Jimmy CoachCo-foundedClients don’t just train.
They belong.
Jimmy is the retention platform for modern fitness coaches — the “Skool of Fitness.” A whole platform: two native mobile apps and a web dashboard, with programs, community, messaging, payments and courses inside. We co-founded it and built all of it, end to end.

Inside the app
Not a management tool. A place clients belong.
Most coaches run their business across WhatsApp, spreadsheets and PDFs — and lose clients in the gaps. Jimmy pulls it into one branded app where clients get their program, track every session, talk to their coach, and belong to a community.
Jimmy was co-founded with a working coach — Quentin Randis, who has coached 250+ clients in Hyrox, CrossFit and functional fitness. He brought the coaching judgment; we brought everything else: product, design and engineering, from an empty repository to the App Store. Not billed by the hour — built as owners.
“Not a disguised web wrapper or a vibe-coding project. It’s a high-performance mobile app built by engineers, designed for stability and scalability.”
One platform, three surfaces.
Not a website with a mobile view. Two native apps and a web dashboard on one shared platform — each surface built for how it is actually used.
The client app
Where members train, every day. Today’s workout in clear blocks with timers and video form cues, chat with the coach, the community feed, streaks and PR history — under the coach’s own brand, their logo and colors on the home screen.
The coach app
The business in a pocket. Coaches program workouts, answer clients, drop announcements to the community and watch payments come in — between sessions, from the gym floor, not from a laptop.
The dashboard
The heavy lifting: the workout and course builders, client management, Stripe subscriptions and revenue analytics. Everything a coaching business runs on, in one place instead of five tools.
One design system, one API, one data model underneath — which is how a small team ships a new feature every week across all three surfaces without them drifting apart.
Everything a coaching business runs on.
Two sides in one product: the app clients train in, and the tools coaches run their business with.
Workout builder
EMOM, AMRAP, circuits and strength — structured blocks with video form cues, written the way the best coaches actually program.
Community feed
Skool-style posts, reactions and group challenges that turn a client list into a place people belong.
Messaging
1:1 and group chat with voice notes, photos and video — so coaching stops living in WhatsApp.
Payments & subscriptions
Stripe billing built in: recurring plans, automated charges and revenue analytics. No chasing invoices.
Courses
Modules, lessons and full programs packaged next to the training — knowledge the coach sells, not just sessions.
Progress & PRs
Lifts, benchmarks, streaks and graphs — clients see themselves getting better, which is why they stay.
Video exercise library
Every movement with a demonstration, ready to drop into any block of any workout.
Their own branded app
Each coach’s logo and colors — their app on the client’s home screen, not another account in someone else’s tool.
From an empty repo to the App Store.
Built the way we build for clients: senior team, honest scope, working software early and often.
An empty repository
Co-founded with a coach. No code, no designs — a bet that independent coaches deserve better than PDFs and spreadsheets.
Design system & platform
One design language, one API, one data model — built once, powering every surface.
Two apps + web
Native client and coach apps and the web dashboard, built in parallel by the same small team.
App Store, then traction
Live in the App Store, 300+ users in the first month — and a weekly release cadence ever since.
Because we run Jimmy as owners, every hard problem — App Store review, Stripe billing edge cases, chat at scale, keeping two native apps in lockstep — is a problem we have already solved for ourselves before a client ever pays us to solve it for them.
The result
active coaches on the platform
users in the first month after launch
expert workouts, ready on tap
native apps — client and coach — plus web
Live in the App Store, growing week over week — and still built and run by the same team you would be working with.
