Who we are

Oïkologos is a public relations and communications consultancy that helps firms to develop and market thought leadership contents.

In the knowledge economy, the most respected brands raise their leadership through the depth and breadth of conversations they generate. To nurture those conversations, firms need to produce innovative ideas, disseminate data and insights, and contribute to public debates, just as actively as they promote products and services. Sharing cognitive content has become key to strengthen their relationships with internal and external stakeholders.

To corporations and executives willing to grow their clout and connections, Oïkologos offers its strategic advice as well as operational support.
