Distinguish “people like this feature” from “people choose this product.” Trace how a buyer or user weighs the whole product, switching effort, trust, timing, price, and alternatives before deciding to adopt.

Use what you learned in the previous lesson to solve real-world problems.

Identify why one impressive sale, pilot, or customer win does not equal PMF. Look for a repeatable pattern across similar customers who buy or use for similar reasons without heroic one-off effort.

Contrast launch excitement with durable market pull. Recognize signals such as continued usage, referrals, renewal, expansion, and inbound demand that matter more than press, signups, or demo-day applause.

Use what you learned in the previous lesson to solve real-world problems.

Reason through the business side of PMF: customers must be reachable, willing to pay enough, and serviceable without destroying margins or team capacity. See why user love alone is not enough if growth economics do not work.

Define PMF for a specific customer segment, use case, and buying situation rather than for “the market” in general. Practice narrowing vague traction into the exact group where the product is becoming a must-have.

Use what you learned in the previous lesson to solve real-world problems.

Treat PMF as an evidence-backed condition, not a certificate earned once. Learn why fit can be partial, strengthen over time, or disappear when competitors, customer needs, pricing, channels, or product quality change.

Check what you understood with a short quiz.

Sort common PMF claims by evidence strength: compliments, feature requests, waitlists, trials, paid adoption, retention, and profitable growth. Use the evidence ladder to avoid mistaking early interest for a repeatable market match.
