GoFundMe did this. The original version was for a client. Then they found another client and reused some of the code. Then another and reused more of the code.

When they went to go raise money the cofounders decided to just sell the whole thing. IIRC it went for $20m, but with zero dilution and a small team those were some BIG slices of a medium sized pie. I’d recommend: 1. Identify a solution that you’ve implemented in the past that you can simplify and sell. 2. Only do customizations to that solution for a high multiple (e.g. 5x your normal rate). Ideally if you’re disciplined, do not do customizations at all. #2 is the most important part. If you falter here though, the worst case scenario is you’ve made way more margin for way less work.
