FitBook

What FitBook does

FitBook, operated by Fitness Booking, Inc. (a privately held Delaware corporation), is a web-based SaaS automation platform that monitors boutique fitness studio class registration schedules and executes bookings the moment registration windows open. The product is built on credential-based integration with two upstream studio platforms — Mariana Tek and MindBody — which together power most boutique fitness studios in the US. FitBook submits user credentials on behalf of subscribers at sub-second latency, uses AES-256 encryption with separated keys for credential storage, and supports recurring weekly schedule automation so that the same class can be booked automatically each week.

The platform is sold as a self-serve consumer subscription with two tiers: Basic at $19.99/month (1 studio, 2 schedules) and Premium at $39.99/month (unlimited studios, unlimited schedules, priority booking, premium support). Acquisition is product-led: users discover FitBook through organic SEO content (blog posts on booking frustration), sign up for a 3-day free trial without a credit card, connect their studio credentials, and convert to paid monthly billing processed through Stripe. The go-to-market is entirely direct-to-consumer via fitbook.io with no app, no retail, and no reseller channels. The customer base is described qualitatively as "hundreds" of individual fitness enthusiasts across US cities including NYC, LA, Chicago, Austin, and Seattle, with no enterprise or B2B relationships disclosed.

Financially, FitBook appears to be founder-owned and bootstrapped: no funding rounds, no headcount, and no revenue are disclosed in the source material. The product is actively operating with recent content publication (January 2026) and updated terms of service, suggesting early-stage traction rather than maturity. Strategically, the company has staked its differentiation on millisecond-speed booking execution and platform integrations, with a stated roadmap to add additional studio platforms beyond Mariana Tek and MindBody.

Core offering

FitBook is a web-based SaaS that automatically books boutique fitness classes the moment registration opens across studios powered by Mariana Tek and MindBody. Users connect their studio credentials, set class preferences once, and the system executes millisecond-speed bookings on a recurring weekly schedule. The service is offered to individual fitness consumers via two monthly subscription tiers.

Product overview

FitBook is a single unified automated fitness class booking service consisting of two pricing tiers: Basic ($19.99/month) and Premium ($39.99/month). Both tiers provide automated booking that secures class spots the moment registration opens, but Premium offers unlimited studios/schedules with priority support while Basic is limited to 1 studio and 2 schedules. The service integrates with Mariana Tek and MindBody platforms to book classes on users' behalf without manual intervention.

Expansion highlights4 records

Others

• Calendly: Calendly is a mainstream scheduling automation platform widely adopted across professional services. While it does not integrate with Mariana Tek/MindBody or automate class registration specifically, it represents the broader 'automate the booking moment' category and could expand into fitness with capital.
• TrueCoach: TrueCoach is a personal trainer coaching platform with scheduling and programming tools. It is an adjacent enablement player in the boutique and independent trainer segment where FitBook's users operate, and a candidate buyer or partner for extending FitBook's automation into coaching workflows.
• Trainerize: Trainerize is a personal training and fitness coaching platform serving trainers and their clients with scheduling, programming, and habit tracking. It is an adjacent player in the boutique-fitness tool stack and competes for the same trainer/studio customer relationship that FitBook depends on for distribution.

Broad incumbents

• Gympass: Gympass is a corporate wellness platform giving employees access to a network of gyms and studios. It competes for the same boutique fitness enthusiast wallet and bundles class booking that could, with time, replicate FitBook's automation value.
• MindBody: MindBody is the underlying studio management platform FitBook integrates with and one of the two 'core' integrations powering the service. It is a broader incumbent offering scheduling, payments, and marketing software to tens of thousands of fitness and wellness businesses — and could trivially ship a native 'book at registration open' feature that competes directly with FitBook.
• ClassPass: ClassPass (which acquired MindBody) is a broad consumer fitness subscription platform reaching the same boutique fitness attendees FitBook serves. While not a direct automation competitor, it competes for the same user's wallet and increasingly bundles booking/availability features that overlap with FitBook's value proposition.
• Mariana Tek: Mariana Tek is the other core integration partner FitBook relies on, providing boutique studio software for brands like Brrrn, Y7, and others. As a vertically specialized incumbent in the boutique segment FitBook targets, Mariana Tek is the most natural party to either partner deeper or launch a competing native feature.

Direct peers

• Glofox: Glofox is a fitness studio management platform (scheduling, memberships, payments) serving boutique gyms and studios. It is a direct peer in the studio-side tooling layer that FitBook integrates against, and a likely target for FitBook's next integration given its boutique-segment focus.
• Walla: Walla is a boutique fitness studio software platform offering scheduling, memberships, and client management. It overlaps directly with the studio-platform layer FitBook relies on and represents both a future integration target and a competitor should it expand into consumer-side booking automation.

Emerging players

• Acuity Scheduling: Acuity Scheduling is a broadly used appointment and class-booking SaaS powering many smaller fitness and wellness businesses. While not specifically aimed at boutique-studio registration speed, it competes for the same user need (scheduling/booking automation) and could be extended by studios to address the registration race.
