Dan sold his last company to Google. His last side project was Robot Turtles, the best-selling board game in Kickstarter history. He builds drones, authored Hot Seat: The Startup CEO Guidebook, and his seven year old twins regularly beat him at the game Werewolf.
Mark did the mechanical engineering, electrical engineering, firmware, and v1 software at the past two companies he founded. His most recent exit, Cequint was for $112M. He built a combination plasma torch, 3D printer, laser, & milling machine in his garage. For fun.
