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.

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.

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.

Tutorly: 12-Month Strategy for the Board

Decision requested: Back one major bet: a guided matching service that helps students find the right tutor and converts successful introductions into repeat lessons. Commit up to £1.2m, released against evidence. Do not make broad paid acquisition the primary strategy yet.

Why this bet

Tutorly’s constraint appears to be successful matching, not tutor availability. Tutor supply grew 60% year on year, while bookings grew just 8%; 70% of tutors receive no bookings in a typical month. Adding more supply will not solve this imbalance.

Students identify “finding the right tutor” as their main problem. The 64% repeat booking rate among students who book twice suggests value after a relationship forms—but excludes students who never reach a second lesson. It does not establish strong retention across the whole marketplace.

The board’s acquisition thesis may be right: insufficient student demand could explain underutilisation. But buying more traffic before testing the matching bottleneck risks paying to reproduce today’s disappointing conversion. At £6–9 commission per lesson, acquisition economics require sustained repeat bookings.

The major bet: guided matching

Replace open-ended tutor browsing as the default journey with a short intake covering subject, exam board, goals, budget, availability and learning preferences. Present three suitable, genuinely available tutors, explain each recommendation and make the first booking straightforward.

Start with human-assisted matching rather than a large algorithm build. Use this service to learn what predicts a successful relationship, then automate proven steps. After the first lesson, collect fit feedback, offer a quick rematch where necessary and prompt a recurring booking where appropriate.

Concentrate initially on the highest-volume subject and exam-board segments identified in our data. Pause broad tutor recruitment; prioritise responsive existing tutors with relevant availability. Success means productive student–tutor relationships, not equal booking distribution across all 6,500 tutors.

Execution and investment

Months 1–3: Diagnose and test. Establish funnel baselines from student arrival through first, second and subsequent lessons. Run a controlled experiment comparing guided matching with today’s journey, using comparable student cohorts. Measure tutor responsiveness and matching-service cost.

Months 4–6: Prove repeatability. Expand only if the pilot improves completed bookings and repeat behaviour—not merely enquiry volume. Refine recommendations, automate intake and scheduling, and establish contribution economics after matching support costs.

Months 7–12: Scale the winner. Roll out proven workflows across suitable segments. Increase paid student acquisition only where matched cohorts demonstrate viable acquisition payback, turning acquisition into distribution for the same bet.

Allocate £450k to product and engineering, £350k to matching operations, £150k to research and measurement, and £250k as a gated scaling reserve. Review spending quarterly against the remaining runway.

Board scorecard and stop rules

Set initial targets of 25% higher first-booking conversion and 20% higher second-booking conversion versus control, with no deterioration in cancellations or lesson satisfaction. Track 90-day bookings and contribution per student, including acquisition and service costs.

Aim to reach 6,000 monthly bookings by month 12, as a planning target rather than a forecast. If the six-month evidence shows no meaningful improvement or an uneconomic service cost, stop expansion and preserve capital.

Strategic principle: Prove that Tutorly can reliably turn student demand into lasting tutoring relationships before paying substantially more to generate that demand.

Where they differ 5

Addresses the actual decisionMixedRight
Gemini 3.8 Flash · API

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

GPT-6.1 Sol · API

Commits to one bet (guided matching) early, says what is sacrificed (broad paid acquisition as primary strategy), and states the condition (no meaningful improvement or uneconomic cost) that would change the call.

Respects explicit constraintsMixedRight
Gemini 3.8 Flash · API

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.

GPT-6.1 Sol · API

The output is a one-page strategy of about 500 words for the CEO to take to the board, commits to one major bet within the £1.2m funding, and respects all stated constraints.

Identifies material uncertaintyWrongRight
Gemini 3.8 Flash · API

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

GPT-6.1 Sol · API

Names the uncertainty (whether matching or demand is the real bottleneck), acknowledges the board's thesis may be right, and specifies that six-month evidence of no improvement or uneconomic cost would stop expansion.

Makes a clear choiceMixedRight
Gemini 3.8 Flash · API

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

GPT-6.1 Sol · API

Chooses guided matching as the one bet and explicitly forgoes broad paid acquisition as the primary strategy.

Proposes tests that could failWrongRight
Gemini 3.8 Flash · API

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

GPT-6.1 Sol · API

Proposes numeric thresholds (25% higher first-booking conversion, 20% higher second-booking conversion), a six-month window, and a clear stop rule (no meaningful improvement or uneconomic cost).

All got wrong 2

Uses the supplied evidence correctlyWrongWrong
Gemini 3.8 Flash · API

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.

GPT-6.1 Sol · API

The output makes unsupported claims about the current system (open-ended tutor browsing as default journey, existence of data on subject/exam-board segments) that are not in the supplied context.

Avoids unsupported claimsWrongWrong
Gemini 3.8 Flash · API

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

GPT-6.1 Sol · API

Presents as fact that the current default journey is open-ended tutor browsing and that data on highest-volume subject/exam-board segments exists, neither of which is in the supplied evidence.

All got right 3

Produces the required deliverableRightRight
Gemini 3.8 Flash · API

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

GPT-6.1 Sol · API

Delivers a complete, actionable one-page strategy (~516 words) for the CEO to take to the board, with decision, rationale, execution plan, and scorecard.

Surfaces the central contradictionRightRight
Gemini 3.8 Flash · API

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

GPT-6.1 Sol · API

Clearly identifies that supply grew 60% while bookings grew only 8% and 70% of tutors get zero bookings, surfacing the mismatch.

Diagnosis before prescriptionRightRight
Gemini 3.8 Flash · API

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

GPT-6.1 Sol · API

States the crux (matching, not supply, is the constraint) and each major action (guided matching, human-assisted intake, rematch) directly addresses it.

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
