What Reblade does
Reblade is a Danish deep tech startup founded in 2020 that has developed a drone-based automated system for repairing leading edge erosion (LEE) on wind turbine blades. The core technology is a flying drone carrying a "miniaturized factory" with four attachable robotic modules (cleaning, grinding, leading edge protection coating, and custom modules) that performs the entire repair workflow — surface preparation through coating application — while the drone is landed on the blade. The system uses computer vision, sensors, and cloud-based software for navigation, blade landing, and precision repair execution, with ground-controlled operation eliminating rope-based climbing.
The company serves three primary B2B segments: wind farm developers/owners, wind turbine service companies, and wind turbine OEMs. Its value proposition centers on an 80% reduction in service time, cost, and risk compared to conventional rope-access methods, with two-person teams able to service six blades (two full turbines) per day and complete a single blade in under 9 minutes. Reblade monetizes through enterprise service contracts (professional services model) and technology licensing/co-development with strategic partners. Pricing is not publicly disclosed and engagements are quote-based on multi-year contracts.
The company operates from an R&D headquarters in Mørke, Denmark, and is led by co-founders Frank Kjerstein (CEO) and André Alexander Westergaard (CTO). It has assembled an international team of approximately 20 full-time engineers including multiple PhDs, post-docs, and a professor. Reblade has secured non-dilutive grant funding from three EU programs (Eurostars, Eureka, EIC Accelerator), won the Danish AI Award in 2023, and is currently preparing for a Series A round targeted for 2027 to support global commercialization across Europe, India, the US, Australia, and Latin America.

Reblade product offering
Product offeringCore offering
Reblade develops and operates a drone-based automated leading edge erosion (LEE) repair system for wind turbine blades. A flying drone carries a miniaturized factory with four attachable robotic modules (cleaning, grinding, LEP coating, and custom) that ground-controlled crews deploy to clean, grind, coat, and paint turbine blade leading edges in minutes, eliminating rope-based climbing. The company also licenses the technology and co-develops custom add-on modules with strategic partners.
Product overview
Reblade offers a drone-based leading edge erosion repair system (the core product) consisting of four attachable robotic modules: Cleaning Module, Grinding Module, LEP Coating Module, and Custom Modules. The system uses computer vision, sensors, and cloud software to enable two-person teams to perform complete turbine blade repairs in under a day, achieving an 80% reduction in service time and costs compared to conventional rope-based methods.

Reblade competitors and assessment
Company assessmentEmerging players
- Skyven Technologies: US-based drone wind services company specialising in blade de-icing and cleaning. Overlaps with Reblade on the drone-based leading edge cleaning module and on wind farm enterprise GTM, but narrower scope (cleaning/de-icing only).
- SkySpecs: US-based drone analytics and blade inspection platform for wind operators. Comparable in drone-driven wind O&M workflow and customer base, though primarily focused on inspection and analytics rather than active repair.
- Perceptual Robotics: UK/Europe-based autonomous drone inspection company focused on wind turbine blades using AI-driven visual analytics. Competes in adjacent drone-and-AI inspection workflows and shares the same wind farm developer customer segment.
- Energy Robotics: Germany-based provider of autonomous robotic inspection platforms for energy assets, including wind turbines. Comparable on AI-driven robotic inspection of wind assets and similar enterprise customer base.
Direct peers
- Rope Robotics: Danish robotics company offering automated blade leading edge repair using crawler-based robotic cells rather than drones. Most direct competitor — same customer base (wind farm developers, OEMs, service companies), same core use case (LEE repair), same geography of origin, competing solution to the same rope-based pain point Reblade targets.
- Aerones: Latvian company providing robotic and drone-enabled wind turbine blade inspection, repair, and maintenance services. Direct competitor in drone-based blade servicing for OEMs and wind farm operators across Europe and the US, with overlapping GTM into enterprise service contracts.
- BladeBUG: UK-based developer of crawling robots for wind turbine blade inspection and repair. Targets the same wind O&M pain points as Reblade (rope-free blade access) and is competing for similar enterprise customers, though with a crawler rather than drone architecture.
Broad incumbents
- Cyberhawk: UK-based drone inspection and data services company with broad industrial asset coverage including wind. Larger incumbent with established enterprise relationships across wind OEMs and operators; overlapping GTM into blade inspection/maintenance workflows.
- Vestas: Largest global wind turbine OEM and service provider, with its own blade service organisation offering proactive maintenance and LEE programmes. Sets competitive benchmark for Reblade in OEM service contracts and could integrate competing robotic or drone solutions of its own.
- DNV: Global energy advisory and certification body active across wind O&M, including blade integrity, inspection frameworks and decommissioning. Adjacent incumbent influencing standards, certification and risk acceptance that Reblade's drone repair tech must satisfy.
