1. uptime monitoring service [1]. launched in 2019. decided to enter a crowded niche so as not to reinvent the wheel and try to figure out distribution, but gave up. sold in early 2021. total sales before selling: $1,686
2. notion backups service [2]. launched in late 2021, total sales $100k, while still growing ~60% YoY. in hindsight, I should have picked an adjacent niche, since this business is technically difficult and not as easy to sell as a Notion site builder, for example.
3. churn analytics for stripe [3]. got accepted to the stripe marketplace, but still haven't gotten a single customer because I haven’t marketed it much. I use it daily and it is very helpful. for that reason alone, i don't want to kill it.
