CEO CLUBS GREECE FORUM
Building Your Transformation Journey with Confidence
Creating value in a fast-pacing world.

LOCATION
Athens Conservatoire
FORUM VISION
Transformation is no longer a project. It is the job.
Every organisation represented at this Forum is already changing. The defining question is whether that change is building value or simply using up energy.
The forces reshaping markets no longer arrive one at a time. Geopolitics, the cost of capital, artificial intelligence, shifting customer expectations and the scarcity of talent now move together, and they compound.
Strategies that were once set for five years are revisited every quarter. In this environment, confidence does not come from certainty. It comes from clarity of direction, discipline in execution, and the judgement to know which bets truly matter.
Most organisations still run transformation as an initiative with a start and an end. The leaders who will create value in the years ahead treat it as a permanent capability. They connect the moving parts of the business rather than managing them in isolation.
This Forum brings together CEO Clubs Greece and the insight of EY and EY-Parthenon to take that challenge on directly: how to transform with confidence, and how to turn change into lasting value.

FREQUENTLY ASKED QUESTIONS
Everything you need to know
Who should attend this Forum?
This Forum is for CEOs and senior executives who are leading change and want to be sure it creates value. Attendance is open to members of CEO Clubs Greece and their executive teams, members of Your Directors Club (YDC), and selected non-member CEOs by invitation.
Is this Forum relevant if my company is not running a transformation program?
Yes. The Forum is not about running a formal transformation program. It is about leading a business that has to keep adapting: to new technology, changing customer expectations, a tighter talent market, and the cost of capital. If any of these affect your company, the discussion applies to you, whether or not you call it a transformation. The practical question for the day is whether the changes you are making are creating value.
Is this a Forum about AI?
AI is part of the conversation, but not all of it. Two sessions look at it directly: how it is changing customer growth, and where advantage comes from when every competitor can access the same AI. The Forum places it alongside the other forces reshaping markets, because they no longer arrive one at a time. The argument we make is that value is created where strategy, customers, people, and capital are aligned.
What can I expect to take away from the day?
You can expect a clearer view of where change is creating value in your organization and where it is costing more than it returns, along with ideas you can put to work straight away. The Forum brings together the insight of EY and EY-Parthenon with something harder to find elsewhere: the collective experience of the CEO Clubs Greece community, and of members who are facing these same decisions in their own companies. Hearing how peers have handled them is a large part of the value.
What sets Forums apart from other CEO Clubs Greece events and initiatives?
Forums are the flagship thought leadership gatherings of CEO Clubs Greece. They are larger in scale than the club’s regular events and bring the wider community together around a single strategic theme, explored through expert keynotes and panel discussions. This Forum, curated by EY Greece, combines the experience of the CEO Clubs Greece community with outside expertise to look at how to turn change into lasting value.
How do I register, and can I bring colleagues?
