Apple cofounder Steve Jobs famously left (or was ousted, depending on who you believe) in 1985, after clashing with CEO John Sculley. 12 years later, Apple bought Jobs' startup NeXT Computer, bringing him back into the fold.
Perhaps ironically, Jobs orchestrated an ouster of his own: Just months after returning to Apple, Jobs convinced the board to oust then-CEO Gil Amelio. Jobs became CEO in 1997, and the rest is history.

Uber founder Travis Kalanick resigned as CEO in July 2017, following long months of scandals for the company.
Kalanick left Uber in July 2017, following a long string of scandals — from a #DeleteUber campaign that saw 200,000 people delete the ride-hailing app, to allegations of a toxic company culture from former engineer Susan Fowler, and more.
Ultimately, things came to a head when Uber's board urged Kalanick to step down. In July of 2017, he did. Since then, Kalanick has been dabbling in various investments, including an initiative to try a new kind of food delivery service.

Jack Dorsey founded Twitter with Ev Williams in 2006. Two years later, Williams fired him from the CEO role — even though it was Dorsey who came up with the idea for the micro-blogging site in the first place.
But this didn't stop Dorsey from founding $31 billion Square, the mobile payments platform, in 2009. Facebook CEO Mark Zuckerberg even tried to hire Dorsey after he left Twitter.
However, in 2015, Dorsey was brought back to Twitter as interim CEO, taking over for former leader Dick Costolo. Not long after, Twitter dropped the "interim" from Dorsey's job title.
