Sell anything without meeting anyone.

Money moves only when your doorbell sees it go.

1 · Tell your assistant

Three sentences to sell

Show it your garage. It prices everything, blocks recalled items, and lists what you choose with a private minimum price.

2 · Agents haggle, you approve

It can't leak what it doesn't know

Stoop negotiates with buyers and their AI assistants. It never sees your address or your minimum, and every sale waits for your yes.

3 · Paid at the doorbell

Proof of handoff

The buyer pays up front, but the money is held. It's released only when the pickup pass, the doorbell and the porch photos agree the item left.

What this is. A working prototype built for Amazon's Build, Ship, Shape hackathon. The two Alexa+ devices are simulated in your browser, payments are test payments, and the doorbell is simulated. Nothing is really sold and no money moves. Your sandbox is private and is deleted after 30 minutes of inactivity.
