What we do

Do you speak Martian?

Before we start the project, we'll sit down for coffee to get to know one another.

Definition & Design

We bring our experience in software engineering to guide you through the definition of the project UI and UX.


Built on a Ruby on Rails & Javascript techstack, your projects will be scalable, maintainable and fully tested.


We take care of stages setup and deployments so you don't have to deal with Amazon Web Services, Docker and all that.

Monitoring & Support

We will continuously monitor the project and report to you with only relevant data.

Code Audits

Because of our high expertise in our technologies, we can verify the quality of your team or other provider's code.


Avoid technological locks & long project takeovers by hiring us to train your team and helping you to grow it.

Let us care about what's the best way to be successful in the long run so you can focus on growing your business.

Ready for take-off?

Our clients value long-term relationships, quality over quantity, and want to grow their businesses.

We Are What We Do

We started off as a web-only development shop in 2014. Today, we've grown a multidisciplinary in-house team to offer a wide range of services for medium- & big-sized companies worldwide. Our clients range from the USA to Germany.

We also like to contribute to the local entrepreneurial scene. We're the organisers of Startup Grind Barcelona, the curators of Startup Digest, and we manage an open Slack community for entrepreneurs and startups in Barcelona. You can chat with us there!
