Honest

A strong lead, never a promise

A resemblance is a reason to test a market, not a guarantee it will work. We frame every expansion candidate as exactly that, so you go in with a clear read and hold something back to measure.

Test

Ready for a real trial

The shortlist comes formatted for the channels you run, so you can put a small campaign into a few new markets, keep the rest as a holdout and see what actually landed.

Common questions

Can you really find markets where I have no customers?

Yes. We rank the full set of US markets by how closely they resemble your best ones, so the shortlist includes places you have never sold in.

How is this different from buying a demographic audience?

We start from your own winning markets and look for their real world twins, rather than guessing from a demographic profile alone. It is grounded in where you already succeed.

Is the shortlist a guarantee?

No. It is a ranked set of strong candidates. That is why we hand you the files with a holdout built in, so you can prove which new markets worked.
