Realistic income
RevenueCat’s Sub Club write-up says co-founders Brett Bauman and Zack Hargett bootstrapped Coconote to $6.7M in ARR and an exit to Quizlet in under two years, after reaching $1M ARR in four months with no paid ads. The business has since been sold. This figure is operator-reported, not independently verified, and may be out of date. This is one operator’s result, often after months or years of work, and doesn’t predict yours. Check the live source — numbers change.
Risks
- Recording classes needs permission from teachers and schools.
- Crowded category with free alternatives; Coconote itself was sold to Quizlet.
- Seasonal school usage.
- Startup cost and time to first dollar are not disclosed.
