What Penny does

A buying agent built for the agentic economy.

Discovery on autopilot

Describe what you want in plain English. Penny searches across marketplaces, agentic storefronts, and resale to surface the best fit.

Always watching prices

Set a budget. Penny tracks price drops, coupon stacks, and inventory across sellers — pouncing the moment the math works.

Negotiates in real time

Counters sellers and other shopping agents on your behalf with strategy tuned to your max price and urgency.

Buys when it's right

Auto-buy under your ceiling, or approve big calls in one tap. You stay in control, Penny does the chasing.

How it works

Three moves. The rest is Penny's problem.

01

Tell Penny what you want

“Find me a standing desk under $400” or “watch Sony WH-1000XM5, snag below $280.”

02

Penny goes to work

It researches, compares, negotiates, and bids — across marketplaces and other agents — 24/7.

03

You approve the win

Get pinged only when it matters. Auto-buy small stuff. Approve the big calls in one tap.

You vs. the network

Real saves. Live across Penny's buying desk.

Every counter, coupon stack, and price drop adds up. Penny's network has already saved members millions — and the agent gets sharper with every bid.
