The group will also develop unified design guidelines and act as a department to unify the product user interface across all products by guiding and verifying the execution of design guidelines.
Based in Seoul, Estmob started in 2012 to tackle the problem of how to most efficiently send files between two devices. The company developed Send Anywhere, a peer-to-peer real time file transfer service with more than 43 million users around the world. Popular among users in Japan, Taiwan, South Korea, the United States and the United Kingdom, users utilize the service to collaborate and share digital content in a secure way on any platform through a mobile application or web interface. In 2019, Estmob launched a cloud service, Sendy, that has evolved into a collaborative tool by adding cloud functions on Send Anywhere's powerful technology. Sendy is expanding its range of users mainly around Japan, followed by Korea and the United States. Its monthly active users are rapidly growing to YoY 245% and app downloads to YoY 623%.
Rakuten investment arm Rakuten Capital, through its early stage investment fund Rakuten Ventures, has been supporting Estmob from its first seed round in 2014.
