What’s an assumption?

An assumption is something we believe is true without having proof. In product discovery, assumptions can shape the direction of what we create. For example, you might assume people want a new app to track their fitness because you’ve noticed a trend in health apps. But what if people actually want something simpler, like a daily reminder to stay active? If you build based on your assumption without testing it, you could miss what users really need. That’s why assumption testing is important. It helps you check if your ideas match what users actually want before moving forward.
