The group, which the general public associates with its iconic CK Sportcenter in Kockelscheuer, nevertheless boasts another long-standing pillar: office technology. “The group has repeatedly managed to reinvent itself, expand, launch new ventures or discontinue certain activities, whilst continuing to support its customers,” summarises 
Starting out in photography, CK Group has gradually expanded into printing, office equipment, IT, audiovisual equipment and software solutions. This transformation has taken place not through a sudden shift, but in successive stages, with a focus on complementarity. “We need to be the single point of contact to support businesses in their day-to-day operations,” explains David Gray. “We don’t stop one activity to start another. We need to be able to offer a product, a software solution or a service to support our clients in their business.”
This ability to adapt remains one of the group’s key selling points in a technology market that is seen as increasingly complex for Luxembourg’s SMEs. “Technology is advancing very quickly, and it is not always easy for companies whose core business is not in this field to keep up with these changes,” says the managing director. “Our role is to help and support them through this digital transformation.”
A group that invests in a secure future
The group now boasts over 4,000 clients in its Office Technology division. By 2025, this division is expected to generate around €47m in turnover and employ 170 staff, largely thanks to the acquisitions of iTEC in 2022 and NG Partners in 2025. Seven employees from NG Partners have thus joined the group this year, following the integration of around fifteen employees from iTEC.
The investments we are making today are helping to build a strong group capable of facing the challenges of tomorrow.
This growth momentum is also reflected in the group’s recent developments, notably the opening of the CK Hub in Grass, a new building dedicated to after-sales service. “The company has invested around €8m, with support from SNCI,” explains 
For David Gray, this investment approach is part of the company’s long-standing DNA. “We don’t take a short-term view,” he insists. “The investments we are making today are designed to build a strong group capable of facing the challenges of tomorrow.”
The Sportcenter was a bit of a struggle at first
The group’s second pillar, dedicated to sport and well-being, grew out of Charles Kieffer’s personal passion. A former Luxembourgish tennis champion, he had launched the country’s first indoor tennis courts and fitness centres as early as the 1960s, before developing the Kockelscheuer complex in the 1980s, which has since become a local institution.
“The Sportcenter was a very complicated project at the outset,” recalls Laure Elsen. “People in Luxembourg weren’t yet familiar with this type of large complex combining sport, dining and leisure.” Despite a difficult start and high interest rates, the concept eventually became a fixture on the Luxembourg landscape.
Today, CK Sportcenter employs around 55 people and is expected to report a turnover of around €11m by the end of 2025. The group is continuing to modernise its facilities, notably with a new fitness centre in Howald, whilst increasingly focusing its activities on health, well-being and active ageing.
Older people and AI: the latest developments
“We are moving away from a focus on fitness and weight training towards a more holistic approach to well-being and health,” explains David Gray. The group is now developing programmes specifically for older people and is also incorporating artificial intelligence (AI) technologies into its fitness coaching, without undermining the central role of coaches and the human touch.
Our DNA is the link between performance and people.
“This blend of technology and human connection is precisely what the management team sees as the group’s core identity. Helping our customers work better – more smoothly, more efficiently and more sustainably – whilst feeling good,” sums up the CEO. “Our DNA is the link between performance and people.”
At a time when many companies are talking about AI, digitalisation or changes in the world of work, CK Group remains committed to a philosophy that has remained relatively unchanged for eight decades: investing for the long term, maintaining strong ties to Luxembourg, and continuing to evolve without straying from its family-based values.
