Hey there, I am Suhail -- one of the founders of Mixpanel.
It's true that they are. We tried to find (though we've not gone public about it yet) people to be at DDC that helped inspire us to build Mixpanel in the first place and people who are doing really interesting things with analytics today. We tried hard to focus on the content rather than just the pure celebrity of people at the event. Stay tuned.
