OpenFounders came to me when I was trying to find people to follow on Twitter, blogs and elsewhere. I searched the internet but didn't find an accessible and cohesive way of doing so.
At the same time, I had been wanting to learn how to develop SPAs. Learning React and separating front/backend was a skill I wanted to develop.
OpenFounders solved both those problems. I could learn React while also releasing a fun side-project. Furthermore, I could meet other founders and learn the details of releasing a software project.
