Decart

Decart is a AI Infrastructure startup based in Tel Aviv, Israel that has raised $453M in venture capital across 4 funding rounds since 2023. The company reached Growth Stage stage in October 2024 with a $21M round led by Sequoia Capital. Decart's investor base includes 12 institutional funds, with Radical Ventures leading the most recent equity round.

Decart is a Tel Aviv-based AI research lab founded in September 2023 by Dean Leitersdorf (CEO) and Moshe Shalev (CPO), both Unit 8200 veterans. The company develops three core product lines: DOS (Decart Optimization Stack), a chip-agnostic inference and training platform delivering up to 1,600 tokens per second and full-HD video at up to 100fps across Nvidia GPUs, Google TPUs, and Amazon Trainium; Lucy, a real-time world model for immersive video experiences with sub-30ms latency; and Oasis, a world model for physical AI targeting robotics and autonomous systems. Decart's technology enables real-time interactive AI simulations — including Minecraft-style world generation and physical environment modeling — on standard cloud infrastructure. The company raised a $300 million Series B extension in May 2026 led by Radical Ventures, with strategic participation from Nvidia, Adobe Ventures, Toyota Ventures, and notable angel investors including Andrej Karpathy. The round valued Decart at $4 billion, up from a $3.1 billion valuation in its $100 million Series B eight months earlier. Total funding stands at $453 million across four rounds since emerging from stealth in October 2024.
