Jimmy CoachCo-founded
From 
a coach’s request to a SaaS 
we co-own.
- Quentin RandisHyrox & CrossFit coach, 250+ clients
- Nazar MorozCo-founder & CTO, Jimmy Coach
A coaching platform co-founded and co-owned with a working coach: one native app for iOS and Android, and a web dashboard, live in both stores.
The request
A coach with 250+ clients asked us for his own app.
Quentin Randis coaches Hyrox and CrossFit. He was running it across WhatsApp, spreadsheets and PDFs, and losing clients in the gaps.
Before
Four tools and the gaps between them.

After, in Jimmy
One app he co-owns.

- Communityhis clients in one place
- PaymentsStripe subscriptions
- Coursesbuilt in the dashboard
The decision
So I put my own money in.
Instead of billing Quentin by the hour, I co-founded Jimmy Coach with him and paid for it myself. I've been through every cycle a founder goes through, building, raising, launching and taking it to market, and that's the experience you get when we build yours.
“I don't just build SaaS for clients, I put my own money into one.”

The product
One app for iOS and Android, and a web dashboard.
Web
The dashboard
Control of everything: workout and course builders, clients, Stripe subscriptions and revenue, in one place instead of five tools.
One coach’s dashboard: their clients, programs and revenue.
Native app · iOS & Android
For clients
Where members train, every day: today's workout in clear blocks with timers and video cues, chat with the coach, community, streaks and PRs.
Same app · coach login
For coaches
Log in as a coach and the same app turns into your controls: clients, programs, messages and payments, from the gym floor.
Three decisions we made as owners
- 01
The coach's AI, not ours.
Jimmy works with the coach's own Claude, ChatGPT or Perplexity through MCP, and a custom MCP connects any other AI. Importing a program costs the coach nothing beyond their own AI subscription.
- 02
Five things, done well.
Workouts, community, messaging, payments and courses. Jimmy isn't a feature factory; it does five things and stops there.
- 03
Built in the open, with coaches.
A release every week, a public roadmap coaches vote on, and the founders on Discord to answer them.
What we got wrong
Closing the app lost the workout.
Our first client app didn't resume a session. Now it opens on the exact block and set, with the real elapsed time on the timer.
Our first Workout Builder wasn't comfortable enough.
We rebuilt it again and again. We listened to every coach in the beta, let them vote, and shipped what helped, until it became one of the best workout builders on the market.
The numbers
Launched July 2026 · as of September 2026
100+
coaches in the first month, each bringing 2–3 clients
20–40
clients each for the biggest coaches
Jimmy Coach, in short.
Five things, done well: workouts, community, messaging, payments and courses. Clients train in one app for iOS and Android, coaches switch the same app into coach mode, and a web dashboard builds programs and tracks Stripe subscriptions and revenue. 200+ coaches were on it two months after launch.
Nazar co-founded it with Quentin Randis, a Hyrox and CrossFit coach with 250+ clients, and paid for it himself instead of billing by the hour. Gimmir built it and co-owns it.
