BRIEFING

Jared's family saves through a tanda: a group pools money and each member takes a turn with the whole pot. We asked what that looks like with a brokerage account.

In FrontierFund, "settlers" form a ranch, deposit into a shared balance, and vote on every move: buying a stock, withdrawing, or kicking a member. Trades price live through the Alpaca API. It's a React Native app on Expo talking to a FastAPI backend on DynamoDB, all running in Docker. We didn't place, but we shipped it working.
