The evidence.
WHY LÜMN EXISTS
In the spring of 2024, I was sitting on a bench in Toulouse reading a book. A man approached me with no phone out, no camera I could see. He stood over me while I sat, asking questions I didn't ask for, in a language I didn't speak. I was disoriented. I was scanning him for a camera the whole time. I found nothing obvious. Then I noticed his glasses.
A day later, someone forwarded me a TikTok. There I was, face visible, expression confused, the whole interaction played back for an account with tens of thousands of followers I had never heard of. I spent a week demanding it be taken down. I watched it get shared while I waited. When it finally disappeared, I couldn't shake the feeling that I had no power in any part of that experience. Not while it was happening, not after.
LÜMN is my answer to that.

THE PROBLEM
Every app asks for consent. No one filming you does.
Smart glasses. Phones held at hip height. Wearable cameras on strangers. The tools that can capture and identify your face in public have never been this small, this cheap, or this common. Anyone can record you without your knowledge, and most of the time, there's nothing you can do about it.
LÜMN exists because privacy in public shouldn't mean hiding. We're building hardware that's discreet enough to wear every day and effective enough to matter, so you can move through the world on your own terms.
What We're Building
A new layer of personal infrastructure.
Face-Forward Protection
Your Identity, Your Choice
Protection You'll Actually Wear
How It Works
Invisible by design.
Presence is not consent.
Consent requires a choice. When the camera is invisible and you never see it coming, there is no choice. LÜMN exists to give it back.
