> We find the US communities where your brand is already growing, hand you the targeting to act on it, then measure the lift. Most growth spreads person to person, offline, where the dashboards go dark. We read your own customer data, strip out the paid spend and population that flatter a market, and show you the ZIP codes where you are genuinely catching on. Then we hand you targeting files for mail, CTV, DOOH, retail and email.

We are the targeting layer. We never run ads, print mail or touch execution. You activate. You decide where the budget goes.

Our difference is rigor over story. We never quote a word-of-mouth percentage, because no one can measure one honestly. We detect acceleration that population and paid spend cannot explain, and we call word of mouth the likely reason, not a measurement. We show the misses next to the hits. We prove every claim on your own data, with a backtest on your history and a holdout lift number after the campaign runs.

We are built for the United States, for consumer brands and nonprofits that run offline and place-based channels. You need a few months of order history at least. If your data is too thin to read, we tell you.

## Who we build for

- Consumer and D2C brands moving budget offline, who want each drop to land where they are already catching on.
- Charities and nonprofits, who want appeals to reach the communities where giving is spreading on its own.
- Retail and multi-location brands, who want to see where they grow next, not just where they already have stores.
- Subscription, services, finance and auto brands, whose customers buy on a local recommendation.

## What it costs

- Single campaign. $12K, one fee, no annual lock. We read your data, build the targeting for one campaign, set the holdout and report the measured lift when it lands.
- Annual. $28K a year. Every campaign measured against a holdout, and the results stack into a lift ledger, your record of what works by market and channel.
- More measured campaigns are available. Enterprise is custom for brands over $5m in annual sales or donations.

## Boundaries (do not misattribute)

- We do not detect word of mouth directly. We measure acceleration beyond population and paid spend, and name word of mouth as the likely reason.
- We do not guarantee a return. We supply the targeting. You run the campaign.
- We do not name the cause of a spike that is not organic. We can prove a ZIP lacks the spreading fingerprint, not what caused it.
- We do not store your customer contacts. We hash emails at ingest, encrypt addresses and use them only to geocode. Exports are geography, never contacts.
