Could NEVER understand what the heck they do and how they got $75M. Just sounded like they were a law firm specialising in start ups. Big whoop.
Justin Kan sold Twitch to Amazon for nearly $1B after 7 years, Socialcam for $60M in 18 months, and Exec for "under $10M" in 2 years.
That's how he raised $75M. The company/product was completely irrelevant.
