Memo: How Tutorly Actually Grows

To: Rachel Dunn and the exec team From: [Staff PM] Re: Growth loops, the paid plan, and squad focus for the next two quarters

The short version

Our growth comes mainly from organic search, and that engine runs on reviews. Reviews only come from completed lessons. Two things are slowing the engine. Most new tutors never get a first booking, and our click-through from search has dropped.

Tripling paid acquisition would buy our lowest-value parents at a marginal cost about 2.7 times what they are worth. It would also get us nowhere near 50,000. I recommend we hold paid flat or trim it, measure what it actually adds, and put all three squads on the review and search engine.

1. Our growth loops

``` LOOP A: Search–review (PRIMARY) Parent books → lesson completed → review → profile reaches 3+ reviews ↑ ↓ new parent ← clicks profile ← ranks/shows in search results

LOOP B: Parent referral Active parent → invites (0.31/mo) → 14% book → new active parent ↺

LOOP C: Tutor referral (supply) Tutor → refers tutor ($50) → new profile → [61% get no booking in 60 days → no reviews]

LINE D: Paid (not a loop) $ → new parent → (some lessons feed Loop A) → spend stops, flow stops ```

Loop A is primary. It is compounding, but it is being throttled. - It brings in 52% of new booking parents, the largest share. - These parents are among our best: 48% are still booking at six months, and their net LTV is $260. - Reviewed profiles capture the traffic. Profiles with three or more reviews get 81% of organic sessions, while profiles with none get 4%. - Organic sessions grew 40%, but booking parents grew only 20%. The loop is producing traffic faster than it converts. - There are two leaks: - Click-through has fallen. On our top 200 keywords it dropped from 6.1% to 5.0% since the March results-page changes, an 18% relative fall. - New tutors are stuck. 61% of new profiles have no booking within 60 days, so they can never earn the reviews that make them visible.

Loop B is contributing. - Referred parents are our best customers: 51% retained at six months, with a net LTV of $275. - It is not viral. Each active parent produces about 0.043 new booking parents a month. Over a typical parent lifetime that is a k-factor of roughly 0.3–0.4, well below 1. - There is a data problem. Applied to 37,000 parents, those invite rates imply about 1,600 referred parents a month. Our attribution says referrals are 9% of new parents, which is closer to 190 a month. One of these figures is wrong, and we need to know which before investing here.

Loop C is compounding the wrong thing. - Tutor referrals brought in 44% of new tutors. - Active tutors grew 62% while booking parents grew 20%. - As a result, bookings per tutor fell 25%, from 9.1 to 6.8 a month. - The loop mass-produces unreviewed profiles that search ignores, and probably creates frustrated tutors who leave. In supply terms it compounds; in value terms it is decaying.

Line D (paid) is decaying. - Paid parents are our weakest: 22% retained at six months, with a net LTV of $120. - Their cost is rising (see below). - Paid does feed Loop A a little, because these parents' lessons generate reviews. But it stops the moment spend stops.

2. The plan to triple paid acquisition

The 2.2 ratio is real but misleading. It divides our blended LTV of $210 by our average CAC of $95. Paid parents are worth $120, not $210, so the true paid ratio at average cost is about 1.3.

The marginal picture is much worse. Last quarter: - At $60k a month and $82 per parent, we bought about 732 parents a month. - At $90k a month and $109 per parent, we bought about 826 parents a month. - So the extra $30k bought about 94 extra parents, at roughly $320 each. - Against an LTV of $120, each marginal dollar returned about $0.38.

Tripling to $270k would push further up that cost curve. Even if the marginal cost stayed at $320, which it will not: - The extra $180k a month would buy about 560 parents a month, or about 3,400 over six months. - Those parents would be worth about $400k in lifetime value, for about $1.08M of spend. That is roughly $680k of value destroyed. - With 22% six-month retention, perhaps 1,500–2,000 of them would still be booking at the raise.

The 50,000 target is the real issue. Reaching it means adding 13,000 net parents in six months, a 35% gain. Last year we added 6,000 in twelve months, a 20% gain. No channel closes that gap by the raise: - Our current pace of about 500 net parents a month gets us to roughly 40,000. - Tripling paid might add 1,500–2,000. - The squad work below might add a similar amount. - My honest range is 41,000–43,000.

I would rather we take a credible story to Series B investors. That story is: a strengthening organic engine, rising retention, and channel-level unit economics we can defend. A burned-through paid spike will show up in their diligence.

My recommendations on paid: - Bring spend back to about $60k a month, where the cost per parent was $82. - Run a geo holdout to measure how many paid parents would have found us organically anyway. - Redirect the $30k saved, and the $180k not spent, into the work below. Some of it could fund first-lesson guarantees for new tutors.

3. Where the three squads should go

Every squad works within one guardrail. No incentive may be tied to leaving a review, directly or indirectly. Legal should review every test that touches the post-lesson flow. Review requests and referral or reward prompts should never appear together.

Squad 1: Search click-through recovery (Loop A, top of funnel)

Test: - Split-test the results-page and profile templates across matched keyword groups within the top 200. - Revert the March changes on half. - On the other half, test titles, meta descriptions, and review structured data.

Threshold: Click-through on the test groups recovers to 5.8% or better within eight weeks, with no loss of rankings. If it does, roll out to all keywords.

Stop condition: No lift of at least 0.3 points after eight weeks, or ranking losses on the test groups.

Why first: This is the cheapest win we have. Recovering the 18% fall is worth roughly a fifth more clicks on our best keywords, from traffic we already rank for.

Squad 2: New-tutor first booking (Loop A, the review bottleneck, plus fixing Loop C)

Test: - Give unreviewed but qualified tutors a "new tutor" slot in matching and in broad-search results. - Back their first lesson with a satisfaction guarantee: a refund or a free rebook if the parent is unhappy. - Gate the $50 tutor referral bonus to subjects and regions where bookings per tutor are above median, and pause it where we are oversupplied.

Threshold: - The share of new profiles booked within 60 days rises from 39% to 55%. - The share reaching three reviews within 90 days rises by 50% relative.

Guardrails: - Parent 30-day rebooking rate on lessons with new tutors stays within 2 points of baseline. - Total bookings do not fall.

Stop condition: No movement after two monthly tutor cohorts, or a breach of the parent rebooking guardrail.

Squad 3: Parent referral (Loop B)

Test: - Weeks 1–2: reconcile the invite and attribution data. This tells us whether the loop is under-attributed (good news) or the invite counts are inflated. - Then test referral prompts at natural moments, such as a lesson milestone or a rebooking. These prompts must be separate from any review request. - Test a two-sided offer: $20 for the referrer and $20 off the referred parent's first lesson.

Threshold: - Invites per active parent rise from 0.31 to 0.45 a month. - Invite conversion holds at 14% or better. - Cost per referred booking parent stays under $60, against an LTV of $275.

Stop condition: - Cost per referred booking parent goes above $90. - Fraud or self-referral exceeds 5% of rewards. - No lift in invite rate after six weeks.

What I am asking the exec team to decide

1. Keep paid at about $60k a month and run an incrementality holdout, rather than tripling it.
2. Replace the 50,000 headline with a Series B narrative built on growth in organic and referral share, six-month retention, and bookings per tutor. Our honest forecast is 41,000–43,000 parents.
3. Assign the three squads as above, with a checkpoint at the offsite plus eight weeks.

I am happy to walk through the arithmetic in detail before the offsite.

To: Rachel Dunn and Executive Team From: Staff PM, Tutorly Subject: Grow booking demand, not acquisition spend Planning horizon: Next two quarters

Recommendation

Do not commit to $270,000/month in paid acquisition. Our primary growth engine is organic discovery of proven tutors, reinforced by completed lessons and reviews. That engine is growing, but its distribution is concentrated and its conversion into bookings is weakening. Meanwhile, tutor supply is growing much faster than demand, and paid acquisition has deteriorating marginal economics.

Put our three squads on organic discovery, demand-led tutor activation, and parent referrals. Keep paid acquisition as a tightly gated contributor—not the engine assumed to deliver 50,000 booking parents.

1. How we actually grow

```text PRIMARY: Organic discovery / reputation Search → tutor profile → booking → completed paid lesson → genuine review → stronger discovery/conversion → more bookings

Parent referrals Booking parent → invitation → new booking parent → invitations

Tutor referrals Active tutor → referred tutor → onboarding → additional supply → bookings only if matching parent demand exists

Paid acquisition / reinvestment Spend → new booking parent → repeat lessons → commission → acquisition budget → more spend ```

Organic/reputation: our primary compounding mechanism, but uneven and constrained. Organic supplies 52% of new booking parents, versus paid’s 39% and referrals’ 9%. These parents have 48% six-month retention and $260 net LTV. Completed lessons generate reviews, which can improve subsequent discovery and conversion without buying every next customer.

Profiles with at least three reviews capture 81% of organic profile sessions; unreviewed profiles capture only 4%. This supports the mechanism, but does not establish that reviews alone cause the traffic difference.

The warning signs are substantial:

• Organic profile sessions rose 40%, but booking parents rose only 20%.
• Search CTR fell from 6.1% to 5.0%, an 18% relative decline.
• 61% of recently created profiles had no booking within 60 days—and therefore no reviews.

This is a reinforcing loop concentrated in established profiles, not proof that adding more profiles compounds demand.

Parent referrals: contributing, not yet demonstrably self-sustaining. Each active parent generates:

`0.31 invites/month × 14% conversion = 0.0434 new booking parents/month`

That is 4.34 new booking parents per 100 active parents per month. Even six fully active months produce only 0.26 referred booking parents per parent. We lack lifetime active-month data to calculate a full reproduction rate.

Referral customers are valuable: 51% six-month retention and $275 net LTV, with a $20 credit per successful referral. But the credit alone is not the fully loaded, incremental CAC.

Tutor referrals: contributing supply, with decaying demand yield. They produced 44% of new tutors, incentivized by $50 per onboarded tutor. Tutor count grew 62%, while bookings per active tutor fell 25%, from 9.1 to 6.8.

Multiplying those figures suggests monthly bookings increased roughly 21%—from 129,000 to 156,000—while supply expanded three times as quickly. Onboarding more tutors is not equivalent to growing the marketplace. We cannot establish that tutor referrals are self-compounding; their booking yield is deteriorating.

Paid: contributing customers, with decaying marginal economics. Paid delivers 39% of new booking parents, but only 22% remain booking after six months, and their net LTV is $120. Each $40 lesson yields $7.20 commission, before other costs. Reinvestment is possible only if acquisition leaves enough economic surplus; spend itself is not a compounding advantage.

2. Why tripling paid is not the current answer

The quoted 2.2 LTV:CAC divides blended LTV, $210, by paid CAC, $95. It combines different customer populations.

Paid’s actual ratios are:

• Annual average: $120 / $95 = 1.26
• Latest quarter: $120 / $109 = 1.10

That leaves only $25, then $11, of lifetime surplus per acquired parent on the supplied net-LTV basis.

The marginal picture is worse:

• $60,000/month at $82 CAC bought approximately 732 parents.
• $90,000/month at $109 CAC bought approximately 826 parents.
• The extra $30,000 bought only 94 additional parents: approximately $319 per additional parent.

This before/after comparison is not a controlled incrementality estimate, but it is a strong warning against extrapolating average CAC.

Even if CAC stayed at $109, $270,000/month would acquire approximately 2,477 parents/month. Relative to current spend, that adds roughly 9,900 gross parents over six months, before churn—not the 13,000 net increase required to reach 50,000. Organic and referrals could close part of that gap, but the pack lacks monthly cohort flows needed to forecast it honestly.

Decision: Freeze paid at no more than $90,000/month during a four-week incrementality audit; reduce spend where marginal economics fail. Release additional budget in steps of at most 25%, not a single tripling. Require incremental CAC of $80 or less—a proposed 1.5× paid LTV:CAC hurdle—and no deterioration in cohort quality. Stop any expansion that fails that hurdle. These are management thresholds, not observed performance.

3. Three squads for two quarters

Squad 1 — Recover organic booking demand

Test: Diagnose the CTR decline, then test search-facing changes we control—titles, snippets, profile information and relevant landing experiences—using matched keyword/profile holdouts. Prioritize proven tutors with available capacity. Do not assume we can reverse external search-results changes.

Threshold: Within 8–10 weeks, achieve at least 10% lift in organic first-booking conversion per eligible search impression, with CTR trending toward 5.8% or better, and no deterioration in cancellations or early repeat booking versus control.

Stop condition: Stop variants that improve clicks without incremental bookings. If two adequately powered iterations fail, redirect from presentation fixes to intent and landing-page mismatch.

Quarter two: Scale winning changes; continue measuring completed lessons and cohort retention, not sessions alone.

Squad 2 — Activate supply where demand exists

Test: Pause broad tutor-referral expansion. In underserved subject/time/location segments, test availability guidance and matching that help new tutors earn their first paid, completed lesson. Randomize at market-cluster level to detect displacement from existing tutors.

Threshold: Reduce the 60-day no-booking rate from 61% to 50% or lower, while increasing total completed bookings in treated markets by at least 5%. Require non-negative incremental contribution after intervention costs.

Stop condition: Stop if new-tutor activation merely redistributes existing bookings or worsens cancellations and lesson quality.

Quarter two: Expand only in demonstrated demand gaps. Request honest reviews after completed lessons; never reward reviews or require positive feedback.

Squad 3 — Grow retained demand through parent referrals

Test: Keep the $20 referral credit unchanged. Test referral prompts after successful lessons and repeat bookings against randomized holdouts. Own the paid incrementality audit as the common acquisition-measurement workstream.

Threshold: Raise invitations from 0.31 to at least 0.45 per active parent/month, maintain 14% conversion, and demonstrate at least 25% lift in incremental referred booking parents, with fully loaded incremental CAC below $80 and early repeat booking no worse than control.

Stop condition: Stop prompts that cause annoyance, reduce repeat booking, or merely relabel parents who would have arrived organically. Do not scale on invitations alone.

Quarter two: Scale proven referral treatments; validate six-month retention as cohorts mature.

The offsite should approve these experiments and gates—not an unsupported acquisition forecast. Our objective is 50,000 booking parents, not 50,000 acquired accounts or an ever-larger tutor directory.
