Digital studio
Founded in Catalonia
The studio

Quatre Rius is a digital studio founded by Atzarí Surinyach Corominas and Ernest Romero Climent.

We help companies grow, work better and make smarter digital decisions with websites, custom software, internal tools and AI strategy.

After more than a decade building products and technology in San Francisco, we’ve returned to Catalonia with one clear idea: putting that experience at the service of local businesses.

We work with businesses that want to take a big digital step and want to do it right. We understand their business, identify where technology adds real value and build it with the standard and quality of a world-class team, with the closeness and agility of working directly with us.

That’s Quatre Rius.
