OUR TEAM

thomas efstathiu, founding partner

During his 10 years’ experience, Thomas has tackled multiple challenges in very different contexts - in France, Greece, Switzerland and the United States - on issues of strategy and management, at every key step of the value chain. Driven by his interest in the complexities of the financial sector, Thomas has been focusing on the resilience of financial institutions and their impact on the real economy.

VIALYBER is the result of a factual observation : the disillusionment of consultants frustrated by their profession is the direct consequence of the loss of the consulting model’s relevance as well as the lack of foresight regarding its upcoming challenges.

Thomas believes that the step towards independence that he has applied to himself is the key to a new generation of consultants, and a new concept of consulting, creating a true virtuous circle for clients.
