Per the Verge:
Twitter’s daily user growth hit “all-time highs” during the first full week of Elon Musk owning the platform, according to a company document obtained by The Verge.
Since Musk’s dramatic takeover, Twitter’s monetizable daily user (mDAU) growth has accelerated to more than 20 percent, while “Twitter’s largest market, the US, is growing even more quickly,” according to an internal FAQ obtained by The Verge that was shared with Twitter’s sales team on Monday to use in conversations with advertisers. Per the FAQ, Twitter has added more than 15 million mDAUs, “crossing the quarter billion mark” since the end of the second quarter, when it stopped reporting financials as a public company.
If those numbers are in line with how Twitter reported metrics when it was public, they imply that the service has yet to see a mass exodus under Musk’s ownership. He tweeted on Sunday that, since his deal to buy Twitter was announced, “user numbers have increased significantly around the world.” Twitter last reported 237.8 million mDAUs and a 16.6 percent yearly growth rate for the second quarter.
