Nicolas Chaillan is the chief software officer for the U.S. Air Force and one of France’s youngest entrepreneurs, having started his CEO career at 15. He’s also a technology entrepreneur, software developer, cyber expert, inventor and pioneer of the computer language PHP.

In this episode of Executive Perspective, Chaillan covers all of that and more, including why he decided to move to the U.S. and later join the departments of Homeland Security and Defense, how he has managed to create and sell over 180 software products to 45 Fortune 500 companies, and what exactly it means to be a chief software officer — a position created for him — in the federal government.
