About Instance
Instance is a physics-aware quality layer for AI-generated video, built to improve world models — scanning synthetic video for physics violations and layering in human judgment at scale to benchmark what reads as real versus fake. Built for teams betting on synthetic data who need a reliable quality gate. We're a team of technical cofounders from MIT who met in middle school!
