Idea and Searching × Value

Before optimizing anything, find a segment that needs the product badly enough to come back. Run the PMF survey by segment, switch interviews and the itch finder, study the few habitual users, and narrow to the people who love it.

M0-M1 × Value

The playbook

Goal. Confirm that someone needs the product before improving engagement. Game layers can't rescue a weak core.

Diagnose. The PMF survey with segment analysis (who benefits most, the main benefit, what to improve); switch interviews with adopters and churners F07; the itch finder, asking "why" down to an emotion HK-T04 (Hooked Ch.2); and, if a handful of users already come back on their own, what they have in common (Habit Testing's Codify step) HK-MEA03 (Hooked Ch.8).

Moves. Narrow to the segment that loves it. Remove what that segment doesn't use HK-ACT43 (Hooked Ch.8). Let more people reach the core value before registering HK-ACT40 (Hooked Ch.7). Split the roadmap between what lovers value and what blocks near-lovers who share the main benefit.

Exit. A segment at or above 40% "very disappointed" (a heuristic, directional from about 40 answers) and a flattening retention curve for that segment.

KPIs. PMF score by segment (primary); curve shape (diagnostic); n per segment (guardrail on the claim).

    Itch finder: ask why until a feeling appears

    find the feeling behind the use

    Find the internal trigger by studying what users feel just before they act. Write a short story of that moment, then keep asking why until a feeling shows up, such as boredom, loneliness, frustration, confusion, indecision or fear. Check the answer against observed behavior, not survey replies.

    Set a realistic cadence for a devoted user, count the share of each signup cohort who meet it, and compare what those users did in their first days with users who left. The book's rule of thumb: below about 5% habitual, you have the wrong audience or a product to rethink.

Not now

  • Scale paid acquisitionPaid traffic into a product that doesn't keep people yet just fills a leaky bucket.
  • Points and badges layerPoints bolted onto a weak loop don't hold people.
  • Streaks with freeze and repairStreaks reward coming back to something people don't value yet.
  • Small copy or button A/B testsAt your volume a small tweak would take months to read.
  • Annual-plan discountsLocking people in before the habit forms just delays the churn.
  • Hard paywall before the habitA paywall before the habit converts some and loses the rest.
  • Two-sided referral programReferral programs amplify love that isn't there yet.
  • Near-peer leagues (leaderboards)Leaderboards need a dense community to feel fair.
