Custom Audiences & Segments
Audiences that do not exist as a checkbox anywhere: language and heritage segments, foreign-educated professionals, alumni, credential holders, built and delivered to your ad platform.
Some audiences require assembling three datasets and a method. Hispanic homeowners in three states built from Census surname methodology and language data, validated against a vendor-coded subset. Professionals in the US with degrees from Indian universities, for an immigration law practice. Graduates of a specific program abroad. Licensed professionals in a category no compiler tracks.
We build the audience, measure its accuracy on a holdout, and deliver it as a file or directly as a matched audience to Meta, Google or LiveRamp.
Sample rows
Illustrative and synthetic. Real samples for your geography are a reply away.

How it is built
Each audience is a small project: define, build from the relevant graphs, validate on a labeled subset, report the measured rate, then deliver. We do not sell audiences we could not measure.
Questions we get
Do you deliver to ad platforms?
Yes, as hashed custom audiences to Meta, Google and LiveRamp, or as files to your DMP.
What about sensitive categories?
We follow platform policies and applicable law, and we decline briefs that would target protected classes for adverse purposes.
