Twitter acquires mobile messaging startup

Twitter has acquired mobile messaging startup Cloudhopper for an undisclosed sum.

Twitter has been working with Cloudhopper for the past eight months, said Twitter’s mobile business development director Kevin Thau in a blogpost yesterday.

Cloudhopper is an infrastructure company that enables Twitter to connect directly to mobile carrier networks in countries worldwide.

The micro-blogging site recently revealed that it has 105 million registered users, with 300,000 new users signing up each day.

Twitter recently launched Promoted Tweets, charging advertisers to write Tweets which appear at the top of results when users search for a particular word.
