Then and now: What tech CEOs and founders looked like when they first launched their companies versus today

Bezos founded Amazon from his garage in Bellevue, Washington, in 1994. He attributes his new look partly to working out with a celebrity personal trainer and changing his diet.

Meta CEO Mark Zuckerberg started Facebook from his dorm room at Harvard in 2004.

Gone are the days of the Zuck who famously wore the same thing every day to save brainpower for more important decisions. Instead, Zuck can now be seen sporting graphic tees and chain necklaces.

Part of Zuckerberg's physical transformation also stems from hobbies like Brazilian jiu-jitsu and MMA fighting.

Dell is another member of the college dropouts-turned-tech founders club.

Gates and the late Paul Allen cofounded Microsoft from a garage in Albuquerque, New Mexico, in 1975.

Twitter was founded in 2006. Cofounder Dorsey has been seen with a full beard pretty regularly since departing as CEO and focusing his efforts more on cryptocurrency at Block, formerly Square.

At 73 years old today, Branson's day-to-day life still features plenty of exercise, from tennis and cycling to kite-surfing.
