San Francisco: Twitter Inc on Tuesday hired Ned Segal, senior vice president of finance at Intuit Inc and a former managing director at Goldman Sachs Group Inc, as its chief financial officer beginning in late August. The appointment of Segal, 43, comes as investors are demonstrating renewed optimism in Twitter, which still lags rival social network Facebook in terms of size and profitability. Anthony Noto, who has been serving as Twitter’s CFO and chief operating officer since November, will remain at the company as COO, Twitter said in a statement.
