Hitting product-market fit (PMF) at WorkOS was a transformative experience, marked by a surprisingly broad range of real use cases and the shift from straightforward "how-to" questions to strategic inquiries about enterprise adoption. The company's early success was fueled by its ability to make customers happy, with a usage-based revenue model that only charges customers when they're truly satisfied with the product. PMF is not just a static moment but an ongoing dialogue with users, and it requires continuous communication, iteration, and adaptation to remain relevant. Key takeaways include focusing on smaller, scrappier teams, making 10 initial customers truly love the product before scaling, tying revenue to usage, and maintaining a beginner's mindset to stay close to customers and continue innovating.
