Transaction combines two complementary players, creating a European leader in digital solutions for outpatient care professionals across Belgium and France
Ghent & Paris – Corilus N.V. (“Corilus”) and Sofia Développement (“Sofia”), two leading providers of healthcare software for outpatient professionals, today announced that they have joined forces, creating a leading European platform that will serve over 70,000 practitioners across Belgium and France. The platform is backed by PSG Equity and Rivean Capital (“Rivean”).
Sofia is a leading French provider of practice management software for nurses, physiotherapists, and speech therapists, used by more than 38,000 healthcare professionals. IK Partners (“IK”) acquired a stake in Sofia in March 2022 via the IK Small Cap III (“IK SC III”) Fund, joining existing shareholders, Extens, Capital Croissance and Bpifrance. Corilus, headquartered in Belgium, offers multi-specialty healthcare software that supports, among others, around 40,000 general practitioners, nurses, physiotherapists, dentists, pharmacists, and specialists.
Both Corilus and Sofia have a shared vision to build a transformational European healthcare software provider for outpatient care. Corilus’ experience in scaling healthcare software as a service across multiple professions and strength in patient engagement, combined with Sofia’s deep network across the French outpatient market, will help enable the platform to deliver efficient, innovative solutions for healthcare professionals.
Together, the two companies create a highly complementary platform with significant opportunities to drive growth. The combined group is well positioned to continue expansion across core healthcare professions and accelerate its product roadmap through the integration of new AI-powered tools and telehealth capabilities — including Sofia’s Harry AI assistant and Corilus’ Helena (Pro) solution — as well as accounting and invoicing modules such as Sofia’s ComptaSanté. The partnership also creates a solid foundation for further expansion in outpatient care across Europe.
“We are excited to welcome Sofia into the Corilus group. Together, we have the opportunity to shape the future of outpatient care through technology, combining two innovative teams, two strong markets, and one shared goal to make healthcare more efficient, connected, and patient-focused,” said Franck Frayer, CEO of Corilus.
“Joining forces with Corilus marks an exciting milestone in Sofia’s journey. By combining our deep understanding of the French outpatient market with Corilus’ experience and scale, we are creating a stronger platform that will help simplify the lives of healthcare professionals. We would also like to take this opportunity to thank IK for all their support over the past four years, as well as our historical shareholders Extens, Capital Croissance and Bpifrance which have supported Sofia since 2017” said Geoffroy Lapointe CEO of Sofia.
“We are proud to have supported Sofia’s growth journey and to see the business take this next step alongside Corilus. This partnership creates a solid foundation for continued innovation and expansion, and we are confident that the combined group will play a leading role in shaping the future of digital healthcare in Europe,” said Arnaud Bosc, Partner at IK and Advisor to the IK SC III Fund.
“At PSG Equity, we are committed to backing European software champions that shape the future of their industries. The combination of Corilus and Sofia creates a platform with the scale and innovation needed to accelerate the digital transformation of outpatient care, including through GenAI solutions, and improve outcomes for practitioners and patients alike,” said Dany Rammal, Managing Director and Head of Europe at PSG Equity.
“Rivean Capital is proud to back the combination of Corilus and Sofia. Together, they have the expertise and vision to set a new standard for European healthcare software innovation, and we are excited to support the next phase of their growth journey,” said Nicolas Linkens, Senior Partner at Rivean.
PSG Equity and Rivean will remain the joint majority shareholders of the combined group, continuing to support its next chapter of growth.
