Technology meets storytelling

At the crossroads of art, technology and history.


Designing immersive experiences anchored in place, guided by meaning, and felt through emotion.

End-to-end creation, entirely in-house

At Lotchi from concept to launch, everything is crafted in house.


We oversee the entire production pipeline of our original creations, ensuring a seamless coherence from artistic intent to public experience.

Technical hub powering LOTCHI’s creations

Today, our Technical Hub operates a fleet of over 80 video projectors and a wide range of equipment, with a dedicated team of specialists running our immersive experiences daily across the world.

At the heart of LOTCHI, our technical hub is where vision takes form, a unique force shaping the future of video mapping.

Imagining experiences beyond the ordinary

LOTCHI brings creators, engineers, designers, historians, musicians, scenographers and visionary minds together, to imagine new ways of experiencing beauty.

Shaped by memory,
Awakened by stories.

Our approach is simple. Places are not backdrops.


They are living structures carrying memory and stories waiting to be revealed.

Crafting new forms of immersive storytelling

LOTCHI is built around a creative studio, a technical division and dedicated in-house teams for production, marketing and deployment.

Within the studio, we explore and shape the immersive experiences of tomorrow.
