Runway AI, Inc. (commonly known as Runway) is an American applied artificial intelligence research and technology company headquartered in New York City. Founded in 2018 by Cristóbal Valenzuela, Alejandro Matamala-Ortiz, and Anastasis Germanidis after meeting at New York University’s Interactive Telecommunications Program, the company was established with a mission to democratize advanced machine learning tools for artists, designers, and filmmakers. Runway has since positioned itself as a leading force in generative AI for multimedia, specializing in creative tools that revolutionize the video production, editing, and storytelling landscapes. The company operates under a Software-as-a-Service (SaaS) business model, offering tiered subscription plans alongside enterprise solutions and API access. Its cloud-based platform eliminates the hardware limitations traditionally associated with heavy rendering and processing, allowing users to execute complex AI workflows in real time from any standard web browser or an iOS consumer application. The technical core of Runway relies on sophisticated, proprietary multimodal foundational models—most notably its progressive model suites. Milestone developments include Gen-1, launched in February 2023 for video-to-video transformations based on text or image prompts, and Gen-2, introduced in June 2023, which pioneered commercial text-to-video generation from scratch. Furthermore, the company has announced newer architectures, such as its General World Models (GWM-1) and Gen-4 models, designed to build comprehensive multimodal simulators capable of fine scene and character control. Beyond its basic text-to-video capabilities, Runway offers a suite of interactive utilities known as "AI Magic Tools," which include specialized functions like intelligent video inpainting, outpainting, and motion brushes for granular content manipulation. These features have been leveraged in major Hollywood media and music productions, including the Academy Award-winning film "Everything Everywhere All at Once." In addition to enterprise and cinematic adoption, Runway actively contributes to open-source communities, having notably co-developed the initial version of the Stable Diffusion text-to-image model. The firm maintains active cross-industry partnerships, such as a 2024 agreement with Lionsgate Entertainment to build a custom generation model trained on the studio’s internal content catalog, and a 2025 content collaboration with AMC Networks. Financially, Runway has demonstrated substantial venture traction. The company has secured an estimated $860 million across multiple funding rounds from prominent tech investors, institutional funds, and corporations including Google, NVIDIA, Salesforce Ventures, General Atlantic, Amplify Partners, and Fidelity Investments. Following its $315 million Series E funding round concluded in February 2026, the company achieved a private market valuation of $5.3 billion. Runway maintains a growing global footprint with physical offices spanning New York City, San Francisco, Seattle, London, Tel Aviv, and Tokyo, continuing its expansion into the global media and creative entertainment technology industries.
