About
Accelerating the digital transformation of organizations by combining agility, societal impact, and human collaboration.
Since 2017, 5th Floor has been developing tailor-made solutions, designed with and for their users.


Our story
In 2017, the founders, joined by a dozen or so consultants, created 5th floor. The common vision is clear: tailor-made development must rhyme with agility, efficiency and must be societal.
Today, Vincent Warnimont, Luc Vansteenkiste, Gilles Stragier and Evert Penninckx are at the head of a structure that has 130 employees, divided equally between employees and freelancers, mainly developers and analysts.
Specialising in supporting companies and public institutions in their digital transformation, 5th floor relies on solid expertise in the public sector to develop solutions with a societal impact.
The company is distinguished by a strong commitment to people: a collaborative approach, transparent communication, agile delivery of features, all in the search for a balance between performance and the well-being of our employees.
We value long-term partnerships, based on trust and a long-term vision.
This approach has earned 5th floor the title of “ambassador” for medium-sized companies in the province of Liège at the Trends Gazelles 2024. An award that highlights healthy, innovative and responsible growth.
Our approach
Our teams have a wide range of expertise (tailor-made development, product ownership, scrum, UI/UX, data, AI) and work in an agile way to support you in your digital transformation.

Our experience in complex environments, such as the public sector, allows us to be aligned with you. We develop applications and software by integrating end users at every stage, whether they are employees, customers or citizens.
As your partner, we support you and your IT teams in your digital transformation. We want to support you in the change, while respecting your DNA.

Constant innovation with agility
As the world evolves, so does our CSR approach.
Our teams are constantly looking for new methods, technologies and ideas to amplify our positive impact. The agile approach is not just a technical term at 5th floor. We use it as part of our CSR approach, allowing us to innovate, adjust and constantly improve our impact.
Our partners
an extension of our mission
For us, choosing a client or a project is not only based on commercial criteria but also on the values conveyed.
Each project reflects our CSR commitment. Our community is made up of companies that, like us, aspire to a more sustainable and ethical future.
Social responsibility in our DNA
We consider that our core value, the human being, goes beyond purely professional and internal aspects by committing ourselves to contributing to the well-being of society as a whole.
CSR guides our strategy. It’s much more than a label, it’s our DNA, a conviction, a conscious choice.


At the heart of communities
We don’t just implement strong CSR internally. 5th Floor is actively engaged in the communities where we operate, supporting local initiatives and social projects.
For us, sustainable change is also collaborative change, it is deeply rooted in our values. And it is by supporting local initiatives and working with our partners that we can make a difference.
