Scale the
of your ad

Illuma is contextual advertising technology with an intelligent difference.

Illuma uses contextual-AI to create solutions for enterprise.
Its real-time scaling technology is used by brands and agencies to boost the results of digital advertising campaigns.

Meanwhile, broadcasters, publishers and online platforms use Illuma to organise, classify and categorise their inventory for commercial activation. 

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.
