Luxembourg-based startup TerraSpark has raised over €5 million in pre-seed funding, co-led by Paris-based VC daphni and tech investor Sake Bosch, to beam clean energy from orbit to anywhere on Earth, sending power “orbit by orbit.”
better ventures, the Hans(wo)men Group, the Luxembourg Business Angel Network, and Karaoke Club also joined the round.
The 2025 blackouts in Spain and Portugal made the problem hard to ignore: ageing grids, overloaded lines, and electricity demand that keeps climbing. A lot of that new demand is coming from data centres. The IEA expects their energy consumption to more than double by 2030, largely due to AI.
The harder question is how to get clean energy where it’s needed. In off-grid areas powered by diesel generators, electricity costs between €0.70 and €1.50 per kilowatt-hour. Even regions with plenty of renewable energy face transmission bottlenecks. You can have all the solar in the world and still not be able to move it.
Going to orbit, skipping the grid
TerraSpark was founded in 2025 by Jasper Deprez (who built Tradler into a global HR tech platform for Amazon and ABB), Dr Sanjay Vijendran, and Matthias Laug (who co-founded Lieferando and Tier Mobility), to capture solar energy in orbit and transmit it back to Earth via radio frequency.
The idea of space-based solar power dates back to the 1970s. What’s changed is that launch costs have dropped, satellites are cheaper to build, and orbital robotics has caught up enough to make it worth trying seriously.
“The core technologies have existed since the 1970s. The real question is: can energy be delivered at a price customers are willing to pay? Key bottlenecks involve unit economics: efficiency, launch cost, in-space assembly and scalability, component lifetime and reliability, and manufacturing cost. The solution requires reducing all these costs simultaneously,” Deprez explains.
Rather than starting with a massive orbital system, TerraSpark is proving the technology on the ground first, commercialising RF-based wireless energy transmission for industrial applications before moving into space. It’s a more patient approach than most space energy plays, and it shapes everything about the company’s architecture.
“Most older space-based solar power ideas ask: what’s the maximum power we can beam at the lowest theoretical cost? That usually means big, centralised GEO systems. We ask: what’s the smallest commercially viable system we can build? That leads us to a LEO-based, modular, Starlink-like design focused on quick iteration, scalability, and early deployment,” Deprez adds.
While competitors in the space, including UK-based Space Solar and US-based Virtus Solis, are pursuing large-scale, centralised systems, TerraSpark is taking a modular, lower-cost, Earth-first model built around teams that have actually scaled companies before.
What comes next?
Within 12 months, TerraSpark aims to achieve 2–4 kW of wireless power transmission over 100 metres or more at 20–30% DC-to-DC efficiency, along with point-to-point power transmission within an orbiting satellite.
“TerraSpark has assembled a team that is hard to ignore. Space-based solar power is an ambitious challenge, and there is still a lot of important work ahead of us. What convinced us is the combination of in-depth technical expertise and proven implementation skills. We believe that this team offers Europe the best chance yet to make space-based solar power a reality,” says Sofia Dahoune, partner of daphni.
“This mix of technical depth and implementation power is exactly what Europe needs for resilient energy infrastructure,” adds Tina Dreimann, founder and managing director of better ventures.
