About Zenithon AI
Zenithon AI is a UK-based software startup developing foundational machine learning models to accelerate complex physics simulations. The company's primary focus is on advancing nuclear fusion research by drastically reducing plasma simulation times from months to seconds. This capability aims to enable faster and more intelligent design processes within the energy and engineering sectors.
The company was founded in 2025 by CEO Alex Higginbottom, who left his ML PhD to establish the firm, and Co-founder & CTPO Abetharan Antony, who holds a PhD in Plasma Physics. The founding team combines expertise in physics and AI to address significant simulation bottlenecks in the industry. Zenithon AI's models are designed to be physics-grounded, provide uncertainty estimates, and integrate into existing workflows and tools.
Zenithon AI operates on a B2B model, partnering with teams that manage mission-critical physical systems in need of advanced AI tools for simulation, control, and research. The startup participated in the SPARK 1.0 incubator, a program created by King's Entrepreneurship Lab in partnership with Founders at the University of Cambridge, designed to help validate and launch early-stage ventures. As of August 2025, the company had raised $136K in funding from investors including King's Entrepreneurship Lab and Unruly Capital.
