What Decision does

Decision SA, founded in 1984 and headquartered in Ecublens, Switzerland, is a custom composite structures manufacturer operating as part of the Carboman Group (alongside Multiplast in Vannes, France). The company designs and fabricates high-performance composite structures using pre-preg layup, resin infusion, structural bonding, sandwich construction, and a proprietary Thin Ply Technology (TPT). Its manufacturing footprint centres on an Ecublens facility equipped — since a 2019 capacity expansion — with an aerospace-certified autoclave, integrated tooling capability (via SNE-SMM), and non-destructive testing (ultrasonics) plus optical-fiber structural-health monitoring embedded in parts.

The company serves five primary verticals: marine (racing yachts, America's Cup catamarans, Volvo Ocean 65 hulls, IMOCA 60s, luxury motor yachts, electric foilers), aeronautics (Solar Impulse HB-SIA and HB-SIB main structures, Eviation Alice fuselage, Safran engine components, Jetman carbon wings), sport (one-design catamarans, sailing simulators, Olympic timing portals), industry (robot arms, watch cases, microscope covers, aerospace tooling, EMP generator shells), and building/architecture (radio-transparent telecom structures, ornamental domes, retractable chimneys). Decision's revenue model is project-based and sales-led: each engagement is custom-quoted based on materials, complexity and volume, with direct client engagement from conception through tooling, production and certification (ISO 12215, Veritas, GL, Germanische Lloyd). Notable marquee customers include Solar Impulse, Alinghi, Groupama Team France, Gitana/Edmond de Rothschild, Sea Bubbles, Silver Arrows Marine, CGN, Eviation Aircraft, Safran and Thales Alenia Space, alongside watchmaking clients such as Ellicott and Parmigiani. Pricing is not publicly disclosed and revenue figures are not released; headcount is reported in the 11–50 range.
