Introduction: Why Boutique Fitness Breaks Generic Software

It was a Saturday morning at my third studio, and the schedule was eating itself.

A routine update to recurring class blocks had cascaded into something stranger: two instructors double-booked across three time slots, a 9:15 AM class showing as cancelled to members but active in the staff app, and a small but loud queue of refund demands stacking up in the inbox before I had finished my first coffee. The software had done exactly what we asked it to do. The problem was that what we had asked it to do — manage recurring blocks, instructor swaps, member-facing visibility, and the billing that hangs off each booking — sat at the intersection of four different modules, and those modules did not actually trust each other.

I spent the rest of that weekend doing what every boutique studio operator eventually does: working around the tool. Manually messaging members. Manually crediting class packs. Manually rebuilding the schedule in a spreadsheet because the spreadsheet, at least, did not have opinions. By Monday, three members had cancelled their memberships. One of them, a regular for two years, told the front desk that the studio "felt disorganised lately." It did not. The software did. But to the member, those are the same thing.

That weekend is the seed of this book. By the time I sold out of the operating side of the business, I had run five studios through three different software stacks, watched two of them shift from purpose-built fitness tools into bloated horizontal platforms, and reached a conclusion that has only sharpened since I crossed over to the technical co-founder side of the table: boutique fitness is not a generic subscription business, and generic subscription software cannot run it well.

The boutique studio is not a SaaS company in spandex

There is a tempting analogy that gets drawn at investor dinners: a boutique fitness studio is "basically a subscription business." Members pay monthly. Some churn. Retain them and the LTV compounds. Tools like Stripe, Calendly, and a CRM should, in theory, cover it.

This analogy is wrong in ways that matter operationally.

A generic subscription business has one product (access), one billing event (the monthly charge), and a relatively low-touch customer relationship. A boutique fitness studio has, in any given week:

- Multiple billing instruments running in parallel: unlimited memberships, capped memberships, class packs of varying sizes and expiry windows, drop-ins, intro offers, family add-ons, and corporate accounts — each with its own proration and refund logic. - Inventory that is simultaneously time, space, and human: a 6:30 AM class is not just a calendar event; it is a finite-capacity room, a specific instructor whose absence means cancellation, and a waitlist that has to clear in a defined order. - A relationship economy: members do not just pay for access, they pay for the instructor they bonded with on a Tuesday night when their week was falling apart. Lose that instructor and you can lose ten members in a fortnight. - A "forever transaction" dynamic in which the value of the membership has to be re-demonstrated continuously, not just at signup, because the customer can quietly stop showing up long before they cancel (Baxter, 2015).

Generic horizontal SaaS — payments tools, scheduling tools, CRMs — was not built around this operational DNA. It was built around the most generic possible version of "business." The fit is approximately right, which is the worst kind of fit, because it lets you launch and grow before the seams start splitting.

Vertical SaaS, briefly defined

The term vertical SaaS describes software built for the specific workflows of a single industry, as opposed to horizontal SaaS, which sells the same general-purpose tool (a CRM, a scheduler, a payments processor) into every industry. Vertical SaaS companies tend to capture more revenue per customer than horizontal equivalents, because they embed into industry-specific workflows that are too operationally complex for generic tools to serve well; fitness scheduling and billing are cited as canonical examples of this dynamic (Andreessen Horowitz, 2022).

Boutique fitness is, in my view, a structurally ideal candidate for vertical SaaS, and an underserved one, for four reasons:

1. The workflow is specific enough that generic tools genuinely fail at it. This is not a preference; it is the scheduling-cascade story above, repeated in thousands of studios every week. 2. The buyer and the user are often the same person — the studio owner — which collapses the enterprise sales cycle into something closer to consumer software economics. 3. The market is large enough to support category-defining companies but small enough that horizontal incumbents do not optimise for it. Boutique fitness has shown resilience as a segment of the broader industry, including post-pandemic, even as large-format clubs faced steeper recovery curves (IHRSA, 2023). 4. Consumer willingness to pay for premium fitness has held up. U.S. household spending on recreation and fitness services has grown over the past decade, with premium formats capturing a meaningful share of that growth (U.S. Bureau of Labor Statistics, 2023).

The dominant incumbent in this market, Mindbody, illustrates both the opportunity and the cautionary tale. Founded in 2001 as a focused tool for studios, it expanded over two decades into payments, marketing, and a consumer marketplace, and was acquired by Vista Equity in 2019 (Stollmeyer, 2019). That expansion made it the default platform for a generation of studio owners. It also created the dissatisfaction gap — the feature bloat, the rising prices, the workflow friction — that newer vertical entrants, including the company I now help build, are working to close. This is a textbook instance of what Christensen-derived analysis calls the incumbent's curse: a platform serving its largest customers so thoroughly that it stops serving its smallest ones well (Christensen, 1997).

I want to be honest about that framing from the outset. Mindbody is not a villain in this book. It is the necessary incumbent that built much of the muscle memory the industry now operates on, and it is a cautionary arc that any vertical SaaS company — mine included — has to actively work not to repeat.

The three pillars

This book is organised around the three jobs studios actually hire software to do. The framing borrows from jobs-to-be-done thinking, which holds that customers hire products to make progress on a specific job, and that products lose clarity when they try to do too many at once (Traynor et al., 2016; Christensen, 2016).

Those three jobs, as I came to understand them across five studios:

- Billing integrity. Collecting recurring revenue reliably across memberships, class packs, and one-off purchases — without silent failures, without proration errors, and without the operator becoming the reconciliation engine of last resort. - Scheduling intelligence. Filling classes without friction: capacity, waitlists, instructor substitutions, and member-facing visibility that all agree on the same source of truth. - Retention mechanics. Detecting and acting on the early signals that a member is quietly disengaging, well before they cancel. Behavioural recency and frequency features — essentially, attendance cadence — outperform demographic data as predictors of subscription churn, which makes attendance the single most actionable retention signal a fitness platform can surface (Verbeke et al., 2012).

Each of these jobs gets its own deep treatment later in the book. The argument I will make repeatedly is that doing any one of them well requires the other two to be in the same system, sharing the same data — which is precisely what a stitched-together stack of horizontal tools cannot deliver, and which ecosystem strategy describes as the orchestration advantage of bringing the minimum viable set of complements under one workflow (Adner, 2021).

Why I'm writing this, and the conflict I have to name

I have a dual vantage point that I want to be upfront about. I spent years as a boutique fitness operator running a five-studio chain. I now work as a technical co-founder building software in this category. That gives me what venture investors sometimes call operator-founder advantage — asymmetric insight into the workflow pain, buyer psychology, and the gap between what studio owners say they want and what they actually need. It is real, and it is also time-limited; the further I get from the operator chair, the more I have to actively maintain the connection through structured customer discovery rather than relying on memory (Torres, 2021).

It also means I have a commercial interest in some of the conclusions this book reaches. A reader would be right to push back on that. My commitment is straightforward: I will cite real sources, name the limits of my evidence, and flag the places where my position as a co-founder might bias the framing. Where I am making an argument that happens to favour the category my company operates in, I will say so. The goal is a book that a skeptical studio owner — exactly the kind of operator I used to be on that Saturday morning — would find useful even if they never bought a single piece of software from me.

That is the book. Three pillars, one industry, and an honest look at why generic tools keep breaking the studios that depend on them.
