Florence HUGON

CFO & Head of

Florence leads our Finance, Sales administration, and Procurement teams.

As CFO, she oversees the business performance and strategic financial planning, M&A as well as the liaison and reporting with the different NTT entities. Florence joined Transatel in 2009 as a financial controller and assisted in the company’s continuous growth over the years. This position made her a key player in the NTT acquisition of Transatel, especially during the due-diligence phase.

In addition to her role at Transatel, Florence coaches entrepreneurs in the early stages of their startups.

Florence graduated from Skema Business School with a Corporate Finance major.



After several experiences in Consulting, Sandra joined Transatel in 2010. In a context of strong growth and competition, she has contributed to the development of the company from start-up to SME, then to an integrated subsidiary of an international company (NTT) with a turnover of 100 billion euros. Her Human Resources contribution was also key in the due diligence conducted by NTT at the time of the acquisition of Transatel.

The transition from 50 to 250 employees required in-depth work both on recruiting employees with rare and sought-after skills, as well as on developing their skills and adapting them to an increasingly international context. On the strength of having helped Transatel build a multicultural team, one of the main challenges has been to continuously maintain the corporate culture around innovation, agility and entrepreneurship. The industrialization and digitization of the HR function are now at the heart of the strategy, in addition to supporting the managerial line in meeting the challenges of the years to come.

Sandra is daily inspired by this quote from Antoine de Saint-Exupéry: “The most beautiful job is above all uniting men.“
