Currently doing that, with the following differences: - I am the cto for both companies - one of my startup is already 3 years old Even with a very low maintenance mode on my first startup, it's insane. Actually just one startup creation and bootstrapping is insane, so what happens is I just don't have time to manage and improve the first startup, yet it «kinda» works because it's a niche, with no competition, and my partner agreed to manage most of it while I am «less» available, but it really is a nightmare and it puts the business at risk. I know it's hard to choose («to choose is to renounce»), but my advice would be to focus on just one of them.
