What tonwelt does
tonwelt GmbH is a Berlin-headquartered, privately held provider of visitor guiding solutions and audiovisual content production services for museums, galleries, heritage sites, and corporate experience centers, founded in 1997 and operating across 35+ countries through wholly-owned entities in Germany, France, the UK, and Turkey, plus certified resellers in India, Israel, Canada, and Austria.
The company's core offering is an integrated ecosystem combining proprietary hardware—the supraGuide family of audio and media guides (ECO, MULTI, TOUCH, TOUCH4, DIVA, SPHERIC, S-LIGHT, TRAVEL), tourGuide group guiding systems, and supporting accessories (supraCharger stations, OptiRack/Opti10 storage, dBA-5 headphones)—with the supraCMS multiplatform content management system and in-house creative production via tonwelt Studios. Technical differentiators include RF/IR-based automatic content triggering, binaural/HRTF spatial audio with compass-linked sound sources in SPHERIC, lip-synchronous AV synchronization, and accessibility features (Braille controls, induction loops, audio description, sign language).
Revenue is generated through hardware sales of devices and accessories, professional services covering content creation and AV integration, rental solutions for temporary exhibitions and events, and recurring supraCMS platform licensing. Sales are consultation-led enterprise deals with custom quotes per project; pricing is not publicly disclosed. The customer base spans marquee cultural institutions (Louvre, V&A Museum, Schönbrunn Palace, National Museum of Denmark, Bern Historical Museum/SNB, Giant's Causeway/National Trust), automotive and industrial museums (Mercedes-Benz Museum, Völklinger Hütte, STIHL), and consumer brand experiences (Pilsner Urquell).

tonwelt competitors and assessment
Company assessmentDirect peers
- Orpheo Group: Paris-based global provider of audio guides and multimedia visitor interpretation solutions for museums, cultural sites, and tourism. Direct competitor with overlapping product categories (audio guide hardware, content, AV integration) and similar flagship museum clients.
- Acoustiguide: Long-established provider of audio guides and multimedia tour content for museums and cultural attractions worldwide. Competes head-to-head with tonwelt on enterprise museum contracts and offers comparable hardware + content + CMS solutions.
- Antenna International: John Lennon-founded visitor experience agency producing audio guides, multimedia tours, and digital interpretation for museums and cultural institutions globally. Competes in the same RFP process for marquee museum accounts as tonwelt.
- GuideID: European provider of museum audio guides and multimedia visitor devices with a similar product portfolio spanning hardware devices, content production, and multilingual tour delivery for cultural institutions.
Broad incumbents
- Sennheiser (Tour Guide / Visitor Audio division): Global professional audio incumbent with a tour guide and visitor audio systems business that overlaps tonwelt's group guiding and audio guide offerings. Wider audio portfolio (consumer, pro, broadcast) but competes in the same venues for tour guide RFPs.
Emerging players
- IZI.travel: App and platform for self-guided museum and city tours, offering BYOD-based multimedia interpretation. Represents the smartphone-app alternative to tonwelt's dedicated hardware, particularly relevant for cost-conscious smaller museums.
- Smartify: App-based museum interpretation platform using image recognition to surface multimedia content on visitors' own devices. Direct substitute for tonwelt's hardware-led approach in mid-market museums and a key competitive threat.
- STQRY: Mobile app and CMS platform for museum and visitor centre self-guided tours, offering BYOD-based tours, collection browsing, and AR features. Competes with tonwelt's PWA and supraCMS offerings in the software layer.
- Cuseum: Digital engagement platform for museums offering app-based tours, AR, beacons, and analytics. Competes with tonwelt's CMS-plus-device ecosystem particularly for North American museums seeking app-first solutions.
- Bloomberg Connects: Bloomberg Philanthropies' free museum app and content platform offering audio tours, collections, and visitor wayfinding. A heavyweight app-first competitor that pressures tonwelt's pitch in mid-market and budget-constrained museums.
