Back when mobile phones had green screens with black dots on them, Andy Nulman founded Airborne Mobile. In one year, the company went from $2M in revenue to $20M, driven by the explosion in the adoption of mobile devices. Leveraging his client list, Nulman sold 85% of Airborne Mobile for over $100M and retained 15% of the company—a position he would later expand in a strange twist of fate.
