Investors worry as top executives depart Twitter

An exodus of top Twitter Inc executives has raised concerns about the company’s plans to win more users. Media head Katie Jacobs Stanton, product head Kevin Weil, the head of the engineering division, Alex Roetter and HR head Brian “Skip” Schipper will all leave the company, Chief Executive Jack Dorsey tweeted on Sunday night.

Jason Toff, who heads Twitter’s video streaming service, Vine, also tweeted that he was also leaving Twitter to join Google to work on virtual reality. Dorsey’s tweet did not mention him.
