Ahead of Elon Musk’s acquisition and some uncertainty, Twitter has begun shaking up its leadership by releasing some top executives from their duties. In a thread on Thursday, the head of consumer product, Kayvon Beykpour who is currently on paternity announced he’s leaving the company after seven years. The company also confirmed Bruce Falck, general manager of revenue will be leaving the company.

“The truth is that this isn’t how and when I imagined leaving Twitter, and this wasn’t my decision,” Beykpour tweeted about his departure. “Parag asked me to leave after letting me know that he wants to take the team in a different direction.” In a statement to The Verge, Twitter spokesperson Adrian Zamora said “we can confirm that Kayvon Beykpour and Bruce Falck are leaving Twitter. Jay Sullivan is the new GM of Bluebird and interim GM of Goldbird. Effective this week, we are pausing most hiring and backfills, except for business-critical roles. We are pulling back on non-labour costs to ensure we are being responsible and efficient.” Twitter calls its consumer product team “Bluebird and the revenue team “Goldbird”.

In a memo to Twitter employees obtained by The Verge, CEO Parag Agrawal cited the company’s failure to hit targeted growth in audience and revenue as reasons for the shakeup. Agrawal wrote, “the global macroeconomic environment has become less favourable, the war in Ukraine has impacted our results, and may continue to do so.” He continued by mentioning the uncertainty about the timing of Twitter’s acquisition and said “but leaders will continue making changes to their organizations to improve efficiencies as needed.”

Twitter is not the only company planning on cutting costs. Meta recently stopped some projects in its Reality Labs Division and intends to reduce its investment cost.
