All of your exit numbers seem crazy high. I'm left wondering if it's just wishful thinking, or if I'm way underestimating how much companies will shell out in talent acquisitions.
One number that I know for sure (it was publicized at the time) is Omnisio for $15 million. At that point it was about six months or so into the life of the company, which seems crazy high to me.
TechStars at least publicizes whether the exits are > or < $2million, which can be a helpful guide...
