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 — make every good match count

Recommendation: Put our £1.2m behind improving the first tutor match, not broad paid acquisition. Tutor supply is growing far faster than bookings, 70% of tutors get no booking in a typical month, and students say finding the right tutor is their main problem. Buying more student traffic before fixing that experience risks paying to send more families into the same frustration. The encouraging signal is that students who book again show a 64% repeat rate: when a match works, there is reason to believe students stay.

The bet: a guided matching and first-booking service

Build a faster, more trusted path from a student’s need to a first lesson. Ask about subject, exam level, goals, budget, availability and preferred teaching style; then show a short, ranked list of tutors who are available and suitable—not a directory students must search alone. Make tutor profiles clearer on relevant experience and approach, and prompt tutors to respond quickly. For students who still struggle, offer human-assisted matching.

Start with the subjects and exam levels that already have the strongest demand and enough suitable tutors. Use actual enquiries, bookings, repeat behaviour and student feedback to improve recommendations. This is one integrated liquidity bet: make existing demand easier to serve with existing supply, rather than adding supply or buying broad traffic.

How we will execute

In the first 90 days, analyse the booking funnel and pilot assisted matching in a few high-demand subject/exam segments. Compare it with the current journey on first booking, time to match, cancellations and student satisfaction. In months 4–6, automate the most successful parts and improve availability and profile information. In months 7–12, expand only where the pilot improves bookings without harming quality. Help tutors without bookings improve their profiles or availability; stop actively promoting tutors who are unavailable or consistently unresponsive.

Allocate the £1.2m across the year: £450k product and data, £300k matching and student support, £250k tutor onboarding and quality, £100k testing and measurement, and £100k contingency. Release funding in stages, with a formal review after the pilot.1

What success looks like

By month 12, target 6,000 monthly bookings (up from 4,000) and at least 45% of active tutors receiving a booking in a typical month (up from 30%). Also improve first-booking conversion and time to first lesson, while maintaining or improving repeat booking, cancellation and satisfaction rates. Report results by subject and exam level so growth cannot hide weak or overloaded segments.

Hold broad paid acquisition for now. Run only small, measurable acquisition tests in segments where matching is working; scale spend only if the resulting students book and repeat at acceptable acquisition cost. If the pilot fails to improve first bookings, stop and reassess before committing the remaining funds. This gives the board a measurable growth bet while protecting our 18-month runway.

What a PM had to fix

  1. 1Invented evidenceVerify or remove the claimTargeted repair

    What we’d changeTreat £1.2m as a funding ceiling, not a spending commitment. Assuming one-hour lessons, reaching 6,000 monthly bookings adds only £12k–18k in monthly commission revenue before costs. That target alone does not justify the investment. Cost the 90-day matching pilot first; release further funding only if incremental completed bookings, repeat behaviour and service costs support a credible path to covering the investment within our financing horizon. Assess that path against actual cash burn and remaining runway before scaling.

Output

Tutorly: 12-Month Growth Strategy (Board Briefing)

Executive Summary

Tutorly has reached a critical inflection point, plateauing at roughly 4,000 bookings per month. While tutor supply has surged by 60% year-on-year, demand has lagged behind, with bookings up only 8%. Consequently, 70% of our active tutors receive zero bookings in a typical month, threatening supply quality and platform retention.

With 18 months of runway and £1.2m in capital, we face a strategic choice. While the board traditionally advocates for paid student acquisition, qualitative research reveals that our primary bottleneck is not awareness, but friction in matching. Students cite “finding the right tutor” as their top hurdle, while tutors report “not enough students.” Throwing capital at top-of-funnel paid acquisition will merely leak budget into an inefficient discovery funnel.

Instead, our single major bet for the next 12 months is to re-engineer the marketplace discovery and matching engine, transforming Tutorly from a static directory into an intelligent, high-conversion matching platform.

The Core Problem & Diagnosis

Our core metrics tell a clear story of imbalance: * The Supply Glut: 6,500 active tutors vs. 11,000 active students, resulting in 70% of tutors experiencing zero-booking months. * The Demand Efficiency: Repeat booking is healthy at 64% for students who book twice, proving that product-market fit exists once a match is made4. The failure is entirely in initial activation and discovery.1

The 12-Month Strategic Bet: Intelligent Matchmaking & Activation

We will deploy our £1.2m budget across three synchronized pillars over the next 12 months to drive bookings from 4,000 to 10,000+ monthly transactions.

1. Algorithmic Matching & Guided Discovery (Months 1–4)

  • Action: Shift from manual search filters to an AI-driven, intent-based matching questionnaire for incoming students. Students specify learning style, goals, budget (£30–45/hr), and schedule, and receive top-3 instant tutor recommendations.
  • Investment: £400k in product engineering, UX redesign, and recommendation algorithms.

2. Supply-Side Activation & Tiered Visibility (Months 5–8)

  • Action: Address the 70% zero-booking tutor rate by introducing performance-backed visibility tiers, response-time incentives, and automated profile optimization tools. Tutors who maintain high responsiveness and trial conversion rates are prioritized in the new matching engine.
  • Investment: £300k in tutor success tooling, automated coaching, and CRM workflows.2

3. Targeted Demand Amplification (Months 9–12)

  • Action: With conversion rates optimized, deploy the remaining £500k into targeted performance marketing and SEO. Rather than broad, leaky acquisition campaigns, we will target high-intent secondary-school parents with hyper-specific landing pages tied directly to instant matching funnels.
  • Investment: £500k in performance channels, referral loops, and parent trust initiatives.

Financial Impact & Board Recommendation

By fixing the matching bottleneck first, we project a rise in trial-to-booking conversion rates from current lows to over 25%, lifting monthly bookings past 10,0003 and securing a sustainable, high-margin marketplace model well within our 18-month runway.

We request board approval to allocate the £1.2m capital to this intelligent matching strategy, prioritizing structural efficiency over superficial top-of-funnel spend.

What a PM had to fix

  1. 1Hypothesis stated as factReframe it as a hypothesisStart again

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

    What we’d changePresent matching friction as the hypothesis the research suggests, not a proven diagnosis, and stage the spending so the board learns before it commits the full £1.2m.

  2. 2Constraint missedRestore the constraintSubstantial rework

    Source: BriefWe can fund one major bet.

    What we’d changeCut back to one bet. Tutor tooling needs its own case when supply already far outstrips bookings.

  3. 3Invented evidenceVerify or remove the claimTargeted repair

    What we’d changeRemove the forecast or show the model: no conversion baseline is given, and nothing connects 25% to 10,000 bookings.

  4. 4Hypothesis stated as factReframe it as a hypothesisQuick edit

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

    What we’d changeA 64% repeat rate among two-time bookers suggests value after a match. It doesn't prove product-market fit.
