We don't build pages.

  • 100% custom systems
  • No templates, no builders
  • 3 rounds of revisions included

The ground has shifted

Today, anyone can build a decent page with AI. A system that charges, books and controls inventory, they can't.

Loose design stopped being a differentiator: any template or assistant produces something presentable in minutes. What's still hard — and why it still pays off — is the engine behind it: real business logic, payments that add up, inventory that doesn't lie, and a notification on your phone every time a sale comes in.

Who it's for

Built for businesses that already sell and want to run better.

Every industry has its own bottleneck. These are the ones we solve most.

Tours and activities

Bookings by date and capacity, deposit payments and automatic tickets.

Hotels and vacation rentals

Digital guest guide, tour sales and Telegram alerts.

Deposit-based appointments, per-artist commissions and synced calendar.

Real estate

Capabilities

What always comes included.

These six things aren't add-ons or paid modules: they're the baseline every system ships with.

Actually responsive

Tested on real iPhones and Android devices, not just a shrunk browser window. Every screen is checked at 390 px before delivery.

Measured speed

Custom code, optimized images and GPU-driven animation. The system loads in under 2.5 s on mobile data.

A panel you're not afraid of

Edit prices, text, photos, availability and inventory without calling anyone or breaking the design. Recorded training included.

SEO + AEO

Beyond ranking on Google, we prepare your content and structured data so assistants like ChatGPT, Gemini or Perplexity understand your business and recommend it.

Domain and hosting, handled

We purchase and manage them for you every year, registered with your details as the owner. No renewals or settings to worry about.

Real integrations

Your system connects to what you already use: card payments, Telegram or WhatsApp alerts, email, spreadsheets and third-party APIs.

Real cases

Four systems in production.

Not projects under construction: things working for a real business today. All of them are live — go check them out.

Ticketing system

Island Adventures Mexico

Ticketing system for tours: every sale generates its ticket and fires an automatic Telegram alert to the team. Manual confirmation tracking is over.

The model

Build + annual hosting.
No surprises.

You pay once for the build and, each year, for the hosting and domain that keep your site online. So you always know exactly what you're paying for and why.

Lead-capture landing page

One page built to turn visits into clients, connected to WhatsApp.

From $3,500 MXN

Custom web system

Public website + admin panel + your operation's logic.

From $13,000 MXN

Point of sale, bookings and payments

Modules added to the system based on what your business needs.

Quoted within the system

Annual hosting and domain

Hosting (approx. $4,500) + domain (approx. $800). We manage both for you.

Approx. $5,300 MXN / year

Maintenance

Optional: backups, security updates, direct support and minor improvements.

Quoted based on your system

Hosting and domain, in your name, hassle-free. We purchase and renew them every year on our platform, registered with your name, email and contact details as the business owner. We handle setup, certificates and renewals. They're not included in the build price.

Payment terms. 50% deposit and 50% on delivery. Monthly installments can be arranged for larger projects.

Revisions. Three rounds of revisions included; from the fourth round on, each round is billed and you're notified before it starts.

Process

Four steps, zero surprises.

First we listen to how your business operates. Then we propose. Nothing gets charged or built until you have it in writing.

  1. 01

    Assessment

    A 20-minute call and a short questionnaire. We understand your operation, your margins and where your time goes before proposing anything.

    20 min
  2. 02

    Written proposal

    Scope, modules, timeline, investment, hosting and domain. You approve, and we start. Whatever isn't in the proposal doesn't show up as an extra later.

    48 h
  3. 03

    Staged build

    First the design: you see it, approve it, we adjust. Then the system, with partial deliveries so you can test it as it's built. Three rounds of revisions included.

    7 days – 8 weeks
  4. 04

    Delivery and launch

    Your system live in production, with domain, email, WhatsApp, analytics and backups. I'll walk you through the panel, and you keep direct WhatsApp support.

    Ongoing

We also do

Branding, social and advertising.

The studio still works on brand identity, social content, photography, print design and Meta and TikTok campaigns for businesses that already have their system running. That's the layer that brings people in; the system is what takes care of them.

Let's talk branding and social

Questions

What people almost always ask before we start.

How much does a custom web system cost?

A custom system —public website, admin panel and your operation's logic— starts at $13,000 MXN. The final price depends on what you need: bookings, online payments, inventory, point of sale, integrations or multiple languages. A lead-capture landing page starts at $3,500 MXN. Hosting and domain are not included: they're paid separately each year. The quote is delivered in writing, free and with no obligation. Quotes for international clients can be issued in USD.

How do hosting and domain work?

We purchase, set up and renew your site's hosting (approx. $4,500 MXN) and domain (approx. $800 MXN) every year. Both are registered with your name, email and contact details as the business owner, in case any claim ever needs resolving. On top of that you can add a maintenance fee covering backups, security updates, direct WhatsApp support and minor improvements; it's quoted based on your system.

How long does the build take?

A lead-capture landing page is ready in 7 to 10 business days. A system with an admin panel, bookings, payments or point of sale takes 4 to 8 weeks, with partial deliveries so you see it working from the first stage.

Can I manage the system myself?

Yes. Every system includes an admin panel to change prices, text, photos, availability and inventory without touching code. Delivery includes recorded training and WhatsApp support.

What is a point of sale, and how does it help my business?

It's the system where you record every charge and get control of your operation: daily sales, average ticket, inventory, costs, cash-outs and reports by period. It runs on tablet or computer, works offline and syncs once the connection is back.

Do you work with businesses outside Cancún and Isla Mujeres?

Yes. We work with businesses across Quintana Roo in person, and with clients from the rest of Mexico and abroad remotely, by video call and WhatsApp.

Will my site show up on Google and in AI assistants like ChatGPT?

Yes. Every project ships with traditional SEO (titles, metadata, speed, sitemap and structured data) and AEO signals: clear, citable content, FAQs marked up with schema, and business data AI assistants can read — so they can find and recommend you.

How do payments work, and what if I need more changes?

The general structure is 50% deposit and 50% on delivery; monthly installments can be arranged for larger projects. Every project includes three rounds of revisions. From the fourth round on, each round is billed and you're notified before it starts.

Let's start

The assessment is free.
The system comes after.

Tell me how your business runs today and what's holding it back. I'll tell you clearly which system fits, what it costs to build, and what annual hosting runs — in writing, no obligation.

I answer myself, not a bot. Monday to Saturday, 9:00–19:00 (Cancún time, UTC−5).
