I run a one-person business. I pay for 25 SaaSes

Well, they're either worth it or they're not. If they're not worth it then don't use them.

I don't mind paying for software subscriptions or services if they provide real value. If they don't provide value then I shouldn't be using them in the first place.

It’s not that he’s paying for 25 that’s weird, it’s that this is the volume you would expect of a 5-10 person team.

He’s not using all of that nearly to its capacity. Hire some people my guy.
