Head of Membership & Growth
Fractional, Part-Time (3 days/week) · AgenticAdvertising.org
The Opportunity
AgenticAdvertising.org (AAO) is the industry consortium governing AdCP (the Ad Context Protocol), the open standard for how AI agents buy and sell advertising. Founded by the brands, agencies, publishers, and platforms shaping the industry, AgenticAdvertising.org is where the future of advertising gets defined.
We already have strong momentum — a growing membership base, council member seats filling fast, and a healthy inbound pipeline of organizations wanting to join. What we need now is someone who can turn early traction into a movement — deepening engagement, accelerating growth, and building something lasting.
This is a fractional, part-time role (3 days/week) reporting to the Executive Director. Location is flexible, including non-US.
Note: During AAO's search for a permanent Executive Director, this role reports to Ben Masse, interim President of the AAO Board.
What You'll Own
You'll own the full membership lifecycle — with a warm pipeline, strong inbound, and a community already taking shape. Your job is to build on that traction, and then make sure every member gets so much value they become an evangelist.
Member Engagement & Value Creation
- Own the member experience end-to-end: onboarding, engagement, retention, and expansion
- Ensure members are actively participating in working groups, councils, events, and education programming — not just signed up
- Drive adoption of AAO programs within member organizations (e.g., rolling out AdCP Academy across a member's entire team)
- Continuously gather feedback and refine the membership value proposition based on what's actually landing
- Leverage Addie, AAO's agentic assistant (embedded across the website and Slack community), to automate onboarding, surface engagement insights, and enhance the member experience
Growth & Pipeline
- Organize and manage the existing membership pipeline — prioritize, follow up, and convert
- Accelerate new member acquisition at all levels, from individual memberships through council Leader-level sponsors
- Drive outreach to prospective members across brands, agencies, publishers, and technology/data platforms
- Partner with the Board, founding members, and strategic advisors to turn warm introductions into closed memberships
- Proactively identify and pursue new prospects beyond the existing pipeline
Sponsorship & Expansion
- Convert existing members into deeper commitments — council sponsorships, Leader-level memberships, and expanded organizational participation
- Help shape and sell new membership tiers and sponsorship packages as AAO's programming evolves
What Success Looks Like
Success here isn't measured in quotas — it's measured in value created. We're looking for someone who gets equally excited to ring the bell for a new member and to convince an existing member to roll out AdCP Academy to all their employees.
- Within 90 days: Existing pipeline organized and actively managed. Onboarding process streamlined. Clear picture of member engagement levels across the base.
- Within 6 months: Measurable acceleration in new member joins. Deepened engagement with existing members — more active participation in working groups, councils, and education programs. At least one meaningful upsell or expansion win.
- Ongoing: A membership experience that members actively promote. A repeatable rhythm for engagement, feedback, and growth. A growing community where every member feels the value.
Who You Are
- Equal parts relationship builder and closer — you care as much about retention as you do about closing
- Experience in sales, business development, or account management in ad tech, martech, or SaaS
- Strong network across brands, agencies, publishers, and platforms
- Experience selling memberships, partnerships, or enterprise solutions — ideally in a community or ecosystem context
- Self-starter who thrives with high autonomy, energized by building something from the ground up
- Excited about what AI agents mean for advertising — you don't need to be an engineer, but you need to be genuinely curious about where the industry is going
