Measurement that keeps up with media
Feather measures what advertising actually changes in people's minds. We run brand lift studies for mobile, CTV, out-of-home, sports sponsorship and AI answers across Europe, and report within days of campaign end.
Why we built it
Brand lift used to mean a research agency, a panel, a minimum spend and a six-week wait. By the time results arrived, the campaign was over and the budget was spent. Most campaigns were never measured at all.
Feather was built to change that. We survey real people inside or right after the ad they saw, compare them against a control group that did not see it, and report the difference. No panels, no cookies, no guesswork about who was exposed.
How we work
- Deterministic where possible. Exposure comes from the ad server, not from a model or a guess.
- Honest about confidence. Every result is labelled Significant or Directional. We never blend the two.
- Automated, then checked. Delivery and analysis are automated. An analyst reviews every study before it goes out.
- Privacy by design. No cookies, no device IDs, data stored in the EU.
- Results as a service. We run the study. You get the answer, not another dashboard.

Why teams choose Feather
Fast, Checked Results
Survey delivery, data collection and analysis are automated. Every study is then reviewed by an analyst before the report goes out, so speed never comes at the cost of accuracy.
Measurement for Every Campaign
Brands of every size can finally measure what their campaigns are building.
Reports in Days, Not Weeks
Traditional brand lift studies take 4 to 12 weeks. Feather reports arrive within days of campaign end, while there is still time to act on them.
Actionable, Not Academic
Every metric maps to a media decision. eCPLU connects brand measurement directly to spend optimisation.
