“blitzscaling. It is an idea that applies to many different industries, as he and Chris explain in the last section of this book. But prioritizing speed over efficiency—even in the face of uncertainty—is especially important when your business model depends on having lots of members and getting feedback from them. If you get in early and start getting that feedback and your competitors don’t, then you’re on the path to success. In any business where scale really matters, getting in early and doing it fast can make the difference. This is especially true for two-sided business models, where you have two user groups that create positive network effects for each other.

Uber wants to attract drivers as well as riders.”
