Kathleen Kelly Janus, a lecturer at the Stanford University Program on Social Entrepreneurship and the founder of the successful social enterprise Spark, set out to investigate what makes a startup succeed or fail. She surveyed more than 200 high-performing social entrepreneurs and interviewed dozens of founders. Social Startup Success shares her findings for the legions of entrepreneurs working for social good, revealing how the best organizations get over the revenue hump. How do social ventures scale to over $2 million, Janus's clear benchmark for a social enterprise's sustainability? Janus, tapping into strong connections to the Silicon Valley world where many of these ventures are started or and/or funded, reveals insights from key figures such as DonorsChoose founder Charles Best, charity:water's Scott Harrison, Reshma Saujani of Girls Who Code and many others. Social Startup Success will be social entrepreneurship's essential playbook; the first definitive guide to solving the problem of scale.
