Dan does not like self-introductions, especially those written in the third-person, so I am writing it for him. My name is Murray. And I am a human with a square jaw and strong features. [Hold it together, Murray, this isn't about you.] Fine. Dan Hammer was a co-founder at SpaceKnow which has seen some success, and SpaceNinja which has not. Dan was the Chief Data Scientist at the World Resources Institute and the co-founder of Global Forest Watch. This is Murray, signing off.
