Decart AI Ltd. is an Israeli artificial intelligence startup and research lab focused on developing real-time models for image, video, audio, and multi-model. The company is engaged in expanding the boundaries of interactive artificial intelligence, with an emphasis on transforming live content into dynamic media. [1]

Decart is known for developments such as Oasis – an interactive game in which worlds are created in real time using AI, and Live-Stream Diffusion (LSD) – a family of real-time video creation models that enables continuous, interactive, and live processing of video.

history

The company was founded in September 2023 by Dean Leitersdorf (CEO) and Moshe Shalev (VP of Product), both alumni of Unit 8200. [2] 

Moshe Shalev was born in 1987 and raised in an ultra-Orthodox Jewish family in Bnei Brak . He enlisted in the IDF at the age of 23, where he served in the Intelligence Division for about 13 years, most of them in command positions. During his service, he was a co-founder of the IDF's Artificial Intelligence Research Department. In 2017, together with his unitmate Dor Saban, he founded the Start-Ach non-profit organization, which works to develop technological solutions for non-profit organizations in Israel. 

Dean Leitersdorf grew up between Israel, Switzerland, and Silicon Valley. He completed his PhD in Computer Science at the Technion at the age of 23, and then completed a postdoctoral fellowship at the National University of Singapore . In 2023, he won the ACM PODC Dissertation Award for the world's best PhD in distributed computing. He has also won three awards for outstanding student papers at the PODC conference.

As early as late 2023, Decart developed GPU optimization technology, which allowed the company to sign initial contracts with cloud computing providers and achieve early profitability.

In October 2024, Decart left Stealth, an international network for early-stage entrepreneurs, and launched Oasis in partnership with Etched. Oasis is an interactive game where the world is built in real time using a generative video model. The game gained over a million users in just three days and received widespread international exposure.[3]

Immediately after the model was launched, Elon Musk tweeted his admiration for the technological achievement, which helped expand international coverage of Decart. [4]

In July 2025, Decart announced a collaboration with the Technion to establish a joint research center and the Descartes Excellence Program, with the aim of advancing the field of AI research in Israel.[5]

During 2025, Decart opened additional branches in San Francisco and New York. As of summer 2025, the company employs over 60 people. [6] [7]

Capital raising

Since its inception, Decart has raised $153 million in three major rounds within 11 months:

  • October 2024 – Seed funding of $21 million led by Sequoia Capital and with the participation of other entities, including: Zeev Ventures (which took part in establishing the company in the pre-seed stage). [8] [9]
  • December 2024 – $32 million Series A led by Benchmark Capital, at a valuation of approximately half a billion dollars. [10][11][12]
  • August 2025 – Another $100 million round led by returning investors Benchmark Capital, Sequoia Capital[13] and Zeev Ventures, as well as Valley Capital Partners, Regah Ventures and Aliya Capital Partners. The funding was done at a valuation of $3.1 billion, making Descartes AI a unicorn.[14][15]

Despite the funding, the company reported that it spent less than $10 million of investor money, with computing costs (GPU) mostly covered by contractual revenue.

Products

  • GPU Optimization Stack – an internal infrastructure for optimizing GPU usage, which served as the basis for initial contracts with cloud providers.
  • Oasis – an interactive AI-based game where the world is constructed in real time based on the player’s actions. Launched in October 2024, it was the first large-scale implementation of a live generative video model. [16]
  • Mirage LSD – an autoregressive video-to-video model that produces real-time, infinite-length video, launched in July 2025. Allows any live video to be transformed into different visual styles while maintaining motion and frame rate stability. [17]

technology

Decart developed the Live-Stream Diffusion (LSD) architecture – a model for real-time continuous video production [18] .

Main principles [19] :

  • Casual autoregression – each frame is built on the previous frame and the textual command, ensuring a stable flow and visual continuity.
  • Dealing with error accumulation – the company introduced two mechanisms:
    • Diffusion Forcing – local error correction during training, to reduce deviations over time.
    • History Augmentation – Using frame history to stabilize the image and "erase" repeated errors.
  • Performance – The model reaches 24 frames per second at a resolution of 432×768 and a latency of less than 40 milliseconds. The company has stated its intention to expand support to Full HD and 4K.
  • Hardware efficiency – The system is written at a low CUDA level and optimized for advanced NVIDIA GPUs, reducing processing costs from $10–$1000 per hour to less than $0.25 per hour.

This technology enables real-time uses in the areas of gaming, streaming, advertising, and video calling, where immediate interactivity is required. [20]
