After three decades within major international firms, Nadine Tinen chose to build a close-knit group of partners from the Big 4, firmly rooted in African realities. At the head of VINKA, a pan-African firm reshaping the consulting market in French-speaking Africa, the former CEO and Territory Senior Partner of PwC Sub-Saharan Francophone Africa (2017-2025) made the choice to structure an agile organization, designed to handle complex issues involving audit, taxation, governance, transformation, and execution. An overview of a collective that now forms the foundation of expertise and the backbone on which the “VINKA model” rests.

Trained in computer science at Concordia University in Montreal, Armand Nganou has worked in environments combining digital transformation and operational management, notably at MTN Cameroon and within the PwC Sub-Saharan Francophone Africa network. At the head of VINKA Services, he oversees operational support activities.
Present in Cameroon and Benin, with upcoming establishments planned in Ivory Coast, Senegal, and the DRC, VINKA has structured itself as a regional platform combining expertise from major international firms and a deep understanding of local realities, according to a source close to the firm. Launched in 2025, the structure is part of a sector reshaping context, as former PwC partners in Francophone Africa, after their split from the global network, have focused on ensuring the continuity of ongoing mandates.
This dynamic comes as PwC officially announced the withdrawal of its Sub-Saharan Francophone Africa network in 2025, covering about ten countries, followed a few months later by EY. In an African consulting market estimated at over $2 billion and growing annually by 5% to 7%, this reshaping favors the emergence of independent pan-African players, positioned between international standards and local constraints.
