Personally, I'd be delighted if somebody could convince me the answer to my question was "yes". But I'm staying skeptical.

Specialized cofounders is a much less dangerous situation than outsourced core tasks. There are some events of companies failing or people getting really bad deals because the cofounders didn't all have the complete picture on their heads, but since they normally work in close contact and have the same interests, this is rare. Completely outsorcing those tasks completely remove both the proximity and interests alignment.

Yet, I think you are right in that some service that would watch what I'm doing and tell me "now, you need to do X", "you should have done Y", or "don't ever do Z again!" would be valuable. I'd call that "tutoring", not "outsorcing", and I have no idea if somebody does it.
