Corner OS — we help boxing gyms grow

We turn gyms
into fighter
factories.

Members quit because they can't see their own progress. Corner OS makes every athlete's journey visible — so they stay, refer their friends and pay happily. You run the gym. The system runs the admin.

What hurts your gym the most right now?

Why gyms lose members

Progress nobody can see is progress that quits.

Members quit silently

The #1 reason isn't price — it's invisible progress. By the time you notice the empty spot, they're gone.

Everything lives in WhatsApp

Programs on paper, attendance in memory, camps in chat threads. Nothing compounds.

Coaches drown in admin

Check-ins, plans, re-engagement — hours that should be spent coaching.

Keep just five members from quitting and Corner OS pays for itself six times over.

Everything in one system

01Members see themselves getting betterEvery athlete: style, level, goals and a visible 8-week progress line. Visible progress is why people stay.
02Know who's quitting before they doAttendance drops → flag → a re-engagement message, already drafted. You keep the member before the decision is made.
03No more Sunday-night planningWeekly plans and full 8-week fight camps, adjusted per fighter — beginner pathway to pro preparation, generated in minutes.
04Training that adapts to real lifeMembers check in daily (or connect Garmin/WHOOP) and their session adapts. A data layer no rival gym in your city offers.
05Answers at 11pm — without texting your coaches at 11pm'What do I train today?' 'Fix my jab.' A gym-branded AI corner, trained on your programs.
06An app full of reasons to come backThe magazine, the masters, the workouts — your gym's app, always pointing back to your mats.
07Weight cuts without the panic weekCut protocols, fight-week plans and fuel guidance per weight class — built in, not googled.
08Run fight nights like a promotionTickets, fight cards, weigh-ins, live results — your own shows, same system, zero extra tools.

Gym owners — the whole thing in one minute

Here's the deal,
in plain words.

Members leave when their progress goes invisible. Corner OS makes it visible — that's the whole retention mechanism, and you can see it in the live demo before paying anything.

01

What changes

  • Every member gets a visible plan and visible progress — people stay when they can see themselves getting better
  • Every athlete's journey in one system instead of WhatsApp, paper and a coach's memory
  • Fight-night tools built in: tickets, cards, results — your shows run themselves
  • Our media reach behind your gym — an 800K+ combined audience machine promoting you
02

Compared to what?

Free tier to start — set up in a day. Founding gyms lock founding terms before public pricing exists. One saved membership usually pays for the whole system.

03

Why hesitate?

No contracts, no lock-in, no setup fee. If it doesn't visibly make your gym money, you stop — and you keep everything you learned about your members.

This is for you if…

  • Members quietly leave after 3 months and you don't know why
  • Your training plans live in one coach's head
  • You want to run fight nights without drowning in spreadsheets

Not for you if…

  • Your paper system genuinely works and everyone stays
  • You have ten members and know every journey by heart

The founding deal

Corner OS plus what no tool can offer: 175+ magazine pieces, weekly coverage of UFC, OKTAGON and the big four boxing bodies, fighter stories with 30K+ reach — a media arm that points at partner gyms. Founding gyms lock founding terms.
