CSignum, an Edinburgh, Scotland, UK-based provider of wireless technology extending IoT communications beneath the surface, raised £6M in Series A funding.
The funding round was led by Archangels, Par Equity, and Scottish Enterprise with participation from British Business Investment (BBI), Raptor Group, Deep Future, SeaAhead’s Blue Angel Network, and individual US investors.
The company intends to use the funds to expand its global presence, accelerate product development and address the demand for real-time data transmission for underwater and underground applications.
Led by CEO Jonathan Reeves, CSignum provides EM-2 solutions with wireless communication technology, transmitting data via patented electromagnetic field signalling (EMFS), through environments including water, ice, soil, rock and concrete to networks above the surface. Key applications for EM-2 systems include water quality and environmental monitoring, wireless under-ship monitoring, and security applications for underwater infrastructure such as offshore wind turbines and oil and gas platforms.
The company also offers CSignum Cloud, providing data services to complement its wireless systems.
