Craigslist founder Craig Newmark launched a simple email list in 1995 that grew into one of the most influential online marketplaces in history. What began as an informal community bulletin for San Francisco events evolved into a platform that reshaped how people buy, sell, and connect online.
Unlike venture-backed startups chasing rapid scaling, Newmark prioritized transparency, low fees, and user control, principles that still define Craigslist today. This approach created a durable digital town square that remains central to online classifieds across the United States and around the world.
