Examples of key projects include acquiring business in a foreign country, merging two entities, improving operations, accelerating change and transitions, closing a production site, unexpectedly replacing a top manager with a key function in the organization, managing human or economic crises, developping the top line, securing financing for strategic projects.

Sadis & Co supports companies and organizations active not only in the private sector (industry or services), but also in the public and non-profit sectors.

More recently, Sadis & Co has decided to develop a specific approach to SMEs and in particular to Family Owned businesses because they represent the economic growth and employment opportunities of tomorrow.

For each assignment, Sadis & Co sets up a project team with three key stakeholders: the client representative, the interim manager / project leader, and Sadis & Co representative or counsellor who will govern the entire assignment. This team is collectively responsible to reach the assignment’s objectives defined at the start by Sadis & Co in agreement with the client.

Through our vast experience acquired through hundreds of assignments of all kinds, Sadis & Co has refined its approach and focuses on the following success factors:

  • the provision of strategic and operational advices throughout every assignment and in particular in defining the objectives of the assignment at the start,
  • the quality of its candidates and its selection and matching process,
  • the speed of action,
  • a thorough follow-up of the project, the client and the managers throughout the assignment,
  • a full independence

The track record of our associated consultants, experts and interim managers allows us to offer sector- and function-specific competences



We work closely with  YOU (our client’s leaders) to create the necessary level of confidence and trust.
We conceive the changes to be brought about and we conduct their implementation under our control.


For Sadis & Co, every client is unique.  This is why we apply our methodologies proven  and refined through hundreds of experiences in transition and change management to come to a taylor made approach for every client. Experience is an important factor of success. Our people have experienced success. Together, we know what works and what does not.
Our mission is to provide fully implemented management solutions to allow our clients to succeed and prosper.

Our service goes from concept to implementation ;
Our people are hands onOur commitment is on results

To provide a bespoke approach, we team up with the leaders and executives at the client.
Listening, understanding the clients specifics, being open and creative allow us to define realistic but creative solutions to be implemented.

We are not paid to be nice but to do the job. Every job is unique.
