Advia is a Madrid-based adtech startup that builds AI-driven digital advertising solutions around what it calls "Active Navigation" — the moments when consumers are actively searching for information — positioning brands as the answer instead of relying on cookies or individual tracking. Its proprietary technology, Vera, uses large language models and multi-agent simulation to replicate the behaviour of thousands of digital consumers and predict where and when an ad becomes relevant across search engines, video platforms and conversational AI. Launched publicly in May 2025 by three ex-Seedtag/GroupM adtech operators, it is hosted at Google for Startups Madrid, is a Google Partner, and closed a €500K pre-seed round in convertible notes in July 2025.
Uses AI to predict which ad a user will find relevant at the moment they are reading, and places brand ads inside publisher content. Advia does the same around moments of active search, and both are paid by advertisers.
Uses AI to predict engagement in context and put native ads next to what users are reading, instead of relying on tracking individuals. Its revenue comes from advertiser spend.
Cookieless contextual advertising that uses AI to read content and place brand ads where they are relevant, sold to brands and agencies. This is the model Advia's founders took from Seedtag and applied to search, video and AI assistants.
Sells machine-learning ad performance to advertisers: its models predict where and when an ad will convert. Advia's Vera engine does the same kind of prediction.
Contextual advertising platform that uses AI to understand content across web and video and target ads without cookies or personal data. Revenue comes from brand campaigns.
