The corporate world is littered with them (esp. at medium-scale), but you can't magically discover them by reading on the internet.

Feels like most of the problems in that class I’ve stumbled upon were not viable. Not because there wasn’t a need but rather because the people suffering from the problem aren’t the ones signing the cheques, and the ones signing the cheques don’t really care about making the grunts’ work easier/more efficient since that’s what they’re being paid for: to toil.

What advice could you share for discovering this kind of problems that also can also be monetized?

Private equity is buying up as many as they can* but that proves they still exist!

Yes, absolutely. Looking at one right now actually (NDA, so I can't tell you about it but it's a gem).

Thanks. Reading a thread like this is sobering on the one hand, but also gives the feeling of "it's all pointless and crowded" :)
