LIVERunning in real boxes, with proven return
Never lose anyone
who wants to train at your box
We automate your box so the only thing left for you is training with people. We answer for you at any hour and hand that person over with their trial class booked.
15 minutes on a video call. We show you the assistant using your box's own data.
The problem
Your box loses someone interested almost every day
Not because you don't want to help them. Because when they write, you're coaching, closing the box or asleep. And three hours later they've written somewhere else.

How it works
Four steps, and none of them are yours
Tap each step to see what happens underneath.
Everything that comes in, wherever it comes from, lands in the same inbox. It makes no difference whether it's one in the morning, whether you're coaching or whether it's Sunday: the message doesn't sit waiting.

What it does in this step
- Brings Instagram, WhatsApp, your website form and your ads into a single inbox
- Recognises anyone who has written before and picks the conversation back up
- Tells someone interested apart from a member asking about the timetable
- Routes an existing member on without giving them the welcome pitch
It knows your rates, your schedules, how demanding your classes are and what you usually reply. It asks what a coach would ask: where they're coming from, what they're after, how long they've been training. It doesn't recite a brochure.
Under 30 seconds on average, at any hour
What it does in this step
- Answers prices, schedules, how the trial class works and what to bring
- Asks about their experience, goals and availability to know what to offer
- Treats someone with years of training differently from someone who's never set foot in a gym
- When something falls outside the script — an injury, a medical question — it hands it to you
- Speaks whatever language they write in
This is where you see it isn't a reply bot. Zunox doesn't jot a name on a list: it checks your actual calendar, decides which class suits that person, closes the booking and leaves the work done for when they walk through the door.
The booking, the record and the coach's heads-up all come out of the same conversation
What it does in this step
- Checks your calendar live and only offers slots that exist and are free
- Picks the class by level: intro if they're starting, normal class if they already train
- Closes the booking inside the conversation and files it where you see it
- Creates the record with everything they said: experience, goals, injuries and where they came from
- Tells the coach on that slot that someone new is coming, and what they should know
- If the slot fills up mid-conversation, it offers another without you stepping in
- Collects the details you need to sign them up, without asking twice for the same thing
On the day of the class they get a reminder. If they don't turn up, Zunox writes again without you doing a thing. And once the trial is over, it asks how it went and sends them the rates.
Not one interested person is left without follow-up
What it does in this step
- Sends the reminder the same day, at the hour that works
- Wins back whoever booked and didn't show, and offers them another slot
- Asks how the class went the same day, while the good soreness is still there
- Sends the rates and explains how to sign up when the moment comes, not before
- Shows you where every person stands and who is still waiting on you
Run the numbers
What does not replying cost you?
Move the sliders to match your box. The number on the right is what falls through the cracks every year.
Messages, forms and DMs from people asking about your box.
What an average member pays.
The ones left without an answer, or answered hours later.
What slips away
€22,120
in memberships that won't come through your door this year
- Sign-ups that never happen
- 2.3 a month
- In a year
- 28 members
- What each member leaves before going
- €790
We count low: that only half of those left without an answer are really lost, that one in three of those would have signed up, and that a member lasts 10 months on average.
You're already losing that money, without having hired anything.

A neighbourhood box, in Madrid
Not a pilot and not a trial: a client box where Zunox has been running from the start, with 1,151 measured conversations. Behind Zunox there are people who run a box and people who write code, and it shows in how it's built.
“I used to reply at eleven at night from the sofa. And on the days I didn't, that person never wrote again.”
What's included
One monthly fee, and two sign-ups pay for it
No long lock-in and no small print. Meta and AI usage are billed separately, as everyone in the market does.
Everything included
A setup fee and a monthly fee
We give you the figure on the call, with your box's numbers in front of us.
- The assistant set up with your prices and schedules
- WhatsApp and Instagram connected
- Trial class booking straight into your calendar
- Automatic reminders and follow-up
- A panel to see every conversation
Questions
What everyone asks us
What exactly does Zunox do in a CrossFit box?
Zunox replies automatically on WhatsApp and Instagram to everyone who asks about your box, in under 30 seconds and at any hour. It answers questions about prices and schedules, asks what a coach would ask, and books their trial class in your calendar with their record created. Then it sends the reminder and follows up.
Do I have to change software or install anything?
No. Zunox runs on the WhatsApp and Instagram you already use, and connects to whatever tool you run your classes with. Nothing to install, no system to switch.
How much does Zunox cost?
There is a one-off setup fee and a monthly fee, plus a standalone audit if all you want is the diagnosis. We give you the figure on the call, with your box's numbers in front of us: that way you can see straight away whether it adds up. You can book at zunox.es/en/demo.
Can people tell they're talking to a machine?
Zunox speaks in your box's tone and asks specific questions instead of reciting a brochure. When something falls outside what it knows — an injury, an odd question, someone upset — it hands the conversation to you rather than making an answer up.
How long does it take to get running?
One to two weeks. In the first week we collect your prices, schedules and usual answers; in the second we get it running and fine-tune it with real conversations.
Still got one? There are more answers here.
