It all started with a Minolta X-700, at 15, shooting black-and-white film. Arsène Gaillard is an editor and set technician at 23bis, in Lausanne. Trained in graphic design, he moves fluidly between photography, editing and video, with authenticity as his guiding word. He recently edited projects such as AP Pollypocket and TDH Santé Guinée.

Cédric Heckly Camera Assistant & Equipment Manager
Assistant caméra et responsable du parc matériel chez 23bis, Cédric assure le bon fonctionnement technique de chaque tournage. Ancien ébéniste reconverti dans la vidéo, sa rigueur technique est un pilier silencieux de chaque production.
Cyril Jaunin Art Director
In 2012, Cyril graduated as an Interactive Media Designer with a passion for graphic arts and an insatiable curiosity. Cyril Jaunin is Art Director at 23bis, in Lausanne. A self-described generalist, he turns this wide range of interests into original ideas and sharp art direction. When he isn't daydreaming on long bike rides, he digs into obscure subjects to find the spark that makes the difference.
Gabriel Saurer Production Director & Co-founder
As a child, Gabriel was always building things and inventing games. Filmmaking became the one he never let go of. Gabriel Saurer is co-founder and Production Director of 23bis, based in Lausanne. Day to day, he keeps the company running smoothly, oversees production and looks after the team's wellbeing. Off the clock, he sews his own clothes, cycles across Switzerland and keeps trying the same ollie.

Lisa Keravec Production Assistant
Lisa grew up in south-west France, right by the ocean, a haven she remains attached to. Her eye for beauty led her to photography, which she learned at a production agency in Paris, where she lived for seven years. Lisa Keravec is a production assistant at 23bis, in Lausanne. Shoots, the nonprofit world, press officer for wines and spirits: her common thread is creating connection. Off work: free dance, yoga, swimming and nature.

How we work
We've been B Corp certified since January 2022. What counts is what stands behind that label: the way we work. A four-day week, a pay ratio capped at one to six, every production measured for its carbon impact, and a goal of 65% positive-impact projects. A culture built on curiosity and accountability, and on a simple idea: good content can make things better.
