I love this! The numbers are wrong though. Over time the developer will get resentful. Imagine that the developer created a SaaS site that brings in 50k a year, after a few years of dev (which I have). Anyone would feel resentful about paying an ongoing 50% "tax" to an initial investor. In the 50k/year scenario the investor get's a 5x on investment for years to come. That would be an awful feeling for the developer who's putting in the ongoing maintenance effort. A better idea would be for the investor to claim 50% until capital investment was recouped, then gradually scale back. - So, 50% until the $8k was paid back. - Then 25% until a 2x return. - Then move to a 10% ongoing royalty fee. This excites and incentives the developer to keep building things out knowing that one day they will get the the 90% lions share of profits. It also works for the investor who can rinse and repeat the process with multiple developers.
