About us
A small consultancy that performs like a large team.
What we are
SANFELIU is Joan Sanfeliu Vilarrasa’s custom software consultancy on AWS, based in Barcelona: business apps, ERP and CRM integrations, automation and websites, with AI where it saves hours.
We work for companies that already have systems and a team that uses them every day, and that know which process eats up their hours.
We do it with a senior engineer in charge of every project, collaborators when the project calls for it and AI inside the process. It always starts the same way: a fit call.
Who is behind it

Where to check
When a project calls for it, we bring in collaborators for design, content or development, always under the same technical lead.
Why you can trust us
We spend half our time building our own products (taula.ai and Guestproof): software in production on AWS that we pay for and that, when it breaks, we fix ourselves. The other half, inside SMEs that already have their software in place and need someone who really understands it.
We build with AWS and with AI inside the process: it’s what lets us show you a working demo in days, not weeks.
