Senior Publisher Partnerships Manager

Since 2018, we’ve been reshaping programmatic advertising to make it faster, more transparent, and more profitable by building the most direct path between publishers and advertisers.
But we don’t stop here: wherever attention lives, on the web, in apps, on CTV, and beyond, our mission is to monetize audiences, across every device. Our data-driven tech delivers 30% higher revenues for our clients on average than traditional solutions.

Behind Sparteo’s growth is a team of 100+ talents across 11 countries, united by a shared ambition to redefine the future of digital advertising, and we are now expanding in North America.

Our dedication has placed Sparteo among the most dynamic tech players in Europe:

• FT1000 ranking: Among the fastest-growing European companies in 2024 & 2025

• The Europas: Featured in the list of 100 hottest startups

• Pixalate Ranking: #1 Web SSP in France, overtaking Google AdExchange

These milestones are just the result. What truly sets us apart is how we work: at Sparteo, we don’t settle, we act.

• We are Drivers, not passengers: We take the wheel and own our results.

• We are data-obsessed: Facts guide us, not assumptions, not egos.

• We think as one: Collective goals come before personal wins.

• We trade off: We simplify, prioritize, and go for high-impact results.

• We solve problems: We own challenges and turn ideas into action.

• We say what we do: Radical transparency is how we grow, no fluff, no hiding.

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.

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).

• 🚀 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.

• 🗽 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.

At Sparteo, we believe diversity is a strength. We are committed to providing equal opportunities and fostering an inclusive work environment. We encourage applications from all backgrounds, identities, and experiences.
