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. To
support its growth, Down2Earth Capital II (D2E) acquires a stake in the group.


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.


In the coming years, Sisu wants to continue to focus on organic growth, leveraging its presence in
growing markets, the structural trend towards more flexibility and its specialized project consultants,
which provide a strong position in the “war for talent”. At the same time, targeted acquisitions should
result in geographical growth and additional niches.


The entry of D2E coincides with the decision of co-shareholder Gaël Terroir to phase out his
operational role. CEO Stéphane Collignon and the other members of the key management team will
remain on board to realize the ambitious plans.
“Industry expertise and long-term customer relationships have been the cornerstones of our group for
many years,” says Stéphane. “However, the development of a group also creates the need for more
structure, to which we have already taken important steps in recent months. In D2E we have found the
ideal partner to further support this professionalization.”, he adds.


“The Sisu Group has built up a strong position in attractive areas of expertise,” says Alain Keppens of
Down2Earth. “As a result, we see an important role for the group in the consolidation of the sector,
which we are happy to support.”
