The partner
Didier Ngatchou Nana
Managing Partner · Chartered accountant & statutory auditor
He founded Mettallion Consulting in Nanterre in 2015 with one conviction: companies growing between Africa, Europe and North America deserve a firm that knows each of those shores as well as they do.
Ten years on, he leads a team of chartered accountants, auditors, lawyers and tax specialists across four offices. He stays in direct contact with company leaders and their boards, and drives the firm's work on green finance and non-financial reporting.
