Helix Geospace raises £3m in seed funding led by Bloc Ventures to scale production
The seed round was led by Bloc Ventures with participation from UKI2S and private backers.
Helix Geospace develops specialised antennas and electronic systems that protect navigation and timing services from interference and malicious attacks. The firm serves customers across the automotive, aerospace, defence, and critical infrastructure sectors.
Helix Geospace has secured £3m in seed funding to transition its advanced antenna technology into mass production. The round was led by Bloc Ventures, with participation from the UK Innovation and Science Seed Fund and private investors.
The capital will support the company as it scales manufacturing operations to meet growing international demand from the automotive, aerospace, defence, and critical infrastructure sectors. Helix produces precision antennas designed to withstand signal jamming and environmental interference.
The latest injection of capital follows £2.5m in prior backing from public and private sources, alongside various accelerator programmes and development grants.
From the founder
"We started manufacturing DielectriX antennas using state of the art laser/robotics equipment developed in-house, and we are now set to scale up rapidly through partnerships with electronics manufacturing service providers in the UK. Future manufacturing growth plans will roll out our 'factory-in-a-box' to deliver global capability required to meet the expected demands for autonomous vehicles and systems where absolute resilience and precision of location data is essential for safety."
James Lewis
CEO at Helix Geospace
Investor perspective
"Over 10 billion devices make use of satellite GNSS signals for geolocation, from simple consumer location services to critical aerospace applications. But the challenge of reliable, resilient location in demanding environments remains the same. Helix has gone to the root of the problem, the antenna, with a design made possible by the company’s world leading advances in AI, applied to advanced 3D manufacturing of ceramics. The result is the highest signal sensitivity from the smallest physical size, and the lowest implementation complexity and cost for a GNSS receiver. We’re really excited to support the team as they begin scaling the company and developing the product alongside their initial customers."
