  • Real momentum, not just size
  • Organic growth, mapped

Anyone can show you a hotspot. We show you which ones are real

A hotspot is usually just your biggest market. Real growth has a fingerprint. We score it, you act on it.

It accelerates

Growing faster than its size and your spend can explain.

It clusters

Concentrated where customers pull in the people around them.

It spreads

Showing up in the markets next door a few weeks later.

The biggest markets weren’t always the ones growing fastest. Once we saw that, we started looking at our data differently.

See where your brand is catching on

We set aside the sales your ads paid for and the sales that come from a place just being big. What is left is real momentum, the markets choosing you on their own.

How we read it

Target

One upload, a ranked list of where to grow

We place every customer on the map and rank your markets by how fast they are catching on. The ones that only look hot get flagged so you do not chase them.

Frequently asked questions

What does porterzip do?

We read your own sales and find the US communities where your brand is catching on by itself. We set aside the sales your ads paid for and the sales that come from a place just being big, so a busy market never looks like a growing one, then hand you the ranked list and measure the lift after your campaign.

How is this different from a heatmap of my sales?

A heatmap shows where you already sold, which is usually just your biggest market. We measure the growth your size and ad spend cannot explain, so you see where you are catching on next rather than where you have already been.

Do you ever see my customers' personal information?

Your contacts never leave your file. We hash emails and encrypt addresses at ingest and use them only to place each customer in a ZIP. Every export is geography, never a contact.

What do I actually get back?

A ranked list of markets scored by momentum, formatted for every channel you run, from direct mail and CTV to email and field marketing. No duplicates, every customer already placed on the map and ready to drop in.

How do you prove it worked?

You hold back a set of markets, we target the rest, and after the campaign we measure how much more the targeted markets grew than the held-back ones. You get a real lift number with honest confidence, not a story.

Can you find markets I am not in yet?

Yes. We rank the full set of US ZIP codes by how closely they resemble your best markets on income, education, housing and age. You get expansion candidates where you have zero customers today, framed as a resemblance read and never a guarantee.

How soon can I see something?

Upload a customer list and we place every customer on the map and score it, then return channel-ready files in minutes.
