On‑Chain
Discovery that feels like a memory you haven't made yet.
We combined years of scientific research on novelty‑seeking and habit formation with blockchain verification, so every recommendation is both delightful and trustworthy.
On‑chain trust
Every review and rating is written to the chain the moment it's submitted, so recommendations can't be quietly edited or bought.
Built for spontaneity
Open the app, get three ideas within walking distance, in under five seconds — no endless scrolling required.
Science‑backed picks
Our recommendation model is grounded in published research on novelty, mood and social connection — not just popularity.
A small crew that grew up on scavenger hunts.
We're a team of scientists, builders and lifelong explorers based between Alexandria and Amsterdam. Sample profiles below — introduce your real team here.

Kindness first
No dark patterns, no shame‑based streaks — just gentle nudges toward a good time.
Made to be remembered
