Sandwich Bets

Social prediction and lunch-debt ledger

One Sandwich Max.

Sandwich Bets started with a tiny social failure: two friends make a dumb prediction, forget the terms, and later remember the outcome differently. The joke only works if the system remembers exactly what was proposed, what changed, who accepted it, and whether the resulting sandwich was ever delivered.

That turned a novelty into a real product exercise. The app separates theatrical odds from settlement, caps every consequence at one sandwich, versions negotiated terms, keeps the ledger private to participants, and leaves an obligation open until lunch is delivered or forgiven.
