Japanese mobile social gaming company Gree is closing its mobile messaging service Tellit as part of an ongoing reorganisation.

Tellit was released as GREE Messenger in December 2012, but a spokesman told The Next Web that the service will stop operating from 1 September as part of the company’s restructure.

“In recent weeks we have been optimising our global operations and product lineup strategically based on a policy of selection and concentration. As part of that process, we decided, after much deliberation, to close Tellit so that we can focus our efforts on other opportunities,” the spokesman said.

The closure brings into question the future of Dutch company eBuddy, which designed Tellit. Gree took a minority share in eBuddy in October 2012.

A number of the company’s ventures aimed at expanding outside of Japan seem to have failed. It also shelled out $210 million on US social game developer Funzio and $109 million on mobile social gaming platform OpenFeint which it subsequently closed in November 2012.

The struggling company closed its UK office last month, less than two months after pulling out of China as part of a plan to optimise its operations through “a process of selection and concentration”.

The company wrote down JPY4 billion ($39.2 million) of assets earlier this year as it streamlined its portfolio.
