What Nubart does
Who we are
Nubart develops digital audio solutions that enhance visitor experiences in cultural and tourism environments worldwide.
Founded in 2013, with offices in Berlin and Barcelona, we have become a trusted partner for nearly 200 institutions across five continents.
When we began, we only knew one thing: audio guides should be better. No more outdated devices, no clunky apps.
All our products — from audio guides to group guidance systems, interactive games, AI-translation for events, triggered audio guides for touristic vehicles and synchronized video soundtracks — are QR code-based and work directly in the smartphone browser. No apps, downloads or dedicated hardware required.
Nubart is privately owned, debt-free & profitable since 2016

What makes Nubart different
Our identity
Innovation with purpose
While many solutions add complexity, Nubart's innovation lies in making advanced technology effortless. Our browser-based systems are engineered for stability, scalability, and ease of use, ensuring visitors enjoy a smooth and reliable experience every time.
Not another startup
Worried about working with yet another tech startup that might disappear in a few years? Nubart is privately owned, debt-free, and profitable since 2016. We grow steadily and in a sustainable way, building long-term relationships with clients who value continuity, reliability, and trust.
Commitment to quality
From concept to final delivery, Nubart maintains full control over its production chain. Our international team of professionals ensures that every script, translation, and voice recording meets the highest standards of accuracy and engagement.
Data responsibility
All our solutions comply with European data protection regulations (GDPR). Our analytics provide clients with detailed, anonymized insights into visitor behavior, never at the expense of privacy.
Accessibility
Nubart's audio guides are fully compliant with the Web Content Accessibility Guidelines (WCAG). We are committed to making culture accessible to everyone, ensuring that our Progressive Web Apps can be enjoyed by all visitors, including those with visual or hearing impairments.
We connect people and places through sound, with innovation you can rely on.
Our team
We work from different time zones and speak more than a dozen languages, yet we operate as one team.
What unites us is a shared commitment to combine technological excellence with personal service, ensuring that every client feels supported, wherever they are.
