Our story

Impulsa’s journey began with an entrepreneurial vision: to rethink how businesses access financial and strategic expertise. Over the years, the firm has grown steadily, shaped by key milestones that have strengthened both its identity and its expertise.

Founded by Maxime and Grégoire, and later joined by Jean-Baptiste, Romain, and Xavier, Impulsa has evolved into a multidisciplinary firm where accounting, advisory, and business strategy work hand in hand to support leaders with agility and precision.

It all started in December 2012, when Maxime and Grégoire decided to launch their own venture, building an accounting and audit firm from the ground up, driven by ambition and a shared entrepreneurial spirit.

Our very first employee, Romain Cornudet, grew with the firm and became a partner in 2020. A true success story!
We acquire BC Associés, expanding our expertise and crossing the 20-employee mark!

We welcome BC Associés to the group — expanding our capabilities and growing beyond 20 team members!

BC Associés joins the Impulsa family, expanding our reach and taking our team past 20 strong.

The birth of Impulsa. Joined by Jean-Baptiste Barsi, a Paris-based business attorney, to expand our multidisciplinary vision.

We acquire AG Expertise, a Paris-based accounting firm, expanding our presence and capabilities in the capital.

We acquire DEC IDF, a Paris-based accounting firm, expanding our team and reinforcing our expertise in the Paris market.

Impulsa releases its Workplace Equality Index, achieving a score of 82/100 — and setting clear goals for continued progress:

  • Pay equity: 38/40
  • Post-maternity return: 15/15

The year also brings new growth with the acquisition of Cofigef, an accounting firm, and the addition of Xavier Trinidad as partner.
