Common problems in fitness businesses

Class booking chaos

Members double-book, no-show or fight for spots because scheduling runs on spreadsheets, DMs and outdated apps.

Membership & billing leakage

Failed payments, forgotten renewals and manual freezes quietly drain 10–20% of recurring revenue every month.

High member churn

Without onboarding, progress tracking and re-engagement, new members quit within 90 days before they see results.

Front-desk overload

Staff spend hours answering the same questions about pricing, timetables and freezes instead of coaching.

No unified member view

Attendance, payments, PT packages and progress live in separate tools, so nobody sees the full member story.

Weak lead follow-up

Trial and enquiry leads go cold because there is no automated nurture from first click to first workout.

What we build

An end-to-end member operating system — from first enquiry to long-term retention.

Membership platform

Plans, freezes, upgrades, contracts and recurring billing with automated dunning.

03

Member app & portal

Branded member area for bookings, progress, check-ins and workout / nutrition plans.

Automated retention coach

Detects lapsing members from attendance drops and triggers personalised check-ins, offers and re-booking prompts.
