'A must-read for everyone who cares about driving customer engagement' Eric Ries, author of The Lean Startup'The most high bandwidth, high octane, and valuable presentation I have ever seen on this subject' Rory Sutherland, vice chairman, Ogilvy & MatherNir Eyal reveals how successful companies create products people can't put down - and how you can too Why do some products capture our attention while others flop? What makes us engage with certain things out of sheer habit? Is there an underlying pattern to how technologies hook us? Nir Eyal answers these questions (and many more) with the Hook Model - a four-step process that, when embedded into products, subtly encourages customer behaviour. Through consecutive "hook cycles," these products bring people back again and again without depending on costly advertising or aggressive messaging. Hooked is based on Eyal's years of research, consulting, and practical experience. He wrote the book he wished had been available to him as a start-up founder - not abstract theory, but a how-to guide for building better products. Hooked is written for product managers, designers, marketers, start-up founders, and anyone who seeks to understand how products influence our behaviour. Eyal provides readers with practical insights to create user habits that stick; actionable steps for building products people love; and riveting examples from the iPhone to Twitter, Pinterest and the Bible App.
