Mixvoip and Luxfit - a long-standing success story

For years, Luxfit has relied on Mixvoip – from internet and telephony to IT and networking – benefiting from a partnership that ensures smooth operations and sustainable growth.

A boutique fitness concept built on quality

Founded in 2012, Luxfit has established itself as a premium fitness chain with studios in both Luxembourg and Germany. Their concept focuses on compact facilities, limited memberships, and personalized coaching. With modern equipment and an emphasis on sustainable results, Luxfit offers a high-end, scalable model that is well-suited for franchising.

From first contact to full partnership

The collaboration between Luxfit and Mixvoip began with internet and telephony services at the company’s location in Trier. Over time, this relationship evolved into a comprehensive partnership grounded in mutual trust and efficient communication.

Today, Mixvoip provides many Luxfit sites with internet and telephony. Since 2023, our support has expanded to include IT and network planning, along with SLA-based support services. Most recently, we successfully equipped the Luxfit studio at the Philharmonie in Kirchberg, ensuring a smooth go-live.

Trusted collaboration

Thanks to proactive planning and close coordination, Luxfit benefits from worry-free site launches and smooth IT operations. Luxfit always informs Mixvoip early about new projects, ensuring that phone numbers and network infrastructure are ready on time – and that IT systems, access control, and training equipment are set up before the grand opening.

Current locations

Luxfit currently operates studios in many locations including Junglinster, Esch/Alzette, Trier, and Kirchberg. Expansion continues with upcoming studios planned for Marburg and Luxembourg City, the latter set to open by end of 2025, and Mixvoip will gladly accompany Luxfit on this journey.

What Luxfit says about the partnership

For many years we have been working with Mixvoip in a spirit of trust and we highly value their outstanding support in all matters related to telecommunications and internet. The cooperation is characterized by a solution-oriented approach, quick comprehension, and equally fast implementation of solutions. The reliable and competent support provided by Mixvoip is an essential part of our success.
