Off topic question and probably a far too ambitious idea... but as a veterinarian, have you thought about working on improvements to the software that vets use?
About six months ago I was spending time with a vet friend, and was hearing stories about terrible user interface and ways the software was getting in the way. The story I most remember was a 60 second timeout requirement to enter patient data before the workstation locked and required logging in again, and that a logout while still typing would cause the current notes in progress to be deleted. I have no idea if those problems are caused by regulation (a kind of kitty HIPPA compliance) or just terrible UX.
I worry that vet software is probably a terrible market as well, with regulation and established providers, maybe it's a lower margin business (certainly not a profit center) and maybe edge cases for each vet practice in the US.
As someone with domain knowledge, perhaps that's a challenge you might consider, now that AI makes coding so accessible across domains now? Since I have zero domain knowledge, it seemed like something I could never help solve.
I am committed to some projects now, but I did a full analysis of projects to invest, used AI to validate ideas and so on.
My main goal was "solo founder projects as programmer" and one of them was software for veterinarians (second one was for golf tracks).
It is an interesting niche!
