Martin, I think we are really saying the same thing, and you absolutely drilled down to some very real characteristics that go into making a determination as to whether or not they "have the goods" to execute.
On a purely subjective basis, when I invest or when I make a determiation as to whether to take on a new client, probably the most important characteristic that I look for, and it's really difficult to articulate, because it's some of the characteristics you mentioned, but it's an overall sense that I get--as to whether or not, particularly as it relates to the CEO, the individual is, or over a period of time can become, an A+ CEO. Because, at the end of the day, it's more likely that an A+ CEO will hire A+ Team members, but a B+ Individual is unlikely to hire above him or herself. And if the team isn't stellar, it won't be fundable, so whether it's in consideration of an investment or taking that company on as a client, the end result is probably going to be the same.
Even if the individual hasn't matured into a stellar entrepreneur, at the the very early stages, a CEO with A+ CEO characteristics, that is passionate and believable, will be able to describe and articulate a vision that will make others want to quit good paying jobs and come to work with the individual for equity. And chase the dream.
I think one of the characteristics that often shines through in an A+ entrepreneur is an unbridled passion to solve a significant pain deeply felt by the entrepreneur. I recently bet on an entrepreneur that quit a very nice six figure salary and option package, rented out the 5 bedrooms in his Palo Alto house, and he and his wife are living in the garage, bootstrapping development with the rent. That's commitment and what George Zachary of Charles River Ventures identifies as the almost self destructive desire to win/achieve.
It's going to be interesting to hear Saeed's answer to Martina's question. Not only has he made pretty impressive bets over his 200 plus companies invested in, but he currently has, I believe, over 400 companies in Plug and Play in the Just the Sunnyvale facility.
