Lenny's Newsletter distilled its members-only Slack into one edition covering five concrete practice areas for product leaders: differentiating behaviors of great PMs, a head-to-head comparison of Claude versus ChatGPT for product work, surviving brutal feedback in the first two weeks on a job, and a tactical guide for joining a pre-product-market-fit startup.
The Claude versus ChatGPT breakdown is the sharpest section. Community members tested both on real PM tasks and reported specific use cases where each model wins. That alone is worth the read if you are choosing your default tool. The pre-PMF startup section is equally direct: practitioners share what they wish they had known before joining early-stage companies, with no survivorship bias filtered out.
The full piece is behind a subscriber paywall, but the original is worth finding because the community-sourced format means the advice comes from practitioners who are in the work now, not retrospective case studies. The hard-feedback scenario, two weeks into a new role, is the kind of specific situation most PM writing ignores entirely.
