I heard about startups that do something like make medical insurance billing easier. That raises a lot of questions, actually.
* How does one even learn that is an issue?
* It seems like something where getting started is driven entirely by having contacts in the industry.
* There has to be a ton of prohibitively expensive red tape to cut through. Would you just pay a lawyer to figure all that out? Lawyers are expensive!
* It doesn't seem like something that really makes the world better although I'm sure you could tell yourself that it does if it was your business. Is having your business do something you consider positive important?
* Where do you get the knowledge you need to get started in an industry. Say you're really only good at programming and want to start a ...fashion business. How do you even start? It can be hard to use Google when valuable information is buried under an ocean of click bait articles.
