Achieving product-market fit (PMF) requires collaboration between product and go-to-market (GTM) teams throughout various stages of the PMF cycle. By aligning their efforts, these teams can leverage insights from both product development and market feedback, ensuring that products not only meet functional needs but also succeed commercially in a competitive landscape. Clear ownership of responsibilities is essential, as is recognizing the full unit involved in product creation, rather than attributing it to a single product manager.
