Reactor Secures NVIDIA and Sapphire Ventures for Series A Expansion
Reactor, a developer platform specializing in real-time generative video and world models, has secured NVIDIA and Sapphire Ventures as new investors in its Series A round. The round is led by Lightspeed Venture Partners and aims to scale the infrastructure needed for complex AI systems that simulate and interact with dynamic environments. Reactor's platform combines a proprietary inference engine, global GPU cloud, and low-latency streaming layer, enabling models to run at over 60 frames per second with latency below 40 milliseconds. The platform is designed to abstract the complexity of deploying and scaling AI models, making it accessible through a unified software development kit and API.
The company's infrastructure is already in use across media and entertainment, with Hollywood studios, advertising platforms, and video streaming services running projects on it. Additionally, world-model laboratories and hundreds of developers are building applications on the platform. Reactor also sees potential in robotics, where it can run models in the cloud and stream observations and actions between the model and a physical system in real time. This capability allows robotics teams to train and evaluate robot policies in responsive generated environments without relying on physical robots or manually constructed simulators.
Reactor was co-founded by CEO Alberto Taiuti and CTO Bryce Schmidtchen, both former technical leads on Apple Vision Pro. Taiuti previously co-founded Luma AI and served as its CTO, where he helped develop infrastructure supporting 3D and video generation. The broader team includes engineers and researchers from companies like Apple, Meta, Google, Adobe, Replicate, and Microsoft. The platform is currently available through its SDK and API, with usage-based pricing that varies by model.
Key quotes from the company include Alberto Taiuti's statement that Reactor was built to allow developers to focus on creation rather than infrastructure. Anders Ranum, Partner at Sapphire Ventures, highlighted the platform's ability to solve infrastructure challenges for interactive applications. Ahmed Ahres, Head of GTM at Reactor, noted the shift from questioning the feasibility of real-time world models to exploring their production potential.
