Sam Altman

Altman is a prolific early-stage investor who backs deep tech and moonshot ideas. His portfolio through YC and personal investments includes hundreds of companies.

His personal bets tend toward civilizational-scale technology — nuclear fusion, longevity research, AI safety. He has said he thinks the most important investments of the next decade will be in energy and AI.

He has repeatedly said he holds no equity in OpenAI itself, which is unusual for a founder running a company of that size and something he has been asked about constantly.

Scott Galloway

Galloway's personal investing style is relatively conservative given how loud he is. He keeps a heavy allocation in index funds and real estate.

He does make concentrated bets on individual stocks when he has conviction — he famously held Amazon for years. He angel invests occasionally but is not prolific.

His real wealth comes from business exits and media income, not portfolio management.

Sam Altman

Altman believes we are approaching AGI — artificial general intelligence — and that it will be the most transformative and potentially dangerous technology humans have ever built. He thinks the right response is to build it carefully rather than cede the frontier to those who might not.

He argues that the returns from AI will be so large they will need to be distributed broadly to prevent catastrophic inequality. He has floated ideas around universal basic income funded by AI productivity.

Scott Galloway

Diversify, own assets, and do not confuse being smart with being lucky. Galloway preaches that the most reliable path to wealth is boring — buy index funds, own property in growing cities, and let time do the work.

He is deeply skeptical of anyone who claims they can consistently beat the market.

Sam Altman

Altman has said that playing it safe at this moment in history is the most dangerous thing he could do. His belief: AGI is coming whether OpenAI builds it or not — the only question is who builds it and with what values.

That conviction makes conventional risk aversion feel irresponsible to him. He holds large personal positions in nuclear fusion companies and longevity biotech — bets that could return 1000x or go to zero.

He has said that any genuinely interesting bet carries existential downside risk. That is what makes it interesting, not a reason to avoid it.

Scott Galloway

Moderate. Galloway has experienced the full spectrum — he had a company go public and then go bankrupt (Red Envelope), which taught him that financial ruin is always closer than you think.

Post-L2 sale, he became much more conservative. Heavy real estate holdings in New York and Florida.

He preaches diversification publicly and mostly follows his own advice, with occasional concentrated stock positions.

Sam Altman

He has written about sleeping 8 hours, exercise, not scheduling meetings before 11am, eating the same lunch every day, and blocking large chunks of uninterrupted time for thinking. He is a known prepper — he has said he owns land, gold, guns, and antibiotics in case civilization collapses, which is a mildly alarming admission from the CEO of the company building AGI.

Scott Galloway

Galloway owns significant real estate in New York and Florida. He talks openly about his wealth and spending — nice apartments, good restaurants, private school for his kids.

He is not frugal and does not pretend to be. But he is very intentional about where money goes.

He has said his biggest financial luxury is "buying back his time" — paying for convenience so he can focus on what matters.

OpenAI and ChatGPT. The launch of ChatGPT in November 2022 was the most consequential product launch in tech in at least a decade.

It brought AI from a niche technical field into mainstream awareness overnight and made OpenAI the fastest-growing AI company in history. Altman navigated the transition from nonprofit to commercial entity, secured $13 billion from Microsoft, and built a company valued at $157 billion within five years.

Scott Galloway

Selling L2 to Gartner for an estimated $134 million in 2017. He built L2 into the go-to benchmarking firm for digital competence of luxury and consumer brands.

The exit, combined with his media career taking off simultaneously, catapulted him from "NYU professor" to "famous rich guy who yells about tech on the internet."

Sam Altman

Being fired by his own board in November 2023 — and the board's subsequent reversal. Whatever actually happened in those five days is still murky.

What is clear is that the board lost control of the situation the moment it became obvious that without Altman, most of the company would leave. The board members who voted to fire him are gone.

Altman is back with more power. The episode revealed real governance problems at one of the most consequential companies in history.

Scott Galloway

Red Envelope. Full stop.

Galloway has been brutally honest about this — he took a gift e-commerce company public, it was valued at hundreds of millions, and then it went bankrupt. He has called it the most painful experience of his career and has said it took years to emotionally recover.

He lost a significant amount of personal wealth in the collapse.

Sam Altman

Sam Altman dropped out of Stanford in 2005 to co-found Loopt, a location-sharing startup. Loopt was acquired in 2012 for $43 million — not a huge exit but enough to establish him as a serious founder.

He then became president of Y Combinator in 2014, succeeding Paul Graham. Under Altman, YC expanded from a small cohort model to a much larger operation with global reach, including backing Airbnb, Dropbox, Stripe, and hundreds of others in its portfolio.

In 2019, he stepped down from YC to become CEO of OpenAI. The company launched ChatGPT in November 2022, which became the fastest-growing consumer application in history — 100 million users in two months.

In November 2023, the board fired him. The entire company revolted.

Microsoft — OpenAI's biggest investor — nearly hired him to run a new AI division. Five days later, he was reinstated with a restructured board.

OpenAI's valuation hit $157 billion in 2024 and roughly $852 billion by 2026.

Scott Galloway

Scott Galloway is a serial entrepreneur and NYU Stern School of Business professor who became famous for his brutally honest takes on Big Tech. He founded nine companies over his career, including L2 (a business intelligence firm sold to Gartner in 2017), Red Envelope (an e-commerce company that went public then bankrupt), and Prophet (a brand strategy firm).

His 2017 book The Four, about Amazon, Apple, Facebook, and Google, became a bestseller. His YouTube channel and Prof G podcast reach millions.

He called Amazon buying Whole Foods before it happened. He also co-hosts Pivot with Kara Swisher, one of the most popular tech podcasts in the world.

He teaches brand strategy at NYU and is known for his profanity-laced, data-heavy lectures that go viral every semester.
