What Sinnex does
Sinnex Innenausbau GmbH is a privately held Austrian luxury interior specialist, founded in 1996 and headquartered in Griffen, Austria, with additional engineering and production sites in Waiblingen and Schweindorf, Germany. The company's core business is the custom design, production, and installation of luxury yacht interiors, focused on superyachts of 60 meters and above, with supplementary work in high-end residences, aircraft, offices, and spas. Production combines traditional joinery and hand-crafted finishing with CAD/AutoCAD design systems and modern CNC machining, and is delivered in-house across paint/lacquer, leather (including exotic goat parchment and fish-skin leather), wood veneers, stone, metallic finishes, and glass, including a dedicated in-house upholstery workshop.
Sinnex's commercial model is project-based, quote-driven, and relationship-led. Projects are secured through direct engagement with yacht owners and, more significantly, through long-term strategic partnerships with the leading European superyacht shipyards — Oceanco, Lürssen, Feadship, Heesen, Perini Navi, and Damen — and with prominent exterior design studios including Nuvolari Lenard, Ken Freivokh Design, Winch Design, and Reymond Langton. The company is a named member of Oceanco's Co-Maker Unlimited initiative, and its reference portfolio includes iconic vessels such as the 87m Maltese Falcon (Perini Navi), the 115m MY Pelorus (Lürssen), the 106.7m Black Pearl (Oceanco), and the 92m Feadship Royal Romance, with a 2015 World Super Yacht Award for the 51m MY Sky. A standalone Refit service covers surface restoration, wear-and-tear repair, and full interior renewal on existing yachts.
Since 2016, operational leadership has been held by a two-person management team of CEO Erika Verachter and Managing Director Wolfgang Walzl, with no disclosed venture or private equity ownership. The company is founder/management-owned, has no subsidiaries, no disclosed M&A activity, and no external funding rounds. In 2022, Sinnex inaugurated a newly constructed building at its Griffen headquarters, materially expanding production capacity. Pricing is not publicly disclosed and is determined per project, with no standard tiers. The German subsidiary operates as Sinnex – Steinheimer Innenausbau GmbH.
