John Psaila, CEO and Managing Partner at Deloitte Luxembourg
How would you describe Deloitte Luxembourg today, and the scope of your own activities and responsibilities within it?
Deloitte Luxembourg today is one of the country’s leading professional services firms and one of the most international platforms in our wider network. Over the decades, it has grown from a modest accountancy practice into a firm of real breadth, bringing together Audit and Assurance, Tax, Advisory and Consulting, supported by the many capabilities required to serve clients whose needs no longer fit neatly into one discipline, one market, or one line of service.
In many ways, that evolution mirrors Luxembourg’s own. As the country became more international, more complex, and more strategically relevant, so too did the expectations placed on firms such as ours. Our role is to help clients navigate complexity with seriousness, whether the issue is assurance, regulation, transformation, transactions, tax, technology, or governance. Increasingly, what matters is not only technical knowledge, but the ability to connect disciplines, jurisdictions, and perspectives in a way that is genuinely useful.
That is one of the defining features of Deloitte Luxembourg. We are a Luxembourg firm, certainly, but much of what we do is international by nature. Our people come from a great many backgrounds, our clients operate across borders, and the questions we are asked to help solve rarely stop at the edge of one jurisdiction. That gives the firm a particular texture: local in its roots, international in its reality.
As for my own role, I have had the privilege of leading the firm as Managing Partner and CEO over the past eight years. That has meant responsibility not only for performance, but for far more enduring matters: culture, quality, strategy, succession, governance, reputation, and the long-term strength of the institution. One learns quickly in such a role that leadership is not the management of a year. It is the stewardship of a trajectory.
What I have therefore tried to do, throughout, is to help build a firm that is not merely successful, but substantial. A firm that clients trust, that talented people wish to join, and that can remain relevant in a world where complexity has become the default condition.
If I had to describe Deloitte Luxembourg in a single phrase, I would call it a Luxembourg firm of international consequence: ambitious, multidisciplinary, deeply rooted here, but fully engaged with the wider world.
Please introduce yourself to our readers so they know your personal story.
I joined Deloitte in Malta in 1995. At the time, I could not have imagined the shape my professional life would eventually take, nor that the firm I had joined as a young auditor would one day become the one I would be entrusted to lead in Luxembourg.
I first came to Luxembourg in 1999 through a short exchange. I then returned to Malta and spent two formative audit seasons in Budapest. In 2001, I came back to Luxembourg, and that return proved decisive. What had begun as an international opportunity gradually became home.
I was appointed Partner in 2008 and spent many years serving large international clients, particularly in the audits of listed groups. That work formed me in a lasting way. It taught me to value precision over posture, substance over ornament, and calm judgment over noise. In 2015, I joined our Executive Committee, and, in 2017, I was elected Managing Partner of Deloitte Luxembourg at the age of 39. I was honored to be reappointed for a second and final term in 2021.
Professionally, I am a Fellow of the Association of Chartered Certified Accountants, a member of the Institut des Réviseurs d’Entreprises and of the Ordre des Experts Comptables in Luxembourg, and an authorized statutory auditor.
But if one steps back from the formal titles, my story is, in truth, rather simple. It is the story of someone shaped by several countries, by one firm, and by having found in Luxembourg both a home and a calling.
What are the values that underpin your leadership and guide your decisions?
I have always believed that leadership begins with clarity. One must know what one is trying to build, what one is trying to protect, and what one is not prepared to trade away for the sake of short-term convenience.
Trust sits at the center of professional life. It does not come with title or rank. It is earned slowly, tested repeatedly, and can be lost far more quickly than it is built. It depends on judgment, consistency, honesty, and the willingness to face reality even when reality is inconvenient. I have always tried to decide based on what is true, what is fair, and what serves the institution best over time.
I also believe deeply in stewardship. No serious institution belongs to any one individual; however visible their role may be for a few years. One inherits something, one strengthens it if one can, and one leaves it better ordered for those who follow. That should instill both ambition and modesty.
Finally, I believe strongly in the collective. I have never had much patience for leadership as personal theater. In a partnership, the moment people stop asking what serves the firm and begin asking only what serves themselves, decline has already begun.
When you select employees, what are the three most important things you look for?
The first is seriousness of mind. I do not mean heaviness of manner. I mean people who think properly, who are curious, who are prepared to deal with complexity, and who do not use confidence as a substitute for thought.
The second is attitude. Over a long career, attitude often proves more decisive than early sparkle. I value discipline, resilience, teachability, and the desire to improve. Those qualities compound.
The third is character. We work in an environment where technical strength is essential, but it is never sufficient on its own. Respect for others, generosity in teamwork, and the ability to contribute to a collective effort matter enormously. In the end, one is not only hiring for capability. One is also hiring for the kind of institutional citizen a person is likely to become.
What advice do you give to young people starting their careers?
Learn your craft properly. That may sound obvious, but it is less common than it should be. There is a great deal of impatience in modern professional life, and far too much appetite for visibility before substance. Yet credibility is still built the old way: through preparation, reliability, consistency, and work that stands up when examined closely.
I would also say this: do not be in too much of a hurry to be seen. Be in a hurry to become good. Titles arrive when they arrive. What matters is whether, by the time responsibility comes, you have built the judgment to carry it.
And finally, say yes to opportunities that stretch you. Much of my own career was shaped by experiences that took me out of the familiar, across borders, across cultures, and into situations for which I did not yet feel entirely ready. That is often where growth begins.
How important is lifelong learning, and what are your recommendations for professional development?
It is indispensable, because experience on its own does not keep a person fresh. Left unattended, it can just as easily become habit.
The world changes quickly, but more importantly, it changes unevenly. Markets shift, technologies alter expectations, regulation evolves, and the assumptions one relied on five years ago can become poor guides to the present. So professional development has to be more than technical updating, necessary though that is. It must also involve broadening one’s judgment, deepening one’s understanding of the world, and preserving the ability to learn without defensiveness.
At Deloitte, we have invested significantly in learning over many years, including through our Deloitte Universities, because we take development seriously. But the real point is not the infrastructure. It is the disposition. The best professionals I have known were rarely the ones most eager to advertise their expertise. They were often the ones most aware of how much there still was to understand.
My recommendation is therefore straightforward: remain teachable. The strongest professionals are rarely those who assume they have finished becoming. They are the ones who continue to learn, to adapt, and to deepen, and who therefore remain valuable in a world that does not stand still.
What is your assessment of the current attractiveness of Luxembourg as an international business location?
Luxembourg remains one of the most attractive business locations in Europe because it has learned, over time, how to inspire confidence. That matters more than ever in a period marked by geopolitical strain, economic fragmentation, and sharper competition for capital, talent, and relevance. It still offers something many larger jurisdictions struggle to provide consistently: political stability, legal certainty, international openness, and an institutional seriousness that reassures investors and businesses alike.
Its financial center remains the clearest expression of that strength. Luxembourg continues to play a role in European and global finance far greater than its geography would suggest, particularly in investment funds and in cross border activity more broadly. But the country’s attractiveness does not rest on finance alone. It also lies in multilingual talent, administrative efficiency, institutional credibility, and a business culture that understands international complexity without making a performance of it.
That said, attractiveness cannot be treated as a permanent asset. Luxembourg faces real pressures. Housing affordability has become a serious constraint, skills shortages remain visible in key sectors such as technology, finance, and construction, and the wider cost base is under closer scrutiny in a more competitive environment. These challenges do not cancel out the country’s strengths, but they do mean that success cannot be taken for granted.
My view, therefore, is that Luxembourg remains highly attractive, but must continue to earn that position. Its advantage has never come from size. It has come from foresight, adaptability, and credibility. In a more brittle world, confidence has become a scarce asset. Luxembourg still has it, but it must continue to deserve it.
What would you like the Luxembourg government to do to enhance its attractiveness?
Luxembourg should continue doing what has often served it best: anticipating change rather than waiting to be overtaken by it. Its success has never rested on size alone. It has rested on seriousness, adaptability, and the ability to remain open while preserving confidence. In a more demanding international environment, that balance becomes even more important.
Housing, in my view, now sits near the center of the question. A country that wishes to remain attractive to talent cannot allow access to housing to become a structural weakness. Affordability is no longer simply a social issue. It has become an economic one, and increasingly a strategic one.
At the same time, Luxembourg must continue investing seriously in skills. The country has benefited enormously from being international, educated, and outward looking, but skills shortages are now visible in important parts of the economy. Competitiveness in the years ahead will depend not only on openness to talent, but on the ability to develop, attract, and retain the capabilities that a more technological and specialized economy will require.
More broadly, I would hope Luxembourg remains faithful to what has long distinguished it: a regulatory and institutional environment that is credible, efficient, and proportionate. Businesses can adapt to many things, but they value coherence, predictability, and seriousness. Those qualities matter greatly, and they should never be taken lightly.
So my view is not that Luxembourg needs to reinvent itself. It needs to remain recognizably Luxembourg while being faster where speed matters, bolder where pressure is rising, and careful never to erode the credibility that has made it attractive in the first place.
Please share with our readers your risk and benefits analysis of AI’s impact on business and government activities over the next five years.
Artificial intelligence is having, and will have, a profound effect on both business and government over the next five years. It will improve speed, increase analytical capacity, reshape service delivery, and change the economics of many tasks that, until recently, depended almost entirely on human effort. Used well, it can remove friction, sharpen insight, and allow people to focus on areas where judgment, creativity, and responsibility matter most.
But technology does not absolve us of responsibility. On the contrary, it tests the quality of the judgment around it. The risks are real: bias embedded at scale, weaker accountability, false confidence in automated outputs, and a gradual erosion of discernment if convenience becomes the highest value.
My concern is not that machines will become human. It is that humans, under enough pressure and seduced by enough efficiency, may begin to imitate machines in the way they think, decide, and relate. That would be a far more serious loss.
So the central question is not whether AI will advance. It will. The question is whether our institutions will remain wise enough, and our leaders human enough, to govern that advance properly. The race is not simply to be first. It is to ensure that, when all this moves from novelty to normality, we have not surrendered the very qualities that made human judgment worth trusting in the first place.
Outside of business activities, what are the priorities of your life both today and in the future?
I see this period less as an ending than as a change of rhythm. After eight years in this role, I remain deeply committed to our firm and fully intend to stay active within it, contributing in ways that are useful, constructive, and aligned with the next phase of its leadership. Roles evolve, as they should, but loyalty and attachment do not simply disappear with a title.
At the same time, I would like to create more space for what deserves it. Professional life can be immensely rich, but also exacting, and there comes a point at which one values a little more balance, a little more perspective, and a little more time deliberately given.
I would also like to return, more consciously, to interests that the pace of recent years has too often kept at a distance. There are books I have not yet read and mean to. There is a world I would like to observe more attentively through photography, with its discipline of looking properly before deciding what is worth keeping. And there is writing, which has long mattered to me, not only as expression, but as a way of thinking more clearly.
Beyond all that, I do feel a responsibility to give something back. Life has been generous to me in many respects, and I would like, in whatever way proves most useful, to continue contributing to our firm, to Luxembourg, and to the wider community around me.
So, my priorities, if put simply, are to remain useful, to live with greater measure, to think more deeply, to see more clearly, and to give back with gratitude and purpose.
