For your members
One simple app onboarded in minutes, in your gym's brand. One button, today's session. Wearables, booking, community, and their coach, all in one place. Body, mind, and spirit, built in.
Capabilities
Whatever your fitness business needs, the system does it.
Marrow is the operating system your fitness business runs on. We build the parts you would rather not touch, keep them running, and grow them with you. Members see one simple app. You see everything behind it.
Built now The core platform is built and you can walk through it end to end.
Built on request Scoped in your diagnostic, built in your brand, actively shipping.
What the system covers
One system, three people it takes care of.
Members only ever touch the simple app. Coaches see who needs them first. You see everything behind it. The same machine, shown three ways.
For your coaches
A roster with a weekly check-in that tells the coach who to reach first. A program builder, multi-coach teams on one client, verified credentials, and more ways than one to earn. When a coach leaves, the members stay with you.
For you
One console across every coach and every location. Revenue, coach splits, retention signals, billing, and payouts, with your brand on the app. We build and run the parts you would rather not touch.
What Marrow runs for your business
Run. Grow. Operate. One machine.
Your members only ever touch the first one. You get all three.
Run
The simple member app
One screen for your members, in your gym's brand. Workout, nutrition, and biofeedback in one place. One button, go.
Grow
Your site and your leads
A branded site and a place on the discovery map that send new members your way, plus the marketing and the AI ad factory behind it.
Operate
The owner's controls
One screen for revenue, coach splits, retention, and locations. The learning hub and certifications live here too.
You set it up yourself from simple menus. Nothing here is custom built. See the memberships.
Problem to solution
You have the problem. The system has the part that solves it.
Whatever you run, the build lands on one operating system. Here is that system by the problem it solves, platform-led, with the done-for-you build as the way you get it.
Members drop off and drift away
Member experience
One simple app onboarded in minutes. One button, today's session. Wearables, booking, community, and a weekly check-in that tells the coach who to reach first. Body, mind, and spirit, built in.
Too many clients to track
Coaching operations
A roster with a needs-review queue, a program builder, multi-coach teams on one client, verified credentials, and more income streams. The data stays with the gym when a coach leaves.
Cannot see the whole business
Owner and multi-location
One console across every coach and every location. Per-coach splits, billing, payouts, the gym-branded app, and a network structure for franchises and aggregators.
Leads come in and never convert
Growth and marketing
Landing pages and the discovery map are standard. The AI front desk, reputation engine, content engine, and trial nurture are built and run for you, sold on recovered dollars.
Stuck on a tool you hate
Migration and back office
Bring your members and their history across from your old tools, or run Marrow on top of what you use today. Failed payment recovery, an ops assistant, and a recovered revenue dashboard, all inside your own account.
Whose data is it, really
Trust and anything custom
Verified coaches only, per-tenant isolation, no-index authenticated surfaces, and a documented exit. Custom apps, web, integrations, and tools built in your brand. You own your data.
These are the common shapes, not the limits. If your business needs something none of them name, it very likely still fits. Ask us and we will show you how the platform handles it.
Custom anything, and it stays yours
You own it. We do the heavy lifting.
An operating system built and run for fitness businesses. Your data and accounts are yours, payments run on Stripe, and you are never locked out. Your own Claude connects to your account and drafts on your own content, a human coach drives every interaction, and you decide whether it is on. Each one runs a job end to end, not a single feature: it owns its job all day, every day, without being asked. See what your Claude can do.
