Sisu

Sisu is a group that includes companies such as Strand Associates Consulting, Catalay, Prosource and
Nedworks and specializes in staffing, consultancy and training of specialized project consultants in
pharma, engineering, project management, Digital Marketing, HR, Finance and supply chain.
The foundations of the current Sisu Group were laid in 2009 with the establishment of multi-specialist
Strand Associates Consulting by Stéphane Collignon. After a rapid growth trajectory, the first step in
expanding the group was taken in 2018 with the acquisition of Nedworks (digital marketing), followed
by acquisitions in engineering (Catalay) and project management (Prosource and ProjectPolis).
Meanwhile, activities in HR, finance and supply chain consulting were launched internally. Today, the
group employs more than 280 project consultants and 50 internal employees.
