Proximus invests in Tessares, a new Multipath TCP spin-off of the University of Louvain


Tessares aims to significantly improve convergence between fixed and mobile networks to offer a superior Internet experience.

Proximus and investment fund VIVES II - Louvain Technology Fund are investing in Tessares, a recent spin-off of the Catholic University of Louvain (UCL) which aspires to become the reference supplier of telecom network convergence software.

Tessares and Proximus will be pioneers in developing software solutions based on the "Multipath TCP" standard.  It was within the ICTEAM institute of the UCL that researchers led by Professor Bonaventure, including the founders of Tessares, performed demonstrations of solutions based on this standard allowing telecom operators to combine the speeds of the fixed and mobile networks on their existing network infrastructure. 

The technological collaboration between Proximus and Tessares aims to build on this "Multipath TCP" standard to create a generic solution intended for telecom operators worldwide. This convergence solution has to be tailored to the specificities of each telecom operator such as the performance of their access network, the requirements specific to the applications they use and the needs of their customers. It will enable operators to offer their customers greater bandwidth and increased reliability and security by combining different access networks (fixed broadband, 3G/4G and Wi-Fi).

Between now and end-2016, Tessares will recruit a dozen or so employees with specific skills to develop these new solutions. The profiles it is looking for are computer engineers and/or telecom engineers with a good knowledge of Internet protocols.

Dominique Leroy, Proximus CEO: 

"We're very pleased to collaborate with Tessares to co-develop a new technology that fits perfectly within our strategy of convergence and our objectives of enhanced customer experience. This agreement with Tessares clearly shows Proximus' commitment to innovation and our intention to strengthen the partnerships with the academic world, which is a major driving force of innovation in our country."

Denis Périquet, Tessares CEO:

Having Proximus among the initial investors of Tessares is a very strong and positive signal for our company as our solution will be associated with one of the currently most innovative and exacting telecom operators in Europe.” 

Vincent Blondel, Rector of the Catholic University of Louvain (UCL): 

"This new technology transfer is the result of over six years of research funded by the European Commission and the Walloon Region. It shows once again how important our academic research is to stimulate innovation and the UCL’s significant contribution to regional economic development."

Philippe Durieux, CEO of VIVES II – Louvain Technology Fund: 

"This partnership shows the ability of VIVES II – Louvain Technology Fund to unite a consortium of passionate founders and reference partners in raising funds of a critical size allowing the growth of UCL spin-offs and technological start-ups".
