Jeff Su brings his characteristic clarity to one of the most misunderstood roles in tech: product marketing. Rather than recite a textbook definition, he walks through what PMMs actually produce and who they work with --- bridging product teams who build the thing, sales teams who sell the thing, and marketing teams who promote the thing. Jeff covers the launch lifecycle, explaining how PMMs drive the narrative from beta through general availability, and how they arm sales teams with the positioning, battlecards, and competitive intelligence needed to win deals. He also addresses the career side: how people typically enter product marketing, what the progression looks like, and why the role is increasingly seen as a pipeline to executive leadership. This is the video to share when someone asks "what do you actually do all day?" --- it's grounded, honest, and useful for anyone inside or outside the function.
