Symetrica, a Southampton, UK-based global leader in radiation detection and identification, secured further £3m in growth funding.
The round, which brought total funding raised to date to £10m, was co-led by Parkwalk and Nesta with participation from Albion Investments, Technology Venture Partners and Tennants Ventures.
The company intends to use the funds to expand US presence and open a larger US manufacturing site in Westford, Massachusetts later this summer.
Founded by the former head of Physics and Astrophysics at Southampton University in 2002 and led by Heddwyn Davies, Chief Executive Officer, Symetrica provides a range of detectors from handheld devices to mobile solutions and portal monitors, which are used by customs and border protection, law enforcement and military, emergency services and first responders around the world.
Its technology is currently used by EU Policing and Customs Authorities and the US Department of Homeland Security, amongst others.
The company now has offices and manufacturing sites in the UK and the US, employing 75 people.
