The reason why so many founders are finding success in

B2B

SaaS

is because of how slow incumbent organizations move.

It's expensive to create the simplest of

software

within these established walls. You can't just get started hacking on the cheap as there's a bunch of bureaucratic boxes that need to be checked off before you can even begin brainstorming. Once something tangible has been spec'd out, there are bureaucratic boxes along the entire development.

Because this makes it nearly impossible to create anything actually tied to the contemporary way we work, I see the rise in B2B SaaS as similar to how people in power outsource violence to organized crime. Politicians can't be connected to violent acts so they need to rely on organized crime to send over goons and threaten or mess up people who might be standing in the way. 

The contemporary SaaS founder is ruthless. Find overseas developers and designers. Scrap to do unscalable things to ensure customer happiness. All things that are too dirty and close to the mud for enterprise to do.
