BOARD OF DIRECTORS

CEO
Yujiro Takei

Since our founding, we have focused on “Search” as our core, guided by our purpose: “We change the search. We change your business.” Our mission has always been to create valuable time for our customers through our services.

Today, we stand at a major turning point. We have entered an era where AI serves as the primary interface between humans and computers in every aspect of life and work. We are shifting from an age where humans manually operate tools to one where AI agents proactively deliver optimal solutions. The very definition of “search”—and our way of life itself—is undergoing a dramatic transformation.

To meet these societal demands, we are accelerating our development speed more than ever. We will ensure a wide range of collaboration by providing optimized interfaces at every layer, allowing our partner companies and, most importantly, “AI agents” to seamlessly leverage our specialized functions.

Embracing change, we are evolving our organization with flexibility. By fostering an “agile mindset” in every employee to balance speed and adaptability, we are committed to leading the new era of search.
