Shannon Kearns joins host Justin Dorfman on #TheGTMPack to unpack what great product marketing really looks like across B2B and B2C, how to shift from sales-led to product-led growth without face-planting, and why behavioral psychology (not just copy) should drive your launches, claims, and lifecycle.

We also riff on Shannon’s spicy take that “AI is the new UI.”

What you’ll learn:

• The real B2B vs B2C differences: brand pillars, emotional promises, and claim-driven messaging

• PLG mindset shifts: experimentation discipline, XRDs (experiment reference docs), and data fluency

• Using internal product data to make credible, user-level claims (not just vanity stats)

• Behavioral psychology every PMM must know (paradox of choice, intent vs behavior, storytelling)

• Practical AI uses for PMMs today: competitor intel, persona GPTs, bias checks—plus where this is headed
