Chatwork Inc., a Japanese startup that operates a cloud-based chat tool for business, has announced that it would start expanding service operations to the European region from Luxembourg. This follows its international expansion to North America last year, and the Asian region this past spring.

The Chatwork app was launched back in March of 2011, providing a business chat environment for corporate users, with features like group chat, task management, file management, and video conferencing.

Luxembourg is known for having a very low tax rate, and has succeeded in inviting a number of multinational companies to set up shop there. It’s surrounded by Germany, France, and Belgium, and most local citizens can speak English, Luxembourgish, German, and French. Chatwork has decided to start its European operations here because of these geographical and linguistic advantages. The company was in attendance at ICT Spring 2013, an annual tech startup conference in the country taking place this week.

The startup recently unveiled that it has acquired more than 200,000 users as of this month. In terms of the ratio of paid to unpaid users, Chatwork has performed even better than services like Dropbox or Evernote, which are said to be around 4 to 4.5%. More than 50,000 users visit the service every day, and more than 100 million messages have been exchanged using the platform.

The startup unveiled a screen-sharing feature called ChatWork back in May. And from here, it will be interesting to see how much traction it can build in the country where Skype started its journey.
