Emrys Systems Ltd, trading as Emrys, is a Plymouth-based deep technology company building the sovereign UK technology stack for defence, marine, aerospace and scientific applications — with three working prototypes and six whitepapers in development before raising a single pound of external investment.
To provide world-class technology. To develop the engineers, systems and ideas that keep the UK at the forefront of defence, marine and scientific innovation. To thrive as a British deep technology company built to last.
Most deep tech startups are founded by one technical person and one commercial person. Emrys has three engineers — and that's deliberate. The products Emrys is building require genuine depth across electronics, naval architecture, mechanical design, electrical systems and defence relationships. No single person could credibly claim all of it. This team can.
PhD in Electronics and Communication Systems Engineering, University of Plymouth. 15 years across maritime electronics, aerospace, RF and power systems. Built the Cyber-SHIP Lab at the University of Plymouth as lead engineer — X-Plex forms part of the Cyber-SHIP patent. Hands-on experience with small turbine engines and UAV systems gives Emrys in-house aerospace propulsion capability most deep tech startups have to hire in. Leads technology strategy, product development, IP and investor relations.
Naval Architecture and Mechanical Engineering. A decade inside UK defence procurement working on maritime and naval architecture programmes — institutional knowledge of MOD frameworks, language, relationships and timelines that most startups spend years learning from the outside. Naval architecture expertise applies directly to SonaSphere, Project Firkin and the wider maritime platform portfolio. Leads the defence relationship pipeline, prime contractor engagement and DASA grant strategy.
Mechanical and Electrical Engineering. 15 years at Princess Yachts designing complex, high-performance vessels from concept to build — with a focus on detailed electrical system architecture, mechanical design, and full vessel integration. His expertise is production-level: real systems, real constraints, real builds, in one of the most demanding marine environments in the world. That depth in mechanical and electrical design directly complements the founding team's electronics capability, giving Emrys an unusually complete hardware team at founding level. His Princess Yachts network provides Emrys with immediate warm access to the superyacht and commercial marine market.
Emrys's primary facility sits at Plymouth Science Park, Plymouth — purpose-built for marine and technology businesses, adjacent to Plymouth Marine Laboratory and within easy reach of HMNB Devonport, Princess Yachts, Babcock International and the University of Plymouth.
That proximity isn't incidental — it's the foundation for Emrys's go-to-market strategy across defence, marine and scientific ocean sensing all at once, and it's why the company is structured to engage classified defence work, public fabrication services and academic partnerships side by side, through appropriate physical separation and security protocols.
Emrys also operates an engineering consultancy from day one — end-to-end electronics, naval architecture, mechanical and maritime electrical design services delivered by the founding team, bridging cash flow between grant cycles and product revenue.
