Mitsunaga Kikuchi is the CEO and Founder of Shirofune, an automated advertising management tool that maximizes the efficiency and productivity of major digital advertising platforms. He joined CyberAgent, the largest digital agency in Japan in 2006 as a new graduate and in a few years, became the Director and the representative of a subsidiary (CA Advance). There he was responsible for providing the in-house ad management system and operational scheme to hundreds of Ad managers at CyberAgent. From the experience at CyberAgent, he then decided to develop a platform which automates the works done by those Ad managers so that anyone, with the limited knowledge, could get the same results from online advertising as what a professional Ad manager brings.
