Runway

Overview

Runway is an applied AI research company founded in 2018 by Cristobal Valenzuela, Anastasis Germanidis and Alejandro Matamala Ortiz [7] that builds generative AI platforms for creating and editing videos, images and multimedia content [2]. Headquartered in Manhattan [13], the company develops text-to-video and video generative AI models aimed at filmmaking, post-production, advertising, editing and visual effects [17], with its model line including Gen-1, Gen-2, Gen-3, Gen-4 and Gen-4.5 [17]. Gen-4.5 generates high-definition video from text with native audio, long-form multi-shot generation and character consistency [6]. Beyond core video models, Runway ships Aleph 2.0, Act-Two, Edit Studio, Runway Dev and a consumer iOS app [16]. In December 2025, the company released its first world model [5]. Runway raised a $315 million Series E in February 2026 at a $5.3 billion valuation [3], with proceeds earmarked for pre-training next-generation world models for medicine, climate, energy and robotics [5].
