David Ohayon is a digital transformation executive and independent consultant with 27 years of experience spanning strategy, technology, and operations.
He has held C-suite roles (CDO, CTO, Chief Transformation Officer) in PE-backed companies across retail marketing, energy efficiency, luxury concierge, and online travel, including Altavia Group, Effy Group, John Paul/Accor, and Weekendesk. Earlier in his career, he worked at BCG on consumer goods transformations for Reckitt Benckiser, Natixis and Sanofi.
His practice focuses on three intersecting areas: digital and AI transformation (strategy through deployment), data architecture and governance, and operating model redesign. He takes a business-first approach to AI, anchoring every engagement in measurable P&L impact rather than technology adoption for its own sake.
David holds an engineering degree from CentraleSupélec and an Executive MBA from INSEAD and operates in interim, fractional, and advisory modes, primarily across France and Western Europe.
