This document summarizes Zappos' Downtown Project which aims to invest $350 million to revitalize downtown Las Vegas. The project focuses on accelerating collisions, co-learning, and connectedness through initiatives like funding $50 million each for small businesses, tech startups, education and arts. The goal is to maximize long-term return on community rather than short-term financial returns and institutionalize luck through increased serendipity from a dense, diverse environment.
