People are probably not using your product the way you think

Airpods are a great example of a product that flies off the shelves because users know exactly what the company does, what the product offers and are extremely satisfied with them. Photo by insung yoon on Unsplash.

Product market fit (PMF) is one of the hardest things to get right and it’s necessary for a startup to survive and thrive. Even scale-ups and established companies face PMF challenges as soon as they start growing into new markets and product categories. There has been a ton of great writing about how to know when you have PMF and structured approaches to measure and influence it (e.g. Super Human’s product market fit engine).
