Explosive growth inspired by entrepreneurial courage.

Entrepreneurial courage motivates us. So when we learnt that Jorge Poyatos and Albert Nieto had left roles at Google to pursue their vision of reinventing digital advertising, we were impressed.

In 2016, we partnered with them to support Seedtag, then a 10-person company with a revolutionary idea: to build the world’s leading contextual advertising platform for a privacy-first web.

From bold idea to global category leader

Adara led the €1.5 million initial investment round and has remained closely involved ever since, helping shape Seedtag’s funding strategy, guiding its international expansion across 15+ countries, and supporting three strategic acquisitions that accelerated its growth and category leadership.

Seedtag’s founding insight was that advertising could be both effective and respectful, reaching audiences not through invasive tracking, but through a deep understanding of context. Its proprietary Contextual AI technology, LIZ©, interprets signals of interest, intent, and emotion to help brands engage consumers across premium CTV, video, and open web inventory. 

Today, Seedtag leads the industry in neuro-contextual advertising, delivering privacy-first, AI-powered campaigns at a global scale.

The most explosive growth we’ve been part of. Ever.

Since Adara’s first investment, Seedtag has achieved a compound annual growth rate of more than 2.3x, scaling from a startup in Madrid to a global company with over 600 employees across EMEA, LATAM, North America, and APAC.

In 2022, Advent International acquired a majority stake in Seedtag through a €250 million investment, one of the largest ever for a Spanish technology company.

A partnership built on vision, execution, and courage

We’re proud to have been Seedtag’s first institutional investor and to have accompanied Albert and Jorge every step of the way: from their early vision to their emergence as a global market leader.

Seedtag’s journey perfectly reflects Adara’s mission: to partner early with exceptional founders and help them build enduring, category-defining technology companies.


Seedtag is now the global leader in contextual advertising, helping brands deliver privacy-first, AI-driven experiences to consumers worldwide.
