David Rucker

American businessman, inventor and entrepreneur. At the age of 14 he was arrested on suspicion of hacking into the Department of Defense systems, but was never charged with a crime. Attended MIT where he graduated summa cum laude in Electrical Engineering. Formed a satellite communication company in 1995 (at the age of 25) and created the first broadband wireless network.

MA35TRO. Communications company founded in 2005 with the combined assets of R2 Communications and Rucker's primary competitor at the time, K2 Enterprises. The '35' in place of 'ES' is both an allusion to Rucker's age when he became a billionaire and an homage to 'hacker speak.'
