Ownership
Founder-built. Investor-owned.
Simon von Rothschild built Bastion from a 2019 start-up into a multi-domain defense manufacturer—platforms, powertrains, radars, C-UAS, artillery, high-security vehicles, and specialised ambulances. In 2024 he sold the company to investors and stayed on as CEO only, reporting to the board.
