About Gregory

Grégory Dahan is an expert in project management and process transformation, with over 15 years of international experience in various sectors such as banking, energy, healthcare, chemistry, and food. He stands out for his mastery of change management and digital transformation strategies, particularly through agile methodologies like Scrum and PMI. Grégory has led numerous complex projects, notably in companies like ING, Medtronic, Dow, and Vidya, where he has optimized processes, improved productivity, and managed IT transformations.

As CEO of Vidya since 2014, he founded and led a startup specializing in the sustainable food industry, where he managed the company's financial, logistical, and commercial aspects, while developing an innovative communication strategy. He also has strong experience in human resources management and international logistics flows, overseeing the import of products from Asia to Europe.

His ability to unite teams and drive change is recognized in every mission, as demonstrated by his work at eFarmz where he successfully restored motivation and cohesion to teams after a poorly accepted digitalization. Grégory is also proficient with data management and ERP tools such as SAP and Odoo, and distinguishes himself with his skills in data modeling and business infrastructure.
