But these 21 current CEOs are living proof that it isn’t impossible. Some were solo start-up creators, others co-founded a promising enterprise, and a few had to wait a few years between starting their companies and taking the helm. 

Some of these current CEOs are still relatively young, heading up companies capitalizing on new and emerging trends like cryptocurrency and blockchain, with others having spent decades in their role steering companies that have now become institutions. Brian Armstrong’s cryptocurrency exchange Coinbase became the first crypto company to break into the list this year, despite virtual currency’s rough start to 2022 creating some serious headaches for Armstrong’s company.

Several of these companies are on a meteoric rise this year, such as electric car manufacturer Tesla, co-founded by current CEO Elon Musk. The company climbed 35 spots in this year’s rankings, as the electric vehicle industry continues to grow with Tesla at the head.

Other companies have recently made their founders new chief executives, such as FedEx’s Rajesh Subramaniam, or even welcomed back founders to the company as CEOs to handle a rapidly evolving business environment. Starbucks founder Howard Schultz returned to run the company for the third time last March, as the company navigates unionization demands from workers and even a possible foray into the NFT space.

The average age of the founder-turned-500 CEO was 54 years, with some as young as 37 and others as senior as 74. Despite the record-breaking year for women leading Fortune 500 businesses, all this year’s founders-turned CEOs are men, making this founder to CEO track another glass ceiling yet to be shattered.

Chief executive tenures have been becoming shorter in recent years. The average CEO spent 6.9 years in the role in 2020, down from eight in 2016, according to a 2020 survey by recruiting and consulting company M&A Executive Search. The trend carried on into the pandemic, with one report finding that 11.6% of 3,000 companies surveyed had a CEO change in 2020.

Which makes the founders-turned-CEOs of this year’s list stand out even more by bucking the trend and sticking with their companies through the good and bad times, sometimes for decades. Here are the 21 founders-turned-CEOs on this year’s Fortune 500
