If Levie or Altman end up reading this thread, I have some constructive criticism: I really think the first 30 minutes of Levie's talk were too much of a pitch for Box. I don't need to be sold on the company or technology when I'm learning. Simply stating what it is and how successful it has been grabs my attention and validates it's worth listening to. I found myself skipping forward over and over to get to the meat.
I enjoyed the latter half more. I think cutting the pitch down to 5 minutes and diving deeper into the lessons learned along the way could bring that talk up a level.
