Value hypothesis
Your best guess at who gets meaningful value from your idea and why. One sentence: "[segment] will [action] because [pain] costs them [consequence]." It's the claim every move is trying to break or confirm.
Beachhead segment
The narrowest group where you could plausibly win first. It is small enough to be homogenous enough to share a trigger and a workaround. Broad markets come later; you land on a beach, not a continent.
Disconfirmation
Evidence that your hypothesis is wrong. Actively seeking it — rather than only collecting agreement — is how you avoid building something no one needs.
Signal vs. noise
Signal is behavior: what someone actually did, paid, or built a workaround for. Noise is opinion: "sure, I'd probably use that." Score weights signal much higher.
Workaround
How someone solves the problem today, even if imperfectly. A real workaround proves the need for your product. No workaround usually means less need.
Pivot
Changing your product, service, or go-to-market strategy based on what you've learned about customers. A well-timed pivot on strong disconfirming evidence scores as well as a validated bet.
