Client Testimonials.

I have had the pleasure of working with Paul-Jean Aubertin over the past few years in managing the accounting and financial aspects of my various startups. What really stands out about Paul-Jean is his ability to combine accounting rigor with a business vision. Even in highly technical fields like tech and SaaS, he has always provided a strategic perspective, anticipating financial needs and optimizing accounting operations. His deep understanding of the startup ecosystem, especially internationally, has been a true asset in growing our activities. Thanks to his support, we have been able to manage periods of rapid growth efficiently, structure our financial operations optimally, raise funds from Business Angels and VCs, and fully focus on our growth drivers. Paul-Jean is not just an accountant; he’s a strategic partner you can truly rely on.

Quentin Lechemia, Founder and CEO of Caption & Checkfluence

I have been working with Paul-Jean and Hexagone Advisory for several years. They manage the review of our French entities’ accounts and provide regular support with my accounting and tax questions. Responsive and proactive, they perfectly assist me in my interactions with the group to which we belong. Their international experience is a real plus for our subsidiary entities of a large American group (knowledge of US GAAP and transfer pricing).

Franck Lacroix, Finance and Administration Director France, Purolite

We recently launched a French subsidiary to develop sales of our products in the French market. We have been working with Hexagone Advisory since the start of this project. Being from Ireland, we had very little knowledge of the French administrative environment. But we were perfectly guided by Paul-Jean and his team on the legal, financial, and tax structuring of the project, as well as on all the day-to-day administrative issues we faced, like opening a French bank account.

French Subsidiaries of Foreign Companies.

Hexagone Advisory has extensive expertise in international accounting and taxation, enabling us to support French subsidiaries of foreign companies with efficiency and precision. We understand the specific challenges these companies face, and we are committed to providing high-quality service tailored to their needs.

Our strengths for foreign subsidiaries:

  • International expertise: With our knowledge of accounting and tax issues specific to international businesses, we ensure compliance with both local and international regulations.
  • Fluency in English: Smooth communication with international teams is essential. We are fluent in English, which facilitates exchanges with headquarters, shared service centers, and foreign partners.
  • Efficiency within tight deadlines: We are accustomed to working in environments with short deadlines (fast closing, reporting), allowing us to deliver on time without compromising quality.
  • Adaptability to multinational organizations: With experience in large corporate environments, we know how to navigate complex structures with numerous stakeholders and strict processes (shared service centers, SOx, consolidation, etc.). Our flexibility enables us to adapt to the expectations and procedures of the group.

We understand the importance of integrating subsidiaries into the group’s strategy, and we ensure strict compliance while optimizing accounting and financial performance.
