Decart AI

Decart AI develops world-model artificial intelligence that generates real-time interactive simulations and environments. The company's technology enables AI systems to understand and simulate complex physical environments, creating interactive experiences that respond dynamically to user inputs without pre-rendered content.

In February 2026, Calcalist reported that former Unit 8200 commander Yossi Sariel joined Decart, signaling the company's strategic pivot toward defense and intelligence applications. Sariel's appointment brings deep military AI expertise and connections to the Israeli defense establishment.

Decart raised a $21 million seed round from Sequoia Capital and Andreessen Horowitz (A16Z), representing significant Silicon Valley confidence in the company's world-model technology. This funding positions Decart among the best-capitalized Israeli AI startups at seed stage.

Defense applications of Decart's world-model AI include real-time battlefield simulation for military training, wargaming scenario generation, and digital twin creation for operational planning. The technology can simulate adversary behavior, terrain dynamics, and multi-domain operations without requiring expensive physical exercises.

The dual-use potential is substantial: commercial applications include gaming, virtual production, and interactive media, while military applications leverage the same world-model engine for training simulation, mission rehearsal, and intelligence analysis visualization.
