I made that mistake of partnering up with non technical co-founder to build travel insurance "configurator" to get the best deal on travel insurance. Only I discovered there were more co-founders like his wife "to do some accounting" and his buddies to do whatever.

And I was the only technical person who was supposed to build the thing, to launch it and they were the ones nit-picking little stupid details that took forever to fix but didn't matter all that much.

In the end I spent 5 months working on it and we still didn't get any paying clients, but many more ideas on what else I should build "to get clients". I realized they suck at marketing and business side of things and they don't know shit.

If you're a tech person, don't make the same mistake I did. Most people don't understand marketing. Their ideas are shit. They don't know the technology. And YOU are the one who's gonna be doing most of the work. And THEY think that the business belongs to them because as someone said they "came up with the idea" that wasn't all that unique because everything that's needed under the sun has already been built. Many times over. They had just no idea that that's the truth. Now if they have the money and want to hire you to do the work, charge them market rate.
