Nitpick: by definition, great businesspeople have lots of money (value).
You should say that business people with an unknown track record are possibly undervalued.
Which is really not saying anything at all, other than it's hard to tell the future.
The nitpick offers an interesting perspective, and it's well received, but I think it's orthogonal to my point.
In general, I think there's a common misunderstanding between these two camps, especially w/r/t their intersection in the software industry. Just as it's not fair for a businessperson to assume that all technical co-founders are interchangeable ("He's just a skill set"), it's not fair for technical co-founders to assume all business co-founders are worthless ("He's just a rolodex").
There are lots of good "business people" who have spent much of their careers as employees rather than owners. They did their job, they got paid, but even if they were stellar, they probably weren't paid an order of magnitude more than their peers. (As there are many fantastic engineers without patents and/or high profile products.) This may be why they're trying to do a startup rather than switch to a new job.
Try working a few times for some not-so-great business people and you'll learn that the good ones are often undervalued.
