Orthalis acquires Dentalsoft with the support of Extens
Lyon (France), February 27, 2026
With the support of Extens, Orthalis strengthens its position as a leading software provider for orthodontists and contributes to market consolidation through the acquisition of the Dentalsoft group.
Extens, a leading European investor in healthcare software, is supporting Orthalis’ development and financing the acquisition of the Dentalsoft group, giving rise to SignalSoft Développement, a new leading platform dedicated to software solutions for orthodontic professionals.
This strategic transaction significantly strengthens Orthalis’ leadership position in its market while actively contributing to the consolidation of a still fragmented sector. By combining complementary expertise, strong customer bases and well-established solutions, SignalSoft Développement gains the resources required to accelerate its development.
An ambitious industrial project focused on product value and European expansion
The merger between Orthalis and Dentalsoft opens a new phase of growth for the newly formed group. SignalSoft Développement intends to invest significantly in enhancing and expanding the functional depth of its software solutions to better meet orthodontists’ operational needs and the increasing demands of their practice.
The combination of teams and expertise will accelerate the development of high value-added features, improve user experience and strengthen the robustness of the platforms offered. In addition, this transaction provides the group with the scale required to expand into new European markets and pursue targeted external growth opportunities.
This transaction follows years of development led by Gérard Guillerm and his son Arnaud, who successfully built and expanded Orthalis around a clear industry vision and a strong commitment to product quality. Their dedication — combining sector expertise, close relationships with practitioners and strong innovation capabilities — has enabled Orthalis to establish itself as a reference player in its market and to create the conditions for this new phase of development.
Strengthened governance to lead the integration
The integration process and execution of the strategic roadmap will be led by Laurent Urien, CEO of SignalSoft Développement, who will oversee team integration and the implementation of the group’s development ambitions.
