Why are people so obsessed with finding a co-founder?

Conventional wisdom from YC et al. Is that you need a cofounder because It derisks their investment if anything happens to you. It’s unlikely that you’re exceptional enough to be great at everything, so makes it more likely that the founding team is great at everything from tech to sales. It doubles or triples the amount of free work early on Creates an environment where ideas can be challenged Reduces chance of burnout. Finally, it’s also just more fun (if you find the right cofounder). There are obviously drawbacks to cofounders (risk of breakup etc) but on balance the VCs think cofounders are better, so founders buy into that, because they want to raise money. I say all this as a solo founder who has worked with a cofounder twice and broken up for various reasons, but I think when it works, it really works. The problem is that you need it to happen organically, it’s very difficult to force finding a cofounder. More on reddit.com
