The definitive playbook by the pioneers of Growth Hacking, one of the hottest business methodologies in Silicon Valley and beyond.It seems hard to believe today, but there was a time when Airbnb was the best-kept secret of travel hackers and couch surfers, Pinterest was a niche web site frequented only by bakers and crafters, LinkedIn was an exclusive network for C-suite executives and top-level recruiters, Facebook was MySpace's sorry step-brother, and Uber was a scrappy upstart that didn't stand a chance against the Goliath that was New York City Yellow Cabs.So how did these companies grow from these humble beginnings into the powerhouses they are today? Contrary to popular belief, they didn't explode to massive worldwide popularity simply by building a great product then crossing their fingers and hoping it would catch on. There was a studied, carefully implemented methodology behind these companies' extraordinary rise. That methodology is called Growth Hacking, and it'spractitioners include not just today's hottest start-ups, but also companies like IBM, Walmart, and Microsoft as well as the millions of entrepreneurs, marketers, managers and executives who make up the community of Growth Hackers.Think of the Growth Hacking methodology as doing for market-share growth what Lean Start-Up did for product development, and Scrum did for productivity. It involves cross-functional teams and rapid-tempo testing and iteration that focusescustomers: attaining them, retaining them, engaging them, and motivating them to come back and buy more. An accessible and practical toolkit that teams and companies in all industries can use to increase their customer base and market share, this book walks readers through the process of creating and executing their own custom-made growth hacking strategy. It is a must read for any marketer, entrepreneur, innovator or manger looking to replace wasteful big bets and "e;spaghetti-on-the-wall"e; approaches with more consistent, replicable, cost-effective, and data-driven results.

Nick Kismet, the unstoppable hero of The Shroud of Heaven returns in a novella-length thriller. Kismet's search for the shadowy Prometheus group turns a corner when he receives an invitation to meet a mysterious informant. But instead of answers, he finds a beautiful reporter, hunted by vicious kidnappers and a fallen priest wielding the unholy power of the Judas Rope.

The greatest treasures from the ancient world have been brought together in one place-a magnificent floating exhibition aboard a luxury cruise liner-and the wealthy, powerful and famous have come to bask in the glow of ancient riches. Unfortunately, someone is about to crash the party in a big way. When Nick Kismet foils an attempted pirate takeover of the cruise ship and rescues the lovely Elisabeth Neuell-a former Hollywood starlet living the fairy-tale dream of royalty-little does he suspect that he has been drawn into a dangerous game controlled by diabolical occult scholar Dr. John Leeds...a game where the prize is an ancient source of mystical power, and where the stakes are the fate of the world. Joined by Al Higgins-the former Gurkha who once followed him into Hell-and Higgins' daughter Annie Crane, Kismet begins a desperate race to find the source of immortality and keep it from falling into the wrong hands. Surviving Leeds' web of intrigue and betrayal will put Kismet's courage and luck to the ultimate test. But fortune favors the bold!

Nick Kismet will go anywhere, do anything, to protect the treasures of the ancient world. But to stop an ancient symbol of power from becoming a weapon of unimaginable terror, he'll have to go further than he's ever gone before.... When an old college flame tries to entice him into smuggling a precious relic into the United States, Nick Kismet knows there's something more going on. But before he can get at the truth, a former rival appears out of nowhere, inviting Kismet to join him on a search for the mythical Golden Fleece. Although Kismet dismisses the possibility that the Fleece is real, he soon realizes that the search may bring him one step closer to unmasking the mysterious Prometheus group and solving the puzzle of his own origins. Accompanied by the beautiful daughter of a kidnapped Russian exile, Kismet follows in the footsteps of the legendary Argonauts, and sets out for the Republic of Georgia, the site of the ancient kingdom of Colchis. There he will discover that the Fleece is no mere story, but is instead the key to a devastating new weapon. Kismet's quest will take him from the deserts of North Africa to the urban jungles of Manhattan to the snow covered mountains of Georgia...but to keep the Golden Fleece from falling into the hands of his greatest enemy, Kismet will have to go... ...Into the Black.
