Inside the death of Twitter and birth of Elon Musk’s X

By now, the outlines of the story are well-known: a staff of 7,500 slashed by 75%; a free-speech absolutism that welcomed banned users back to the platform, along with a surge of hate speech and misinformation; an advertising crisis in which more than half of Twitter’s top 1,000 advertisers shut their purses; and a confounding corporate rebrand that replaced Twitter and the familiar tweet with a literal Brand X.

And throughout it all, nonstop drama. Elon Musk, the CEO of Tesla and SpaceX, and the world’s richest person, has defined his conquest of Twitter by innovating on spectacle above all. With each curious or controversial move since acquiring the social media company, Musk’s most successful feat has been forcing the world to pay attention.

Time will tell if Musk’s $44 billion takeover will become a business-school case study in how to rejuvenate a company and pivot it toward a brighter future, or a lesson in how rapidly unrestrained hubris can destroy value. Whatever the eventual verdict, the voices of those who experienced the events firsthand offer crucial testimony about the circumstances, motivations, and actions that shaped the story’s critical moments. And they paint a revealing portrait of life inside Musk’s controversial project, with all the conflicting emotions and perspectives.

Fortune interviewed eight people who were present during key moments of Twitter’s Muskification. We’ve anonymized most names but tried to distinguish individual speakers. We’ve edited their comments for clarity or length when necessary, but otherwise present their accounts in their own words in this oral history of the first year at Twitter under the Musk regime.

It’s Elon’s company now

Within minutes of the acquisition closing on Oct. 27, 2022, Twitter’s senior leadership team is fired by Musk, who famously marched into company headquarters hours earlier carrying a sink (“Let that sink in!” he joked in the video he tweeted of his entrance). For Twitter staffers, the next few weeks will be a blurry jumble of confusion, hope, fear, chaos—and for thousands, after just a few days under the new regime, layoffs. 

The first days

“So much of what was going on we learned as it happened on the service, right? Musk showing up at the office, the sink thing, that moment where he was milling around the coffee bar. All of these were things that moved exceptionally quickly, and employees were just sort of like, huh, okay, I guess that’s happening now.” —Yoel Roth, former head of trust and safety 

“We had a Tesla channel in Slack, and people were starting to say dumb things like, ‘Oh, we’re gonna get Teslas now’ or whatever. But the consensus was that most people weren’t happy. They were worried for their jobs. They were worried for their culture and the environment. And just a very, very low minority were excited.” —X employee 1
