Client Success Manager

We're looking for a Client Success Manager to join our team in New York 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.


Your Challenge

As Senior Client Success Manager , you will:

• Own and grow a portfolio of Seedtag's most strategic accounts, acting as the senior trusted advisor and lead point of contact for key clients and agency partners across the East Coast business.
• Design and lead "Next Best Action" strategies during campaigns that leverage upselling opportunities to improve performance - new products, channels, audience targeting, and beyond.
• Drive account growth and retention, consistently achieving and exceeding quarterly incremental revenue goals for key accounts, with campaigns tracking to >90% KPI attainment across your book of business.
• Initiate and oversee end-to-end execution of client campaigns in partnership with the Ad Operations team, ensuring delivery against agreed timelines, budgets, and client objectives.
• Ensure clients receive regular, detailed campaign performance reports as per their preferences (e.g., weekly, monthly), translating data into actionable insights, strategic recommendations, and opportunities for future investment.
• Lead regular client performance reviews and strategic conversations, providing clear reporting, insights, and recommendations tailored to each client's business objectives, and mentor junior Client Success Managers on account strategy and client management best practices.
• Conduct post-campaign analysis within one week of campaign completion to identify learnings, optimization opportunities, and strategies to strengthen future campaigns.
• Anticipate risks and take ownership of resolving complex client or campaign challenges, coordinating with internal teams and escalating to senior management or Ad Operations only when necessary, with a clear summary of the problem and solutions attempted.
• Chair regular meetings with Sales, Ad Operations, Insights, and other cross-functional stakeholders to align on account strategies and maximize the potential of key clients.
• Maintain accurate account information, opportunities, and client activity across Salesforce and other internal tools (e.g., Slack, Jira), and uphold a consistently high customer satisfaction score across your portfolio.

What You'll Need to Succeed

• 4-6+ years of experience in Customer Success, Account Management, digital advertising, AdTech, media, or a similar client-facing role.
• Proven track record of managing and growing strategic accounts, driving client retention, upselling, and incremental revenue.
