Jean-marc LOUIS -Guillaume DUPONT -Managing Directors

Our vision

A story built on shared values

After many years of experience in respective roles in senior management and then in interim management, we decided to join forces in order to have a greater impact on this historic sector and bring our shared vision to it.

We share the same values and have built LOUIS DUPONT around two pillars : ethics and performance.

An ethical and effective approachto Interim Management

Our Commitments to ethics and performance

Convinced that we can make a difference, we are committed to CSR, inclusion and disability, the employment of older people and gender equality.

Gender equality

Since 2024, LOUIS DUPONT has been actively contributing to the success of the objectives of the RIXAIN LAW passed in December 2021, which aims to accelerate economic and professional equality by requiring balanced representation of women and men among senior executives and members of the governing bodies of large companies, accompanied by a requirement for transparency in this area.

In partnership with EDHEC’s GLOBAL MBA as part of the Sustainable Impact Challenge, we have co-produced a Guide (which has won two awards) to effective and innovative solutions that can be implemented immediately to achieve the objectives of this law. We are also developing a new interim management solution for our clients: the Relais for senior management positions, which allows the position to be reserved until a talented woman from within the organisation who is not yet available can be found.

Employment for seniors

As a member of the SENIORS FORCE PLUS board, a partner of Club Landoy and a supporter of the Senior for Good initiative, we affirm our commitment to seniors. We believe in the wealth of experience they bring.

Every assignment is an opportunity to demonstrate that the skills of senior profiles promote team engagement and the management of complex situations, and that they effectively pass on their expertise. Their commitment and perspective make them key assets in driving organisational change. We believe it is essential to offer them challenges that match their experience and to build bridges to a dynamic and meaningful professional future.

We are committed to supporting the Senior for Good initiative, which promotes the professional integration of seniors.

Inclusion and disability

Work-based support establishments or services (ESAT) enable people with disabilities to engage in professional activity while receiving medical, social and educational support in a protected environment with a view to promoting their personal development. We have chosen to work with AndiKado, the leading online solidarity shop for products manufactured, personalised and/or packaged in ESATs.

This allows us to contribute to the professional integration of workers with disabilities; to raise awareness among our employees and our ecosystem about the fight against discrimination and exclusion; and to participate as a player in the solidarity economy.We are also partners of the ARPEJEH association, which is committed to a policy in favour of people with disabilities, equal opportunities and diversity.

CSR

In 2023, LOUIS DUPONT obtained AFNOR ENGAGÉ RSE certification at the confirmed level, which assesses the degree to which the principles of ISO 26000 is integrated into the organisation’s strategy and management. This international standard aims to provide guidelines for social responsibility, in line with major international founding texts such as the Universal Declaration of Human Rights and the conventions of the International Labour Organisation.

This translates into concrete actions on a daily basis, including: responsible purchasing; appropriate working conditions; and transparency, ethical rules on non-discrimination

All our employees are passionate and driven by the same desire to shake up the interim management sector, supporting companies in their transformation through an ethical and effective approach.
