Nubart's story

In 2013, as she was publishing her first e-books, the Spanish-German author Rosa Sala had an interesting idea:

Relevant digital content, as books, music and audio guides, should be made tangible to increase its perceived value.

Tangible things can be wrapped as a gift, sold in brick-and-mortar stores, kept as a souvenir or signed by an author or musician, all things that she was missing with purely digital content.

What started as a weird idea shared in a conversation with friends gained momentum. During a hot summer in Barcelona that very same year, Rosa and her co-founders Jordi Pérez (COO) and Simon Effing (CTO) brought our company Digital Tangible SL to life.

To achieve the mission of making digital things tangible, we decided to produce nice-looking cards that people want to keep as a souvenir. Simon Effing developed a system that converts unique codes printed on them into a non-transferable key that provides access to the multimedia content without requiring an app nor a sign-in. Our IP-protected LWAC-system was born.

We started with ebooks and audio books and we found customers quickly, but that happened to be a too bumpy road. In 2016 we discovered that our cards with unique codes can empower museums and other venues around the world by offering audio-guides without the hazzle of devices nor the inconveniences of apps. We also learned that the World is full of venues that can be audio guided, but have never considered this option before.

We called it Nubart, the Audio Guide Visitors Keep.

Since then, our team has been growing significantly. We opened a second office in Berlin. Our customers are all around the World. And hundreds of thousands of visitors have enjoyed our audio guides.

We would love to welcome you next!
