Your product isn't just a project to you. It's years of thinking, your money, and often your reputation. You need someone who treats it that way, and who is still there when it starts to grow. That's how I've worked for 15 years. Some of the SaaS products I joined early went on to become large platforms, and I stayed with them for years along the way.
