Meet our team

In 4soft, I don’t really feel that I’m working. It’s due to the great atmosphere and friendly work culture, but also the potential of the projects we develop. I really appreciate that we spend a lot of time together, not only at the office.

For the first time in my working experience, I feel like the company gives me absolute confidence and takes my opinions into account in the decision-making process. It’s not a facade – 4soft really pays attention to the inclusivity and advocates for flat organization structure instead of hierarchy.
