How new tech ventures become successful is pretty much alchemy, but how they start has followed two relatively common patterns for over 75 years. The first is the story of two people in a garage or a dorm room. Think Hewlett Packard or Apple; Facebook or Google. The other is when defectors from a large company go off to found a startup. Think the Traitorous 8 leaving Shockley Semiconductor to create Fairchild and eventually Intel.
