Arondite is a London-based defence technology company founded in 2023 by Will Blyth and Rob Underhill. The company builds foundational AI software and mission orchestration platforms designed to integrate autonomous systems, sensors, and robots for defence operations. Blyth served 12 years in the British Army before working at Palantir and Helsing; Underhill was a lead engineer at BAE Systems and a founding engineer at Garrison Technology.
Its core product, Cobalt, is an AI-powered mission orchestration platform that connects disparate autonomous systems, sensors, and effectors from different manufacturers into a unified operating picture. Human operators can oversee and control multiple autonomous assets through a single interface while retaining authority over critical decisions. The platform is designed to be vendor-agnostic, functioning as connective tissue between systems regardless of their origin.
Arondite has raised over $12 million in funding, with Index Ventures and Concept Ventures among its investors. The company holds a multi-million pound contract to work with the British Army's Global Response Force on next-generation mission orchestration. It carries ISO 9001 Quality Management certification and UK NCSC Cyber Essentials Plus certification.
