Steve Blank talks with students in Stanford’s first

Steve Blank talks with students in Stanford’s first Hacking for Defense class, in spring 2016. H4D, as it is called, gives teams of students unclassified, real-world DOD problems to solve. H4D has given rise to Hacking for Diplomacy, Hacking for Energy and other sister classes, now collectively known as H4X; the X can be any subject. (Photo by Rod Searcey, Stanford News Service)
