David Bellairian's Business Book Recommendations: 5 Books Every Founder Should Read

I'm David Bellairian, founder and CEO of Glencore Associates and founder of AIDiscover. I read constantly, mostly on planes and mostly business and investing books, and I get asked often enough for recommendations that I figured I'd write down the five I actually reread and hand to other people. These aren't the trendiest titles out right now. They're the ones that have held up.

1. The Outsiders, by William Thorndike

Thorndike profiles eight CEOs who quietly outperformed the market by a wide margin over long careers, almost none of them household names. What ties them together isn't charisma or product genius. It's capital allocation: knowing when to reinvest in the business, when to buy back stock, when to acquire, and when to simply do nothing and let cash accumulate. Most of these CEOs ran lean corporate offices and spent an unusual amount of time on the handful of decisions that actually moved the numbers.

This is the book I'd hand to anyone managing a portfolio rather than a single business. Running five asset classes at Glencore means most of my job is capital allocation in exactly this sense, deciding where a dollar works hardest right now, not defending a favorite position out of habit.

2. Zero to One, by Peter Thiel

Thiel's central argument is that real progress means going from zero to one, building something genuinely new, rather than one to n, copying something that already works. He's skeptical of competition itself, arguing that it erodes the margins a business needs to actually do interesting long-term work, and that the businesses worth building are the ones that can temporarily escape competition entirely by being different enough that comparison doesn't apply.

It's a useful, slightly uncomfortable book to read as someone who runs a marketing agency. AIDiscover works because it doesn't try to out-compete larger agencies at their own game. It's built around a different way of doing the work.

3. Principles, by Ray Dalio

Dalio built Bridgewater around two ideas that sound simple and are extremely hard to practice: radical truth and radical transparency. Decisions get made by weighing the merits of an argument, not the seniority of the person making it, and mistakes get logged and studied rather than buried. The investing sections are useful, but the operating philosophy is the part I go back to most, especially the discipline of writing principles down before you need them, rather than improvising under pressure.

I've written here before about how Dalio's debt-cycle research shapes how I read the broader economy. This book is where that research sits inside a much larger, and honestly more personal, framework for decision-making.

4. The Lean Startup, by Eric Ries

Ries's build-measure-learn loop is now common enough language that it's easy to forget how useful the underlying idea is: treat a new product or campaign as an experiment with a hypothesis, not a finished bet you're defending. Ship the smallest version that can actually teach you something, measure the real response, and let the data change your mind before you've sunk real money into being wrong.

This is close to how AIDiscover approaches campaign work for clients. A lot of marketing advice assumes you already know what will work. This book is a better fit for the more honest position, which is that you don't, and the fastest path to finding out is a small test, not a big meeting.

5. Thinking, Fast and Slow, by Daniel Kahneman

Kahneman spent a career studying the specific ways human judgment goes wrong, and the book's split between fast, intuitive System 1 thinking and slow, deliberate System 2 thinking has become the standard vocabulary for talking about decision-making under uncertainty. The chapters on overconfidence and loss aversion are the ones I think about most as an investor, since both biases push toward exactly the mistakes that are easiest to make with real money on the line.

It's a long book and a dense one, and it rewards reading slowly. I'd rather recommend fewer pages read carefully than a stack of business books skimmed for quotes.

Why these five

None of these are recent releases, and that's on purpose. A business book that's still worth reading fifteen or twenty years after it was written has survived contact with a lot of real decisions, which is a better filter than a bestseller list. I'm David Bellairian, founder and CEO of Glencore Associates, a Los Angeles private investment and asset management firm, and founder of AIDiscover, an AI-powered marketing and brand discovery agency. I write about investing, AI implementation, and company building on Substack and Medium.
