Runway

A New York video-generation company that followed its Gen series with GWM-1, a world model with a robotics variant.

Runway was founded in New York in 2018 by three co-founders — Cristóbal Valenzuela, Alejandro Matamala, and Anastasis Germanidis — who met at NYU's ITP program for art and technology. It became known for its Gen-series video-generation models (Gen-4.5 shipped in late 2025), and in 2022 it co-released Stable Diffusion together with the CompVis group at LMU Munich. On December 11, 2025, building on Gen-4.5, it released the general-purpose world model GWM-1: an autoregressive model that generates video frame by frame in real time and can be steered with inputs such as camera movement or robot actions; its GWM Robotics variant provides a Python SDK that generates multi-view future frames conditioned on robot actions, used to synthesize training data and evaluate policies in a virtual environment. On funding, it raised $315 million in February 2026 at a $5.3 billion valuation.
