Have a trefika
with us.

Trefika (n.) the 3 o'clock coffee break. The deliberate afternoon pause when colleagues leave their desks, gather over coffee, and let the conversation roam. The part of the day people look forward to. The one that returns you to your work with a better idea than the one you left there. (from the Swedish.)

Trefika app on iPhone

Trefika.

An app about the ritual itself. Schedule a virtual coffee with a friend, or RSVP to an in-person one nearby. A small reminder that the best ideas don't always arrive at your desk.
