I am an undergraduate. The more I look at job listings, the more I want to work towards building a startup.

I have an idea and I'm working on the prototype. I'm planning on presenting it as a minor project during my next semester and use this to gather feedback on it from my professors. I already have a fellow classmate excited and willing to work on it.

Is it fine to be a founder while being an undergraduate or is it better to first have a relatively stable income first?
