We built Halden to do one thing a day, after four years of writing it on a sticky note every evening.
- 2025Started on a sticky note
- 120kPeople pick their thing in Halden
- 6People make it, in Oslo and Valencia
How we decide what to build.
Calm over clever
No badges, confetti or red dots. A quiet desk, not a slot machine.
Your data is yours
No ads, no tracking, nothing sold. Export everything whenever you like.
Forgiving by design
A missed day is marked and left alone. Unfinished things move on.
Paid for by people
Pro subscriptions fund the work, so we answer to the people using it.
Six people, two cities.
