Our culture

We breathe technology

Everything we do is focused on technology. Whether we use Django, Python or React The choice for these languages is based on a need for structure and whether we can work with it as a team as a whole.

Project team

We put together a project team for each project. The synergy between different people and their skills is our strength.

The team is our number one

We work with people, for people. A customer is part of our team and that is how we act internally. Building a long-term relationship with each other and customers together is a continuous process.

Work hard, play hard

We approach many things from this motto. Because we work hard and celebrate our successes. At Four Digits we love to cake, drinks and parties!

We like to go out. Just get out of the office. The noses in the wind. On a company visit to the Efteling, we step into our favorite attraction. We also like to do rounds of karting. We attend conferences, code sprints and actively participate in communities. For example, Wagtail. We have organized Wagtail Space a number of times.
