The generative video pioneer building general world models for media and simulation
HQ: New York, NY | Founded: 2018 | Employees: ~100-250 (reported ranges vary; no official count) | Stage: Private; $5.3B valuation (Feb 2026); Lionsgate minority equity (Jun 2026) | Website: https://runway.com
Runway is a generative-AI research and product company founded in 2018 in New York by Cristóbal Valenzuela, Alejandro Matamala, and Anastasis Germanidis, who met in the NYU Tisch ITP program. It shipped commercial text-to-video for the first time (Gen-1, Gen-2), co-created Stable Diffusion, and now produces the Gen family (Gen-3 Alpha 2024, Gen-4 2025, Gen-4.5 2025, Gen-4 Turbo/Images), the GWM-1 general-world-model family (Dec 2025), and editing tools (Aleph in-video editor, Edit Studio, Act-Two). Runway also hosts third-party models (Veo 3/3.1, Sora 2 Pro, Kling) and its own Dev API. It has raised approximately $860M across nine rounds, including a $308M Series D at ~$3B (Apr 2025) and a $315M Series E at $5.3B (Feb 2026), both led by General Atlantic, with a Lionsgate minority-equity investment in June 2026. In February 2026 Valenzuela and Germanidis became co-CEOs. Production customers include Netflix, Amazon's House of David, Lionsgate, AMC Networks, and Bertelsmann; fiscal 2025 revenue is estimated at roughly $84-90M by third parties.
Runway is the closest thing generative video has to an operating system: it owns the model layer (Gen family, GWM-1), the product layer (consumer app, Enterprise, Alembic-like editing tools), and the pipeline layer (Runway Studios, AI film festivals). The 2025-26 story is brutal winner economics - Gen-4.5 topped Artificial Analysis' text-to-video charts while Sora 2 and Veo 3 chased it, and the company raised twice in eleven months ($308M at ~$3B then $315M at $5.3B) with General Atlantic anchoring both. The bull case: media deals (Lionsgate equity + joint IP, AMC, Bertelsmann, Netflix production use) convert into durable Hollywood pipeline, and GWM-1 opens a second market in real-time world models for robotics. The bear case: thin disclosed revenue (~$84-90M FY25), an artists' class action that survives motions to dismiss, and a credit-pricing model under consumer scrutiny.
