Stop losing leads after hours. ## The first message doesn't wait for office hours Someone just got served with a lawsuit. It's 10:40 at night. They search Google, find three firms, and message all three on WhatsApp. The one that replies first, confidently and in the right tone, wins the consultation. The other two answer at 9:30 the next morning, and by then no one is listening. At law firms, leads rarely get lost for lack of capacity. They get lost in minutes. And the cost of a lost lead is not small: a single contested matter or a recurring corporate retainer is worth thousands of dollars in fees. At Catalizadora we build AI agents that answer that first message instantly, at any hour, in your firm's exact voice. Not a generic chatbot reading from a script. An agent that sounds like your firm: measured if your firm is measured, warm if you serve individuals, technical if you litigate commercial matters. ## What the agent actually does This is not an FAQ in disguise. It runs the opening of your full commercial process: ### It replies in your brand voice Before we write a line of code, we map how your firm speaks. The words your partners use, what they promise and what they would never promise, the level of formality. The agent answers in that register. A client writing to a serious tax firm gets serious answers; one writing to a family-law practice gets warmth. The voice is yours, not ours. ### It qualifies the client before a lawyer is involved Not everyone who writes is a client. The agent asks what it needs to understand the matter (labor, commercial, family, tax), the urgency, and whether the case fits what your firm handles. By the time a lawyer opens the conversation, they already know who they're talking to and what it's about. No more burning billable hours screening. ### It books the consultation If the case qualifies, the agent offers real time slots and books the initial consult straight into the calendar. No more "does Tuesday work for you?" repeated twenty times a day. ### It sends the payment link If you charge for the initial consult or take a retainer, the agent sends the payment link inside the same conversation. The client pays without leaving WhatsApp, and it's confirmed. ### Everything lands in the CRM Every conversation, every client detail, every appointment and payment is logged in your CRM automatically. Your partners see the full funnel: how many wrote in, how many qualified, how many booked, how much came in. With no one typing anything by hand. ## How it compares to hiring more staff The obvious fix for lost leads is to hire a receptionist or assistant to answer WhatsApp. Let's do the math. An assistant covers a shift, say 9 to 6. The 10:40 p.m. lead is lost anyway. They cost a recurring monthly salary plus benefits. They handle one conversation at a time. And they take vacations, get sick, and resign. The AI agent answers at any hour, seven days a week, holds dozens of simultaneous conversations with no one waiting, and carries no monthly salary. At Catalizadora the agent is built once and the running cost is pass-through: roughly 200 to 400 USD a month for hosting and tokens, with no margin for us. It is not a retainer. We don't charge you per message it answers. The comparison isn't agent versus lawyer. It's an agent so your lawyers never touch a cold lead until it's already qualified and booked. ## How we build it: the MAGIA method We don't hand you a generic product with the name swapped out. We follow a five-step process: - **Mapping**: we learn how your firm sells, which matters you handle, how your brand speaks, and where leads leak today. - **Architecture**: we design the conversation flow, the qualification rules, and the integration with your calendar and payments. - **Generation**: we build the agent with your firm's voice and a knowledge layer of your services. - **Implementation**: we connect it to your WhatsApp, your CRM, and your payment gateway. - **Autonomy**: we hand it over running and self-operating. The code, the data, and the infrastructure are 100% yours. That last point is deliberate. We don't lock you into a license or a platform of ours. If tomorrow you want another team to run it, you take everything with you. ## What it costs For a firm that wants to start with the WhatsApp agent, its site, and the content engine, MAGIA Solo is 4,500 USD with delivery in 15 days. If you need something deeper, with a full CRM and custom flows, MAGIA Core is 15,000 USD. For a full operational transformation, Forge is 20,000 USD over 12 weeks. In all three cases the code and infrastructure are registered to you, and the monthly cost is only the real price of hosting and tokens. ## The client who reaches you already wants to talk The goal isn't to automate the human relationship. It's the opposite: to let your lawyers spend their time on the clients who will actually retain them, with the context already gathered, instead of answering the same "do you handle labor cases?" forty times a week. If you want to hear how your firm would sound with an agent that replies and sells in your voice, message our AI agent on WhatsApp and watch the same system we build for clients work in real time. Or book a direct conversation with me at https://cal.com/pablo-estrada-hlqaql and we'll shape it around your case. ## Preguntas frecuentes ### Does the agent give legal advice to my clients? No. The agent replies, qualifies the matter, books the consult, and collects the retainer if you set one up. Legal advice always comes from a lawyer at your firm. The agent simply prepares the conversation so your team arrives with full context. ### Does it really sound like my firm or is it a generic bot? It sounds like your firm. In the Mapping phase we capture your tone, vocabulary, and rules, and the agent answers in that register. The voice is yours; we just build it into the system. ### What does it cost and how soon do I have it? MAGIA Solo, which includes the WhatsApp agent, is 4,500 USD delivered in 15 days. MAGIA Core with a full CRM is 15,000 USD. The monthly running cost is pass-through, roughly 200 to 400 USD for hosting and tokens, with no retainers. ### Who owns the code and the data? You do, 100%. The code, your client data, and the infrastructure are registered to your firm. We don't tie you to any license or platform of ours. ### Does it work outside office hours? Yes, that's the whole point. It answers 24/7, seven days a week, and holds several conversations at once. The lead who writes at midnight gets an immediate reply instead of waiting until the next day. --- Source: https://catalizadora.ai/blog/ai-agent-brand-voice-law-firms Author: Pablo Estrada — AI Catalyst, LLC (catalizadora.ai)
