Investment Thesis
Decart is an AI research lab building real-time generative world models that power interactive entertainment and creative applications. The company's flagship Oasis model went viral as the world's first real-time AI-generated playable environment, and the follow-up MirageLSD pushed the boundaries of low-latency video transformation.
Founded in late 2023 by Dean Leitersdorf (CEO) and Moshe Shalev (CPO), Decart is based in San Francisco with operations in Israel. The company raised $21M in a Sequoia-led seed round in August 2024, followed by a $32M Series A led by Benchmark in December 2024 at a $500M+ valuation. In August 2025, Decart closed a $100M Series B at a $3.1B valuation. Remarkably, the company has spent less than $10M of investor capital while already generating millions in revenue.
Training AI models for robotics, autonomous vehicles, and gaming requires either expensive real-world data collection or hand-crafted simulators that never fully capture the complexity of physical environments.
Decart builds real-time AI world models that generate interactive, physically plausible environments on the fly — enabling agents to train, plan, and act in simulated worlds that are generated rather than programmed.
Decart's DIAMOND model demonstrated real-time world simulation at unprecedented fidelity, and the team has attracted attention from gaming, robotics, and autonomous systems companies seeking next-gen simulation.
World models sit at the convergence of video generation, game engines, and embodied AI — three massive markets all hitting inflection points simultaneously as compute costs for inference drop and model architectures mature.
