Here is one random example that comes to mind. "Risk Management" is something every company needs to do or pretend to do.

So someone gets stuck with this responsibility and they create a spreadsheet that looks like: Department | Risk | Likelihood | Impact

So this is a fairly mediocre solution but it kinda works and "risk management" for "Small Company Co" becomes "Bob's thing".

Of course there is very likely software that already does this but in my experience it's usually what the hipster programmers call "enterprise garbage". You know what i'm talking about - buzzwordy site with stock photos, long annoying sales cycles, no online demo or sign up, some java server you have to deploy, and some extjs/jquery interface that is ugly and each click takes 5-10 seconds. You aren't competing with these guys, you're going after the long tail of small companies they are ignoring.

Your move is to register some fun name - "Riskly", "Riskque", "Risksalot", etc. Next, hire a graphic designer to put together a fun colorful site, hire a college kid to make a fun video with royalty free upbeat music and narration showcasing your app, and build a simple CRUD app with maybe some built in risks for certain industries and some cool simulations/reports.

So go spend a few years of your life and see if you can't 'Disrupt/Fix Risk Management'. Or go work for a large company for eight years, take all your earnings, go to Vegas, and let it all ride on a 10:1 bet. It works out about the same.
