I am wondering what are the areas in Linux/open-source where an Entrepreneur can build their career. To be a successful Entrepreneur you always need money/funding and the business should be ever-flourishing. You can’t ask for money (in most-general-case, not always) from someone who use your piece of code until and unless you build something like (RHEL, SLES, etc).
I don’t want to build my career around hosting business. So what I am left with? Any suggestion in this regard is appreciated.
