It looks wrong on phones
More and more customers look you up on their phone. If they have to zoom to read, they leave.
Web studio in Barcelona
We modernize websites for small and medium-sized businesses in Spain: fresh design, fast loading, mobile, bookings, integrations and AI. And before we ask you for anything, we show you your new website, for free.
Illustrative example: an outdated 2009 website turns into a modern one with bookings, WhatsApp and an AI assistant.
Sound familiar?
And you rarely find out: people don’t complain, they just choose someone else.
More and more customers look you up on their phone. If they have to zoom to read, they leave.
Every second of waiting is someone going back to Google and clicking on someone else.
Your business has improved a lot. Your website still tells the story of ten years ago.
Updating your hours or a price depends on someone who no longer answers the phone.
Forms that never arrive, emails nobody sees and customers writing after hours.
Bookings, payments, WhatsApp and your calendar: all separate, all by hand.
The good news: modernizing it is no longer a months-long project. It takes days.
See what we doWhat we do
From a complete redesign to connecting your website with your tools or adding an AI assistant. You choose where to start.
Your website as it should be today: modern, fast and built for phones. We keep what already works (your copy, your brand, your domain and your search rankings) and change everything else.
What your business needs to sell more and serve customers better, without depending on anyone for the basics.
We connect your website with the tools you already use, so bookings, messages and payments land where they belong, automatically.
We apply AI where it genuinely saves time: an assistant that answers customers using your business information, or automations that take care of repetitive work. Always with human oversight.
How we work
No commitments, no fine print. Here is the path, step by step.
Start with step 1We look at it the way a customer would, and the way Google does: phones, speed, copy, contact options and search visibility.
We prepare a real, clickable concept using your own copy and branding. Open it on your phone and show it to anyone you like.
A 30-minute video call: what you like, what you would change and what your business needs. You leave with a fixed quote.
We build the complete website and show you progress every few days. You comment, we adjust, and you approve every detail.
We launch it on your domain with no downtime and no lost rankings, connect your tools and stay available for whatever you need.
Real projects
Real websites for real clients, shown with their permission. Drag the handle to compare before and after.

Residency and citizenship agency for Paraguay
A site made with a visual website builder, redesigned from scratch in custom code. The challenge: keep every word the client had approved, and make it far more engaging and clear.
Private real-estate investment group
A precise, understated website for an investment group: three languages, an interactive market map and investor forms.
How we use AI
We design, code and test with Claude Code, Anthropic’s coding agent. It does in hours what used to take weeks, and leaves us time for what matters: understanding your business and getting every detail right.
Every website is written for your business: lighter, faster and with no plugins to maintain.
We simulate phones, slow connections and different browsers to check speed, layout and forms before we show it to you.
AI speeds up the work. Judgement, final design and how we look after you are always down to people.
Coming next: an agent pipeline on the Claude API that audits a business’s website and drafts a personalized concept in minutes, so any owner can see their new website before spending a cent.
