What Decart does
Decart is a frontier AI lab that builds real-time generative video and interactive world models. Most video models today take seconds or minutes to render a single short clip; Decart's research focus is to push generation latency down to live frame rates and make video models steerable in real time, opening the door to playable AI worlds, live transformations of camera feeds, and interactive entertainment.
The company's first model, Oasis, is described as the first real-time video-generation model launched at scale — it can produce a playable AI-generated 'video game' on the fly and reached more than a million users within days of its public release. Decart's second model, Mirage, can transform and re-imagine arbitrary input video in real time, demonstrated publicly to wide attention from figures including Mark Zuckerberg and Elon Musk.
Underneath the consumer demos, Decart's edge is a tightly engineered GPU optimization stack that drives the cost of diffusion-based video generation from hundreds of dollars per hour down to under 25 cents per hour, which is what makes interactive frame-rate generation economically viable.
Who it's for
Decart targets creators, gaming and entertainment platforms, social apps, and developers who want to build live video experiences instead of pre-rendered clips. The company has positioned itself as a long-term challenger to Netflix-, YouTube-, and TikTok-style passive video, betting on real-time interactive AI video as a new format.
Pricing
Decart's consumer apps for Oasis and Mirage are usage-based with a free entry tier. Enterprise and developer pricing is custom-quoted around inference volume on Decart's optimized GPU stack.
Team & funding
Decart was founded by Dean Leitersdorf (co-founder & CEO, Technion CS PhD with a focus on distributed computing and GPU optimization) and Moshe Shalev (co-founder & CPO, Israeli Defense Forces 8200 unit veteran). The company is headquartered in Tel Aviv. Decart has raised approximately $153M in cumulative funding, including a $32M round in late 2024 and a $100M Series B in August 2025 at a $3.1B valuation, led by Sequoia Capital with Benchmark, Zeev Ventures, and Aleph VC participating. Notably, Decart reports having spent under $10M of its capital while generating revenue from GPU acceleration and licensed video — a striking capital efficiency profile for the category.
