Sound Inventor

What Sound Inventor does

Klangerfinder GmbH & Co KG (also known as Sound Inventor) is a Stuttgart-based audio branding and sound design agency founded in 2008 and operating as a privately held GmbH & Co KG with no external venture or institutional investment. The firm positions itself as an "Atelier für auditive Kommunikation" (Studio for Auditory Communication), offering an integrated stack spanning brand strategy, sound design, music composition, spatial audio production, custom software development, and technical implementation for installations and interactive applications.

The company's technical platform combines deterministic audio engineering with custom software: wave field synthesis consulting in partnership with IOSONO GmbH, proprietary intelligent multi-channel player software for multi-zone acoustic ecosystems, 3D augmented audio guides using head-tracking and iBeacons, and bespoke applications built on iOS, MAXMSP, CSOUND, and C++. Its product portfolio is structured around corporate sound identities (Audi Corporate Sound, Audi "Heartbeat" logo, Porsche Soundlogo, Telekom Sound Identity, congstar, Kärcher), spatial audio installations (Haus der Berge, Erwin Hymer Museum, Porsche Pavillon, Mercedes-Benz Museum), and interactive media including VR (Porsche Panamera, Audi Le Mans), AR (MoMA Björk guide, Kunsthalle Mannheim memo), and apps (Volkswagen Sound Journey, Magenta Moon Garden). Revenue is generated primarily through fixed-price project contracts with enterprise clients, supplemented by licensing of a proprietary KE archive of 2,500+ music tracks and 2,000+ voice samples, with delivery supported by a network of 60 composers and 300+ ISDN-connected partner studios.

The customer base is concentrated in five verticals — premium automotive (Audi, Mercedes-Benz, Porsche, Volkswagen, smart/Daimler, Hyundai), museums and cultural institutions (MoMA NY, Kunstmuseum Stuttgart, Kunsthalle Mannheim, Erwin Hymer Museum, Haus der Berge, Mercedes-Benz Museum, Changi Airport), telecommunications (Telekom, congstar), government (Bundeswirtschaftsministerium, Landesvertretung Baden-Württemberg), and consumer brands (Kärcher) — with project delivery documented in Germany, the US, Singapore, Korea, Qatar, and China. The agency is founder-led by Prof. Florian Käppler, who simultaneously serves as managing director and professor of music design at the State Music Academy Trossingen, an academic role that feeds both talent pipeline and thought leadership into the business.
