Sometimes in business, success comes not by reinventing the wheel but by simply building a better mousetrap. That's exactly what David Karp did when he founded his microblogging site, Tumblr. This book introduces readers to Karp and follows him from his humble beginnings as a shy kid to the head of one of the most successful tech companies today. He grew his business simply because he believed he could build a simpler, leaner blogging platform that was easier to use. His idea was a hit, and Tumblr's success took off. As with most companies, though, Karp's business experienced growing pains from its rapid expansion and struggled to turn a profit. However, readers learn that Karp, the once introverted kid who transformed into a confident leader, is looking toward further growing Tumblr into an even greater success. With fact sheets on the founder and the company itself, readers see that it's possible to turn a simple idea into a revolutionary business.
