Our Motivation & Vision

Annette, co-founder of Frameless, wanted to show her new Vienna apartment to her parents back in Germany. But photo sharing and video chatting weren’t enough to convey the feeling of the space. She wanted to show her entire apartment in virtual reality. Better yet, to capture it entirely with just her smartphone.

In a future where VR has the potential to impact everyday life, content is king. The problem today is with the speed and volume of content creation. Creating VR content requires years of training and access to expensive and cumbersome tools. Our vision is to empower billions of people around the world with the ability to create immersive content anywhere and anytime. Our mobile app will easily transform any indoor or outdoor environment into an immersive virtual walkthrough. This is made possible through the use of state-of-the-art image processing techniques and our novel robust localization technique. Plus with the power of WebVR and WebGL, anyone can experience these virtual tours with or without a VR headset.

These 360° tours can also be augmented with extra content such as videos, landmarks, and text bubbles. Not only will family and friends benefit from sharing these informative experiences, but so too will countless industries. Including: real estate, tourism, factory maintenance, and immersive journalism.

Together we will revolutionize VR content creation!


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.
