QUOTE : In the end, Airbnb’s founders realized that they wanted to take on the Samwers—and they wanted to win. But how? The key was an aggressive, all-out program of growth that we call blitzscaling. Blitzscaling drives “lightning” growth by prioritizing speed over efficiency, even in an environment of uncertainty. It’s a set of specific strategies and tactics that allowed Airbnb to beat the Samwer brothers at their own game. Just a few months later, determined to acquire the resources needed to outscale the Samwers, Brian raised $ 112 million in additional venture capital. Airbnb then embarked on an aggressive international expansion plan, including the acquisition of Accoleo, a smaller and more affordable German Airbnb clone, that allowed Airbnb to compete directly with Wimdu in its home market. By the spring of 2012, Airbnb had opened nine international offices, setting up shop in London, Hamburg, Berlin, Paris, Milan, Barcelona, Copenhagen, Moscow, and São Paulo. Bookings had grown ten times since that previous February, and in June 2012 Airbnb announced its ten millionth booking. “The Samwers gave us a gift,” Brian admitted many years later in our Blitzscaling class. “They forced us to scale faster than we ever would have.” By choosing to grow at a breakneck pace, Airbnb had achieved a dominant position in its market.
