Unamino

The hard part of any group decision isn't the planning. It's getting everyone to actually commit. Someone goes quiet, someone fronts the money, someone backs out, and the plan dies in the group chat. Unamino is an AI consensus agent. It gets a group to one plan everyone has explicitly agreed to, and no money moves until every person has said yes. How consensus works: 1. Everyone agrees on the same plan: no card needed 2. Everyone approves their own share, which becomes their personal cap 3. A card hold (not a charge) locks in each person's commitment 4. Only when every single person has approved does anything get booked 5. Each person is charged their real share, never above what they approved Consensus is protected, not assumed: • Each person's limits (budget, room, meals, flight times) are enforced in code • If the price rises over 5%, everyone has to re-agree • If someone drops out, the agent re-plans for the people left • AI-written nudges bring quiet members back into the decision • If anything fails, everything is reversed and holds are released The demo shows a group trip, the first place we're applying it.
