AI business case studies: revenue and exits
These are case studies of businesses built on generative AI, image generation and LLMs, where the founder has publicly disclosed revenue or a sale price. Small Start records the monthly revenue, exit price and acquisition channels with sources.
AI numbers are easy to exaggerate. Everything here is a figure the founder published, with the source attached — including businesses that grew and were then shut down anyway.

36,500 subscribers, but two years of total revenue in the high hundreds-of-thousands of yen. An AI-explainer YouTube channel's hourly wage: ¥416
An AI-tool explainer channel grew to 36,500 subscribers two years after launching in April 2024. But two-year total revenue was only in the high hundreds of thousands of yen, recently a few tens of thousands of yen per month.

The turning point wasn't stagnation — it was the year-two conclusion that ad revenue had plateaued, reached after every stated goal had been met.
