Gretta Antonescu

Gretta Antonescu is a board-level voice at the intersection of finance, technology, and governance, recognised for turning complexity into clarity when the stakes are high. A certified Non-Executive Director, Board Advisor, and neuroscience-trained Executive Mentor, she operates where digital disruption, regulatory expectation, and human performance converge. Her mandate is simple: help boards “see around corners,” steady executive decision-making under pressure, and build systems that scale across markets.

Her multi-industry career spans financial services, technology, and entrepreneurship, giving her a panoramic understanding of how strategy, risk, and culture interconnect.
Gretta’s leadership was forged within the global financial system, including senior executive roles at Credit Suisse, where she led large-scale digital-transformation and governance initiatives across trading, operations, and technology. Earlier, as a young entrepreneur, she co-founded a fast-growing enterprise that earned the World Economic Forum’s Fastest-Growing SME Award in Eastern Europe, a milestone that marked the beginning of her international trajectory.

Today, her expertise encompasses Digital Strategy, Technology and Operational Risk Governance, Cybersecurity & AI Risk Management.

With Eastern European roots, professional chapters across Anglo-Saxon and Southern European markets, and strong ties to the Swiss business community, Gretta brings cultural dexterity and geopolitical insight to global boardrooms.

As a Mentor at Harvard Alumni Entrepreneur in Residence, she extends that same analytical rigour to mentoring, equipping senior leaders to elevate executive presence, sustain performance, and amplify impact in complex environments.

She believes modern oversight must evolve from reactive assurance to proactive stewardship, particularly in an era defined by AI, cybersecurity, and data-driven decisions—a philosophy that guides her board and advisory work today.
