Major Corporations 

1. Apple

As one of the most successful companies on the planet, it should come as no surprise that the tech giant Apple sits at the top of this list. Located in Cupertino, the company currently has a market cap of over $1,206 billion. The tech hardware and software company has had many successful projects over the years. Its most well known is most likely the iPhone. In 2019, the company also branched into the world of video streaming with a variety of its own content on the streaming platform Apple+. The company also broke into the financial sector during 2019, with the introduction of the Apple Card. 

2. Alphabet/Google

This company seems to rank near or at the top of the list for almost every tech city in the world, and for a good reason! Google (owned by parent company Alphabet), is the world’s largest internet search engine. The company has transformed from a mere search bar on a computer to one of the most powerful ad and marketing companies in the world. The company currently has a market cap of over $867 billion. Google is also hailed as one of the best places to work in the world, with a variety of major perks and high salaries available for employees. 

3. Facebook

Facebook is arguably the world’s most successful social media company. Located in San Mateo County, the company’s headquarters are centered in the heart of Silicon Valley. Founded in 2004 as a college networking app, the company has since grown to a market cap of $561 billion. The company surpassed 1 billion users in 2012, making it the first social media platform to achieve such a feat. Today, there are over 2.4 billion users on the platform. That’s nearly one-third of the entire planet’s population.

4. Wells Fargo

By far the oldest company on this list and even one of the oldest in California, Wells Fargo was founded in 1852 (only 2 years after California became a state). Headquartered in San Francisco, the company has a market cap of $229.9 billion, which is the highest out of all U.S banks. This number may come as a shock given that Wells Fargo is only the fourth largest bank in the U.S in terms of assets. While technically a finance company, Wells Fargo established itself as a major player in the tech industry and has been at the forefront of the FinTech (finance and technology) industry.

Located in Palo Alto, Rubrik specializes in cloud data management. Founded by former Oracle, Facebook, and Google engineers, the company works hard to establish itself as a major industry player since its inception in 2014.
