Project 91 is a New York City-based promotion and production company founded in 2019 with a focus on house music and large-scale experiential events. Since live events returned in 2021, the company has grown from local parties into a major independent promoter producing hundreds of shows across New York, the Hamptons, Miami, and other markets. Its events tend to favor energetic, accessible house music, spanning tech house, melodic house, dance-pop, and crossover electronic sounds, with past bookings including Diplo, Tiësto, Loud Luxury, Gryffin, and Cheat Codes. Project 91 frequently builds shows around distinctive settings, from Manhattan rooftops and Brooklyn waterfronts to boats, warehouses, courthouses, and full-venue takeovers. Recurring concepts such as Friends In High Places and Palma Day Club pair destination-style settings with polished production and social, high-energy crowds. The company has also expanded into larger seasonal programming, including multi-event Halloween weekends and collaborations with major promoters such as Live Nation.
