You fill cohorts in advance by spending to the enrolment window, not evenly all year. Ramp budget when the window opens, push hardest at peak, ease off as seats fill, and pull back once the cohort is full. Elec Training filled cohorts while cost per lead fell from £257 to £5.28.
We scope the No-BS Guarantee after the audit. Baseline, target, and deadline, all in writing. We don't guarantee your sales team's close rate. We guarantee the acquisition improvement we agree to control.
We set the day-one baseline from your own accounts.
One measurable acquisition improvement and one deadline go in writing.
If the written baseline improvement is missed, we keep working without management fees.
Because a cohort business does not sell evenly, so it should not spend evenly. Demand concentrates in the enrolment window before each intake. A flat budget starves the weeks when seats are actually decided, wastes spend in the months when nobody can enrol, and leaves the provider panicking the month before the start date. StudentFlow spends to the intake date instead.
Four phases, mapped to each intake before the window opens, so budget lands when a decision is actually possible and stops when it is not.
Budget climbs the day enrolment opens. The waitlist gets first call, paid reach rebuilds the audience, and early enrolments anchor the cohort and the platforms’ signal.
The weeks when most students decide. Spend runs at its ceiling, creative rotates fastest, and admissions gets same-day handovers of course-fit inquiries with funding and eligibility checks already done.
As confirmed enrolments climb toward capacity, budget steps down. There is no reason to pay peak prices for seats that are already spoken for.
Spend drops to a maintenance floor. New demand is not thrown away; it flows onto the waitlist for the next intake, where it becomes the cheapest seats you will ever fill.
The same curve, re-run for every intake on your calendar, judged against cost per enrolled student. What the whole system costs is on the cost page.
Find your cost per enrolled studentBetween intakes you cannot sell a seat, but you can bank the intent. A waitlist is demand storage. Low-cost capture runs year round: course guides, funding checklists, and eligibility checks that qualify people while they wait. When the window opens, the waitlist enrols first, at a cost per enrolled student no cold audience can match, and it hands the platforms a warm signal to scale the paid push from.
Skip the waitlist and every window starts from zero, paying peak prices to rebuild an audience you already paid for once. This is also where an in-house content marketer and StudentFlow work best together; the split is on the agency vs in-house page.
Three ways cohorts end up half empty on day one. All three are budget decisions, not marketing luck.
The flat budget quietly drains spend into months when nobody can enrol, then has nothing extra to give when the window opens. The panic push in the final month pays peak auction prices for a decision window that is already closing.
Window-shoppers spike during peak weeks too. Without course-fit grading and funding and eligibility checks, admissions drowns exactly when it matters most. The goal metric is cost per enrolled student; the full cost math is on the cost page.
No waitlist means every inquiry that arrives after a cohort fills is wasted, and every new window starts cold. Store the demand, nurture it, and release it when the window opens. That is the cheapest cohort you will ever fill.
Budget paced to intakes, inquiries graded for course-fit, and admissions fed enrolment-ready students. Cohorts sold out ahead of start dates. Client-reported.
They were proactive in keeping us informed, explaining performance in a straightforward way.
Because the curve moves weekly with confirmed enrolments. Budget, creative, tracking, and the admissions handover have to sit in one loop, the same loop that runs the Rocketship Method. Split it across vendors and the window closes while the emails are still flying. One team, one number: cost per enrolled student.
Spend to the window. My name’s on it.
