More of the right people, in moments that suit your brand.

Reach people through what they care about.

Personas built from your brand find your audience in the content they choose to read and watch, on every device and browser.

Brand safety and suitability, built in.

Every page and video is vectorised before we bid, and your suitability rules apply to every persona. Nothing is bought blind.

Every impression bid for your goal.

MatchOutcome bids on each impression against the metric your campaign is bought on, from clicks to completed views.

You stay in control.

Upload your own personas and brand guidelines, correct anything we inferred, and see exactly what your plan is built from.

From brief to live campaign in three steps.

Share your brand and brief.

Give us your landing page URL and a brief, or upload your guidelines and existing personas. BrandDNA and CampaignDNA capture what your brand stands for and what this campaign has to achieve.

Review your personas.

MatchPersona builds lifestyle, life stage and intent personas and finds the content where each one spends attention. You review every persona and adjust it before launch.

Launch and optimise.

We activate your personas on the Trusted Web and on YouTube, and MatchOutcome bids on each impression for your campaign metric.
