Ian Greenblatt built his career as an operator before moving into venture, co-founding three companies (one sold to Motorola for $186M) and working at places like J.D. Power and Google, with legal training that he's used to help turn technology platforms into real businesses, especially in video, cable, and telecom. He's known for explaining why corporate-startup partnerships often fail due to communication gaps and for pointing out that enterprise deals need an internal champion to push them through procurement and legal, and he's been open that after 40 he only takes on work that genuinely interests him and avoids difficult people.
