• Manage the campaign calendar and own the marketing tooling stack (HubSpot, Substack, social accounts).
• Keep reporting tight across application windows, track top-of-funnel metrics, conversion rates, and community growth.
• Leverage AI tools and automation to drive efficiency while maintaining a human-in-the-loop on all founder-facing channels.
