I did. And I should have done it sooner. My situation was that of a technical founder who later recruited a few cofounders. After about a year working on the project, I lost interest in the problem being solved, and realized I couldn't stand the people I had brought on. But there were more of them than me, they were on the board as well, and we were part of an incubator-type program.

Not quitting sooner made me feel trapped with my team, which increased resentment amongst all members, which ultimately led to burning bridges. The real concern came when I realized that they actively worked to ruin my reputation within our network. Kind of shitty. But what's done is done, at this point I'm just wrapping up formal paperwork to cancel my shares, leave, and find whatever's next in life. Silver lining: I'm glad this experience happened earlier in life than closer to the peak of my career.

My biggest regret was not being forthright with my intentions to leave earlier. As a result, responsibility was placed on me, I failed to deliver, and it lead to these bad falling-outs.

Advice? Exit gracefully and professionally, wrap up lose ends, and try to keep people as happy/understanding as possible, even if you dislike them. Oh and get paperwork in order. Best of luck.
