I actually think that’s probably not a good assumption. I know you’re being pejorative, but imagine a scenario where someone has been working for years as a payroll administrator or someone who’s been a consultant working on implementing payroll systems for decades. People learn the market and get sick of the status quo and have tons of new ideas. I could easily see someone get excited about a way to make their job easier, more fun, more efficient, etc. and go and launch a new payroll software startup that just improves everything.
My point is: good entrepreneurs are passionate about solving problems. Sometimes those problems might “seem” boring but don’t assume they are.
