Former founder and current parent here. My startup died because my kids were born.

I certainly couldn't do it, and I had a lot of advantages that most people don't (family help nearby, effectively unlimited runway). I tried for a couple years, but I just found I was so much slower as a father. There's no such thing as focus time with young kids in the house, you can't pull all-nighters to bang a feature out in a couple days, and then you lose a lot to context-switching overhead. And it's hard to get high-performers to work with you as a new parent, both because you have so much less time and flexibility to seek them out, and because they also know that your kids will (should?) come before the startup and "Why make someone a priority when you're just an option for them?"

Ended up going back to a big company known for work/life balance and generous paternity leave, where my efforts don't make a material difference to the success of the company. If there's effectively zero chance of success, it's not worth sacrificing time with my family to beat my head against the odds.
