Marketing agencies: handle WhatsApp 24/7 without hiring more staff

Your agency loses prospects after hours. An AI agent handles WhatsApp 24/7 in your voice, qualifies leads, books meetings and charges, with no new hires.

The lead that goes cold while your team sleeps

A marketing agency runs on prospects. But prospects don't message during office hours. They message at 9 p.m. after seeing an ad, or on a Saturday while comparing three agencies at once. By the time someone on your team opens WhatsApp on Monday, that prospect has already talked to a competitor who answered first.

The problem isn't the quality of your work. It's your response window. And hiring someone to cover WhatsApp 24/7 isn't realistic: it means shifts, salaries, training and turnover. For a boutique agency, that fixed cost eats the margin.

At Catalizadora we build something different: an AI agent that handles WhatsApp in your agency's voice, around the clock, without a single new hire.

What the agent actually does

It's not a menu or a "press 1 for sales." It's a real conversation. The agent:

Replies instantly, in your tone

If your agency sounds direct and technical, it replies that way. If it sounds warm and consultative, it replies that way. The buyer doesn't feel like they're talking to a generic bot, but to your brand.

Qualifies the prospect before a human sees them

It asks what your team would ask: rough budget, type of project, timeline, channels they already invest in. It separates the curious from the real buyer. Your team stops burning hours on calls that were never going to close.

Books the meeting

When the prospect is ready, the agent proposes times and drops the meeting on the calendar. No "does Tuesday work?" back-and-forth that kills momentum.

Sends the payment link

For deposits, onboarding retainers or fixed packages, the agent sends the payment link inside the same conversation. The prospect pays without switching channels.

Logs everything to your CRM

Every conversation is recorded: who wrote, what they asked, what stage they reached. Your team opens the CRM in the morning and sees exactly where to pick up. Nothing gets lost in a chat thread or in the head of whoever happened to answer that night.

It never leaves anyone waiting

The modern buyer doesn't forgive silence. A "I'll get back to you tomorrow" carries more weight than it seems: it signals they're not a priority. The agent removes that silence entirely, and that alone shifts how your agency is perceived next to the competitor who took three hours to reply.

An agency recovers leads it used to lose

Let's look at numbers, without inventing case studies. If your agency gets 60 new WhatsApp messages a month and 40% arrive outside office hours, that's 24 conversations that today wait hours or go cold. If you recover half of those with an instant reply, that's 12 extra qualified prospects a month that simply didn't exist in your pipeline before.

The traditional alternative is hiring a support person. Between salary, benefits and tools, that runs several thousand dollars a year, plus the time to train them and the risk they quit. The AI agent doesn't quit, doesn't get tired and doesn't need re-onboarding every six months.

How we build it: the MAGIA method

We don't hand over a template. We follow a five-phase process:

  • Mapping: we learn how your agency sells today, what prospects ask, and where deals fall through.
  • Architecture: we design the conversation flow and the qualification rules.
  • Generation: we build the agent in your brand's voice.
  • Implementation: we connect it to your WhatsApp, calendar, payments and CRM.
  • Autonomy: we hand everything over so it runs on its own.

The entry product is MAGIA Solo: 4,500 USD, delivered in 15 days. It includes the agent, its integration and a setup that's ready to operate.

What you keep (and what we never lock you into)

Here's a difference that matters: the code, data and infrastructure are 100% yours. No retainers, no locked licenses. We don't charge you a monthly fee to use your own agent.

The only recurring item is pass-through operation —hosting and tokens— roughly 200 to 400 USD a month, billed at cost with no margin for us. If tomorrow you want to move everything to your own server, you take the code and go.

Compare that to most chatbot platforms: you pay an open-ended monthly subscription, your data lives in their cloud, and the day you stop paying, you're left with nothing. Here it's the opposite. You pay once to build it, and it's yours.

Which agency size this makes sense for

If you're a freelancer with three clients, you can probably reply yourself. But if you already have a steady flow of WhatsApp prospects, a team distracted by support fires, or you lose leads to slow replies, the agent pays for itself fast.

It also works if you manage WhatsApp for your own clients: you can offer the agent as an add-on service from your agency, built on the same foundation. For many agencies that's the most interesting angle: you stop treating it as an internal tool and turn it into a new revenue line you sell to your clients.

The mistake of waiting for the "perfect moment"

The most common objection we hear is "I'll look at it later, when we have more volume." The problem is that every month you postpone, you keep losing the leads that arrive after hours. It's not a cost that shows up on your P&L, but it's there: it's the conversations you never answered. The agent doesn't need huge volume to justify itself; it only needs you to be losing even a few good prospects a month.

The next step

If your agency loses prospects by not answering in time, an AI agent on WhatsApp is the most direct way to close that leak without hiring anyone. It replies 24/7, qualifies, books, charges and logs everything to your CRM.

Message us on WhatsApp and let the agent itself show you how it talks, or book a call with us here: https://cal.com/pablo-estrada-hlqaql. In that conversation we'll map how your agency sells today and how fast we can get your agent answering.

Frequently asked questions

Does the agent replace my support team?

No. It replaces the wait. It answers, qualifies and books after hours and during demand spikes, then hands your team only the real prospects, with full context already in the CRM.

How much does it cost and how fast is it ready?

MAGIA Solo costs 4,500 USD and is delivered in 15 days. It includes the agent and its integration to WhatsApp, calendar, payments and CRM, ready to operate.

Is the agent mine, or do I pay a monthly fee?

It's 100% yours: code, data and infrastructure. No retainers or locked licenses. The only recurring item is pass-through operation (hosting and tokens), about 200 to 400 USD a month, at cost.

Can it speak in my agency's specific voice?

Yes. During the Mapping phase we study how your agency sells and build the agent with your tone, your qualification questions and your closing rules.
