Senior Publisher Partnerships Manager

Your Job Your mission is to build Sparteo's publisher business on the US East Coast by winning the independent premium and mid-market publishers (Tier 2) that the big platforms overlook. You use your network, your credibility and your hunting skills to identify high-potential publishers, convince their decision-makers to upgrade their monetization, and close exclusive monetization partnerships with Sparteo. As one of our first senior sales leaders in the US, you also help shape how we grow: which segments we prioritize, how we position Sparteo against established players, and how our North American supply team scales. Strategic Prospecting & Network Activation • Hunt for high potential: map the US web to find independent publishers, vertical and niche media, regional outlets and digital-first brands (Tier 2) that are under-monetized or poorly served by their current partner. Think beyond New York: the Northeast, the Southeast and the Midwest have a rich and underexploited publisher landscape. • Activate your network: open doors through the relationships you have built with publisher owners, founders and revenue leaders, and turn them into a qualified pipeline. • Smart qualification: quickly assess a publisher's ad stack, traffic quality and revenue potential (SimilarWeb, BuiltWith, ad stack analyzers) to focus your energy on the accounts with the strongest upside. • Pipeline ownership: build and maintain a robust, predictable pipeline, with rigorous forecasting against ambitious revenue targets. Executive Selling & Closing • Sell to decision-makers: engage CEOs, founders, CROs and Heads of Revenue, and position Sparteo as a strategic monetization partner rather than one more vendor. • Make complexity simple: translate header bidding, consent, page experience (Core Web Vitals) and yield into a clear business case, and show publishers what they leave on the table today (Sparteo delivers +30% RPM on average). • Structure exclusive partnerships: lead negotiations on long-term agreements, focusing the discussion on value and revenue uplift, and work with Legal on contractual terms. • Fast time-to-revenue: coordinate seamless handoffs with our Account Management and Ad Operations teams so that every new partner sees results quickly. Market Intelligence & US Playbook • Feedback loop: bring structured insights on US publisher needs, objections and market specifics to our leadership and Product teams (state privacy laws and GPP, the weight of managed-service networks, CTV and video adoption). • Competitive edge: know the managed-service and monetization players active with US Tier 2 publishers (such as Mediavine, Raptive, Ezoic, Freestar, Playwire), and master the arguments to displace them. • Shape the playbook: help define our US go-to-market, share best practices with the West Coast team, and contribute to structuring our North American supply business as it grows. Your profile for this job Must Have: • 10+ years in ad tech or digital media sales on the publisher side, with a proven track record of closing and growing publisher partnerships in the US. • An established network among US Tier 2 publishers (independent premium, mid-market, vertical and niche media), with real decision-maker relationships. • Experience selling exclusive or managed-service monetization solutions, beyond plain non-exclusive SSP integrations. • Executive presence and negotiation skills: you are credible with publisher owners and C-level, and you know how to structure and close long-term partnerships. • Hunter DNA: you open new accounts, handle objections and keep closing, with the seniority to run complex deals on your own. • Based in the New York area, and ready to travel to meet publishers. Should Have: • Solid understanding of programmatic mechanics: header bidding, SSPs, ad servers, yield and consent management (GPP, US state privacy laws). • Strong analytical mindset: you build data-backed business cases (RPM uplift, traffic analysis, yield comparison). • Experience in a fast-growing ad tech company or a market launch, where you had to build rather than inherit a book of business. • AI-native reflex: you use AI tools every day to research, prepare and scale your sales activity. Could Have: • Experience selling video monetization or CMP / consent solutions as part of a broader stack. • Knowledge of CTV and in-app monetization trends in the US. • Experience coaching or mentoring other sellers, with the appetite to take on a broader supply leadership role in North America over time. • Familiarity with tools like SimilarWeb, BuiltWith or ad stack analyzers. • French is a plus (not required). Your mindset to share our adventure • You want to make an impact and move things forward collectively, building on what works and questioning what can be improved. • 🧠 You solve problems pragmatically and analytically. • You're looking for a fast-moving environment where your agility will be an asset. The 80-20 (Pareto) principle holds no secrets for you. • 🎧 Your ability to listen encourages you to challenge and improve yourself on an ongoing basis. What We Offer • 🗽 New York based, flexible: work from home and on the road, close to your publishers. • Ground-floor opportunity: join our US expansion early and help build our North American supply business. • International team: collaborate with teams across Europe and North America. • AI at your fingertips: Claude is made available to every team member, within our AI usage policy. • 🩺 Benefits: health insurance, pension plan and life insurance.
