The money is nice but just enough to allow us to continue working for 6 months or so. And the networking is certainly useful in the long run. What I'm most looking forward to, though, is the mentorship portion.
Specifically, I personally want to learn:
* how to run a Beta with the highest standards
* how to grow my organization and be an effective leader
* how to work with other organizations (partners, customers, etc) at a company level
Those are all things I've done in an individual capacity but not as the leader of my own company.
