Product Manager - Sponsorships

Substack helps independent writers, podcasters, artists, and other creators build businesses around their work. The Product Manager will lead product for Substack Sponsorships, developing sponsorship formats, advertiser and publisher tools, and the foundations of a scalable marketplace while partnering across Engineering, Design, Data, Partnerships, and the Sponsorships business team.

Responsibilities:

• Set the product direction. Use conversations with publishers and advertisers, product data, and company priorities to build a roadmap across near-term experiments and longer-term platform work. Turn lessons from early campaigns into products that work across thousands of publications
• Build distinctive sponsorship experiences. Develop formats that fit naturally into Substack across email, web, and app, including sponsorships that help readers discover writers, access paid work, and become subscribers
• Own the advertiser experience. Make it easy for brands and agencies to discover relevant publications, plan and book campaigns, manage creative approvals, and understand results. Build the path from managed campaigns to self-service buying
• Make sponsorships work for publishers. Create simple tools to opt in, set preferences, approve opportunities, manage placements, and track earnings. Preserve publishers’ control over which brands they work with and how sponsorships appear in their work
• Build the marketplace and operating foundation. Partner with Engineering and Ad Operations on matching, inventory forecasting, campaign delivery, pacing, billing, and payouts. Decide what to build and where external technology or demand partners can accelerate progress
• Prove advertiser value and product impact. Own the measurement roadmap across delivery, reach, engagement, brand lift, and conversion outcomes. Define success metrics, dashboards, and experiments with Data and measurement partners, while respecting reader privacy
• Balance growth with trust. Partner with Policy, Legal, and core Product on advertiser eligibility, sponsorship disclosure, data use, and ad quality. Evaluate revenue opportunities alongside their effects on reader experience and subscription retention
• Own execution and adoption. Partner with your Engineering counterpart to scope, prototype, and ship improvements. Work with the Sponsorships business team on launch plans, product education, and adoption, then use campaign results and customer feedback to decide what to improve next

• A strong understanding of how brands and agencies buy media, how publishers earn revenue, and how campaign delivery and measurement work
• Technical fluency across ad serving, data systems, APIs, and third-party integrations, with the judgment to choose practical solutions for an early-stage business

• High agency and clear written communication. You can make a persuasive case for a priority, write a useful product spec, and explain decisions to technical and commercial partners. You're willing to work through the details needed to get something shipped
