3 significant failures, one of them big.

My conclusion is that for a multitude of reasons (most of which are well known) having involved investors reduces my chances of success considerably. And all they offer is money.

Money is cheap.

"And all they offer is money." - I think that's part of the problem you experienced. I've worked with some good investors in the past and they offered great mentoring and networks. A serious question would be "Did you go looking at them primarily for the money?"

I've worked as an analyst for a VC ($200M under management, so not huge nor small), and I can honestly say that you could find better advice by perusing the business book section of your local thrift store.

Part of the problem is the number of "dumb luck" one-time entrepreneurs that make it into VC Partner positions, that think they can extrapolate and apply their limited experience to anything under the sun.

Overconfidence in their own wisdom is hugely problematic, and most of them don't know the line between mentorship and being a de-facto CEO. Very rarely do you hear "I ran into a similar problem and this is how we solved it". Most of the time it is "Do it this way, just trust me because I had a $15M exit back in 1998", and occasionally it becomes "Do this or else we'll throw you out."

I had very different experiences, so tend to strongly disagree with the overall premise but not the average VC premise. There's a power law to VC's, as there is to much out here - the really great VC's are worth their weight and then some; the average to mediocre ones can be downright harmful.

Given that VC industry as a whole doesn't outperform major stock indices, it stands to reason that an average VC doesn't have that much wisdom to offer. Nevertheless, they offer financing and potential networks that you can mine.
