Tech billionaires who founded multiple companies

While running a single tech company is a difficult task, running several is nearly impossible. Yet Elon Musk, Jeff Bezos, and Larry Page have proven that with the right vision, strategy, and risk tolerance, it’s possible to redefine industries across the board.

These tech billionaires don’t just build companies; they build ecosystems that reshape how we live, work, communicate, and even explore space.

These men aren't just wealthy; they're technological pioneers shaping the future through their empires.

1. Elon Musk 

Elon Musk, the richest man on Earth, is also arguably the most high-profile tech entrepreneur of the modern era.

As of 2025, Musk owns and operates multiple companies, each playing a crucial role in different sectors, from electric vehicles (EVs) to brain-computer interfaces and artificial intelligence (AI).

Tesla

Musk became a key figure at Tesla in 2004, leading the push to revolutionise the automobile industry. 

Under his leadership, Tesla grew from a struggling EV startup into a global giant, producing electric vehicles, battery technology, solar energy systems, and even robotic humanoids.

SpaceX

As founder and CEO of SpaceX, Musk has redefined space travel. The aerospace company successfully developed the Falcon and Starship rockets, works closely with NASA, and aims to colonise Mars. 

Moreover, SpaceX’s reusable rocket technology has slashed launch costs and opened new frontiers in commercial space exploration.

xAI

Founded in 2023, Musk’s AI venture, xAI, focuses on creating AI tools that prioritise human alignment and scientific advancement.

In March 2025, xAI merged with X (formerly Twitter) to form XAI Holdings, with Musk owning about 33%.

Neuralink

Neuralink is Musk’s notable venture into neurotechnology. The company aims to create brain-computer interfaces that can help people with paralysis, restore vision, and ultimately merge human cognition with AI.

The Boring Company

First started as a joke, The Boring Company is now developing underground transportation tunnels to fight urban congestion. 

Notable projects like the Vegas Loop are already operational, and more cities are in the pipeline.

2. Jeff Bezos

The tech billionaire Jeff Bezos, founder of Amazon, transformed the way people shop and consume content.

However, his influence extends far beyond e-commerce. After stepping down as Amazon’s CEO, Bezos shifted his focus toward space exploration and media.

Amazon

From a modest online bookstore in 1994, Bezos turned Amazon into a global retail empire. The company now operates in cloud computing (i.e., AWS), entertainment (i.e., Prime Video), and more.

Blue Origin

Bezos’s ambitions extend beyond Earth. In 2000, he founded Blue Origin, a private aerospace company with a bold vision: to preserve Earth by moving heavy industry off-planet.

Later, in 2021, he flew to the edge of space aboard the New Shepard rocket, marking a milestone in commercial space travel.

The Washington Post

In 2013, Bezos acquired The Washington Post for $250 million. Since then, the newspaper has experienced a digital renaissance and become a profitable, influential media outlet under his ownership, posting profits in 2016, 2017, and 2018.

3. Larry Page

Larry Page, co-founder of Google, has consistently been one of the most visionary minds in the tech industry. With Sergey Brin, he created the most powerful search engine in history, but he didn’t stop there.

Google

Founded in 1998, Google is the world's dominant Internet search engine. It also excels in digital advertising, cloud services, and mobile software i.e., Android.

Page was instrumental in many of its most ambitious expansions, including Google Maps, Gmail, and YouTube’s growth.

Alphabet Inc.

In 2015, Page and Brin restructured Google into a holding company called Alphabet, allowing each division to innovate independently. Google became just one of many Alphabet subsidiaries.

However, Page later stepped down from the CEO role but remains involved with Alphabet’s more experimental ventures, focusing on projects that aim to change humanity's future.
