Sean Ellis is one of the earliest and most influential thinkers and operators in growth. He coined the term “growth hacking,” invented the ICE prioritization framework, was one of the earliest people to use freemium as a growth lever, and, most famously, developed the Sean Ellis Test for product-market fit (which a large percentage of founders use today to track if they’ve found PMF). Over the course of his career, Sean was head of growth at Dropbox and Eventbrite; helped companies like Microsoft and Nubank refine their growth strategy; was on the founding team of LogMeIn, which sold for over $4 billion; and is the author of one of the most popular growth books of all time, Hacking Growth, which has sold over 750,000 copies.
