Customer story · Boutique fitness Multi-studio rolloutL Catterton-backedExisting platformsNo migrationEngageOS + InsightsOS At a glance ## Results across the program. Figures are rounded and slightly adjusted to protect client confidentiality. Nearly 3,000 class bookings from matched sends in one month. ~$45K in estimated incremental revenue in the month, with auto-pay renewals excluded. More than 2× the audience during the scale test, with booking rate up ~0.5 percentage points. Members booked at roughly 18%, about 6× the traditional lapsed-member flow. Estimated return of ~10× software cost in month one, including ~5× on one-off purchases alone. The challenge ## Reach was not the problem. Precision was. \[solidcore\] runs Utilize across a growing studio network. Its traditional lapsed-member flow could not see which class actually had an empty seat. Its scheduling platform held the schedule and its marketing tools could deliver the messages; the missing piece was deciding whom to reach for each specific class before the seat expired. The solution ## The missing decision layer. Utilize, an EngageOS module, watches the class schedule for seats unlikely to fill soon. It scores members and prospects on their likelihood to take a particular seat, then sends small, matched campaigns through \[solidcore\]'s existing marketing platform. Its scheduling platform stays the system of record. No migration, new email tool, or engineering lift. Module results ## What changed.

Architecture ## A closed loop on the existing stack. 1. Step 1 Existing scheduling platform (system of record: appointments, memberships, check-ins, payments, cancellations, logged in real time) 2. Step 2 Utilize in EngageOS (spots classes unlikely to fill soon and matches each seat with members and prospects most likely to book it) 3. Step 3 Existing marketing platform (sends small, matched campaigns through the existing channel; no new email tool or engineering lift) 4. Step 4 Scheduling platform again, loop closed (the booking lands back in the system of record) Want to learn more? ## Explore Growth Minded for your company. Book a demo.
