# Reactor: Real-Time AI Video Platform Raises $59M from WndrCo

> Reactor, a startup founded by former Apple engineers, has raised $59 million led by Jeffrey Katzenberg's WndrCo to chase a specific and hard target: AI video that generates in real time, with essentially no delay before the first frame. Most AI video tools today make you wait, but Reactor is optimizing for interactivity, where the video responds as fast as you can prompt it. Katzenberg's involvement is a signal in itself. The former DreamWorks chief backing a real-time video engine says the entertainment world sees interactive, generated video as the next battleground, not just polished clips for ad campaigns. Reactor is stepping into a crowded field that already includes Runway, Reface, and Descript, and into a market that has grown sharply as marketers lean on AI for video. The bet worth watching is whether low latency turns out to be the feature that unlocks genuinely new formats, think live avatars, playable scenes, or responsive advertising, rather than just faster versions of what already exists. Near-zero latency is the kind of constraint that, once solved, tends to reshape what people build.
