor here. Bootstrapped and $0-raised are confirmed by both Latka and the founders. The Pydantic connection is confirmed first-party: Samuel Colvin is Pydantic's creator and TutorCruncher's co-founder/CTO. "1,800+ companies" is from TutorCruncher's own site. There is no documented drama here — they won on insider fit, execution and patience over 13 years. The "dies" AI/horizontal-threat scenario is [our read], not a reported event. We never score you.
