Rivoyre Ingénierie

What Rivoyre Ingénierie does

Rivoyre Ingénierie is a French private engineering firm (SAS) founded in 1990 and headquartered in Valbonne Sophia-Antipolis, with a branch office in Lorient. The company specializes in the structural calculation and design of ultralight composite (carbon fiber, glass fiber) and aluminum structures, primarily for the marine sector. Its deliverables include calculation notes, workshop-ready construction and draping plans, expertise reports, and construction monitoring, produced using Nastran, Catia, Solidworks, and Rimast 3D numerical calculation software. The firm holds certification approvals with five major maritime classification societies (RINA, ABS, Lloyd's Register, DNV GL, Bureau Veritas) and claims a track record of more than 300 custom masts delivered worldwide, including carbon masts used by IMOCA 60 Vendée Globe campaigns.

The customer base is dominated by enterprise B2B clients — shipyards, naval architects, racing teams, and boat builders — across luxury sailing yachts, motor yachts, racing multihulls, workboats, and, more recently, aeronautics, civil engineering, industrial, urban furniture, and artistic projects. Notable clients include Sunreef, Couach, CNB, Briand, Gunboat, Groupama, Subsea 7, Thales, and Eurocopter, plus the Ville de Cannes for a carbon-fiber landmark reconstruction.

The business model combines project-based professional services fees (custom quotations per scope, multi-year contracts) with a recurring 15% royalty per series-produced unit from the second copy onward, monetizing design IP over the production life of proven platforms. Go-to-market is sales-led B2B engagement with direct client quoting, supplemented in 2025 by trade show presence at Cannes Yachting Festival and METSTRADE Amsterdam and a dedicated Lorient mast/rigging office embedded in France's principal racing-yacht cluster. The company is founder-owned (Franck de Rivoyre as Founder & Ambassador, with Hervé Tanneur and Christophe Larose as associate/technical directors), privately held with no external investors identified.
