In 2013 Evan Spiegel, the brash CEO of the social network Snapchat, and his co-founder Bobby Murphy stunned the press when they walked away from a three-billion-dollar offer from Facebook: how could an app teenagers use to text dirty photos dream of a higher valuation? Was this hubris, or genius? In How to Turn Down a Billion Dollars, tech journalist Billy Gallagher takes the readers inside the rise of one of Silicon Valley's hottest start-ups by covering Snapchat from the start. He brings unique access to a company Bloomberg Business called “a cipher in the Silicon Valley technology community.” Gallagher offers insight into challenges Snapchat faces as it transitions from a playful app to one of the tech industry’s preeminent public companies. In the tradition of great business narratives, the book offers the definitive account of a company whose goal is no less than to remake the future of entertainment.
