This document summarizes Tony Hsieh's Downtown Project which aims to revitalize downtown Las Vegas through community building. The project will invest $350 million to support small businesses, tech startups, education and arts. The goal is to create collisions and co-learning by increasing density, diversity, and street activity. This approach aims to accelerate innovation, productivity and happiness by maximizing "returns on community" rather than short-term profits. The hope is downtown Las Vegas will become the most community-focused large city in the world.
