About

Zenithon AI develops machine learning world models to accelerate simulations in fusion energy, rocketry, and semiconductor manufacturing. The London-based startup aims to test one million engineering designs in the time it previously took to run a single simulation. Founded by Alex Higginbottom and plasma physicist Abetharan Antony, the company trains large foundation models on proprietary simulation and real-world data. Their technology serves as a substitute for conventional simulation software, enabling engineers to evaluate more design options with uncertainty estimates.
