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.

• Campaign Performance & Excellence: Ensure the team delivers successful advertising campaigns, meeting client objectives, performance KPIs, and operational standards in collaboration with Ad Operations.

• Data-Driven Strategy: Establish and monitor key Client Success metrics, using campaign performance, client feedback, and business insights to identify opportunities and improve results.

• Cross-Functional Leadership: Partner closely with Sales, Ad Operations, Insights, and other regional and global stakeholders to align commercial strategies, resolve challenges, and improve the client experience.

• Process Optimisation: Identify opportunities to improve workflows, reporting, account management practices, and team efficiency, ensuring scalable Client Success operations across the region.

What You’ll Need to Succeed

• 8+ years of experience in Client Success, Account Management, digital advertising, AdTech, media, or related client-facing roles.

• Proven people management and leadership experience, including coaching, developing, and managing high-performing Client Success or Account Management teams.

• Strong track record of driving client retention, account growth, upselling, and incremental revenue across strategic accounts.

• Deep understanding of digital advertising and programmatic, including campaign strategy, performance measurement, DSPs, SSPs, and the broader AdTech ecosystem.

• Established relationships with agencies, advertisers, and key stakeholders in the North American advertising market.

• Experience defining and managing team KPIs, revenue targets, client satisfaction metrics, and operational performance.

• Strong strategic and commercial mindset, with the ability to translate business objectives into actionable Client Success initiatives.

• Excellent leadership, communication, negotiation, and stakeholder management skills, with experience influencing senior-level clients and internal stakeholders.

• Strong analytical and problem-solving skills, with the ability to use data to inform decisions, identify growth opportunities, and improve team performance.
