Jeff Bezos

Bezos's investment style is long-term and patient to an extreme degree. He built Amazon by deliberately losing money for years, reinvesting every dollar into infrastructure, logistics, and new businesses.

He told shareholders repeatedly that he would sacrifice short-term profitability for long-term market position. AWS was not a profit center for years — then it became Amazon's most profitable business unit.

Through Bezos Expeditions, he was an early investor in Google (1998, before the IPO), which alone made him hundreds of millions. He also invested early in Airbnb, Uber, and Twitter.

Bill Gates

Gates invests through Cascade Investment LLC in established, cash-generative businesses — railroads, waste management, agricultural equipment, farmland. His biggest single Cascade holding for years was Canadian National Railway.

He has sold most of his Microsoft stock over time. His investment philosophy outside Microsoft mirrors Buffett's: durable businesses with pricing power, bought at reasonable prices.

Jeff Bezos

His core philosophy is customer obsession combined with long-term thinking. He says most companies optimize for the next quarter.

He optimizes for the next decade. He invented the concept of "working backwards" — writing the press release and FAQ for a product before building it, to ensure the team starts from the customer's perspective.

He also invented the "two-pizza rule": if a team needs more than two pizzas to feed, it is too big.

Bill Gates

His core framework: read obsessively, think long-term, and separate emotion from analysis. He takes annual Think Weeks — solo retreats to a lake cottage in the Pacific Northwest where he reads papers and books for two weeks with no interruptions.

He publishes a reading list twice a year at gatesnotes.com. He has said that the best investment he ever made was paying $100,000 to take Warren Buffett to dinner every year.

Jeff Bezos

Bezos told shareholders in 1999 that Amazon would lose money for years. He said the same in 2001.

He meant it. His risk tolerance comes from a framework he calls the "regret minimization framework" — imagining himself at 80 looking back — which weights the risk of not trying far more than the risk of failing.

The risk he manages carefully is existential: through all of Amazon's early loss years, he kept debt manageable and liquidity intact so that survival was never in question. He takes huge bets on the thesis, but he protects the foundation.

Bill Gates

Gates's risk tolerance is intellectual and deliberate rather than impulsive. He takes genuinely large bets — TerraPower on nuclear fission, billions into climate technology, the Gates Foundation's campaigns to eradicate diseases that kill millions — but only after intense research.

His Think Weeks exist to force slow, rigorous thinking on big decisions. At Microsoft, he kept enough cash on hand to run the company for a full year with zero revenue because he never wanted short-term survival pressure to force a bad long-term decision.

That discipline carries into his personal finances.

Jeff Bezos

Bezos lived frugally in the early Amazon years — he famously built his own desk from a door laid on sawhorses to keep costs down. The "door desk" became a symbol at Amazon.

He became extraordinarily wealthy but for years retained a modest personal style. Post-divorce and especially post-CEO, he moved to Miami, bought massive properties, and began a much more public lifestyle with partner Lauren Sanchez.

He exercises in the morning before checking his phone.

Bill Gates

He wakes up early, exercises on a treadmill while watching documentaries, and reportedly does the dishes every night. He has said dishes are meditative.

For a man worth $130 billion, the emphasis on routine is either deeply grounded or very good PR. He drove himself to work at Microsoft for years and lived in a normal house long after he could afford otherwise.

Jeff Bezos

Amazon Web Services. AWS was an internal tool that Amazon began selling to external companies in 2006.

By 2023, AWS generated $91 billion in revenue and accounted for the majority of Amazon's operating profit. It is the dominant cloud computing platform in the world — Microsoft and Google are still playing catch-up.

Bezos had the idea when Amazon was already a massive retailer. He added an entirely different trillion-dollar business on top.

Bill Gates

Microsoft Windows. The decision to license MS-DOS to IBM for the PC while retaining the right to sell it to other manufacturers was arguably the most lucrative business decision in tech history.

Every PC manufacturer then licensed Windows. Gates captured the entire PC market without building the hardware.

By 1999, Microsoft's market cap hit $616 billion.

Jeff Bezos

The Washington Post acquisition is the most common answer. He paid $250 million for it in 2013 and has poured money into it since.

The Post has struggled commercially and faces the same headwinds as all legacy print media. Separately, his rocket company Blue Origin has consistently lagged SpaceX in capability and ambition — Blue Origin's New Shepard is basically a tourist ride compared to SpaceX's reusable orbital rockets.

Bill Gates

Missing the internet. Microsoft was late and initially dismissive of the internet as a platform.

Gates eventually course-corrected and wrote the Internet Tidal Wave memo in 1995, redirecting the entire company toward internet strategy. But the delay allowed Netscape to establish footholds, and Microsoft's browser monopoly tactics led to the landmark antitrust case United States v.

Microsoft in 2000, which threatened to break up the company.

Jeff Bezos

Jeff Bezos graduated from Princeton in 1986, worked at several finance firms, and became the youngest-ever senior vice president at D.E. Shaw hedge fund by age 30.

In 1994, he quit to drive cross-country with his then-wife MacKenzie, writing the Amazon business plan in the passenger seat. He started selling books from his Bellevue garage, moved operations to Seattle, and launched Amazon.com in 1995.

What followed is one of the greatest compounding business stories in history: books to everything, retail to cloud computing (AWS), a logistics network that rivals national postal services. Amazon's revenue in 2023 was $574 billion.

Bezos stepped down as CEO in 2021 to focus on Blue Origin, his space company. He also owns The Washington Post (acquired 2013 for $250 million).

Bill Gates

Bill Gates was born in Seattle in 1955. He taught himself to program on a PDP-10 at age 13.

He enrolled at Harvard in 1973, dropped out in 1975, and moved to Albuquerque with Paul Allen to found Microsoft. Their break came when they licensed an operating system to IBM for the original PC — and crucially, retained the rights to sell it to anyone else.

That decision made Microsoft. Windows became the standard operating system for the world.

Gates became the world's richest person in 1995 and held that title for much of the next 15 years. He transitioned out of Microsoft's day-to-day around 2000 and fully moved into philanthropy via the Gates Foundation.
