Japanese analytics outfit Fuller has announced the closure of a series C funding round worth $4.2 million.

Investors include Sega, Voyage Ventures, Global Catalyst Partners, Asahi Shimbun (a Japanese newspaper), and two government-related investors that remain anonymous.

Going further

Founded by GREE's former Marketing Manager Shuta Shibuya in 2011, Fuller gathers user data from its own apps and utilises it in App Ape - its own service comparable to App Annie, focused on Japan and South Korea.

With the finances raised, Fuller's priority is to expand its analytics services beyond Japan and Korea - although whether this ambition extends to the US and Europe remains to be seen.

The firm also wants to develop a website-to-app conversion service - known as Joren - that will be for apps what WordPress is for websites.
