The Cohort Model — Why Ezzi Clarity Sells Seats, Not Hours

This document exists to hold the full economic reasoning behind the consulting arm’s core strategic decision — stated briefly in company/strategy/roadmap.md §3 and company/strategy/business-plan.md §1 — in one place, since it’s referenced from several other documents and deserves to be argued in full rather than repeated in fragments each time.

The problem with one-on-one coaching at an accessible price

One-on-one coaching, priced accessibly, has a hard income ceiling that no amount of hustle fixes. At 6–10 hours a week — the fixed capacity constraint this entire business is built around — even a fully booked 1:1 practice produces modest income and, more importantly, zero leverage. Every new client costs the founder exactly the same effort as the last one did. There’s no experience curve that lowers the marginal cost of the tenth client relative to the first, because the prep for each session is essentially thrown away once that session ends — a lesson planned and delivered for one family doesn’t reduce the work needed to plan and deliver the same lesson for the next family. The founder’s own comparison point, drawn from the competitive landscape in company/strategy/business-plan.md §4.3, is that a generic academic-coaching baseline in this market runs around $25/hour, and even an accessible 1:1 rate with no reuse tops out around $60–75/hour. Neither number, multiplied by a 6–10 hour week, adds up to more than a modest side income — and it stays modest indefinitely, because the structure has no way to compound.

How the cohort format inverts the economics

A small-group program inverts this completely. The same preparation — the same session content, the same workbook, the same talking points refined after the first delivery — serves eight families instead of one. That single change does two things simultaneously, and both matter. It keeps the price per family low, which is not a marketing nicety but a direct expression of the practice’s accessibility commitment (company/brand/positioning.md): a family shouldn’t have to pay a premium 1:1 rate to get real help. And at the same time it roughly doubles the founder’s effective hourly rate, because the fixed cost of preparing a session is now spread across eight paying families instead of amortized over exactly one.

The concrete numbers, as currently modeled in company/strategy/business-plan.md §10.2: a full cohort of eight families at $150 each generates $1,200 in revenue. The first run of a new cohort costs roughly 14 hours total — about 6 hours of prep (built once), 6 hours of delivery across the four sessions, and 2 hours of admin. Every subsequent run of that same cohort format drops to roughly 8 hours, because the prep is already built and just needs reuse and light refresh. That yields an effective hourly rate of about $86/hour on the first cohort and about $150/hour on every repeat run after that — a rate that keeps climbing in practice terms (not literally, but in effective leverage) the more times the same prepared material gets reused, while the price the family actually pays never goes up. Compare that to the $60–75/hour ceiling of accessible 1:1 work with no reuse, and the case is not subtle: the cohort model outperforms 1:1 coaching on effective hourly rate while simultaneously keeping the per-family price lower than typical private tutoring for a comparable block of time. That combination — better economics for the founder and a better price for the family — is only possible because of the reuse built into the group format; it would not be achievable by simply charging more per 1:1 hour, which would abandon the accessibility commitment instead of honouring it.

There’s a second-order effect worth naming too: a room of eight families produces referrals in a way that eight separate 1:1 phone calls never do, simply because parents in the same room talk to each other before and after sessions in a way that isolated 1:1 clients structurally cannot. The cohort format doesn’t just make each hour of founder time more valuable — it makes each family’s presence in the room slightly more valuable to acquiring the next family, which no 1:1 engagement can replicate no matter how satisfied that one client is.

Why 1:1 work doesn’t disappear — it changes role

None of this means 1:1 coaching is abandoned. It becomes the paid add-on, offered at $85/hour specifically to cohort alumni rather than marketed cold to new prospects (per company/strategy/business-plan.md §5.2), and it remains the right format for the highest-value, most individualized conversations a family might need after completing the group program. What changes is its role in the business: it is no longer the foundation the practice’s income depends on, because a foundation built entirely on 1:1 hours cannot escape the ceiling described above no matter how skilled or efficient the founder becomes at delivering it. The cohort is the foundation now; 1:1 work is the premium layer built on top of it, sold only once a family already has direct experience of the program’s value from having sat through the group sessions together.
