San Francisco

TWITTER Inc is losing four members of its executive leadership team, including its product and engineering chiefs, as the social media company tries to revive growth after its stock lost half its value in 12 months.

The quartet of executives, including product head Kevin Weil and head of engineering Alex Roetter, chose to leave the company and take some time off, chief executive officer Jack Dorsey said in a Twitter post.
