No, I tried probably for too long and the stress and workload was too much, I still have a bit of PTSD from it to be honest. B2C space with 7 day per week customer support, over 100k DAU. Only way to stay solo would have been to turn away sign ups or something like that.
It's not just you. I founded a bootstrapped side project/startup that has gone viral during COVID. It's been a wild success, people love the product, but going from solo to now a team of 5 in a period of 2 months and handling a huge amount of users has been stressful. Business-wise, I shouldn't be anything but super happy, and advisors say we've won a lottery, but honestly I miss having less responsibility (e.g. keeping people employed, duty to thousands of customers 24/7) and pressure (don't screw this up!). Don't get me wrong, the ride can be exhilarating and I'm sure I will look back on it one day with pride, but at times I yearn for the days of "just" being a freelance dev who had relatively low stress and tons of time for my wife and kids.
