What Product-Market Fit Feels Like - Alexandra Zatarain (Eight Sleep)

In this interview excerpt, Alexandra Zatarain explains how Eight Sleep recognized that it had achieved product‑market fit (PMF). She emphasizes that PMF is felt rather than seen purely in data, describing a shift from the early years where the company had to constantly devise new ways to generate revenue (the "pushing the boulder" phase) to a later period where the market pulls the product forward, creating a sense of alignment and compounding growth. Zatarain notes that early revenue spikes—such as press coverage or Product Hunt launches—can be misleading, as they do not sustain without true PMF. The narrative is framed as two distinct five‑year phases: the first lacking PMF, marked by struggle, and the second with PMF, marked by effortless demand and rapid growth.
