Reid Hoffman and Chris Yeh's "Blitzscaling: The Lightning-Fast Path to Building Massively Valuable Companies" is a must-read for founders looking to start and scale their business the most successful way possible. The book answers the question every founder has about how to make a startup into a global giant. Hoffman and Yeh's answer is "blitzscaling: a set of techniques for scaling up at a dizzying pace that blows competitors out of the water." Hoffman got his start in Silicon Valley as the COO of PayPal, then later cofounded LinkedIn. He is also a successful angel investor, who was one of the first investors in Facebook alongside Peter Thiel and is currently a partner at VC firm Greylock Partners.
