CSignum develops patented EM-2 systems that use electromagnetic field signaling (EMFS) to wirelessly transmit data through challenging environments such as water, ice, soil, rock and concrete to surface networks. Its core offerings include EM-2 hardware and CSignum Cloud, a dashboard and analytics platform already deployed on several river water quality monitoring projects. Key applications include water quality and environmental monitoring, wireless under-ship monitoring, and security for critical underwater infrastructure such as offshore wind turbines and oil and gas platforms. Founded in 2020, the company is working with customers in the UK, EU and US to address regulatory-driven demand for real-time monitoring. Upcoming compliance deadlines, including AMP8 real-time monitoring mandates, present a significant growth opportunity for its wireless solutions. The company plans to use the funding to expand its engineering team, advance its product portfolio and strengthen its market presence.
