Ajay Banga showed me that starting over is not a setback. It is the strategy.

I am not someone who talks about himself easily. I want to put that on the table before anything else, because this series asks exactly that of me, and I think the discomfort is worth naming rather than glossing over. Most of my working life has been spent on the operational side of things, quietly in the background, focused on the work, letting the results do whatever talking needed doing.

But I have come to understand that staying invisible is not the same as being modest. There is a point where the silence stops protecting you and starts obscuring you. The people who should understand what you are building, and why, and who has been shaping your thinking along the way, they cannot form that picture if you never give them the material to work with.

So this series exists. And in this edition, I want to talk about Ajay Banga.

I want to be clear about something before I go any further: I have never met him. I am not in his network. I have not had a conversation with him, in person or otherwise. Everything I know about Ajay Banga comes from his public speeches, published interviews, documented career decisions, and the record he has built across four decades. That is the only honest basis on which I can write about him. And I think that honesty matters, because it is precisely the point. The people who shape how you think are not always the people in the room. Sometimes they are the ones whose work you study from a distance, whose decisions you examine long after they were made, and whose ideas arrive in your life at exactly the moment you are ready to use them.

Most people in Australian business circles know his name in outline form. They know the Mastercard number. They know the World Bank title. What tends to get far less attention is the specific texture of how he has operated across a career, and why, when I first started paying close attention to his public record, I kept finding myself thinking: this is the map for something I am already in the middle of navigating.

From a Punjabi Sikh military family to the World Bank, across four industries and four decades.

Ajay Banga was born in Pune in 1959, the son of Lieutenant General Harbhajan Singh Banga. Growing up inside a military family meant constant relocations: a new school, a new city, a new set of social rules to learn, over and over. That kind of childhood is its own curriculum. You learn early that your environment will change whether you want it to or not, and that the skill worth building is not mastery of any single context, but the capacity to find your footing in a new one with some speed and composure. Most people spend their careers optimising for stability. Banga spent his accumulating range.

He completed his economics degree at St. Stephen's College in Delhi, then his postgraduate diploma at IIM Ahmedabad in 1981. Then he went to work. Not in banking, and not in technology. He went to Nestlé, where he stayed for thirteen years. What followed was four industries, four entirely different operational environments, and the same throughline running through all of it: he walked into each new context, listened carefully, and then moved with decisive urgency once he understood what the situation actually required.

Execution is the plan. Everything else is preparation.

The thing that struck me first about Banga was not the track record. Track records are easy to admire from a distance. They are also quite hard to learn anything useful from, because by the time you are reading about someone else's results, you are not inside the decisions that produced them. What struck me was his attitude toward uncertainty, specifically, his refusal to let the absence of a complete roadmap serve as a reason not to move.

If you don't try new things, if you don't take chances, you will achieve very little reward. The plan is not the point. Execution is the point.

I have sat with this idea for a long time, because it runs directly against the training that produced me. I come from aeronautical and mechanical engineering. That is a discipline built on the premise that you get it right before you ship it. Tolerances are precise. Failure modes are exhaustively documented. The system is verified before it goes anywhere near a live environment. That rigour is not optional. It is the entire point. And across critical network infrastructure management at scale, it served me well.

But there is something that kind of training instils that is harder to see: a deep suspicion of moving before you are ready. A tendency to treat incompleteness as a reason to wait. In critical infrastructure, that instinct keeps people safe. In building a technology company from scratch, it is the thing most likely to keep you exactly where you are.

Banga understood that waiting for the perfect plan is, in practice, a decision not to move. And in competitive environments, not moving is itself a strategic choice, the decision to give ground to whoever is willing to act before certainty arrives. The people who build things that matter are rarely the ones who had the most complete plan. They are the ones who were willing to start while the plan was still forming, and to let the work itself supply the missing information.

That required deliberate unlearning on my part. Engineering teaches you to get it right before you ship it. Rebuilding a career in technology, really rebuilding it, not just applying an old title to a new context, teaches you that shipping is how you discover what right actually means.

Coming from outside is not a liability. It is a form of competitive intelligence.

Banga entered Mastercard in 2009 as a genuine outsider to the payments industry. He had spent his career in consumer goods, restaurant chain expansion, and international banking. He did not carry the mental grooves of someone who had spent twenty years inside a card network. And I think that absence was not incidental to what he achieved. It was central to it.

By his own public account, he spent his early months at Mastercard observing, not performing, not announcing strategy, not restructuring for the sake of demonstrating authority. He was watching customers, reading competitors, and listening to the internal culture before making any significant decisions. When he did move, the insight was sharper for it. He had seen something that deep insiders frequently cannot see, because their familiarity with the problem is also their blind spot.

I grew up playing chess competitively. Chess teaches you something specific about this kind of patience that most other pursuits do not: the difference between reacting to what is on the board right now and reading what the board is becoming. The strongest players are rarely the fastest responders. They are the ones who have already thought three moves ahead while their opponent is still processing the last one. Banga's early months at Mastercard read, to me, like a grandmaster entering an unfamiliar opening. He did not rush to assert the position. He developed his pieces quietly, built a true picture of the terrain, and moved with decisive force once he understood what the position actually required. I recognise that approach. It is not caution. It is precision.

Our competition isn't Visa. It's cash.

This is not a clever line. It is a precise redefinition of the problem. If your real competition is cash, something embedded in billions of daily transactions, trusted because it is tangible, frictionless, and requires no infrastructure to use, then you are not in a fight with another card network. You are in a fight against a behaviour. That is a much larger, more consequential, and ultimately more commercially significant problem to be working on. The frame determines the scale of what you build.

I have thought about this reframe in the context of my own transition. When I left critical infrastructure management, most of the advice I received was framed around the obvious comparisons, what companies were doing what I had done, which titles transferred most cleanly, where the safest landing was. But that is the Visa frame. It is asking which competitor you most closely resemble. It is not asking what behaviour you are actually up against, or what a genuinely better alternative would look like.

The harder question, and the more useful one, was what the real incumbent was. In my case, it was not any particular company or role. It was a version of myself that had optimised so deeply for one context that the accumulated expertise had started to look like the ceiling rather than the floor. The outsider's edge is only an edge if you are willing to use it. It does not activate automatically. You have to choose to see your own experience as raw material for something new, rather than as a credential that should translate directly.

Decency is not a soft skill. It is a structural advantage.

One of the most underappreciated things Banga has put into words publicly is what he calls the Decency Quotient, or DQ. The concept reads simply, but it is deceptive. You can have a high IQ, a refined emotional intelligence, and a track record that impresses every room you walk into. But if you treat the people around you as instruments rather than as individuals with their own agency and stakes in the outcome, you are systematically leaving performance on the table. You are building an organisation that operates at the level it is required to, rather than the level it is capable of.

DQ is about having your hand at their back, not on their face. You get more out of people when they feel supported than when they feel managed.

I have been on both sides of this. I have worked inside environments where the leadership model was sustained performance pressure with very little psychological safety. And I have watched genuinely capable people quietly withdraw. Not in any dramatic way, the best people rarely make a scene. They just gradually stop bringing their full thinking to the conversation. They do what is asked of them and nothing beyond. The discretionary effort disappears. The initiative disappears. The willingness to flag a problem before it becomes a crisis disappears. The organisation becomes exactly as capable as it must be, rather than as capable as it could be.

The distinction he draws publicly is precise. High standards and genuine accountability are not in conflict with decency, they require it. The point is not to lower the bar. The point is to recognise that you get more from people when they feel the organisation is working with them, not on them. Setting the standard and then walking away from the people trying to meet it is not management. It is the abdication of the most important part of the job.

Culture, as Banga has said consistently in public forums, is built through hard work, honest knowledge-sharing, and the cross-fertilisation of ideas across disciplines. It is not manufactured through values statements pinned to a wall or team-building exercises scheduled on a Friday afternoon. It accumulates through how leadership behaves on an ordinary Thursday, in the small, largely unobserved moments that people remember long after the formal announcements have been forgotten. That rings true to everything I have seen across two very different careers.

The risk most people fail to calculate is the risk of not trying.

In interviews, Banga speaks about risk without the mythology that usually surrounds it in founder circles. He does not romanticise the leap or dress it in retrospective inevitability. He approaches it practically. If you do not try, you do not learn. If you do not learn, you do not compound, your understanding, your relationships, your capability. And if you do not compound, you cannot build anything that genuinely lasts or that genuinely matters.

There is a version of safety that presents itself as stability but is functionally stagnation. You stay in the role that is familiar because the unfamiliar alternative carries the possibility of failure. You optimise relentlessly for the local maximum instead of accepting short-term exposure in pursuit of something more significant. Banga's career is a four-decade argument against that kind of risk management. Not the argument of someone who was never afraid. The argument of someone who understood that the real risk was the one on the other side of the ledger, the cost of not trying, which is almost always harder to see.

I had my own version of this reckoning. Before I committed fully to the transition, before I stepped out of critical infrastructure and into the early, uncertain, very exposed work of helping build a technology company from the ground up, I wrote a resignation letter that I never sent. Not because I was paralysed by indecision. I wrote it because the act of writing it produced a clarity that deliberation alone could not provide. It forced me to construct the full argument to myself: what, precisely, am I remaining for? What am I prepared to give up in order to pursue the alternative? The letter sat for a while. When I eventually made the move, I already knew why. The clarity came through the preparation, not through the moment of decision itself.

The solo motorcycle ride through the Himalayas, up to Umling La pass at 19,024 feet, among the highest motorable roads on earth, was part of the same process. Not adventure for its own sake. A deliberate creation of space. At that altitude and in that remoteness, the competing considerations that fill an ordinary working week fall quiet. What remains is what actually matters. For me, what remained was a very clear view of where I was heading, and an equally clear view of what it was going to cost to get there. That ride did not make the decision for me. It confirmed the one I had already made.

Prepare philosophically, then act decisively. The pondering is not the plan. It is the prerequisite for the plan being worth anything.

Irreplaceable by accumulation. Not by announcement.

Looking back at Banga's arc, the pattern that runs through it is not cleverness, though he is clearly that. It is not ambition, though that is present too. The pattern is accumulation, of operational depth, of cross-industry perspective, of relationships built through genuine engagement rather than transactional networking, of credibility earned through problems actually solved rather than merely discussed.

The best careers, like the best companies, are not planned into existence. They are built through execution, through patient observation, and through the discipline to keep moving when the plan runs out. Banga's life is evidence that the right preparation is not a detailed roadmap. It is the accumulation of depth, technical, cultural, relational, that gives you options other people simply cannot access, because they have not done the work of acquiring them.

This series is a deliberate choice to let the philosophy speak out loud, because the people who should understand what is being built here, and who is building it, and what has shaped the thinking underneath, deserve more than a headline. They deserve to see the workings.

The reinvention from critical infrastructure to technology leadership is not finished. It is underway. We are in the middle of proving it, not the end of it. And some of the clarity that makes that work feel worth the risk owes a genuine debt to the man who tripled a company's revenue, brought half a billion people into the financial system, and then quietly decided the work still was not done.
