Why lenny's newsletter fits product work
Core concepts that matter
Newsletter and essays
Weekly (or near-weekly) long-form posts. Topics: prioritization, OKRs, PLG, onboarding, hiring, managing up, and “how X company does Y.” Use the archive and search when you’re working on a specific theme.
Lenny's podcast
Interviews with product and growth leaders. Often 1–2 hours. Good for commutes or background; you can skim show notes if you’re short on time. Many episodes tie to newsletter themes (e.g. retention, pricing, org design).
Living library and community
Curated links and discussions for subscribers. Use them to find “best post on X” or to ask questions and get peer and sometimes Lenny’s input.
Topics that show up often
Prioritization and roadmaps - RICE, outcome vs. output, “how we decide what to build.” Growth and retention - Activation, retention curves, expansion revenue. Hiring and teams - What to look for in PMs, how to run interviews, org structure. Career - Transitioning into PM, moving to leadership, negotiating offers.
