Arondite

The founders' backgrounds directly inform the company's mission. Blyth is a former British Army officer with subsequent roles at Palantir and the AI defense firm Helsing, providing frontline operational insight. Underhill contributes deep technical expertise as a former lead engineer at BAE Systems and the founding engineer at Garrison Technology. Blyth's experiences on the battlefield, where the lack of interoperability between systems posed significant risks, were a direct inspiration for Arondite.

The company's Cobalt platform is hardware-agnostic and serves clients in the defense, critical infrastructure, and security sectors. It functions as a data engine, using machine learning to process inputs and generate real-time analytics for operators, thereby improving decision-making and efficiency. Early applications of the technology include minefield clearance and counter-intrusion for protecting large-scale infrastructure. By focusing on software integration rather than building new hardware, Arondite differentiates itself from competitors. In May 2025, the company announced it had raised over $12 million in total funding, including a $10 million Seed round led by Index Ventures and a prior $2.25 million pre-seed round, to expand its engineering teams and advance its AI models.
