Reactor
Developer platform for real-time generative video and world models
About
Reactor (Reactor Technologies, Inc.) is a San Francisco developer platform for real-time generative video and world models. It abstracts away GPU provisioning, infrastructure setup and streaming so developers can build interactive, low-latency (sub-50ms) video experiences on many open and partner world models through one SDK and API, with usage-based pricing. It was founded in August 2025 by Alberto Taiuti (CEO, previously co-founder and CTO of Luma AI) and Bryce Schmidtchen (CTO), both former technical leads on Apple Vision Pro. It emerged from stealth in May 2026 with $59M in combined seed and Series A funding led by Lightspeed Venture Partners, and on October 5, 2026 announced that NVIDIA and Sapphire Ventures had joined its Series A.
