About

I’m the founder of Lumina, a cultural social network starting in Paris. I began building it from a simple frustration: discovering culture, deciding what to experience and organizing a cultural outing still feels fragmented across event platforms, social media and messaging apps. Lumina brings that journey together — discover cultural events, see what interests your friends, organize outings and build a personal cultural history. I’m a solo, non-technical founder using AI-assisted development, including GPT-6 Astra, to take the product from concept to a working beta. My goal is to build technology that encourages people to spend less time scrolling and more time experiencing culture in the real world.

Lumina - The social network for culture, made for real life

Lumina is a cultural social network for real life. It brings Paris exhibitions, theatre, cinema, concerts and more into one place, then adds a social layer: discover what interests your friends, plan cultural outings together and build your own cultural journal. Instead of endless listings or another attention-driven feed, Lumina is designed to help you choose faster, meet offline and experience more culture.
