I guess that's a limit of your experience :)
I'm in a space that doesn't remotely interest VCs, it's not a regulated industry, and we're not a consulting company. Actually we're in 3 such spaces.
I also teach other (working) developers and while some are in health care the vast majority are unregulated.
But to be fair, you've likely never heard of us, or our ilk. We do the boring office software that underpins every boring industry. We're not self-driving cars or exoskeletons, we're data in, data processing, data out.
Our market isn't sexy enough, or wide enough for VCs, we don't need millions of $ anyway, so we've never bothered to ask for it. We do boring things like make a profit, and fund growth out of cash-flow. We hire slowly, and we don't do layoffs.
We have lots of competitors just like us.
