Background
Rob Harper MBE is the founder of Rowden Technologies, a Bristol-based defence-technology company he built from a military background to 160 staff working on sensing and information systems for edge environments. Harper's experience in the British Army shaped Rowden's customer orientation: the company's programmes include Human Machine Teaming, ASGARD, and the AUKUS AI for Acoustics initiative, with clients spanning the Ministry of Defence, British Army Cyber, Special Operations Command, and the Scottish Fire and Rescue Service.
On 13 May 2026, the National Wealth Fund invested £25m in Rowden Technologies — its first investment directly in defence, national security, and resilience. The £25m funds 100 new jobs within twelve months and 500 by 2032 across the Southwest and West Midlands. The NWF investment marks a milestone for UK sovereign capital's willingness to back defence capability alongside commercial innovation funds.
Harper's trajectory from serving officer to defence entrepreneur mirrors a broader UK push to translate military expertise into sovereign technology companies, particularly in the post-Integrated Review period when government policy has explicitly sought to commercialise dual-use capabilities.
