A start-up that uses digital fingerprinting to secure devices and helps government customers adopt new technology.

About Rowden Technologies

Rowden Technologies builds the technology that helps soldiers and emergency teams in places where phones, radios and the internet do not work reliably. It designs, builds and deploys hardware, software and systems for demanding "disconnected" environments, mainly for defence and national resilience. Its tagline is "Reliable solutions for unreliable environments", and it makes sensing, communications and computing systems that still work when power, bandwidth and computing capacity are limited.

Rowden says it is a UK-headquartered industrial technology company, and a business database gives its founding year as 2016. Its registered address is in Bristol, and the website lists offices in Bristol and in Paddington, London. The site links to a founder blog by Rob Harper but does not describe leadership, and we did not confirm who founded it. It was included in the FT1000 list of Europe's fastest-growing companies and was part of the NCSC for Startups programme run by Plexal.

Rowden's stated aim is to make complex technology work where resources are limited, delivering better operational safety, faster decision-making and quicker delivery of capability for defence and national resilience. A trade report describes its way of working as putting outcomes ahead of effort, with soldiers (operators) working alongside engineers and product owners to shorten feedback loops.

Its best-known product is the Dismounted Data System (DDS), which it designed and which is used by British Army soldiers on foot; it is a mission partner delivering this through an Army programme called ASGARD. Its work also covers machine learning at the edge (running AI on small devices rather than in a data centre) and radio-frequency challenges, and it has shown a decoy system called Mimic. In 2026 it hosted Army Sergeant Majors in a development programme with the Allied Rapid Reaction Corps.

Rowden recruits early-career people. Its Graduate Engineering Programme for a September 2026 start was based in Bristol, paying £31,500 a year (as at 2026). It asked for a STEM degree or equivalent experience and eligibility for SC security clearance, though it welcomed transferable skills. Graduates rotate through areas such as software, machine learning, systems, safety, radio-frequency and infrastructure engineering, then choose a focus. The process was a timed technical test, a call and an assessment day. That round is now closed, and a 2027 register-your-interest page was listed. These programme details are the company's own.
