Twitter, the online-messaging service, said it received a “significant” round of funding led by Digital Sky Technologies, a Russia-based venture firm that has invested in other social-networking companies that have enjoyed surging valuations.
Twitter, which has more than 600 employees, did not disclose how much money it raised. Twitter had been seeking funding at a valuation of about $8 billion, people familiar with the matter have said. The company has been ramping up its bid to become an online-advertising powerhouse. It is on course to generate $150 million in ad revenue this year, research firm eMarketer says.
