About us
A technical studio that’s small on purpose.
BL Diseno is Laszlo Brusa’s studio in Barcelona. We handle the technical side of businesses, from the website and its hosting to AI agent systems, with a simple idea: the person you talk to is the person who builds it.
Talk about your caseIn short
BL Diseno is a technical studio based in Barcelona, founded by Laszlo Brusa. It designs and builds websites, hosting, automations, AI agents and AI audits for companies in Spain and the rest of Europe, works in Spanish and English, sets the price in writing before starting and leaves everything in the client’s name.
Laszlo Brusa
I was born in Paris and live in Barcelona, where I study at ESADE. I build software: financial analysis applications, legal research tools and, above all, the AI agent system the studio runs on every day.
I also work on communications and branding for a law firm, which forces me to translate technical matters into language that non-technical people understand. That’s what I try to do with every client.
Why a single point of contact
At many agencies, the people who sell don’t build and the people who build don’t talk to the client. What matters gets lost along the way. Here, the first conversation, the proposal, the build and the maintenance are handled by the same person, backed by an agent system that takes care of much of the preparation and verification.
When a project needs more hands, we work with trusted professionals, always under the same responsibility and the same point of contact.
How we see the relationship
Listen before proposing
We pay attention to your actual situation and look for the solution that makes sense for both of us, not the most expensive one.
Fixed price
Scope, timeline and price in writing before we start. No open-ended hours.
Everything in your name
Code, domains, accounts and data belong to you from day one.
Growing through referrals
We’d rather have a few well-looked-after clients who recommend us than many who never come back.
