"PMF Kit transformed how we validate product-market fit. Instead of wandering through vague user research, the /pmfkit.pmf workflow forced us to define personas, jobs-to-be-done, and success metrics upfront. We ran structured discovery interviews and had evidence-backed go/no-go decisions in weeks, not months. Spec-driven development isn't just for codeβ€”it's an operating system for any knowledge work."
