Custom software & app development in Barcelona We design it. We build it. We run it.

We are a Barcelona studio, founded in 2002, that designs, builds and runs custom software and apps: web platforms, iOS and Android apps, AI integration and learning platforms (LMS). The proof is our own products —REPLAI, OhMyWay, Parlumi, Momeka and the ACME apps—: we design them, we build them and we run them.

How we workFrom first sketch to production server, with nobody in between.

Design

We start with the people using it

We come from product design: every technical decision starts from the experience of the person using the screen.

Ownership

We build it and we run it

Design, development, infrastructure on AWS and Azure, and support. Our products are ours end to end.

AI

AI across the whole process

We work AI-first, from prototype to deployment, and bring AI into the product when it solves something real.

Languages

Multilingual from day one

Spanish, Catalan, English, French, Italian and Portuguese. And GDPR-compliant privacy by default.
