Ask HN: How do I quit my own startup?
4 by whateveracct | 0 comments on Hacker News.
I'm a technical cofounder (with one other non-technical cofounder) of multiple years now. The company itself is still alive and kicking. Getting customers, evolving for product-market-fit, has runway, etc. The problem is I don't want to work on this project anymore. It takes a lot of my time to be grinding out features for my cofounder, and I have a bunch of other ideas & pursuits that are more aligned with my career & life goals. I would be happier if I had time to pursue them in earnest. But I'm not sure how to pull the plug. There are other engineers on the project, but I'm still who designed & built most of the system. I've also had a lot of input on product direction, in ways that I think have been important. That said, my main skills are technical. But the company hasn't really required me to push my abilities lately, and the speed of the company isn't super dependent on engineering velocity anymore (we're way past MVP.) Any tips? Or anecdotes of similar situations? Both for handling the quitting itself (and potential meltdown from my cofounder) and for now to do right by the company (and my investment.)
