About

Decart is an Israeli vertically-integrated frontier AI lab co-founded in late 2023 by CEO Dean Leitersdorf and CPO Moshe Shalev, building real-time video and world models alongside an ultra-optimized inference and training stack (DOS) designed to make agents and reasoning models run smarter and faster 123. The company’s model lineup includes Lucy (a world model for immersive experiences) and Oasis (a world model for physical AI), with Amazon as a strategic customer running Decart’s real-time world model on its chips 12. The $300M round announced May 18, 2026 was led by Radical Ventures at a $4B valuation, with new investors Nvidia, Atreides Management, Valor Equity Partners, Adobe Ventures, Toyota Ventures, and eBay Ventures joining returning backers Sequoia Capital, Benchmark, and Zeev Ventures; angel participants include Andrej Karpathy, Michael Eisner, the Nintendo family, and Moritz Baier-Lentz 123.
