How lean coffee works
Lean coffee is a meeting with a democratic agenda: people show up, write the topics they care about on cards, and the room dot-votes on which ones are worth the time. Each winning topic gets a timebox instead of an open-ended slot, so no single subject quietly eats the hour. When the timebox ends the group takes a roman vote, thumbs up to keep going and thumbs down to move on, and the majority decides whether the topic earns two more minutes or the next card comes up.
The format was created by Jim Benson and Jeremy Lightsmith in Seattle in 2009. Their insight was that the agenda is the expensive part of a meeting, and that a group can build one in five minutes if you let it vote rather than argue.
Everything on this board is live and shared. Cards are visible as soon as they are posted, so people can build on each other rather than duplicate topics, and each person holds three dots. A dot comes back when its topic has been discussed, which means people who join late or run out early still get a say in the next round.
