Space technology startup TerraSpark announced that it has raised €5.4 million (USD$6.2 million) in a pre-seed funding round, with proceeds aimed at advancing its space-based solar power technology to deliver continuous, weather-independent renewable energy from orbit.
Founded in 2025, Luxembourg-based TerraSpark is developing technology designed to capture solar energy in space and transmit it wirelessly to Earth via radio frequency, making power available regardless of the time of day or weather conditions, “orbit by orbit.”
According to the company, space-based solar energy could help to address key energy challenges – including increasing strain on energy infrastructure faces fragile grids, rising demand, and constrained transmission capacity – by providing constant solar power in orbit that is independent of weather conditions and globally accessible.
As a first step, TerraSpark said that it plans to launch on Earth with the commercialization of radio frequency-based wireless energy transmission for industrial applications, in order to demonstrate safety, efficiency, and regulatory compatibility, before scaling the system into orbit.
Jasper Deprez, founder and CEO of TerraSpark, said:
“Space-based solar power has long been considered something for the distant future. Across Europe, energy resilience is now a practical concern, not an abstract one. With our step-by-step approach and starting with commercially viable systems on Earth, we are convinced that space-based solar power can become real infrastructure within a realistic timeframe.”
The company said it plans to initiate initial pilot applications and demonstration use cases in the coming months, including wireless power supply for live events. The firm is also planning an orbital technology demonstrator by 2027, alongside the development of its first space-to-Earth power transmission system, targeted for 2028.
The financing round was led by Daphni, Sake Bosch, Better Ventures, the Hans(wo)men Group, the Luxembourg Business Angel Network, and Karaoke Club.
The company said that the financing will be used to further develop its technology and prepare for initial pilot applications and live tests.
Tina Dreimann, Founder and Managing Director of Better Ventures, said:
“TerraSpark combines European space expertise with the experience required to scale technology, a mix that is critical to building resilient energy infrastructure.”
