## Work Experience
- Co-Founder at Papegaai (Jan 2026 – Present)
  I co-founded Papegaai because something hit me: Music artists have lost something.

There was a time when music came with a universe. Album covers you'd flip over and study from every angle. Music videos that emotionally extended what you'd just listened to. Art direction that gave every project a visual identity.

All of that created a bond. Narrative, emotional, almost physical. Between the artist and their fans.

Today that bond is gone.

Music has become a feed. Spotify, TikTok, Instagram. Streams, views, plays. No more format, no more object, no more universe to inhabit.

Artists reach more people than ever. And are paradoxically further from their fans than they've ever been.

We're fixing that.

Papegaai is a mobile entertainment studio that gives artists back a narrative and emotional territory. We turn their universes into IP. Their sounds, their vibes, their worlds. Into experiences you live, not passively consume.

We created Lumix.
Full screen. Animated. Built for mobile, not adapted to it.
You swipe, the story moves. The images move. The rhythm pulls you in.

It's not a comic. It's not a webtoon. It's not a music video.
It's something else.

First territory: French rap.
50% of streams. 0% of narrative universes.

The gap is there. We're charging right into it.
