I've developed the product until it had a certain maturity. I've then onboarded two co-founders who also helped part-time. One helped with marketing, one with develoent. I've found them through YC cofounder match and the dev from GitHub OSS projects. Together, we've landed our first paying customer. With a few more leads in the pipeline, we were able to start the fundraising process.
We then slowly transitioned from side project to full time. The complete team is now full time for 2 months and we're very happy how things are going.
I can say that it was a damn struggle to get all this up and running with 2 young kids and without ruining the family. I'm thankful that my wife is very supportive. It's weird when your partner accepts that you work 3 hours per day on the weekend while the kids sleep. But there was no other way. It needed to be done. Of you really believe in what you do, it's possible, even with a family. If you have questions, please ask.
