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.
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.
