MBM Commercial advises CSignum on £2.6 million funding round to accelerate underwater and through-ground monitoring of critical infrastructure
MBM Commercial has advised CSignum, a leading provider of wireless communications from beneath the surface of water, ice and ground, on a successful £2.6 million funding round to accelerate commercial deployment of its EM2 product portfolio across multiple markets and applications, including water quality monitoring.
The investment supports CSignum’s mission to become an indispensable enabler of AI in the physical world, extending reliable data communications to underwater and below ground environments that have historically been impossible to connect.
Archangels, PXN Ventures, Scottish Enterprise, British Business Bank and a group of US-based angel investors have provided additional investment, reflecting their continued confidence in CSignum's technology and momentum in multiple markets.
MBM Commercial’s corporate team, led by Alexander Lamley, advised Csignum throughout the investment transaction.
Alexander Lamley, Partner at MBM Commercial, said:
"We are delighted to have supported CSignum on this latest funding round. The continued backing from existing investors, alongside new investment into the business, is a strong endorsement of both the technology and the team's commercial achievements. CSignum is operating in a rapidly growing market and this investment places the company in a strong position for its next phase of growth. We look forward to seeing the business continue to scale in the UK and internationally."
Founded in 2020, CSignum is headquartered in Bathgate near Edinburgh and continues to add staff in the UK, USA and EU as it scales its operations.
The latest funding round will be used to support commercial expansion and manufacturing scale-up. Since completing a £6 million investment with the existing investor group in April 2025, CSignum has moved from pilot projects into volume deployments with multiple UK water utilities and international customers.
CSignum also confirms that John Nicholls has been appointed as the Chief Executive Officer, succeeding Jonathan Reeves, a successful US-based technology entrepreneur. Jon will transition to the role of Chief Strategy Officer. Nicholls brings broad experience as both CEO and Chief Commercial Officer in international sales growth, fundraising, M&A and strategic partnerships across a wide range of market sectors including photonics, quantum technologies, space, semiconductors and EV infrastructure.
John Nicholls, CEO of CSignum said:
"I’m excited to be joining CSignum at this pivotal moment in its journey. The team has built a differentiated technology and strong customer relationships across diverse market sectors, and my focus now is turning that potential into large-scale deployments. More broadly, CSignum exists to close the communications gap between inaccessible parts of the physical world and the digital and AI systems that increasingly depend on them. This investment lets us do exactly that, faster."
Congratulations to John Nicholls and the entire CSignum team on securing this significant investment. We look forward to following the company’s continued growth and success.
