The lead you do not wait on is the lead you do not lose. ## The prospect messages at 10pm and nobody answers Look at your gym's conversations. Most come in after hours: at eleven at night after someone decides "Monday I start", on Sunday while scrolling vacation photos, at six in the morning before work. By the time your front desk opens, that message is eight hours cold and the person already signed up at the gym next door, the one that answered. This is not a problem with your team. It is a problem with hours. Your front desk serves whoever is at the counter and cannot live on the phone. The result repeats every week: prospects who came in from your Instagram campaign, knocked on the door via WhatsApp, and went cold because nobody was on the other side. At Catalizadora we build AI agents that close that gap. An agent that lives in your gym's WhatsApp, replies in seconds at any hour, books the trial class straight into your calendar and sends the membership payment link. Every conversation lands in your CRM without anyone typing it. ## What the agent actually does The agent is not a menu or a "press 1" tree. It talks in your brand's voice, the way your best salesperson would on a good day. ### Answers with your real information Class schedules, plan prices, whether there is parking, what the membership includes, how long the spin class runs. The agent knows your gym because we load it with your information, not generic replies. Ask about the quarterly plan and it answers the quarterly plan price. ### Books the trial class This is where the client is won or lost. The agent offers open slots, confirms the one the person picks and leaves it booked. No back-and-forth of "let me check and get back to you". The prospect goes from curious to committed in the same conversation, while they still want it. ### Sends payment and logs everything When the person decides to join, the agent sends the membership payment link. And whatever happens, every detail of the conversation stays in your CRM: phone, which plan they want, whether they came from Instagram or a flyer, where they left off. Your team opens the CRM on Monday and sees who is hot, not an inbox of unread messages. ### Covers the dead hours where you lose the most The hours your front desk does not cover are exactly the highest-intent ones: night, early Monday morning, Sunday afternoon. That is when people decide to change their life and go looking for a gym. The agent is awake in that exact moment, when motivation peaks and the competition has its chat turned off. It captures the prospect the second they are most willing to commit, not eight hours later when the urge has passed. ## The comparison that matters Put the numbers on the table. A front-desk hire costs you a salary every month, works eight hours, takes breaks, gets sick and cannot handle two chats at once. At best they cover a third of the day. An AI agent works 24 hours, 365 days, handles ten conversations at the same time without anyone waiting, and does not burn out in January when the new-year resolution wave hits. It does not replace your team: it frees them from answering the same thing a hundred times so they can focus on the people already on the floor. At Catalizadora the agent is built once. MAGIA Solo costs 4,500 USD and we deliver in 15 days. There are no retainers or monthly licenses locked to us: operation runs 200 to 400 USD a month in hosting and tokens, a direct pass-through cost with no margin for us. Compare that to a part-time hire just for chats, where that same spend repeats every month forever and still does not cover the nights. ## Why a gym specifically The fitness business is decided on impulse and on speed. People do not research gyms for weeks; they decide in a moment of motivation and go to the first one that makes the next step easy. Whoever answers fast and books on the spot wins. Whoever says "email us and we'll reach out" already lost. Your demand is also not flat. It spikes hard in January, in September after the holidays, every Monday. A human desk gets buried right when there are the most prospects. The agent scales on its own: ten chats or a hundred, it answers just as fast. ## How we build it We follow our MAGIA method: Mapping how your client arrives and decides, Architecture of the agent and its integrations, Generation of the voice and flows, Implementation in your WhatsApp and CRM, and Autonomy so it runs on its own. In 15 days your gym has a salesperson that never sleeps. One thing that sets us apart: the code, the data and the infrastructure are 100% yours. We do not rent you a platform you cannot leave. If tomorrow you want to move everything elsewhere, you take it all. No lock-in. ## The next step Message Catalizadora's AI agent on WhatsApp and see for yourself: ask about schedules, ask to book, watch how it answers.
