Donecle Secures €10M to Scale Autonomous Aircraft Inspection — OEM Authorization Opens Fleet-Wide Opportunity

Toulouse-based Donecle has built a credible early position in autonomous drone-based aircraft inspection, accumulating deployments across commercial airlines, MRO operators, and NATO-aligned defense programs over a decade of operations. A €10M growth round closed in April 2026 — on top of a €5.6M Series A in October 2023 — brings total disclosed funding to approximately €16.6M since founding in 2015. The capital arrives at a critical inflection point: Donecle has the regulatory authorizations and customer references to pursue scaled adoption, but must now demonstrate repeatable multi-fleet deployment with a 17-person team operating across multiple jurisdictions.

Business Overview

Donecle’s commercial footprint spans three segments — commercial airlines, MRO operators, and defense — a diversification that provides resilience against sector-specific downturns. Confirmed deployments include Viva Aerobus (Mexico, A320 fleet), Jet Aviation (Switzerland), Tarmac Aerosave, AFI KLM E&M subsidiary Barfield (Americas), LOTAMS (Poland), Regional Jet Center (Netherlands), and defense programs with the UK Royal Air Force and the French DMAé/Dassault Aviation Rafale maintenance program.

The RAF contract renewal in April 2024 is a meaningful commercial signal. Repeat purchasing in defense — where procurement cycles are long and switching costs are high — indicates operational value beyond initial pilot deployments. The Rafale program integration, involving both Dassault Aviation and the French defense procurement agency, validates the platform in a high-security, high-consequence maintenance environment. MODERATE CONFIDENCE on revenue scale; no figures have been publicly disclosed.

The company expanded its technology portfolio through the acquisition of Dronétix in May 2022, and consolidated French operations into a Toulouse office in 2024.

Technology

Donecle’s core hardware is an autonomous UAV system using laser-based positioning engineered specifically for GPS-denied metallic hangar environments — a technically meaningful distinction from generic vision-SLAM or GPS-dependent approaches that degrade in proximity to large metallic structures. The system supports single-unit or swarm operation, covers airframe exterior, landing gear, and engine areas, and completes a full aircraft inspection in approximately two hours, with roughly 25 minutes of active flight time.

The software stack comprises two fielded products: the Aircraft Inspection Platform, which handles digital records, defect traceability, and compliance reporting with CMMS integration capability; and Iris GVI, an AI-driven general visual inspection module authorized by both Boeing and Airbus in October 2024 for integration into GVI maintenance workflows.

The inspector-in-the-loop validation model — where AI flags anomalies and a qualified inspector makes airworthiness decisions — is the operationally appropriate architecture for current regulatory frameworks and reduces liability exposure for MRO operators.

A September 2024 joint testing program with metrology firm 8tree at Toulouse targets expansion into quantified damage assessment, including dent measurement and lightning strike mapping. If productized, this would meaningfully increase revenue per inspection event.

Autonomous UAV Inspection System	UAV	Fielded	Laser positioning for GPS-denied hangars; swarm-capable
Iris GVI	Software	Fielded	Boeing + Airbus OEM authorization; AI defect detection
Aircraft Inspection Platform	Software	Fielded	Part-145 compliance integration; CMMS connectivity

Market Position

The dual Boeing and Airbus authorization for Iris GVI — achieved in October 2024 — is the most consequential milestone in Donecle’s history. OEM authorization substantially lowers adoption friction: MRO operators and airlines working within existing OEM maintenance frameworks can integrate Donecle’s workflows without requiring separate engineering orders or deviation approvals. The pathway to inclusion in official maintenance manuals would drive fleet-wide standardization rather than site-by-site negotiation.

The Swiss aviation authority approval for Jet Aviation’s Part-145 operations establishes a regulatory playbook that is, in principle, replicable across EASA and FAA jurisdictions — though each approval remains a resource-intensive, jurisdiction-specific process. HIGH CONFIDENCE on the regulatory milestones; MODERATE CONFIDENCE on the speed of replication across jurisdictions given the company’s current team size.

Competitive pressure exists from specialized peers including Mainblades, and from larger incumbents such as ST Engineering and Rolls-Royce, which have resources to develop or acquire equivalent capabilities. General-purpose drone platforms could also commoditize the hardware layer over time, making software defensibility — particularly the accumulated AI training data from 10+ years of aircraft-specific inspection — the more durable moat.

Outlook

The €10M April 2026 raise provides runway to address the central execution challenge: converting lighthouse deployments into standardized, multi-fleet recurring contracts. The 17-person headcount is the most visible constraint. Supporting global deployments across commercial and defense segments, navigating multi-jurisdictional regulatory approvals, and building enterprise software features simultaneously requires either aggressive hiring or a robust partner leverage model — neither of which has been publicly detailed.

Three catalysts warrant monitoring over the next 12–24 months: formal inclusion of Iris GVI in Boeing or Airbus maintenance manuals; EASA or FAA approval for drone-based GVI workflows; and announcement of a first multi-base fleet-wide deployment contract. Any one of these would materially de-risk the scaling thesis. Absent them, Donecle remains a well-positioned but unproven-at-scale operator in a category it helped define.
