One way to come up with ideas is prompt ChatGPT: “Give me a list of SaaS ideas I can build as a solo developer” and continue reprompting until you find something you like.

You should ensure it’s something you have at least a little passion for as you’ll be working on it for a long time, even after development. It’s okay to enter a market with competitors, even large ones, just niche down a bit more than them and create a better solution for your more targeted audience. It’s okay to have similar marketing and features but yes definitely don’t want to just build a copycat business.

Also don’t let doubt stop you before you start. I faced doubt so many times and tried to talk myself out of it at least once a week, but just pressed on and now my first start up is launched and live, still working on the getting customers part haha
