London-based space technology company Spaceflux has raised £5.4m in seed funding to expand its global network of optical sensors.
The firm, which was founded just three years ago, will also use the investment to accelerate the development of its AI-powered platform for tracking satellites and space debris.
The round was co-led by the UK Innovation & Science Seed Fund (UKI2S), Foresight Group and Blackfinch Ventures, with the startup now responding to growing demand for sovereign and commercial space surveillance capabilities.
Spaceflux combines visible and short-wave infrared imaging to deliver 24/7 tracking, allowing satellites and debris to be monitored during both day and night – an industry first.
The raise comes at a time of increasing concern over the safety and sustainability of space operations, with a recent UK Government report warning that a one-week disruption to satellite navigation could cost the UK economy £7.6bn.
The organisation’s technology aims to mitigate such risks by helping governments and businesses better understand and manage the increasingly crowded orbital environment.

“As space becomes increasingly essential to our economy, environment and daily lives, it is also becoming more congested and contested,” said Spaceflux CEO and co-founder, Marco Rocchetto.
“This investment strengthens our ability to protect satellite technology that delivers crucial insights to Earth around the clock, reducing collision risks, and supporting a safer, more sustainable space environment for future generations.”
The company’s analytics platform, Cortex, uses AI to process vast amounts of sensor data to help satellite operators, insurers and defence agencies make real-time decisions about the movement and safety of space assets.
The new capital will also be used to expand the global sensor network, upgrade Cortex and grow the company’s commercial reach.
Alex Leigh, investment director for defence & security at UKI2S, added: “This investment marks a significant step in the convergence of defence and space, where dual-use technologies are becoming increasingly important to UK capability.
“Backed by both the UK Space Agency and MOD, we are delighted to be leading this round as it underlines the growing importance of resilient, space-based infrastructure.
“Spaceflux’s technology offers critical insights to help monitor and safeguard orbital assets – supporting both national security and the wider commercial ecosystem.
“The company is well positioned to scale its impact and meet the needs of customers navigating an increasingly complex space environment.”
