Lemma has launched Lemma Integral, an AI-first adtech platform designed to change how advertisers view and utilize out-of-home media.

Lemma Integral provides full-funnel visibility, enabling advertisers and marketers to plan, track, retarget and optimize OOH campaigns with the same precision and accountability previously reserved for digital channels, according to a press release.

At the core of Lemma Integral's AI engine is the proprietary Lemma Audience Graph. Built using multiple non-personal persistent identifiers and enriched with data from various providers, the graph maps, and profiles millions of audiences globally.

This enables the platform to identify high-intent segments and activate precise retargeting across digital channels, ensuring brands can continuously engage these audiences and drive measurable outcomes.

"Brands today need media strategies that are both impactful and accountable. With Lemma Integral, we were able to integrate data driven DOOH into our media mix and connect it seamlessly with digital channels. This helped us shorten the path from exposure to transaction and deliver significantly stronger returns. It's a clear signal of how outdoor can evolve into a much more performance-driven channel for digital-first brands," Andrew Fox, CEO of SuperJeweler.com and its sister company Hansa USA, said in the release.
