Marketplace advisory & consulting
With nearly a decade in the marketplace industry, I've spoken with hundreds of founders and investors, analyzed top-performing marketplaces, and distilled their key ingredients into actionable strategies for early-stage marketplace growth.
I offer on-demand coaching, project-based support, and long-term advisory board roles.
