I work for a company that was in the same class as ZeroVM. I'm not a founder but I was around for the second half of the 2013 program.

Of course Rackspace was involved but Cloud isn't a "powered-by" program like those with Sprint or Nike. Other than ZeroVM, I don't think Rackspace was seriously involved with any of the other companies in the class.

In my experience, Rackspace was pretty hands-off, both with Techstars and Geekdom in general. I think you're trying to insinuate something negative about their involvement when it was only (IMO) positive.
