This document summarizes Tony Hsieh's Downtown Project which aims to revitalize downtown Las Vegas through community building principles of collisions, co-learning and connectedness. The $350 million project will invest in small businesses, tech startups, education and arts with the goal of making downtown Las Vegas the most community focused large city in the world. The goal is to maximize long term return on community rather than short term financial returns by creating density, diversity and opportunities for serendipitous interactions.
