Origins

Decart was founded in 2023 in Tel Aviv by Dean Leitersdorf and Moshe Shalev, with a founding thesis explicitly oriented around real-time generative video and interactive world-model applications. The company emerged in stealth through 2023 to early 2024 with a focus on the technical infrastructure for real-time generative-video applications.

The October 2024 unveiling of Oasis (a real-time interactive Minecraft-equivalent world simulation) was the company's most consequential public-facing milestone. Oasis demonstrated real-time generation of an interactive world simulation at frame rates approaching playable game performance, with industry attention as a technical demonstration of the real-time generative-video direction.

The October 2024 Series A of $32 million led by Sequoia Capital and Zeev Ventures, with additional Adam Neumann personal investment and other participants, anchored commercial-development resources for continued real-time interactive world-model research and product expansion.

The 2024 to 2026 period has continued real-time interactive world-model research and commercial-product expansion.

Mission and strategy

Decart's stated mission is to advance real-time generative video and interactive world-model technology. The strategic premise reflects 2024 to 2026 commercial interest in interactive world models, with Decart explicitly positioning itself as a frontier real-time interactive world-model company.

The strategy has two threads. First, real-time generative-video research with Oasis-line demonstrations. Second, continued commercial-product expansion across interactive world-model applications including gaming, entertainment, and other application domains.

The competitive premise reflects Decart's distinct positioning combining Israeli founder-team technical credibility with the real-time interactive world-model market opportunity.

Distribution channels include the Oasis web interface, planned commercial-product expansion, and industry attention through the October 2024 Oasis demonstration.
