Our Motivation & Vision

When Annette, co-founder of Frameless, wanted to show her newly rented apartment in Vienna to her parents back in Germany. She couldn’t do any better than normal pics and a Skype video tour, which was a poor reflection of reality and didn’t give a feeling of the space and layout. It was very clear to us that capturing the entire apartment and sharing it as virtual tour provides a much better understanding of the place. And we thought about several use cases where such immersive experiences would bring tons of benefits in every day scenarios. We saw a big gap in the market as existing tools make capturing places and creating immersive walk-throughs an expensive, time consuming, and cumbersome process and not easily accessible to every day users. So we started working on a solution.

Our vision is to enable the 3 billion people carrying around smartphones to create immersive 3D content, instantly and everywhere. To achieve that, we develop a new innovative application that makes it very easy for users to capture entire places, regardless of size or number of rooms, or if it’s indoor or outdoor, and convert those places to personalized immersive experiences.


Frameless is a tight-knit team of analytical, creative, and curious VR enthusiasts who are committed to bringing down barriers and complexity of creating immersive digital experiences by developing novel solutions that makes it very easy for people to do that.
