About Booki

The Problem

Every friend group that bets on sports together ends up in the same place: a spreadsheet that nobody trusts, a group chat full of "I think I already paid you," and one person doing all the work on Sunday night while everyone else watches the game.

The tools that exist are built for large-scale operations — pay-per-head platforms charging $10/head/week, enterprise software with casino add-ons. Nothing existed for the person running a 10-person NFL pool out of a Google Sheet.

What We Built

Booki is a pick tracking platform for friend groups and private leagues. Organizers invite members, set credit limits, and let the system handle the rest. Odds auto-import from major sportsbooks. Picks are graded automatically when games go final. Settlements are one tap. The ledger is tamper-evident and auditable.

Every financial operation runs through server-side functions with idempotency keys, atomic transactions, and a hash-chain ledger. If a row is modified directly in the database, the chain breaks and it's immediately detectable. This is the level of integrity that friend-group money deserves.
