Scale the
of your ad

Illuma is contextual advertising technology with an intelligent difference.

Illuma uses AI to learn from online browsing behaviour during live campaigns, identifying and reacting to the content consumption of your target audiences. Using these insights, Illuma expands your campaign into similar high-performing contexts instantly and dynamically, finding engaged new audiences at scale.

Illuma delivers relevance, reach and results, whatever your campaign goals.

The Illuma advantage

Scale with relevance

Illuma works during live campaigns, learning and expanding in real time to find relevant new audiences at scale. While other technology is static and pre-defined, Illuma reacts to find new opportunities based on live intelligence.

Certainty, not guesswork

The relationship between context and ad engagement changes constantly. Illuma keeps in step by removing predefined guesswork and instead targeting impressions based on what is working, moment to moment, during each campaign.

Cookieless and privacy-friendly

Illuma delivers better reach, relevance, and performance, without relying on cookies, personal data or identifiers. Illuma is compliant with GDPR, CCPA and ePrivacy, and, more importantly, with users’ desire to protect their personal data online.
