Our work

An agency with a technological soul.

RSB grew out of multimedia engineers, a discipline that brings together technology, design and communication. That is where our way of working comes from, digital craft, where technical precision, creativity and real commitment meet in every project we touch.

We build complete digital solutions and run marketing, SEO and SEM strategies with a business mindset. We accompany each project from its definition and stay by its side long after launch, when it is time to maintain it and help it grow.

We bring in artificial intelligence and language models to build smarter, more efficient and more sustainable projects. AI doesn't replace the craft, it amplifies it.

A loose timeline.

The beginnings
Started operations

We started in Barcelona with our first digital projects for companies and brands, focused on corporate websites and bespoke development.
Early years
Websites, platforms and ecommerce

We grew into ever more demanding projects, with ecommerce, custom platforms and technical integrations that connect systems and data.
Evolution
A consolidated team

Our in-house team specialised across disciplines, from development and UX/UI through to SEO, analytics and evolutionary technical support.
Current stage
Digital AIrtisans

We added strategy, data, automation and applied AI as one more layer that amplifies the technical craft.
Today
23+ years on the road

We support our clients in defining, building, maintaining and evolving their digital projects.

More technical and strategic partner than generic digital agency.

We are a digital agency based in Barcelona with an in-house team specialised in digital strategy, web development, ecommerce, applications, SEO, analytics, automation and the support and evolution of digital platforms.

We like to describe ourselves as a technical and strategic partner. We step in where judgment, experience and real execution capability are needed, on bespoke websites, complex ecommerce, digital platforms, integrations and evolutionary maintenance, on solutions that need to keep growing after launch.

Why we work this way.

We help companies, brands and institutions define, build and evolve digital solutions that are solid, scalable and genuinely useful for their business.

We work from independence, transparency and technical judgment. We don't believe in standard solutions for complex problems, so we study each project, understand its context and propose the technology, the architecture and the approach that truly fit.

For us, technology makes sense when it is well thought out, well built and well maintained. AI, automation and data don't replace the craft, they amplify it.

Independence

We choose the technology and the architecture with no partnerships that sway the decision.
Transparency

We explain how, why and with which decisions each project is built.
Technical judgment

We design every solution so it can scale, last and evolve over the years.
Amplified craft

We weave in AI, data and automation as layers that strengthen the craft.
