Independent editorial profile
Product and growth writer, podcaster, and investor
Lenny Rachitsky publishes deeply researched product, growth, AI, and career advice and hosts long-form conversations with experienced technology operators.
BuildOS listens to Lenny because his show gives experienced operators room to explain a framework, its examples, and its limits. In the current gallery he is the publishing host for two source episodes, not the originator of the guests' frameworks. We preserve that distinction and independently evaluate what becomes a skill.
