Details
- Reactor, a developer platform for real-time generative video and AI world models, emerged from stealth with $59 million in funding led by Lightspeed Venture Partners, with participation from WndrCo, Amplify Partners, Sky9 Capital, FPV Ventures and others.
- The company was co-founded by CEO Alberto Taiuti and CTO Bryce Schmidtchen, both former technical leads on Apple Vision Pro, and its broader team includes alumni from Apple, Netflix, Meta, Google, Adobe, Replicate and Microsoft.
- Reactor offers a unified SDK and API that lets developers build and deploy real-time interactive applications in a few lines of code, abstracting away the complexity of serving world-model–based video systems at global scale.
- Positioned as the infrastructure layer between AI model labs and application developers, Reactor targets media and entertainment, physical AI and robotics, and is already working with film and TV studios, robotics firms and world model developer Overworld.
- Amazon Web Services is Reactor’s preferred cloud provider, supplying compute and distribution for low-latency, large-scale inference, with the platform available now on a usage-based pricing model billed by model type.
Impact
By productizing infrastructure for real-time world models, Reactor lowers the barrier for studios, robotics companies and startups to build interactive, AI-native experiences. If it can reliably serve high-intensity video workloads, it may become a reference stack in the emerging real-time generative media and physical AI ecosystem, shaping how labs commercialize world models and how developers design immersive applications over the next 12–24 months.
