Let's start with the number, no detours
The question every law firm partner eventually asks is simple: what does this cost me, and from when does it pay for itself? Let's go straight to it.
At Catalizadora, an AI agent on WhatsApp for a law firm ships under a clear package. The entry one, MAGIA Solo, costs 4,500 USD once and is delivered in 15 days. That includes the agent that answers 24/7 in your firm's voice, qualifies the client, books the consult, sends the payment link and logs every conversation into your CRM.
After delivery there is no retainer. The only thing you pay is the real operation: hosting plus the tokens the agent consumes while conversing. In a typical firm that runs between 200 and 400 USD a month, and you pay it at cost, with no margin for us. That pass-through is transparent: you see exactly where every dollar goes.
If your firm is larger, has several practice areas, or needs integrations with systems you already use, the MAGIA Core (15,000 USD) and Forge (20,000 USD over 12 weeks) packages extend the scope. Most firms start with Solo.
What you do NOT pay (and what you do pay under other models)
Here is the difference that changes the math. The code, the data and the infrastructure end up 100% in your firm's name. No monthly locked-in license, no "professional plan" that creeps up in price every year, no hostage situation.
Compare the two paths:
| Subscription chatbot platform | Agent built by Catalizadora | |
|---|---|---|
| Upfront payment | Low or zero | 4,500 USD once |
| Monthly payment | 100 to 500 USD/mo, rises with usage | Operation only: 200-400 USD/mo at cost |
| Code owner | The platform | Your firm |
| If you stop paying | The bot shuts off | It keeps running, it's yours |
| Voice and legal judgment | Generic template | Tailored to your firm |
A subscription that looks cheap in month one becomes, over three years, thousands of dollars paid for something that is never yours. With an asset you own, you pay once and the recurring cost is only what it actually consumes.
The math on when it pays for itself
No invented metrics are needed to see the point. Let's run a conservative calculation with your own numbers.
Suppose the first consult at your firm is paid. Use the average ticket of your most common area; many firms charge an initial consult in the 50 to 150 USD range, and a case that comes in is worth far more. Now think about how many prospects message you today after hours, on weekends, or while the team is in a hearing, and don't get a timely reply.
If the agent recovers even one paid consult a week that slips away today, within a few weeks it has already covered the monthly operation. If it recovers one real case a month, it comfortably recoups the initial 4,500 USD. We're not promising figures: we're saying the threshold for it to be worth it is very low, because the agent works in the hours when nobody answers today.
"But could a bot give a legal client the wrong impression?"
That's the honest objection. The answer depends on how it's built. A rigid button menu does give the wrong impression. An agent that converses in your firm's voice, with a professional tone, asks the right questions and knows to say "an attorney will review this" when appropriate, gives exactly the opposite impression: that of a firm that responds fast and seriously at any hour.
We configure it not to improvise on sensitive matters. In legal work, that is deliberate: the agent gathers the details, gives no advice it shouldn't, and hands the case to the attorney with full context ready.
Think of it the way you'd think of a sharp intake paralegal who never sleeps. It doesn't argue the case; it makes sure the right cases reach the right lawyer, fully prepared, while the wrong ones never waste a billable minute. That alone changes the economics of your front door.
Why our model costs what it costs
We are not an agency with an army of people billing hours. We are an AI-native agency: we build fast, with methodology, and we deliver an asset. That is why the entry package is 4,500 USD and not five figures like a traditional consultancy, and why the monthly operation is two to four hundred dollars and not thousands.
We follow the MAGIA methodology: Mapping how cases come in today, Architecture of the agent, Generation in your voice, Implementation in your WhatsApp, and Autonomy, where it runs on its own and in your hands. In 15 days you go from losing prospects at dawn to having an asset that works for your firm without rest.
So, is it worth it?
It's worth it if your firm receives inquiries on WhatsApp and today loses some by not replying in time. With an entry cost of 4,500 USD, full ownership of the code, and an operation of 200 to 400 USD a month, the threshold to recoup the investment is low and the asset is yours forever.
The best way to decide is to see it working. Message us on WhatsApp and let the agent handle you the way it would handle your next client; you'll understand the value in the first conversation.
