Every yoga studio has a version of it: two weeks, thirty days, three classes — a new-student special priced so the first step is easy. We run one in our own studio. And in most studios it is treated as a marketing product, judged by how many people buy it, when it is really aretention product judged by what happens on day thirty-one. A student on an intro is either a member on day thirty-one or a name on a list. Nothing else the studio does that month moves the numbers as much as which of those she becomes.
Why the unlimited window suits yoga
A yoga practice is a habit, and habits are built by frequency, not by enthusiasm. The single discounted class — the intro many studios inherited from the deal sites — fails for a structural reason: the second visit is where a habit starts, and a one-class offer never reaches it. The unlimited window is the opposite shape. Its economics push the student toward coming often, which is exactly the behavior that converts, and it gives the studio thirty days of visible evidence about who she is becoming. That evidence is the whole point, and most studios never look at it.
The dose-response: visits during the intro predict the join
Line up last quarter's intro students by how many times they visited and the pattern is unmistakable in every studio we have looked at: conversion climbs steeply with visits. The students who came once or twice mostly lapse. The ones who came six or more times mostly join — often before anyone asks them. The exact percentages are yours to measure, but the shape is the same everywhere, and it changes what the intro is for: not to sell a membership on day thirty, but to get the student to visit six on day twenty.
The four moments, and the note that belongs to each
1. The second visit, inside a week
The most predictive event in the whole intro is whether the second class happens within seven days of the first. A student who books again inside the week is forming the habit; one who drifts past ten days has usually decided, politely, not to say so. The note is the easiest one to write and the most valuable: same day as the first class, from the teacher if possible, naming the class she just took and the next one that fits — "loved having you this morning; Thursday's slow flow is the one to try next."
2. The mid-intro gap
A gap of more than ten days in the middle of a thirty-day window is a lapse in progress, and it is winnable in a way the day-thirty-one lapse is not, because the offer is still live and the sunk cost is on her side. The note is short and specific — a spot held in the class she liked, no guilt, twelve days left — and it is the note that most studios never send because nobody is watching the gap.
3. The membership conversation, at visit three
Not on day thirty. By visit three the student has an opinion about the studio and the studio has evidence about her, and the conversation is a natural one: here is how people like you tend to practice, here is what that costs as a member, here is what it costs as a pack. Price the intro close enough to the membership that day thirty-one is a step and not a cliff; the intro-conversion piece covers the pricing and the four definitional choices in detail.
4. The expiry date nobody is watching
On Mindbody the intro is a pricing option with an expiry date; on Mariana Tek, a time-limited product with the same. Either way, the platform knows exactly which day each intro ends, and in most studios nobody is looking at that date until a student asks at the desk whether her thing has run out. The last week of an intro is the studio's last cheap chance: a personal note at day twenty-four with the visit count attached — "you've been in eight times this month" — is the one that converts the undecided, because it tells her what she has already become.
Counting it honestly
Define the rate once and never switch. The version we recommend: students whose first class was in month M, who hold a paid membership within 30 days of the intro ending, divided by students who started an intro in month M. Two choices inside that matter. Count the cohort from the first class, not the purchase — an intro bought in January and first attended in March belongs to March, because that is when the studio actually met her. And keep lead conversion separate: the same twelve joiners can honestly be a 30% intro conversion and a 9% lead conversion in the same month, and the two numbers measure different things. If you run an auto-converting intro, measure the month-two retention of those students on its own line; a member who forgot to cancel is a different member from one who chose to join at visit six.
Where the numbers live
Whether the studio runs on Mindbody or Mariana Tek, the platform already records every intro purchase, the first class, every visit since, and the day the offer ends. All four moments are derivable from that. What has to be added is the reading — each intro on one line, this week, with the moment it has reached — and the follow-up, which is the part that loses to the front-desk rush in a studio where the owner also teaches the 6am.
That is the shape Xyzios gives a yoga studio. It connects on top of Mindbody or Mariana Tek — the platform stays your system of record — reads the studio's own history overnight, cohorts every intro from the first class, and puts the four moments on the Monday board with the note for each drafted in your voice. You read it, you tap, it goes. Nothing reaches a student without your approval, and nothing is written to Mindbody except what you tap or approve. Every student a note converts is traced in a ledger, so the intro's real conversion rate is an audit rather than a feeling.
Wherever you run the numbers, watch the visits, not the sales. The intro is decided on day ten, twenty, and twenty-four, and the studio that is present at those three moments will not need to be persuasive on day thirty. See how the follow-up gets drafted, or how the board reads a yoga studio.
