Marwan Mery is an expert in negotiation, lie detection, and profiling. He was born on 29 September 1975 in Beirut. He has authored several books and gives conferences on these subjects.

His remarkable career started with his international business studies at Sorbonne University in Paris. To fund his studies, Marwan came up with the idea of playing poker. It soon became a passion for him. He became fascinated about bluffing. Afterwards, the various positions he held in multinationals all involved negotiation. Air France, Danone, and Red Bull are amongst the large groups he has worked with.

Marwan has also helped casinos in France and elsewhere to identify scams and cheaters, for over 10 years. With his experience in the field, and as a profiling expert, he authored many books on human behaviour and lie detection.

In the 2010s, Marwan Mery took the entrepreneurship plunge. He set up the company Egocia, and then created MMG (Marwan Mery Group). In 2012, Marwan Mery and Laurent Combalbert partnered to found ADN Group, the « Agence des Négociateurs ». Together, they intervene in crisis situations in multinationals and governmental organisations all over the world.

Their life as professional negotiators is so fascinating that it inspired the TV series Ransom, broadcast on TF1 since 21 June 2017.
