The one-week format
SOTI is straightforward on purpose. A selected group moves into one house for seven days. The middle of the day is for real work. Meals, walks, demos and a few carefully chosen rooms in the host city sit around that work, not on top of it.
Residents do not join to pause their company. Calls still happen. Deadlines still exist. Laptops stay open. The difference is who is around you while you do it — and the fact that you will see those people again at breakfast, not only in a Slack follow-up that never comes.
Accepted members receive a pre-house operating pack with cohort context, useful links, house norms and a draft agenda. The week should start with context, not with a cold room.
