Runway Series D Funding: Towards a new media ecosystem with world simulators

On April 3, 2025, General Atlantic announced an investment in Runway, an applied AI research company building for the next era of art, entertainment, and human creativity. The following is a re-post of an article shared on Runway’s blog.

Today marks an important milestone as Runway announces a significant next step towards our goal of creating a new media ecosystem with world simulators. We’re excited to announce an expansion of Runway Studios, our first-of-its-kind AI film and animation studio dedicated to producing original content using the state-of-the-art foundation models pioneered by our research team.

To fuel this expansion and continue advancing our research in media generation, we’ve secured over $300M in Series D funding, led by General Atlantic with participation from Fidelity Management & Research Company, Baillie Gifford, NVIDIA, SoftBank and other new and existing investors.

Recently, we unveiled Gen-4, our next-generation series of AI models for media generation and world consistency. Gen-4 enables precise generation of consistent characters, locations and objects across scenes. These advancements aren’t merely incremental improvements; they form the foundation for an entirely new approach to media—an ecosystem built on AI systems that can simulate our world.

Our new funding will support these endeavors as we develop new AI research for new media. We’re also continuing to hire top researchers and engineers, with all open positions listed at runwayml.com/careers.
