Twitter’s CEO confirmed rumours of a management shakeup at the company, naming the four executives that are leaving and announcing the restructure of some of the teams.

Head of engineering Alex Roetter, head of media Katie Jacobs Stanton, head of product Kevin Weil and head of human resources Skip Schipper “have chosen to leave the company,” Jack Dorsey said in a tweet.

Meanwhile, COO Adam Bain’s new responsibilities will include “revenue-related product teams, the media team and the HR team on an interim basis” and CTO Adam Messinger will take over all of engineering and consumer product, design and research, user services and Fabric, Twitter’s mobile development platform.

“Messinger has a very strong sense of how to bring our development together so we can continue to ship faster and produce stronger work that people will love to use,” said Dorsey, adding that he will partner with Messinger “day and night to make sure we’re building the right experiences.”

The shakeup doesn’t end there. According to The Wall Street Journal, Twitter will  bring in two new board members this week, as part of Dorsey’s condition when he became CEO the second time round that he intended to replace the entire board.

What’s more, the company may also announce a new CMO, potentially Leslie Berland, an executive from American Express, Re/code reported.

Troubled financials
All this comes not long after rumours that Twitter may be acquired by News Corp, though the latter reportedly denied the news.

In Q2 2015, when Dorsey was serving as interim CEO after Dick Costolo stepped down, Twitter’s revenue went up by 61 per cent year on year to $502.4 million.

But Dorsey said he was “not satisfied” with user growth, with core active users only growing by two million quarter-on-quarter, to reach 304 million, its slowest rate yet.

In October, when Dorsey took over, Twitter laid off 336 employees, around 8 per cent of its global workforce, in hopes of putting the company “on a stronger path to grow”.

Later that month, the company launched Moments and increased its focus on video and advertising in an effort to boost results in the future, as it reported another loss-making quarter.

Twitter, which has yet to post a profit, reported a net loss of $131.6 million in Q3 2015, down from $175.5 million last year.

Revenue was $569 million, up 58 per cent year-on-year, but its revenue forecast for the fourth quarter was not very ambitious: around $695 million to $710 million.
