Traction is a guide to getting customers, written for startup founders, marketers, and those interested in how today's startups grow and get traction. This book shows you how the founders of several of the biggest companies and organizations in the world like Jimmy Wales (Wikipedia), Alexis Ohanian (Reddit), Paul English (Kayak.com) and Alex Pachikov (Evernote) have built and grown their startups. We interviewed over forty successful founders and researched countless more growth stories to pull out the repeatable tactics and strategies they used to get traction.
