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.

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 does

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

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.

Output

Tutorly 12-Month Strategy: Fix Matching, Then Scale

Recommendation

Put the £1.2m behind one bet: guided matching with a first-lesson guarantee. Paid acquisition comes second, released in stages once the funnel converts.

Why not paid acquisition first

Tutor supply is up 60% and bookings only 8%, so the constraint is not volume. Seventy percent of tutors get no bookings, and students say their biggest problem is finding the right tutor. Tutors say "not enough students," but that is a symptom of poor discovery, not a shortage of demand alone.

The economics are also tight. At an average £37.50 lesson and 20% commission, we earn about £7.50 per booking. A £50 acquisition cost needs roughly seven bookings from a student just to break even. Our best evidence of retention is that 64% of students who book twice book again, but we don't yet know how many get to a second booking. Paying to send more students into a search experience they find frustrating risks buying churn.

The bet

1. Guided matching (about £600k). Replace browse-and-search with a short intake (subject, exam board, grade target, learning needs, availability, budget) that returns three ranked tutors. Add structured tutor profiles and quality signals such as response time, outcomes and reviews. Route new demand to under-booked tutors who fit well, rather than only to the top few.

2. First-lesson guarantee (about £300k). If the first lesson isn't right, the student is rematched and the lesson is free, funded by us. This targets the drop-off before the second booking, which is where the strong repeat behaviour begins.

3. Supply curation (about £100k). Stop passive tutor onboarding. Admit tutors by subject-level demand, and give inactive tutors coaching or profile support, or deprioritise them.

4. Gated acquisition reserve (£200k). Held back and released only when the gates below are met.

Gates for releasing acquisition spend

Two consecutive months of: - first-to-second booking conversion up at least 10 points from baseline; - median time to first booking under 48 hours; - modelled payback on acquisition inside 6 months.

Until then, test small paid channels only to measure cost per matched student.

Targets (month 12)

  • Bookings: 4,000 → 6,000+ per month
  • Tutors with at least one booking a month: 30% → 50%
  • Students reaching a second booking: +10 points
  • Student satisfaction after first lesson: tracked from launch

Timeline

  • Months 1–2: Instrument the funnel (search → enquiry → first lesson → second lesson). Establish the baseline. Interview 30 students and 30 tutors.
  • Months 3–6: Launch matching to one or two high-demand subjects, such as GCSE maths and sciences. Run against a control group.
  • Months 7–9: Roll out across all subjects, and launch the guarantee if the pilot shows it pays back.
  • Months 10–12: Release acquisition spend if the gates are met. Report to the board.

Risks

  • Matching doesn't lift conversion. Pilots with control groups will show this by month 6, leaving 12 months of runway to change course.
  • Guarantee costs exceed benefit. We cap exposure per student and monitor abuse.
  • Tutor churn from curation. We prioritise communication and coaching before any deprioritisation.

Ask of the board

Approve the matching bet and the staged acquisition gate. If the board is not willing to defer scaled paid acquisition, the fallback is a capped £150k test with cost per second booking as the success measure.

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
