The Founder's Story
One Question. Two Answers.
How overconfidence, a significant loss, a long period of learning and reinvention led to two ventures I had never planned for.

The Work, and the Irony
For most of my career, I was in the business of making value visible. Thirty-three years across technology enterprises — Wipro, BT, Coforge, Thoughtworks. Different companies, different clients, different decades. But the job was always a version of the same thing: understand what this business genuinely offers, and make that proposition clear enough that the client across the table could see why it was worth choosing.
I was, I think, reasonably good at doing that.
What I couldn't see, for most of those thirty-three years, was the quiet irony running alongside that career. While I was making my employers' value propositions visible to enterprise clients, I was doing the precise opposite with my own financial life. I had a stock portfolio built largely on analyst reports I read regularly but understood only partially. I checked it occasionally — not because I had action to take, but because checking felt like being responsible.
The question I spent three decades answering on behalf of the businesses I worked for — is this proposition clear enough that the client can see it and act on it? — I had never once directed at the businesses I was investing in.
For the better part of two decades, I was a passive investor in the most complete sense. The portfolio was growing, an expert was doing the thinking, and the returns were confirming that the arrangement made sense. I never sat down and asked myself whether I understood the companies I owned. I never tested whether I could explain, in plain language, why a particular stock belonged in my portfolio — or under what circumstances I should exit it.
I didn't know I should have been asking those questions. That's the more honest thing to say.
The Tide
Between 2020 and 2024, my portfolio did something I hadn't quite expected. It kept going up.
In 2023–24, it returned over 60%. For several months, the gains coming in were larger than my monthly salary from a thirty-three year career. When that happened, something shifted quietly in how I thought about myself. A settled confidence took hold. I started feeling less like someone who had gotten fortunate and more like someone who had finally found their thing.
The question I should have been asking — whether this feeling had any basis in reality, or whether I was simply a passenger in a rising market — I wasn't asking. Most people around me weren't asking it either. When things are working for everyone, the idea that circumstances rather than skill might be responsible doesn't surface naturally.
In July 2024, I resigned from my corporate job. I want to say something honest about that decision, because it's easy in hindsight to make it sound either brave or foolish. At that moment, it felt like neither.
It felt like arithmetic.
The portfolio had been doing things that my salary couldn't keep up with. I was spending most of my weekend hours on market research anyway. The question that kept returning was simple: if this is what part-time attention produces, what might full-time focus achieve? What I didn't have — and didn't know I was missing — was any real framework for understanding where we were in the market cycle. Nobody around me pushed back seriously. The numbers were doing the talking, and everyone could hear them.
I walked out feeling like I was finally moving toward something. I was. I just hadn't accounted for what was also moving toward me.
The Floor
September 2024. Three months after leaving. The market had started to fall.
Not dramatically at first. The kind of slide I told myself was temporary — a routine correction in an otherwise intact trend. What I didn't have was any framework for what I was actually looking at. I had data. I had prices. I had a growing sense of discomfort. But discomfort in a portfolio is not the same as understanding what the discomfort means, or what to do about it.
Between October and December 2024, I did something that felt entirely sensible at the time. I kept investing. The market was falling, prices were lower, and I had capital available. The logic seemed straightforward — buy the same businesses at cheaper prices, lower my average cost, position for the recovery that would surely come. I was being disciplined. Thinking long-term. What I was actually doing was adding weight to a portfolio that was sinking.
By January 2025, the Nifty was down nearly 20% from its peak. At the individual stock level, the median fall was 40% or more. I remember sitting with the numbers one evening and forming a figure I had been avoiding. The total loss, on paper, was not something I had allowed myself to calculate clearly before that moment.
What I felt was not panic. Not yet. Something stranger — a kind of suspension. The certainty I had carried into 2024 had not fully converted into doubt. I still told myself the analysis I had done on these businesses was sound. That the recovery would come. What I hadn't yet asked was whether my analysis had ever been any good in the first place.
The panic, when it arrived, didn't announce itself. One morning I looked at the portfolio and something shifted — the hope of recovery stopped feeling like a reasonable expectation and started feeling like a story I was telling myself. I held positions I no longer had a case for, simply because selling felt like admitting something I wasn't ready to admit.
Then I sold. Not everything, but enough. At prices I would not have believed possible six months earlier. The market bottomed in late March 2025. By April, it had begun to recover. I had sold into the floor.
There is a specific kind of education that is only available through loss. It is expensive, and the tuition is non-refundable.
The Reset
Sometime around April 2025, I stopped staring at the portfolio. Not because things had improved — they hadn't, not meaningfully. But because I had reached a point where I understood, with some clarity, that watching prices move was not going to tell me anything I needed to know. I had been reacting to the market for the better part of a year. I had nothing useful to show for it.
What I needed wasn't more data. I needed a framework I'd never built.
So I started reading. Seriously, this time — not the kind of reading where I used to skim for a stock tip or a sector view, but the kind where I sat with an idea until it actually changed something in how I saw things. I read about how the best investors think about risk — not as something to be avoided, but as something to be understood, sized, and managed. I read about market cycles, about the psychology of markets, about the difference between the price of something and the value of it.
It was humbling reading, mostly. Not because the ideas were difficult, but because I kept recognising, on page after page, the exact mistakes I had just made.
Three things became clear in ways they never had been before. Risk is something you size before you invest, not something you manage after prices fall — I had never done that, not once, across twenty years of investing. Markets move in recognisable patterns driven by liquidity, sentiment, and economic conditions that can be studied and understood — I had no idea where I stood in September 2024, and that ignorance was expensive. And the price of something and the value of it are not the same thing; treating them as if they are is the source of most investing mistakes I have ever made or observed.
None of this, I realised, was being taught anywhere I could find online. There were trading strategies everywhere — momentum setups, entry signals, sector rotations. But the foundational thinking — the principles, the frameworks, the mental models that separate a serious investor from someone reacting to prices — was available only in books. That gap stayed with me.
What Emerged
After months of reading, something became difficult to unsee. The investing ecosystem in India — and largely beyond it — is extraordinarily well-stocked with tactical content. Trading setups, IPO analyses, portfolio tips. If you want to know what to buy this week, there is no shortage of opinions.
What is almost entirely absent is the foundational layer underneath all of that. Nobody is systematically teaching how the best investors in history actually think — the principles they built, the frameworks they used to make decisions under uncertainty, the mental models that kept them rational when markets were anything but. I had to find all of that in books, across months of reading, often by accident. And I kept thinking: these ideas should not be this hard to find. They should be organised, accessible, and taught in a way that builds genuine understanding — not just surface familiarity.
That thought became Investor Codex. I started building it the way I would have wanted to find it — not as a course of tips and strategies, but as the foundational thinking that sits beneath every good investment decision. The schools of thought that shaped the best investors. The frameworks they've spent lifetimes refining. Structured in a way that actually changes how you see things, not just what you know.
And then — while I was building that — something else surfaced.
One of the things that changed after the reading phase was how I approached company analysis. It became a daily practice — not scanning for price movements, but genuinely trying to understand businesses. What they do, how they make money, where their competitive advantage sits, what risks they carry.
Somewhere across months of doing this, I noticed a pattern. Before I had opened a single report, before I had looked at a revenue number or a margin or a debt figure, I already had a feeling about certain companies. Not a vague impression — something more specific. A sense of whether this business had built something real in the minds of its customers, or whether it was competing purely on price and hoping for the best.
The brand had spoken before the data had.
And the pattern held. Companies where that early instinct was positive — where the brand had a clarity and a presence that was felt before it was measured — tended to look stronger when the numbers followed.
I had spent thirty-three years doing one thing professionally: making a business's proposition visible to the people it needed to convince. That experience, combined with the analytical lens I had spent the past year developing as an investor, pointed in an obvious direction. That direction became Marque Brand Studio — a brand and positioning practice built on the same principle: that genuine value, made clearly visible, is the foundation of every durable business.
One Question. Two Answers.
Here's what I've come to see, looking back across these two years.
The question at the heart of Investor Codex — what is this business genuinely worth? — and the question at the heart of Marque Brand Studio — is that value visible to the people who matter? — are the same question asked from two directions.
I didn't plan two ventures. I found one question. It just happened to have two answers.
What I have now is not certainty — markets don't offer that, and I've stopped expecting it. But a way of thinking. A set of principles that hold when prices fall and sentiment turns. An understanding of where I am likely to be wrong, and what to do when I am. That foundation took two years and a considerable amount of loss to build. I wouldn't have chosen that path. But I've stopped wishing it had been different.
I'm still building. And for the first time in a long while, that feels like exactly the right place to be.
