There's an angle to consider – why is it that people who are technically skilled and financially experienced do not take on venture funding and build billion dollar plus companies? [1]

Perhaps, they know (from business experience) that the VC treadmill is not in their best interests, when everything about that life is considered! :)

Perhaps investors actually benefit from the naïvete (read: not incompetence, just naïvete) of their portfolio companies?

It's a symbiotic relationship, but there's a reason that the road between founder and VC is generally a one-way street.

[1]: There are notable exceptions to this observations. They're worth understanding, too.
