The company is negotiating a potential takeover with more than one firm

Thomas Clayton, chief executive of Mobile voice social networking, bubbly CEO Thomas Clayton, said the company is negotiating a potential takeover with more than one firm.

Bubbly formerly known as Bubble Motion, known as the "voice version of Twitter," headquartered in Singapore. Users can send and receive voice bubbles in a similar way to Twitter. The service was initially used only by SMS, and later launched with iOS and Android apps.

Many celebrity users use the platform to publish voice updates, possibly by testing songs, or simply chatting, to strengthen their relationships with fans, rather than simply being limited to text as Twitter does.

Bubbly currently has more than 30 million registered users, has been through Sequoia Capital and Singapore Telecom and other investors to finance 50 million of dollars. The basic features of the service are free to use, but they also offer fee-based services to listen to more than 1000 star accounts, most of them in Asia and a handful from Europe and America.

Clayton said that about 30% of the company's registered users are monthly active users, of which 80% have bought fee-based services.
