  3. Avoids unsupported claims44% pass
    Presents 'root cause: we've let the loudest requests set the roadmap' and 'SMB remains our top-of-funnel' as facts without labelling them as hypotheses or citing evidence.

How it’s graded

Each check is built on how world-class product and growth leaders do this work, as they’ve described it on Lenny’s Podcast, and names the leader it comes from.

  1. Diagnosis before prescription

    Does the strategy name the crux, the specific obstacle or opportunity the evidence points to, and do the proposed actions follow from that diagnosis?

    Passes when States one crux grounded in the supplied evidence, and each major action visibly addresses it.

  2. Names an advantage that's hard to copy

    Does the strategy say what will make its position hard for an informed, well-funded competitor to copy (a benefit customers value plus a barrier to copying it), rather than relying on being first, on features, or on funding?

    Passes when Names the benefit and the barrier, and why a capable competitor couldn't simply replicate it.

  3. Says what it gives up

    Does the strategy name what the company will stop doing, or deliberately not do, in order to pursue it?

    Passes when Names at least one real thing being dropped or declined, with the reason it loses out.

Read the brief, then compare up to three outputs, each with the LLM judge’s verdict on every check. Highlights mark what a PM had to fix.

The brief

Our tutoring marketplace has stalled at about 4,000 bookings a month. Write a one-page strategy for the next 12 months (about 500 words) for our CEO to take to the board. We can fund one major bet.

What the model was given4 items: Scenario, Metrics, Research, Board view
ScenarioTutorly connects secondary-school students with independent tutors for online lessons at £30–45 an hour; we take a 20% commission. There are 6,500 active tutors and 11,000 active students. We have 18 months of runway and about £1.2m to put behind the one bet.
MetricsTutor supply up 60% year on year; bookings up 8%. 70% of tutors get zero bookings in a typical month. Repeat booking rate is 64% for students who book twice.
ResearchStudents cite 'finding the right tutor' as their top problem. Tutors cite 'not enough students'.
Board viewThe board believes paid acquisition of students is the answer.
What a strong answer doesThe answer key the graders mark against

Recognise the contradiction: supply is abundant but matching fails, so buying demand into a broken match pours water into a leaky bucket. Choose matching quality and say what is given up.

Tutorly: 12-Month Strategy Board paper, for decision

The problem Bookings have grown 8% while tutor supply grew 60%. We are not short of tutors or students. We are failing to connect them. Students say their top problem is finding the right tutor. Tutors say they lack students, and 70% get no bookings in a typical month. Once a student books twice, 64% keep booking, so the product works when a match happens. The leak is in the first match.

Why not paid student acquisition The board's instinct is to buy more students. I recommend against it for now: - Paid students would arrive at the same broken search and matching flow that already frustrates them. We would be paying to acquire customers we are likely to lose before their second booking. - Our tutor base is already larger than our demand. More students would mainly bring more tutors into the same competition for the few bookings available. - Acquisition spend scales with cost. Matching improvements scale with use.

The bet: fix first-match conversion (£1.2m) Over 12 months we will build a guided matching system and test it against the current search:

  1. Structured intake (Months 1–4). Students give subject, exam board, year group, goals, budget, and availability. Required before search.
  2. Curated shortlists (Months 2–6). Within one hour, students receive three ranked tutors with a free 15-minute intro call. A small concierge team handles hard cases such as niche subjects and last-minute exam prep.
  3. Ranking that rewards fit and responsiveness (Months 3–8). Ranking weighs subject expertise, response time, and student outcomes. New tutors get guaranteed early exposure so that supply does not stall at the bottom.
  4. Tutor activation (Months 4–12). Tutors with zero bookings in 30 days receive coaching on profile quality and availability, plus targeted introductions.

Budget (£1.2m) - Product and engineering: £600k - Concierge matching team: £300k - Tutor activation and targeted student tests: £200k - Measurement and contingency: £100k

Targets (12 months) - Bookings: 4,000 → 5,500 per month - Students with a first booking within 7 days of intake: baseline in Month 1, target +50% - Share of tutors with at least one booking per month: ~30% → 45% - Repeat rate (second booking): hold at or above 64%

Decision gates - Month 3: Intake and shortlist live for a test cohort. Confirm the conversion baseline and the uplift. - Month 6: If first-match conversion has not improved by at least 20% against control, stop further build and move remaining funds to a small, controlled paid-acquisition test. If it has, scale the concierge model and begin targeted acquisition in segments where our supply is deepest. - Month 9: Review unit economics. Each booking should contribute enough commission to cover concierge cost.

Runway This plan spends £1.2m over 12 months and leaves about six months of runway for the gates above. If the Month 6 gate fails, we retain the option to pivot without running out of cash.

What we are asking the board to approve 1. Fund the £1.2m matching-led plan. 2. Approve the Month 6 gate and the reallocation rule if it fails. 3. Defer paid student acquisition until conversion data supports it.

The board's instinct is right that growth needs more students. But we already have more tutors than we can match, and the evidence points to the match as the bottleneck. Fixing that first makes every future pound of acquisition work harder.

The output invents a fact about not tracking conversion cleanly and presents several interpretations as established facts, so a PM would need to re-check evidence and correct unsupported claims before using it.

Tutorly: 12-Month Strategy

Sep 24, 2026 · @Martin Slaney

The problem is matching, not demand1

Tutor supply grew 60% last year; bookings grew 8%. 70% of our 6,500 tutors get no bookings in a typical month, and our 11,000 active students generate only \~4,000 bookings a month. Both sides report the same failure from opposite ends: students can't find the right tutor; tutors can't find students. Adding supply has made the catalogue bigger and choosing harder.

The bright spot: students who book twice repeat at 64%. The relationship works once it starts.3 The leak is between arriving and the second lesson.

Why paid acquisition first is the wrong bet

Paid acquisition sends more students into the same funnel that already fails to convert most of the ones we have. We'd be buying students at full cost and losing them at the step before the relationship forms. At a 20% take on £30–45 lessons (\~£7.50 per booking), we only recover acquisition cost from students who stick; today too few get there. Fix conversion first, and every pound of acquisition afterwards is worth more.

The bet: managed matching

Replace browse-and-hope with matching we take responsibility for.

  • Guided intake. Subject, level, exam board, goals, learning style, budget, availability. Two minutes, not twenty profiles.
  • We recommend three tutors, ranked on fit and track record, not on who signed up most recently.
  • Low-risk first lesson. A discounted trial plus a "right tutor or your next lesson free" guarantee.
  • Curate supply. Stop broad tutor recruitment. Recruit only where demand outstrips supply (by subject and exam level); rank and surface tutors on conversion and repeat rate; move inactive tutors out of results.
  • Start with human matchers, then automate what works. The concierge data trains the algorithm.

Budget and milestones

Allocation£
Matching product, data and ranking (team of \~4)500k
Human matching concierge (pilot, then scale down)200k
Trial-lesson subsidy and guarantee150k
Gated acquisition tranche (released at month 6 only if targets hit)350k
Total1.2m

Month 3: matching live for new students in top 3 subjects. Baseline set for first-to-second-lesson conversion (we don't track this cleanly today2; it's the number that matters most).

Month 6 gate: first-to-second conversion up 50% on baseline; share of tutors with zero bookings below 55%. Hit it, and we release £350k into paid acquisition, now into a funnel that converts. Miss it, and we hold the cash as runway.

Month 12: 6,000 bookings a month (+50%), with growth coming from bookings per student, not student count alone.

Ask of the board

Back matching as the one bet, with acquisition as its reward, not its substitute. We're not against growth spend; we're against spending it before the product can hold the students it buys. With 18 months of runway, the month-6 gate gives us a clear read while two-thirds of the budget and a year of runway remain.

What a PM had to fix

  1. 1Hypothesis stated as factReframe it as a hypothesisTargeted repair

    Source: ResearchStudents cite 'finding the right tutor' as their top problem. Tutors cite 'not enough students'.

    What we’d changeFrame matching as the working hypothesis the research points to, and say what the first months will test, rather than stating it as the diagnosis.

  2. 2Invented evidenceVerify or remove the claimQuick edit

    What we’d changeRemove it: the brief doesn't say what's tracked. Say the baseline will be set in month 3.

  3. 3Hypothesis stated as factReframe it as a hypothesisQuick edit

    Source: MetricsRepeat booking rate is 64% for students who book twice.

    What we’d changeThe 64% applies to students who book twice. It doesn't show the relationship works for everyone who starts.

Claims the judge couldn’t find in the brief

  • today too few get there [students who stick]
  • we don't track this cleanly today [first-to-second-lesson conversion]
  • The relationship works once it starts.
  • Adding supply has made the catalogue bigger and choosing harder.
  • The leak is between arriving and the second lesson.

Where they differ 3

Uses the supplied evidence correctlyMixedWrong
Haiku 5.5 · API

All factual statements about the current situation appear in the brief or context, or follow from the supplied numbers.

Opus 5.5 · Claude

The output states as fact that 'we don't track this cleanly today' and presents interpretations like 'The relationship works once it starts' and 'today too few get there' as established facts, none of which appear in the supplied context.

Avoids unsupported claimsMixedWrong
Haiku 5.5 · API

Interpretations like 'not short of students' and 'leak is in the first match' are grounded in the supplied evidence and not presented as unsupported assertions.

Opus 5.5 · Claude

Interpretations like 'The relationship works once it starts', 'The leak is between arriving and the second lesson', and 'today too few get there' are presented as confident facts without being labelled as hypotheses.

Proposes tests that could failWrongRight
Haiku 5.5 · API

The Month 3 gate lacks a numeric threshold, does not specify what result would stop or continue, and thus doesn't fully meet the 'test that could fail' requirement.

Opus 5.5 · Claude

The month-6 gate has numeric thresholds (conversion up 50%, zero-booking tutors below 55%), a 3-month measurement window, and clear actions for pass (release £350k) and fail (hold cash).

All got wrong 1

Names an advantage that's hard to copyWrongWrong
Haiku 5.5 · API

Does not name a benefit customers value plus a barrier that would make the position hard for a well-funded competitor to copy.

Opus 5.5 · Claude

The strategy does not name a benefit and a barrier that would make the position hard for a well-funded competitor to copy; it mentions human matchers and data training but never explains why a competitor couldn't replicate it.

All got right 8

Addresses the actual decisionRightRight
Haiku 5.5 · API

Commits early to matching as the one bet, defers paid acquisition, and names the Month 6 conversion improvement condition that would change the answer.

Opus 5.5 · Claude

The output commits early to 'managed matching' as the one bet, frames it for the CEO/board, and specifies that missing the month-6 gate would change the call (hold cash as runway).

Respects explicit constraintsRightRight
Haiku 5.5 · API

Delivers a ~500-word one-page board paper that respects the single-bet budget and runway.

Opus 5.5 · Claude

The output is a one-page strategy of about 400 words, addresses the CEO for the board, and funds one major bet (matching) with a conditional acquisition tranche, respecting the brief's constraints.

Identifies material uncertaintyRightRight
Haiku 5.5 · API

Month 6 gate sets a clear numeric threshold and action; the plan acknowledges the risk and a pivot option if the bet fails.

Opus 5.5 · Claude

It names the unknown first-to-second-lesson conversion rate, says it will set a baseline, and uses a month-6 gate with numeric thresholds to resolve whether to release acquisition spend.

Produces the required deliverableRightRight
Haiku 5.5 · API

Output is a complete board-ready paper within the length, formatted for the CEO to take to the board and act upon.

Opus 5.5 · Claude

The output is a complete one-page strategy memo for the CEO to take to the board, within the requested length, and is usable with light edits.

Surfaces the central contradictionRightRight
Haiku 5.5 · API

Explicitly states that supply grew 60% while bookings grew only 8%, highlighting the disconnect that the matching bet addresses.

Opus 5.5 · Claude

It explicitly notes that tutor supply grew 60% while bookings grew only 8%, surfacing the contradiction that supply growth hasn't produced bookings.

Makes a clear choiceRightRight
Haiku 5.5 · API

Chooses the matching bet and clearly defers paid student acquisition, naming what is given up.

Opus 5.5 · Claude

The strategy chooses managed matching as the one bet and names what it forgoes: immediate paid acquisition and broad tutor recruitment.

Diagnosis before prescriptionRightRight
Haiku 5.5 · API

Diagnoses the first-match conversion as the crux and then proposes structured intake, curated shortlists, ranking, and tutor activation that all address it.

Opus 5.5 · Claude

It diagnoses the crux as a matching failure between arrival and the second lesson, and all major actions (guided intake, recommendations, trial guarantee, supply curation) directly address that crux.

Says what it gives upRightRight
Haiku 5.5 · API

Explicitly defers paid student acquisition, naming the sacrificed growth lever and the reason (conversion data needed first).

Opus 5.5 · Claude

It explicitly says to stop broad tutor recruitment and defers paid acquisition, naming real things being given up with the reason they lose out.

Strategy that doesn't choose isn't strategy. Models write fluent strategic prose easily; making a choice the evidence supports and naming what it gives up is harder.

What good looks like

  • Diagnoses the one obstacle that matters before prescribing
  • Makes one clear choice and names what is sacrificed
  • Grounds the choice in the supplied evidence
  • Surfaces the tension or contradiction in the data
  • Defines how we would know it is working
