Relationship-Driven Product Marketing: Building Influence and Trust with Tamara Grominsky

Product marketing is more than frameworks, messaging, and launches—it’s about people. At its core, success in PMM comes from relationships: the trust you build with product teams, the credibility you earn with sales, and the network you nurture across the industry. When your relationships are strong, your influence grows—and so does your impact.

In this episode of Porter’s Product Marketing Podcast, we’re joined by Tamara Grominsky, the Founder of PMM Camp and a product marketing leader with a rich background that includes leadership roles at Kajabi and Unbounce. With a master’s degree from Simon Fraser University and a bachelor’s from York University, Tamara has built her career around strategic storytelling, thoughtful influence, and one of the most undervalued superpowers in marketing: relationship management.

This conversation is a must-listen for anyone who’s ever felt like product marketing is stuck between teams—and is ready to turn that in-between space into a position of leadership. In this episode, you’ll learn: How to build and nurture strategic relationships as a PMM What it takes to earn trust—not just visibility—across cross-functional teams Why influence inside a company often matters more than authority How external networking can grow your career, your skill set, and your confidence Tactics for staying top-of-mind and valuable across your internal and external networks How to manage and maintain authentic connections, even at scale Why this episode is worth your time: You can be the most strategic, technically skilled, and creative product marketer in the room—but if you can’t build trust and navigate relationships, your best work may never see the light of day.

Tamara shares real, practical insight on how to become a connector inside your organization: someone who brings teams together, communicates with empathy, and influences decisions early—before the positioning doc is even drafted. She also talks about how to expand your influence beyond your current role—by investing in meaningful industry relationships, sharing your thinking publicly, and finding your voice through networking that doesn’t feel transactional.

If you’re looking to have more strategic impact, get invited to the right conversations, and build a PMM career that opens doors—not just decks—this episode is packed with tools and mindset shifts to help you grow. Who this episode is for: PMMs looking to strengthen their internal influence and collaboration Product marketers struggling to gain traction with sales, product, or execs Marketing leaders coaching junior team members on stakeholder management Early-career PMMs looking to grow their external presence and industry network Anyone who wants to lead through trust, not titles
