Where it slips

  1. Names an advantage that's hard to copy10% pass
    Does not name a benefit and a barrier that a well-funded competitor couldn't copy; no moat is identified.

  2. Proposes tests that could fail46% pass
    The operating targets for mid-market and SMB lack explicit actions if missed; only the enterprise gate specifies what each result triggers.

  3. Avoids unsupported claims54% 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.

The tasks

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.

Output

MEMORANDUM TO: The Board of Directors FROM: CEO, Tutorly DATE: October 24, 2023 SUBJECT: 12-Month Strategy: Unlocking Liquidity via Guided Matching

1. The Diagnosis: A Conversion Crisis, Not an Acquisition Crisis Tutorly has stalled at 4,000 monthly bookings, generating roughly £30,000 in monthly net revenue. While the Board has suggested deploying our £1.2m capital into paid student acquisition, the data indicates this would be a fatal mistake.

We do not have a top-of-funnel problem; we have a liquidity and matching problem. We currently have 11,000 active students on the platform, yet they generate only 4,000 bookings. Meanwhile, our tutor supply has grown 60% YoY to 6,500, leaving 70% of tutors with zero bookings a month.

Why are 11,000 active students not booking 6,500 available tutors? User research gives us the answer: students are paralyzed by the paradox of choice, citing "finding the right tutor" as their top barrier. Tutors think there aren't enough students, when in reality, bloated supply is actively hurting student conversion. Pouring £1.2m of paid marketing into a leaky bucket will only burn our 18-month runway faster.

However, our bright spot is retention: when a student books twice, their repeat rate is 64%. Our core strategic challenge is getting existing students from browsing to their second booking.

2. Our One Major Bet: "Tutorly Match" & Supply Curation Instead of buying traffic, we will invest our £1.2m in product-led conversion. We will pivot Tutorly from an open directory (like Craigslist) to a curated, algorithmically matched marketplace (like Uber).

Over the next 12 months, we will execute a three-part strategy:

  • Aggressive Supply Curation: We will freeze new tutor onboarding and delist the bottom 50% of inactive/low-converting tutors. By concentrating demand among the top 2,000 tutors, we instantly improve the average quality of a student’s first lesson and keep our best tutors earning and engaged.
  • The "Concierge" Matching Engine: We will replace our search bar with a diagnostic intake flow. Students will input their exam board, target grade, and learning style, and our algorithm will present only three ideal tutors.
  • The "Two-Lesson" Guarantee: Because a second booking triggers a 64% repeat rate, we will subsidize the friction of trial-and-error. If a student doesn’t click with their first matched tutor, Tutorly will fund the first lesson with a replacement tutor.

3. Capital Allocation (£1.2m) * £650k (Product & Data): Hiring a dedicated squad (PM, Data Scientist, 3 Engineers) to build the matching engine, diagnostic onboarding, and a revamped tutor rating system based on student retention. * £350k (The "Second Booking" Subsidy): Financing the "First-Match Guarantee" and discounting a bundled "First Two Lessons" package to force the habit loop. * £200k (Lifecycle Marketing): Automated CRM flows (SMS/Email) to re-engage the ~7,000 dormant students currently on our platform.

4. 12-Month Success Metrics By fixing the conversion bottleneck first, we build a machine that can profitably scale paid acquisition in Year 2. By Q4 next year, this bet will deliver: 1. Bookings: Increase from 4,000 to 12,000/month (tripling net revenue to ~£90k/month). 2. Student Activation: Increase the percentage of active students reaching their 2nd booking from ~15% to 40%. 3. Marketplace Health: Reduce the "zero-booking" tutor rate from 70% to under 20% (on a curated base of 2,500 tutors).

Claims the judge couldn’t find in the brief

  • ~7,000 dormant students currently on our platform
  • current percentage of active students reaching their 2nd booking is ~15%
  • students are paralyzed by the paradox of choice
  • bloated supply is actively hurting student conversion

Check by check

Open a check to read the judge’s reasons. “Mixed” means the two graders disagreed.

Got wrong 5

Uses the supplied evidence correctlyWrong

Contains invented current data (7,000 dormant students, ~15% student second-booking rate) not supported by the brief or context.

Addresses the actual decisionWrong

Does not state what result or condition would change the chosen bet.

Identifies material uncertaintyWrong

Does not name specific unknowns that could change the decision or how they would be resolved.

Avoids unsupported claimsWrong

Presents causal interpretations ('paralyzed by paradox of choice', 'bloated supply is actively hurting student conversion') as established fact without labelling them as hypotheses.

Names an advantage that's hard to copyWrong

Does not name a specific customer benefit and a barrier to copying; pivot to curated matching is described without explaining why it's defensible.

Mixed 1

Diagnosis before prescriptionRight

States crux as matching/conversion problem, and all major actions (curation, matching engine, two‑lesson guarantee) address it.

Says what it gives upRight

States what is given up: paid student acquisition and new tutor onboarding/delisting inactive tutors.

About the task

The PM job

Writing a strategy memo that leadership can act on.

Why it matters

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

Deliberately not measured

  • Market sizing accuracy beyond the supplied data
  • Financial modelling
Capability tested
