About this app

Billy makes the invisible, visible.


Scan a receipt or log a purchase and instantly see the ownership chain behind the brands you buy — from the store to the parent company to the shareholders who profit.

Billy maps the hidden structure of your spending so you can make informed choices about where your money actually goes.

What billy does:
- Traces ownership chains from brand to parent company to major shareholders
- Shows local and independent alternatives in your area
- Tracks your spending patterns across corporate vs. independent businesses
- Connects you to collective action — see what your community is doing together
- Surfaces verified data like lobbying records, labor practices, and environmental impact through linked sources

Your data stays on your device. Community features use anonymous aggregates only — no personal information is ever shared or sold.
