Montefiore Investment and Activa have entered into exclusive negotiations to jointly lead the next phase of Arche MC2’s growth

By 27 January 2026No Comments

Activa and Montefiore Investment announce that they have entered into exclusive negotiations with a view to completing a transaction involving the capital of Arche MC2, the leading software publisher for the medico‑social sector in France. Upon completion of the contemplated transaction, Montefiore will become a majority co-shareholder of Arche MC2 alongside Activa, which will reinvest on an equal basis. The remainder of the share capital will be held by the company’s management team, which will reinvest significantly alongside the financial shareholders.

Based in Aix-en-Provence, Arche MC2 develops software solutions for stakeholders in social services, personal care services and the medico-social sector, covering the entire value chain, from local authorities and public institutions to healthcare and home care providers, as well as operators of care facilities.

Arche MC2 has experienced strong growth since Activa became a shareholder six years ago. At that time, the group generated approximately €10 million in revenue, compared with nearly €70 million today, notably driven by several structuring external growth transactions. Operating in a rapidly expanding and still highly fragmented sector, the group, which employs 550 people, plays a major role in accelerating the digital transformation of operators and therefore benefits from sustained organic growth across all its sub-segments.

This co-investment project between Montefiore and Activa aims to support Arche MC2 in a new phase of development, notably through the rollout of new software solutions, the acceleration of the group’s commercial momentum, and the continuation of an active buy-and-build strategy.

“We are delighted to support Arche MC2 in this new phase of development alongside Activa. We have been particularly impressed by the quality of the management team and the company’s strategic positioning at the heart of a critical and dynamic sector. Together, we are keen to support Arche MC2 in this next stage of growth, leveraging our recognized expertise in accelerating growth projects and our strong experience in the healthcare and technology sectors.”

Alexandre Bonnécuelle and Eric Schaefer, Partners at Montefiore Investment.

“We have been supporting Arche MC2 since 2019 and are particularly proud of the journey achieved alongside Guillaume Bouillot, Jean-Michel Monin and their teams since our investment. In just a few years, and with the support of Turenne Santé and Groupe Up, the group has multiplied its revenues by seven, driven by an ambitious and focused buy-and-build strategy as well as the continuous development of best-in-class solutions, establishing itself as the French leader in software publishing for the medico-social sector. Today, we are very pleased to welcome Montefiore Investment alongside us to support the group’s next phase of growth, in France and internationally, in line with the strategic roadmap pursued with the management teams.”

Christophe Parier and Alexandre Masson, Managing Partners at ACTIVA.

“Together with Activa, we are delighted to welcome Montefiore Investment to support this new phase of growth. The quality of its teams in France and across Europe, its recognized expertise in software, and its entrepreneurial DNA make Montefiore Investment a partner of choice to support both our organic and external growth. This partnership allows us to maintain a France-based shareholder structure, fostering the development of sovereign software solutions serving the medico-social ecosystem, including organizations and local authorities, healthcare professionals, patients and their families, while also representing a key asset in supporting the Group’s future international development projects.”

Guillaume Bouillot and Jean-Michel Monin, Chairman and CEO of Arche MC2.
