About Reactor
Reactor is a developer-focused company providing the infrastructure for real-time generative artificial intelligence (AI) video and interactive AI world models. Founded in 2025 and headquartered in San Francisco, the firm emerged from stealth on May 28, 2026, with $59 million in funding. The Series A round was led by Lightspeed Venture Partners, with participation from WndrCo, Amplify Partners, Sky9 Capital, and FPV Ventures.
Read full description
The company was co-founded by CEO Alberto Taiuti and CTO Bryce Schmidtchen. Both founders are former technical leads from the Apple Vision Pro team. Taiuti's prior experience includes co-founding Luma AI, where he served as CTO, building the infrastructure for a widely used 3D and video generation platform. The broader Reactor team comprises engineers and researchers with experience from major technology firms including Apple, Netflix, Meta, Google, and Microsoft.
Reactor's core offering is a platform that provides a unified Software Development Kit (SDK) and Application Programming Interface (API), enabling developers to build and deploy real-time, interactive AI applications with minimal code. The platform acts as a critical software layer between complex AI model labs and application developers, managing the complexity of deploying and scaling these systems. This infrastructure is designed to support a new category of media experiences that are dynamically generated and shaped by user interaction, rather than being pre-rendered. The company prioritizes interaction speed, aiming for visual latency below 50 milliseconds to enable true real-time responsiveness.
The business model is usage-based, with pricing tied to the type of model used, accessible via the SDK and API. Reactor serves developers across various sectors, with initial customer demand from media and entertainment, film and television studios, physical AI, and robotics companies. Strategic partners include Amazon Web Services (AWS) as the preferred cloud provider to handle the necessary compute infrastructure for real-time generative video workloads on a global scale.
