Decart, a vertically integrated AI research lab specialising in real-time video and world models, has raised $300 million in a round led by Radical Ventures. NVIDIA, Adobe Ventures, Toyota Ventures, and eBay Ventures joined as new investors alongside returning backers Sequoia Capital and Benchmark. Amazon is a strategic customer, and individual backers include OpenAI co-founder Andrej Karpathy and former Disney CEO Michael Eisner.
The company’s core infrastructure product, DOS 2.0, delivers over 1,600 tokens per second for agentic inference — roughly eight times the industry average — and full-HD video at up to 100 frames per second across NVIDIA, Google, and Amazon hardware.
Built on DOS, Decart’s two model lines address distinct markets: Lucy powers real-time immersive experiences across gaming, e-commerce, and advertising with sub-30-millisecond response times, while Oasis targets physical AI applications including robotics and autonomous vehicles through physically accurate real-time simulation. Both updated versions launch in the coming weeks.
