Seedtag is a Madrid advertising technology company founded in 2014 by two former Google employees. Its contextual advertising engine reads the meaning of articles and images to place ads without using personal identifiers. The company operates across Europe and the Americas and is a reference in cookieless advertising.

We’re looking for an Junior Exchange Product Manager to join our team in Madrid and play a key role in shaping the future of neuro-contextual advertising at a global scale.

Who We Are

Seedtag is the leading Neuro-Contextual Advertising Company.

We are redefining how advertising works in a privacy-first world by moving beyond keywords and cookies, towards understanding human emotion, intent, and context.

Powered by advanced AI and neuroscience, our proprietary technology, Liz, delivers a deep, human-like understanding of content and attention. This enables brands to connect with audiences at the right moment, in the right mindset, with ads that are relevant, engaging, and respectful of the user experience.

Founded in 2014 by two ex-Googlers, Seedtag has grown into a global company with 500+ Seedtaggers across 17 countries, backed by €250M in funding, and expanding rapidly across the open web and Connected TV.

We’re not just building technology, we’re rewriting the rules of advertising.
