What Wind Fisher does
Wind Fisher is a French deep-tech startup founded in 2021 and headquartered in Grenoble, with team presence in Paris. It develops Magnus-effect airborne wind energy systems under the product family 'Magnus Airborne Generator' (MAG), comprising a helium-filled cylindrical wing tethered to a ground station and operated at approximately 300 m altitude, where wind is materially stronger and steadier than at conventional turbine height. The wing spins at ~300 rpm to generate Magnus force; tethers transmit that force to ground-station winches, each equipped with a 2 kW generator, producing electricity without a tower, blades, or concrete foundation. The company holds two granted patents covering the tethered spinning airborne wing and a pending application on the MAG architecture, and is pursuing EASA certification as a Tethered Gas Balloon (CS31-TGB), with three of four criteria already validated.
The commercial product portfolio consists of MAG25 (100 kW containerized unit targeting remote/off-grid sites at a target LCOE of 90–110 EUR/MWh and 3–5x cheaper than diesel) and MAG80 (2 MW unit targeting utility-scale 10–100 MW wind farms at a target LCOE of 32–50 EUR/MWh and a 60% load factor). Validation has progressed through the MAG15 prototype, which completed its first autonomous 15-minute flight in August 2025 at the Transpolis testing facility; a pilot with Montenegro's national energy company EPCG is planned for 2026 and commercial launches of MAG25 in 2026 and MAG80 in 2027. Go-to-market combines direct enterprise sales to utilities, mining, telecom, agriculture, and military off-grid customers, supplemented by equity crowdfunding via Sowefund; the company reports 15 LOIs representing 180M EUR in potential revenue and is currently pre-revenue. Capital sources to date include a 100k EUR BPI France seed loan, French Programme d'Investissements d'Avenir funding, and participation in the Techstars Sustainability Paris accelerator.

Wind Fisher product offering
Product offeringCore offering
Wind Fisher designs, manufactures and sells Magnus Airborne Generator (MAG) systems — helium-filled lighter-than-air cylindrical wings that operate at 300–500m altitude and convert the Magnus effect into electricity via ground-station winches. Its commercial lineup includes the MAG25 (100 kW, containerized for remote/off-grid sites) and the MAG80 (2 MW units grouped into 10–100 MW wind farms for utility-scale deployment), with a MAG15 prototype used for validation testing.
Product overview
Wind Fisher develops Magnus Airborne Generators (MAG), an airborne wind energy system that uses helium-filled cylindrical wings to capture high-altitude wind (300m) and convert the Magnus effect into electricity. The product portfolio consists of two commercial models: MAG25 (100 kW unit for remote sites and small industries) and MAG80 (2 MW unit for utility-scale grid integration). Both products share the same core technology principles: high-altitude wind capture, Magnus effect force generation, and lighter-than-air design for autonomous operation. The MAG15 prototype was used for validation and testing.

Wind Fisher competitors and assessment
Company assessmentBroad incumbents
- GE Renewable Energy: Global wind OEM with onshore and offshore product lines, plus grid integration services. Competes with Wind Fisher's MAG80 in the utility-scale segment and represents a potential channel for utility-scale adoption if partnership structures emerge.
- Shell (Makani): Energy major that acquired Makani (formerly Google X's airborne wind project) in 2020. Represents the largest balance sheet committed to AWE and is a broad incumbent competitor in the category, though Makani's specific program status has been ambiguous.
- Siemens Gamesa Renewable Energy: Major wind turbine OEM and offshore wind developer. Incumbent in Wind Fisher's target utility-scale segment, with R&D capabilities that could pivot into AWE if the technology proves commercially viable.
- Vestas: Global leader in traditional wind turbine manufacturing. Represents the incumbent competitive benchmark Wind Fisher must displace in utility-scale, and a potential future strategic acquirer or partner if AWE matures into a complementary product line.
- Enercon: German-based wind turbine manufacturer with strong presence in European markets. Direct incumbent competitor in Wind Fisher's home European utility segment, with deep relationships across German and European utility customers.
Direct peers
- Kitemill: Norwegian ground-based kite wind energy startup targeting utility-scale and distributed generation. Comparable as an AWE direct competitor pursuing ground-generation architecture with tethered flight.
- SkySails: German company developing tethered kite-based wind energy systems, originally for ship propulsion and now for utility-scale power. Comparable in airborne wind category and pursuit of utility customers, though using traction-kite architecture rather than Magnus-effect wings.
- Kitepower: Dutch developer of ground-based kite wind energy systems targeting off-grid and remote applications. Closest direct peer to Wind Fisher in deployment model (containerized ground station generating from tethered flight) and customer focus (diesel replacement).
- TwingTec: Swiss startup developing tethered drone-based airborne wind energy systems with ground-level power conversion. Direct competitor in the AWE category, with comparable focus on scaling tethered-flight technology to commercial maturity.
Emerging players
- Altaeros Energies: US-based developer of tethered aerostat systems that lift conventional turbines to high altitudes for remote and off-grid applications. Competes in the same high-altitude wind category but uses a fundamentally different (aerostat-mounted turbine) architecture.
