What TerraSpark does

TerraSpark is a Luxembourg-headquartered space-based solar power (SBSP) startup founded in 2025, developing radio-frequency (RF) wireless power transmission technology — operating at 5.8 GHz — designed to beam solar energy collected in orbit to ground-based receivers. The company is building a modular satellite architecture intended to scale into a constellation, with a 2027 in-orbit demonstration planned aboard Dcubed's ARAQYS-D3 mission and a stated commercial deployment target of 2030.

The company pursues a B2B/B2G infrastructure model, targeting six end-market verticals: islands and microgrids, critical infrastructure, mining operations, defense, data centers, and desalination facilities. Customer economics would derive from long-duration power purchase agreements (PPAs) or direct infrastructure leases delivering baseload or supplementary energy to off-grid or energy-constrained users. An MOU with EDGX signals exploration of bundled orbital-power-plus-edge-compute offerings, which could broaden the revenue model beyond pure energy delivery. The company is pre-revenue, with no disclosed pilots or offtake agreements as of the data available.

TerraSpark is led by a three-person founding team: Jasper Deprez (CEO), Dr. Sanjay Vijendran (CTO, previously the lead of the European Space Agency's Solaris SBSP program), and Matthias Laug (COO, previously operations leadership at Lieferando and Tier Mobility). The combination pairs rare institutional SBSP technical expertise with operational scaling experience from venture-backed mobility platforms. Headcount stands at 11-50 employees with ~12 open roles, suggesting active expansion. The company has raised approximately €5 million in a pre-seed round co-led by Daphni and Sake Bosch, closed in early 2026.

Revenue model

1. Space-Based Power Transmission Services: TerraSpark plans to generate revenue by delivering continuous, weather-independent solar power from orbit directly to customers. Initial revenue will come from Earth-based wireless power transmission pilots and demonstrations for industrial applications, followed by orbital power delivery services to paying customers with fragile grids or high energy costs (remote islands, data centers, defense installations, mining operations, critical infrastructure). The modular constellation approach allows incremental capacity scaling matched to revenue growth.
2. Wireless Power Transmission Licensing: As the technology matures, TerraSpark may offer wireless power transmission systems and associated IP for industrial and commercial applications on Earth, potentially licensing technology components and operational expertise.

Core offering

TerraSpark develops space-based solar power (SBSP) infrastructure comprising modular orbital satellites that capture solar energy 24/7, radio frequency (5.8 GHz) wireless power transmission systems that beam the energy to Earth through a steerable, precision-tracked beam, and ground-based rectenna receiving stations that convert the radio waves into grid-ready electricity. The integrated system is designed to deliver continuous, weather-independent baseload power to remote, off-grid, and critical infrastructure customers worldwide.

Product overview

TerraSpark is a Luxembourg-based European startup developing space-based solar power technology using a modular approach. The company offers a unified system comprising three integrated components: (1) Space-Based Solar Power Satellites that capture solar energy in orbit, (2) Radio Frequency Wireless Power Transmission systems operating at 5.8 GHz to beam energy safely to Earth, and (3) Rectenna Ground Receiving Systems that convert radio waves into grid-ready electricity. TerraSpark follows a phased development roadmap: demonstrating wireless power transmission on Earth (2026), launching an orbital technology demonstrator via the Dcubed ARAQYS-D3 mission (2027), achieving first space-to-Earth power transmission (2028), and targeting full commercial deployment (2030).

Products and services

• Space-Based Solar Power Satellites Modular, lightweight satellites positioned in Earth orbit that capture solar energy continuously (24/7) without weather or day-night dependencies and transmit the captured energy to Earth via radio frequency wireless beams. Designed for incremental deployment, autonomous operations, mass production, and in-orbit technology updates.
• Radio Frequency Wireless Power Transmission System Proprietary wireless energy transmission technology using radio frequency at 5.8 GHz to safely beam power from orbit to Earth through a steerable, precision-tracked beam. Uses the same spectrum as WiFi and satellite communications, with ground power density designed at approximately 250 W/m² — lower than natural sunlight — and beam safety interlocks for automatic shutoff on misalignment. A potential standalone offering for industrial wireless power applications.
• Rectenna Ground Receiving Systems Ground-based receiving antennas (rectennas) that convert transmitted radio waves into electrical power for grid distribution. Designed to deliver higher energy density per square meter than terrestrial solar farms on a continuous basis. Each receiver incorporates 40 RF-DC converters, each capable of lighting multiple LEDs. Compatible with dual-use of land (agriculture, ground solar/wind, blended ecosystems).

Partnerships

Four partnerships are on record, tiered minor and core.

• EDGXminorStrategic or Co-development Partner · 22 June 2026TerraSpark and EDGX signed a Memorandum of Understanding to explore integrating EDGX's AI compute hardware with TerraSpark's space-based solar power satellite architecture. The partnership explores whether surplus energy on SBSP satellites (when not transmitting to Earth) could run useful compute workloads. Initial collaboration focuses on assessing whether thermal management challenges overlap in ways that allow joint R&D to accelerate both parties' technical roadmaps.
• DcubedcoreStrategic or Co-development Partner · 29 March 2026TerraSpark is one of five mission partners in Dcubed's ARAQYS-D3 mission, which will demonstrate in-space power generation and transmission capabilities. TerraSpark will demonstrate radio frequency-based wireless power transmission in space by sending power from a shoebox-sized transmitter to a laptop-sized receiver across the host spacecraft. The mission is planned for launch with SpaceX as early as February 2027, with the satellite platform provided by Astro Digital. This represents TerraSpark's first orbital demonstration and a critical milestone toward commercial deployment.

Direct peers

• Star Catcher Industries: US startup developing space-to-space wireless power beaming infrastructure to sell 'energy as a service' to other satellites in orbit. Closely comparable technology category (wireless power beaming from orbit) and overlapping customer base, with a complementary near-term focus on satellite customers rather than terrestrial.
• Aetherflux: US-based space-based solar power startup founded by Baiju Bhatt (Robinhood co-founder), pursuing an LEO constellation to beam solar energy to Earth. Most direct US competitor to TerraSpark in commercial SBSP, with a different (laser/photovoltaic) technical approach but the same end market.
• ORiS: European (Italian) space-based solar power startup that is also a mission partner on the same Dcubed ARAQYS-D3 flight as TerraSpark. Direct peer demonstrating competing space-to-Earth power transmission on shared launch infrastructure, validating the broader commercial SBSP thesis.
• PowerLight Technologies: US-based pioneer in long-range laser power beaming (formerly LaserMotive), demonstrating wireless power delivery for drones, spacecraft, and terrestrial applications. Direct peer in wireless power transmission technology with relevant intellectual property and a longer operational track record.
• Volta Space Technologies: US/Canadian company developing optical (laser) wireless power beaming from space, also a Dcubed ARAQYS-D3 mission partner. Direct peer pursuing the same wireless orbital power market via an alternative (optical rather than RF) transmission modality.

Emerging players

• Astrostrom: European SBSP concept-stage company developing lunar-orbit-based solar power concepts (Greater Earth Lunar Power Station). Niche peer in space-based solar with a longer-term, lunar-orbit focus and overlapping thought-leadership in the European SBSP ecosystem.
• Reflect Orbital: US startup deploying a satellite constellation of sunlight reflectors to extend daylight to solar farms after sunset. Adjacent space-to-Earth energy delivery concept — same orbital infrastructure thesis but exploits reflected sunlight rather than generated/transmitted power, with simpler economics.

Broad incumbents

• Astro Digital: US satellite bus provider supplying the platform for the Dcubed ARAQYS-D3 mission on which TerraSpark's RF payload flies. Adjacent space-infrastructure incumbent rather than a competitor — but a comparable scale-stage space hardware company and useful reference for satellite manufacturing economics.
• Dcubed: German deployable space structures company hosting the ARAQYS-D3 multi-partner mission in which TerraSpark demonstrates its technology. Indirect strategic enabler rather than direct competitor, but central to TerraSpark's orbital validation roadmap and a credible comparable in European deep-tech space hardware.

Others

• EDGX: Belgian space AI-compute hardware startup that signed an MOU with TerraSpark to explore in-orbit compute workloads running on surplus SBSP satellite energy. Ecosystem participant rather than competitor — represents the broader category of in-orbit compute and energy-consuming space applications adjacent to SBSP.
