Struct Club

Struct Club develops software for instructors and operators of music-driven group fitness classes. Its debut product is an iOS application that lets indoor cycling and other music-inspired coaches combine playlists, movements, intervals, and cueing notes in a single place so that a class can be planned and then run from the app. The product works across iPhone, iPad, and iPod Touch and can be cast to Apple TV, and it connects to Spotify or Apple Music for playlists.

The platform has two broad sides. Instructors who build classes from scratch use class design tools to tag and organize songs, choreograph cues to the beat, and rely on features that auto-sort songs and flag reused tracks to reduce rework. Instructors, studios, and facilities that want to save programming time can instead start from ready-made class templates that bundle a workout, a playlist, and the accompanying cues. Members can share classes one-to-one or with a group, which is positioned at studio owners, club managers, and franchisors who want to distribute programming across their instructor base. Creators can audition classes to be featured and paid, and the company also markets premium services for studios and clubs that automate programming workflows.

Founding story

Struct Club was founded in April 2018 by Amira Polack during her final semester at Harvard Business School. Polack, a certified indoor cycling instructor and an experienced enterprise technologist, said she was frustrated by how analog and time-intensive class preparation was, spending hours scribbling notes and memorizing playlists, and found that colleagues shared the same problem of wanting to annotate key moments in a playlist and be ready to teach.

Business model

Struct Club sells consumer-style subscriptions to individual instructors and studios for access to its class creation and template library, and offers separately marketed premium services for studios and clubs. Instructors whose classes are featured can earn money from the programming they create.

Recurring subscription memberships. The Struct Club Membership is priced at $14.99 per month or $129.99 per year upfront (a stated 27% saving, equivalent to $10.83 per month). The Instructor Membership is priced at $15.99 per month or $129.99 per year upfront (a stated 32% saving, equivalent to $10.93 per month). Gift cards for the Instructor Membership are also sold, and the site operates a cart. Premium offerings for studios and clubs are sold through direct contact.

Traction

The company markets a subscriber membership base of coaches and brands and publishes an ongoing series of member profiles and podcast episodes featuring instructors, with entries dated through September 2026. It has secured industry partnerships, including with Shimano Indoor Cycling and WIFA, and completed several accelerator programs.

Latest developments

Company materials reference a partnership with Shimano Indoor Cycling to launch at-home rides choreographed to music, continuing publication of member and podcast content through September 2026, and subscription tiers covering both a general Struct Club Membership and an Instructor Membership with gift card purchases.
