28. Dell Technologies

Dell, which has been rooted in Austin since Michael Dell started the company as a University of Texas-Austin student in 1984, made the top 30. The computer manufacturer moved up six slots this year, is listed on the Global 500, and is one of the 100 most profitable corporations in the Fortune 500.

Dell is the second-largest non-oil company in Texas and the sixth biggest company in the state by revenue. As a global power, it is the largest shipper of PC computers in the world.

To cope with the pandemic, Dell decided to double down on work rather than hit the pause button. Dell gained 8,000 more employees in 2020 and employed a record of 165,000 worldwide as it shifted to push 90% of its employees into remote work. The company's emphasis on digitization and mobile technology for consumers during the pandemic paid off—the company had record revenue in 2020.

Dell, with multiple local offices, currently employs around 13,000 people in Central Texas and plans on keeping most of its employees in a remote or hybrid work format.

80. Oracle

Oracle, a global corporation that sells database, software and cloud technologies, was one of the major tech companies to announce its relocation of its headquarter to Austin from Southern California in 2020, after establishing a half a million-square-foot facility on East Riverside in 2018.

The corporation rose up two spots to No. 80 on the Fortune 500 in 2021 and is one of the 100 most profitable on the list. Oracle also cracks the Global 500 and is one of 71 Fortune 500 companies to have a female CEO, Safra A. Katz.

During the pandemic, Oracle faced big changes. Aside from moving its headquarters across states, the company began using artificial intelligence, augmented reality and voice commands (instead of "Hey, Siri", think "Hey, Oracle") to help companies move into the cloud.

According to Shailesh Singla, Country Head & Senior Director, Employee Experience/HCM Business at Oracle, the pandemic actually sped up digital technology, especially using AI as a human resources function, by many years.

100. Tesla

While electric car giant Tesla hasn't moved its headquarters to Austin (although teased last year), its CEO Elon Musk, has already made the move. The man who called Austin a "boomtown" has plans to manufacture the company's Cybertruck and Model Y products out of the Giga Texas plant, set to be completed later this year in southeast Travis County.

The electric vehicle company just reaches the top 100 in the Fortune 500 list, rising 24 slots in the rankings. The company has seen job growth as Tesla works to employ nearly 10,000 Austin-area residents at the new Texas plant.

Musk famously had run-ins with COVID policies in California, where he was originally located, spurring him to join the California migration in the summer of 2020. Tesla famously struggled in its first decade of existence, but the EV entity grew more than a cult following during the pandemic. In April, the company reported its third consecutive profitable quarter for the first time, and Musk's net worth swelled to $155 billion.

Musk's former company PayPal also cracked the list at 134 on the Fortune 500. Musk used the funds from when the company went public to create the companies for which he is now famous, including Tesla, SpaceX and Neuralink.

523. Resideo Technologies- Fortune 1,000

While not quite cracking the Fortune 500 list, Resideo Technologies nearly made the list as a rising star in smart home technologies. The company is the No. 1 global distributor of home security products and employs over 14,000 worldwide. Resideo combines home necessities, including air conditioning, security systems, and water and energy conservation tools to give consumers a holistic product.

The company saw job growth in 2020 despite the pandemic as more consumers spent time at home. Over 15 million systems were installed last year, accounting for $5.1 billion in sales. Resideo bottomed out at the start of the pandemic but saw revenues rise by 10% from January to November 2020, surprising Wall Street investors.

627. Digital Realty Trust- Fortune 1,000

Digital Realty Trust is another global giant that made its way to Austin during the pandemic. The real estate investment entity, which provides data center services worldwide, moved its headquarters to the Texas capital in January 2021 and has since seen revenue grow 32.4% to $1.1 billion just this year.

Only 5% of the company's investments in retail, energy, travel and lodging were at serious risk due to COVID. Although it only employs about a dozen at its Austin headquarters, it has a major footprint in Texas and owns 30 data centers in the state.
