ACTIVA ACQUIRES A STAKE IN IMPULSA GROUP
Jul 21, 2026
Activa announces an investment in the Impulsa Group, a leading player in accounting expertise and business consulting. As part of this minority LBO transaction, Activa will become a key shareholder alongside the founders, Grégoire Proust and Maxime de Vieth, and the management team.
Founded in 2012 in Paris by Grégoire Proust and Maxime de Vieth, Impulsa supports its clients across the full range of their accounting, financial, legal, human resources and payroll requirements, as well as digital transformation initiatives. The Group serves diversified client base of approximately 3,000 companies and has developed particularly strong expertise in the technology, retail and e-commerce, and international business sectors. Impulsa currently generates revenue of €20 million. Backed by a team of approximately 160 employees between Paris and Lille, Impulsa stands out for the quality of its client support, its entrepreneurial culture, and a high level of process digitalization, notably with a robust technology platform and proprietary performance management tools.
With Activa’s support, the Group intends to further accelerate both its organic growth and its external growth strategy, building on the successful completion of several acquisitions since its inception. In particular, Impulsa aims to strengthen its regional footprint, broaden its range of complementary services and consolidate its position as a leading platform in the highly fragmented French accounting services market.
Activa, specialist in supporting SMEs in B2B services through primary transactions, will contribute its expertise in structuring Impulsa's growth pathway, both in terms of organic growth and buy-and-build opportunities, as well as the integration and digitalization of its operations.
Grégoire Proust and Maxime de Vieth, founding partners of the Impulsa Group, state : “We are convinced that Activa is the right partner to support us through this new stage of our development. We share the same entrepreneurial culture, a strong commitment to service quality and the ambition to build a leading player capable of supporting its clients over the long term while continuing to drive market consolidation.”
Alexandre Masson and Christophe Parier, Managing Partners at Activa, add : “We are proud to support Grégoire, Maxime and their teams as they continue to pursue their growth ambitions. Impulsa has all the attributes we look for: a premium positioning, a loyal client base, a digitalized business model and an outstanding management team. The Group is ideally positioned to play a key role in the transformation and consolidation of the French accounting services market.”
