#78 Designing Sustainable Affiliate Partnerships | Nancy Harnett, Head of Affiliate Marketing at HubSpot

In this episode, Nancy Harnett, Head of HubSpot’s Affiliate Marketing Program, shares how they transformed their strategy to achieve 2x ROI. By shifting from a broad partnership model to a highly personalized, one-on-one approach, HubSpot was able to build stronger collaborations and drive better performance. She highlights the importance of prioritizing key partners, offering tailored support, and using data-driven testing and rapid iteration to optimize the program. Instead of flat-fee structures, HubSpot focuses on performance-based incentives and treats partnerships as strategic investments, similar to marketing or HR functions. Nancy also discusses the company’s powerful tech stack, including HubSpot CRM, Impact, PartnerStack, and AI tools, while emphasizing the need for compliance, fraud prevention, and a customer-centric approach. She explores underutilized partner opportunities, outlines a realistic one-year timeline for building a successful affiliate program, and shares valuable book recommendations such as Nudge and Atomic Habits.
