Case viewer

Read the brief, then put up to three outputs side by side, 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.

Needs more than a quick edit3 of 10 checks passed

A PM would need to remove invented current-state claims and add a hard decision gate and explicit sacrifice before using it. The reasoning is directionally strong but not evidence-safe as written.

Output

MEMORANDUM

TO: Board of Directors, Tutorly FROM: Chief Executive Officer DATE: October 2023 SUBJECT: 12-Month Strategic Plan: Unlocking Growth via Managed Matching

---

Executive Summary: Diagnosing the Growth Plateau

Our marketplace has stalled at 4,000 bookings/month (~£30k monthly net revenue) despite healthy user numbers (11k students, 6.5k tutors).

The Board’s instinct to deploy our £1.2m reserve into paid student acquisition is understandable, but premature. The data reveals a liquidity and conversion bottleneck, not an awareness problem: * Supply is bloated and disengaged: Tutor supply grew 60% YoY, yet 70% receive zero bookings monthly. * Friction kills discovery: Students cite “finding the right tutor” as their primary obstacle. Our open-directory model forces parents to sift through 6,500 profiles, causing decision paralysis and drop-off. * Underlying product-market fit is proven: When students reach a second booking, 64% retain.

Pouring paid traffic into an unguided directory will burn our £1.2m on high CAC and low conversion. Our single bet for the next 12 months is transitioning from an open directory to an intelligent, Managed Matching Engine.

The Single Bet: "The Perfect Match" Engine

Instead of browsing endless profiles, parents will complete a 60-second diagnostic intake (curriculum tier, personality, learning barriers, availability). Our matching engine pairs them with the single best tutor—backed by a 100% “First Lesson Satisfaction Guarantee” (rebooked free if not a fit).

By actively directing demand to a curated, high-performing top quartile of our supply (~1,500 tutors), we solve both sides of the marketplace: students find immediate trust, and active tutors earn dependable income.

#### Allocation of the £1.2m Capital: 1. Product & Matching Tech (£500k): Algorithmic intake flow, automated calendar sync, and in-app instant booking to eliminate messaging back-and-forth. 2. Onboarding & Operations (£300k): Quality vetting, tiering supply, and a proactive concierge team to manually rescue failed first sessions. 3. Targeted Performance Marketing (£400k): Phased acquisition deployed only once the match-to-book conversion rate improves.

---

12-Month Execution Roadmap

  • Q1–Q2 (Fix the Engine):
  • Replace public browse with the guided diagnostic matching flow.
  • Restrict active routing to the top 25% highest-rated tutors to concentrate liquidity.
  • Launch the "Fit Guarantee" to de-risk the first booking.
  • Q3 (Solve the 2nd Booking):
  • Automate recurring weekly reservation slots right after lesson one (optimizing for the 64% retention threshold).
  • Introduce 4-lesson starter packs to mathematically guarantee lesson two.
  • Q4 (Scale What Works):
  • Deploy the remaining £400k into intent-driven paid channels (Google Search for GCSE/A-Level revision), scaling into a proven, high-converting funnel.

Conclusion: Fixing search friction activates the high-retention engine we already possess. By funding matching instead of brute-force acquisition, we reach sustainable unit economics and double our run-rate within our existing 18-month runway.

Claims the judge couldn’t find in the brief

  • Tutorly currently operates an open-directory model in which parents sift through 6,500 profiles.
  • The current model causes decision paralysis and drop-off.
  • The problem is a liquidity and conversion bottleneck, not an awareness problem.
  • Paid traffic into an unguided directory will burn £1.2m on high CAC and low conversion.
  • There is a high-performing top quartile of supply of about 1,500 tutors.

Check by check

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

Got wrong 4

Uses the supplied evidence correctlyWrong

It invents current-state facts such as an open-directory model, parents sifting through profiles, decision paralysis, and a high-performing top quartile of about 1,500 tutors.

Identifies material uncertaintyWrong

It does not name material unknowns such as whether matching improves conversion, whether top tutors have capacity, or whether the guarantee is affordable.

Avoids unsupported claimsWrong

It presents several interpretations and forecasts as established fact, including high CAC, low conversion, decision paralysis, and guaranteed lesson two.

Proposes tests that could failWrong

The only gate, deploying paid marketing once match-to-book conversion improves, lacks a numeric threshold, measurement window, and explicit action for failure.

Mixed 3

Addresses the actual decisionMixed

It commits to managed matching, but does not clearly state what result or condition would change that decision.

Respects explicit constraintsMixed

It allocates £400k to paid acquisition as part of the plan without a concrete gate, so it does not fully enforce the one-major-bet constraint.

Makes a clear choiceMixed

It chooses matching, but does not clearly name what is sacrificed, and it still funds paid acquisition without a hard threshold.

Got right 3

Produces the required deliverableRight

It is a board-ready one-page strategy memo for the CEO, roughly within the requested length and usable with light edits.

Surfaces the central contradictionRight

It explicitly identifies that tutor supply grew 60% while 70% of tutors receive zero bookings and bookings grew only 8%.

Diagnosis before prescriptionRight

It diagnoses matching/search friction as the crux and proposes intake, routing, guarantee, and recurring booking actions aimed at that crux.

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

Choosing where to play and what not to do, from supplied evidence

The failure we’re looking for

Strategic-sounding aspirations without a diagnosis or a choice
