(As an interesting aside - the first time I showed up to capture content, the group was understandably weary of a strange guy with a video camera, because as I've said on multiple occasions, the culture does not yet exist for content to be captured. But Alson sent me a great email after the event saying, "Your video from the last event was much appreciated." It's great to see groups embrace the capturing of content!)
I don't have the exact names of speakers (can someone pls add that to the comments below?) but I believe it was reps from Zong, Groupon, Simon-Kucher and Apsalar.
Here's the video of the event:
