San Francisco - Twitter on Monday reported a quarterly loss as revenue more than doubled and the number of monthly users climbed.
The San Francisco-based one-to-many messaging service posted a net loss of $175.5m on $361.3m in revenue in the three months that ended on 30 September.
Meanwhile, the number of monthly users grew 23% from a year earlier to 284 million, matching the expectations of analysts.
"We had another very strong financial quarter," Twitter chief executive Dick Costolo said in a release.
"I'm confident in our ability to build the largest daily audience in the world, over time, by strengthening the core, reducing barriers to consumption and building new apps and services."
Twitter shares fell more than 8% in after-market trades that followed release of the earnings figures.
