I'm a little clueless, in what environment is this sort of time frame reasonable? I'm guessing this is not a software project, or exists in a slow moving niche?
Currently I'm estimating the effort to be 5,500h. I really started in 2021 and will probably launch somewhere in 2026. So it is 5 years hustle to put almost 3 years of full time work while also making a living working for other people.
My self funding strategy was small time freelancing, which was ok for a short time, but when I found out it's going to take more time I'm spending now a lot of time to prepare to get a full time job instead and lower the personal life sacrifice. I guess if I had a well-paid job from the start and I was willing to sacrifice more personal life, I would get there faster - but either way it would take some time.
