The team
Antoine Thiam
Founder & Finance Advisor | Ex Big4 | +11 years
CFO • IFRS Consolidation • Performance • Governance
Having graduated from Audencia Business School and worked at the Big4 (KPMG, PwC) and international groups, I have accumulated more than 11 years of experience in supporting financial management in the production of social and consolidated financial information, as well as in leading financial transformation projects.
In early 2026, I created NexThiam Advisory with a simple idea:
"To offer leaders an expert capable of bringing clarity when everything is accelerating."
I intervene with precision, autonomy and discretion, to transform sensitive financial situations into reliable decisions.
My role is to be that rare partner who stabilizes, secures and illuminates exactly when you need it most, while relying, when necessary, on a network of trusted partners, selected for their cutting-edge expertise and their commitment to results.
