The customer already bought. Why sell to them only once?
A gym spends a fortune acquiring new members. Ads, sign-up promos, trial classes. And when someone finally commits to a membership, the commercial relationship freezes right there: charge the month, then wait for the next one.
Meanwhile, that same member could buy personal training, a nutrition plan, a specialty class package, supplements, an upgrade to an annual plan. Things they want and would happily pay for. But no one offers them at the right moment, because your staff is teaching classes, not selling.
The easiest sale in fitness is the second sale. And it's exactly the one most gyms leave on the table.
What an AI agent does with your member base
At Catalizadora we build AI agents that live in WhatsApp in your brand's voice. The interesting part isn't just that they reply, but that they sell at the right moment, automatically.
An agent connected to your CRM can:
- Spot the upsell moment: when a member has been consistent for several weeks, offer personal training or a progression plan.
- Run contextual cross-sell: to someone taking strength classes, propose the nutrition package; to someone coming for cardio, the premium group classes.
- Win back the ones going cold: if someone stopped showing up, reach out with an offer to come back before they cancel.
- Upgrade the plan: offer the switch from monthly to annual with an incentive, right when the member is hooked.
- Send the payment link and close the sale inside the same conversation.
All of this without anyone on your team chasing anyone. The agent does it, logs it in the CRM, and you see the result.
The difference between offering and pushing
This isn't spam. A good upsell agent offers the right thing to the right person at the right moment. If someone has trained for three days, you don't sell them an advanced package: you support them. Cross-sell done well feels like service, not pressure. That's why it matters that the agent speaks in your brand's voice and knows each member's context.
The revenue you're not capturing
Let's use a concrete example. Picture a gym with 500 active members paying, say, $40 USD a month.
Base revenue: 500 × $40 = $20,000 USD a month.
Now suppose an AI agent gets just 10% of those members to add an extra service —personal training, nutrition, or an upgrade— at an average value of $50 USD a month.
Added revenue: 50 members × $50 = $2,500 USD a month. $30,000 USD a year.
And that 10% is conservative, because you're offering to people who already buy from you and already trust you. The second sale doesn't require convincing a stranger: it requires being present at the right moment. That's exactly what an automated agent does better than a team busy teaching classes.
How we build it: the MAGIA methodology
This isn't a generic message blaster. We follow a five-step process:
- Mapping: we identify your add-on services, your margins, and the moments where it makes sense to offer each one.
- Architecture: we design the upsell and cross-sell rules based on each member's behavior.
- Generation: we build the agent in your voice, so offering feels like supporting.
- Implementation: we connect it to your CRM and your payment system.
- Autonomy: we hand it over working, with the code and data 100% yours.
No rental, no lock-in
Many solutions charge you a percentage of every sale or an eternal monthly license. Not at Catalizadora. The code, the data, and the operation are yours from day one. No retainers, no locked-in licenses. The only recurring cost is the real operating cost —hosting and tokens— around $200 to $400 USD a month, with no markup from us.
That means every dollar of upsell the agent generates stays in your gym, not split with a platform.
What it takes to invest
The entry point is MAGIA Solo: $4,500 USD, delivered in 15 days. That's where we build the WhatsApp AI agent wired into your CRM, able to run upsell and cross-sell across your base.
For larger operations —multiple locations, finer sales logic, deeper integrations— there's MAGIA Core ($15,000 USD) and Forge ($20,000 USD, 12 weeks).
Back to the example: if the agent adds $2,500 USD a month in extra revenue, MAGIA Solo pays for itself in under two months. The rest is recurring profit.
The next step
Your members already trust you. The question is whether you're offering them everything they'd want to buy, at the moment they'd want it.
Message our AI agent on WhatsApp and feel what it's like to get the right offer at the right moment. Then, if you want one for your gym, book a call with me: https://cal.com/pablo-estrada-hlqaql.
The second sale is the most profitable one. Don't leave it on the table.
