What Gelbyson does

Gelbyson is a privately held Italian aerospace company founded in 1947, headquartered in Rome with a secondary warehouse facility in Amsterdam, Netherlands. The company operates through two legal entities, Gelbyson S.R.L (Italy) and Gelbyson Aerospace Corporation B.V (Netherlands), and serves as a sales and service provider across three integrated business lines: OEM-authorized stocking distribution, OEM representation agency services, and in-house Maintenance, Repair, and Overhaul (MRO) operations.

The company's core offering centers on Electrical Power Storage, Generation and Distribution Systems (EPSGDS), battery ground support equipment, safety and survival products, communication systems, and cabin equipment for commercial, military, and business aviation. Gelbyson distributes products from over 35 aerospace brands — including Saft (Ni-Cd aircraft batteries), Safran/ACR Artex (Emergency Locator Transmitters), Concorde, MarathonNorco, Skurka Aerospace (motors/generators), Novega (Underwater Locator Beacons), Switlik and EAM Worldwide (life rafts and vests), David Clark (headsets), Powervamp (ground power units), and others — supported by strategically located warehouses in Rome for commercial spares and Amsterdam for military spares. MRO services are conducted under Part-145 ratings C3, C5, C6, C13, and C18 with approvals from CAA (UK), EASA (EU), EMAR (European Military), and FAA (US), alongside EN 9100, EN 9120, and ISO 9001 quality certifications.

The business model combines hardware sales margins on distributed aerospace components, professional service fees from MRO work and extended warranty programs, and commissions or retainer fees from OEM representation engagements. Go-to-market is primarily sales-led through a direct sales team and a network of sales agents/distributors, supplemented by an e-commerce storefront for standardized SKUs, RFI-driven website engagement, and participation in major aerospace trade shows (Paris Air Show, MRO Europe, Dubai, Singapore, Farnborough). Customer segmentation spans commercial airlines, military operators, business aviation, and third-party MRO providers, with no disclosed customer concentration data.
