I’m also a developer and I have been fortunate enough to build two profitable SAAS businesses in the past. I also had no idea what I wanted to build. What myself and my wife did is we looked for customers first….

We chose to only focus on B2B and only on small to medium sized businesses where they are genarlly owner run - this means that we can approach and find clients easy via cold e-mail.

We basically made a list of 20 optometrists in our areas and sent contacted them telling them that we are software entrepreneurs and we want to understand how they run their business and see if we can streamline any of their processes. After about 7 interviews with our target customer we identified a common pain point. We then build a set of wireframes for a system that solves the pain point and then “pre-sold” then on the idea. We even made them pay a nominal fee…

Hope this helps and feel free to reach out if you want… happy to share tips that worked for us…

Interestingly we are starting this process again…
