Thierry is the co-founder and main author of the Monthly Barometer, a succinct predictive analysis exclusively provided to private investors and some of today's most influential opinion and decision-makers. He was until 2011 a senior partner at IJ (Informed Judgement) Partners, an investment boutique for ultra-high-net-worth individuals based in Geneva, and prior to that managing partner at Rainbow Insight, an advisory boutique which he founded, providing tailor-made intelligence to investors. Previously, Thierry founded and headed the Global Risk Network at the World Economic Forum, a network that brings together top opinion and policymakers, CEOs and academics to look at how global issues will affect business and society in the short and long term. For a number of years in succession, Thierry conceived and put in place the programme for Davos and spoke at global, industry and regional events. His other professional experience includes: investment banking (as a Chief Economist and Strategist of a major Russian investment bank and as an Economist at the EBRD in London), think tanks and academia (both in New York and Oxford) and government (with a three-year spell in the Prime Minister's office in Paris).

Thierry has written several business and academic books, and has published four novels (two of which under a pen-name). In addition, he is a public speaker with some of the world’s leading agencies. He also sits on several advisory boards.

He was educated at the Sorbonne and Ecole des Hautes Etudes en Sciences Sociales in Paris and at St. Antony's College, Oxford. He holds two MAs (in Economics and History) and a PhD in Economics.

With his English wife Thierry has four daughters.
