Runway builds AI systems for generating and editing video — and is now pivoting that capability toward "world models," AI that can simulate realistic, physics-aware environments rather than just produce footage. Its core product is a subscription platform and API that lets creators, studios, and enterprises generate high-quality video from text or images using its Gen-4/Gen-4.5 model family. Revenue comes from tiered individual subscriptions and per-seat enterprise contracts. Customers include every major Hollywood film studio, advertising agencies, gaming studios, architecture firms, and — increasingly — robotics and autonomous vehicle companies that use simulated environments to train AI systems. Founded in 2018 in New York, it is co-led by CEOs Cristóbal Valenzuela and Anastasis Germanidis. The company positions itself as a platform that hosts both its own models and third-party models (Kling, Sora, Veo 3), making it a neutral creative OS rather than a single-model bet.
