Bhavin Turakhia, CEO of enterprise messaging application Flock, will invest a further $25 million in the company. Turakhia had initially invested $20 million in the company and has been positioning the service as competition to Slack messenger. The company will be using the funds for international expansion in the US, Brazil, the UK, Russia, and Spain. Flock will also be adding native language support in each location.

“Surveys and interviews with our global users clearly demonstrated that over 80% of professionals prefer using software in their native language. We immediately made it a priority to develop multilingual support for our users worldwide,” Turakhia added in a statement.

The latest version of the app comes with Public Channels to make it easier for users to discover and join conversations that interest them, within the team. It also introduces two native apps to help users improve efficiency and task management – Shared To-Dos to create and assign tasks, with due dates and My Favorites, to bookmark important messages, files, or links in a chat.

Turkhia is a serial investor and his current ventures include VoIP calling app Ringo, digital tax-saving solutions business Zeta, and internet domain name registration company Radix.

In August, Bhavin and his brother Divyank Turakhia sold their advertising technology company Media.net for $900 million to a Chinese Consortium led by Zhiyong Zhang, the chairman of Beijing Miteno Communication Technology Company, a technology, media and telecom business.  Media.net would continue to operate under Divyank Turakhia and its current management team and retain the business model.

Other exits by Divyank and Bhavin Turakhia: HostGator owner Endurance International Group completed the acquisition of Directi’s web presence business for $109.8 million in a cash & stock deal in January 2014, after initially agreeing to buy it August 2013. The deal included $82.6 million in cash and around $27.2 million worth of Endurance International’s common stock (2.27 million shares at $12 per share).
