CSignum, a Scottish provider of wireless technology extending IoT communications underground and underwater, has completed a £6m series A funding round.

The investment should accelerate growth of its EM-2 family of products, which are transforming the way critical wireless sensor data is transmitted from submerged environments to networks above. It should also let the company expand its global presence, accelerate product development and address the growing demand for reliable, real-time data transmission for underwater and underground applications.

CSignum’s EM-2 products (www.csignum.com/em2) represent a breakthrough in wireless communication technology, capable of reliably transmitting data, via patented electromagnetic field signalling (EMFS), through environments including water, ice, soil, rock and concrete to networks above the surface. Key applications include water quality and environmental monitoring, wireless under-ship monitoring, and security applications for critical 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. The company’s dashboard and analytics have been deployed on several river water quality monitoring projects.

CSignum is working with customers in the UK, EU and USA to address growing environmental regulatory requirements. With upcoming deadlines for compliance, including large-scale real-time monitoring mandates under the AMP8 initiatives, the demand for innovative, wireless options presents a growth opportunity for CSignum and its EM-2 technology.

“This investment reflects the growing recognition of the critical need for innovative communications in the underwater IoT sector,” said Jonathan Reeves CEO at CSignum. “The support from our investors will allow us to scale our operations, enhance our product offerings and help industries worldwide manage their resources more effectively. We are grateful for their trust and excited to shape the future of underwater communication.”

The funding round was led by Archangels, Par Equity and Scottish Enterprise with additional investment from British Business Investment (BBI), Raptor Group, Deep Future, SeaAhead’s Blue Angel Network and individual US investors.

“CSignum has developed a truly unique technological breakthrough which could be a game-changer for those industries reliant on securing reliable data from their underwater operations,” said Dan McKiddie, investment manager at Archangels (archangelsonline.com). “We’re looking forward to supporting the management team in their efforts to scale the business and disrupt the global market for underwater communication.”

Claire Clamm, investment manager at Par Equity (www.parequity.com), added: “CSignum’s ability to deliver reliable and cost-effective communications for challenging environments sets them apart in the market. This funding will accelerate their journey to becoming a global leader in underwater data transmission. We are excited to partner with them as they expand their reach and capabilities.”

Founded in 2020, CSignum (csignum.com) is headquartered in Bathgate near Edinburgh, and plans to add additional staff in the UK, USA and EU over the next year as it continues to scale its operations.
