Hi, I'm Julien Nehring. I build across housing, music, sport, the city and social creation — five projects, one lab, shipped solo and iterated in public.

shipped solo.
I'm Julien Nehring — a Staff PM by day, a builder the rest of the time. Hatchlab is where I turn ideas into real products instead of letting them rot in a notes app.
No pitch decks, no funding rounds. Just useful things shipped fast, then sharpened with real feedback. Based in the Paris area.
