VAST builds world models that enable AI systems to understand and simulate complex environments.

A $140M Series A3 for world models signals that simulation-as-infrastructure is moving from research toy to production dependency—someone's betting this becomes the backbone for robotics, autonomous systems, or synthetic data pipelines. At this stage and size, VAST is likely burning cash on compute for training massive environment simulators and building out enterprise go-to-market. If you're building anything that needs to predict or control physical/digital systems (autonomous vehicles, game engines, industrial automation), watch whether world models become a commodity layer or stay vertically integrated—that determines your build-vs-buy calculus in 18 months.
