What Rieger Orgelbau does
Rieger Orgelbau GmbH is a private Austrian pipe organ builder founded in 1843/1844 by Franz Rieger, now in its seventh generation of operation. The firm designs and constructs custom pipe organs for institutional customers — churches, cathedrals, concert halls, and universities — across more than 16 countries in Europe, Asia, the Middle East, and North America, and has installed nearly 1,890 instruments over its 180+ year history. Landmark projects include the 134-stop organ at Vienna's St. Stephen's Cathedral, the 86-stop organ in the Musikverein's Goldener Saal, the 91-stop organ at the Philharmonie de Paris, and the 124-stop organ at Helsinki Musiikkitalo (the largest organ in Finland and the second-largest Rieger has ever built). The firm also operates a substantial historic restoration business.
Rieger's competitive position rests on full vertical integration at its Schwarzach, Vorarlberg workshop: the firm casts metal sheets, shapes wooden pipes, builds reed pipes, manufactures windchests and consoles, and develops its own proprietary electronic control system, the Rieger Electronic Assistant (REA), now in its second generation. Approximately 60+ specialists from 14 nations cover woodworking, metalworking, voicing, electronics R&D, and administration, supported by an active apprenticeship program training 11-14 organ builders at any given time. Innovations such as proportional key and stop actions, variable wind pressure systems, and remote maintenance capabilities differentiate the firm's technical offering.
Revenue is generated primarily through one-time custom organ construction contracts (each instrument individually designed and priced), restoration projects for historical instruments from different eras, and recurring lifelong maintenance contracts on the installed base. The firm sells directly to institutional buyers with no intermediaries, using a consultative, project-based enterprise sales motion. Geographic reach is global, with a strong European core and growing presence in China and other international markets. Pricing is not publicly disclosed; each project is individually negotiated. Ownership remains private under CEO Wendelin Eberle, who has led the company since 2003.
