Founder & CEO

Shinya Takei

I am happy to say that our services are being used by various customers, including some of Japan’s leading companies and the Japanese government. Among them, our main service MARS FINDER has also improved along, and is supported by our clients even nowadays. As IT industry changes in a very fast pace, we stand solidly at where we are.

Under such circumstances, since 2020, we have been blessed with the opportunity to redefine our own value as the new coronavirus spreads around the world. While slightly denying the pride of being the best in Japan that develops a search engine in-house and covers patents, we released AIMY Screen. With the concept of no search keyword, no content-based search result page (URL) units, AIMY Screen will once again bright fresh air into the industry.

We redefined our social value as

“An agent who knows your customer’s website and visitors well.”

I truly believe that advanced technology can be used comfortably even without having advanced knowledge and that the things produced by such technology will sometimes lead to “excitement” that goes beyond “practical use”. It was based on this concept that in 2012 we set forth the following definition in our “MARS WAY” credo:

“Beyond Emotion. Making search technology exciting.”

Based on this credo, we aim to support client companies’ digital marketing activities and help them to provide business globally. You can expect various emotions when your vision is combined with our patents, technologies, services and – more than anything else – the passion of our employees.

Shinya Takei

1971 Born in Matsumoto, Nagano Prefecture

  • Japan National University of Tokyo (UTokyo) industrial Principal Investigator
    Unified Multiple Projects – JUST, Graduate School of Information Science and Technology.
  • UK National University of Wales Graduate School of Business MBA graduates
    University of Wales (UK), MBA/MOT
    Admitted to the degree of Master of Business Administration, Credited Auditors of Management of Technology and Innovation.

Takei’s grandmother ran a beauty salon, his grandfather as a photographer, father as an engineer, and  mother as an artist. He grew up in Mihama-ku, Chiba City, and raised up surrounded by photography, music and computers since childhood. In 1989, a 17-year-old personal computer host station opened. At that time, computer communication was slow, and Takei’s own room became a “hangout place” where early-stage computer nerds gathered offline, and a large amount of data was distributed from this room. Based on the needs of data exchange, programming with friends to recommend data that suits individual tastes, detect duplicate data, and automatically classify data. The source of technology that is still in business has been developed since this time.

Takei participated in Ray, an event and video production, involved in the early days of Web production. Prior to Ray’s initial public offering, Takei started a search engine research and development company, the company that became the predecessor of MARS FLAG. In 1999, he founded an ad auction site “Cybercom Co., Ltd. (Ad Marketplace Inc.)” with Masatoshi Kumagai and Yoshiteru Akita, GMOs, and became a director. In 2001, she was listed on NASDAQ Japan as DAC (Digital Advertising Consortium) and resigned as a director in the same year.

Takei is deeply knowledgeable in Southeast Asia, partly due to the father of the general contractor engineer. As of now, Takei has a nomadic lift style, which he swifts between Tokyo, Shanghai, and Singapore.

Mitsuyoshi Nishida

“Time” is the most precious element that we can save while searching. In order to acquire the necessary knowledge and new information, the other methods are comparatively time-consuming. With MARS FLAG’s technology, we reduce the amount of time it takes to provide search results and better search experience. This is, we believe, exactly MARS FLAG’s mission as a search specialist when we started with the search portal.

Keep evolving is always important to a company. Our team members’ are fearless of change, and with that, they have made MARS FLAG a very competitive company. With this strength as a driving force, I believe we will continue to provide better services to clients and service users as well as gain the trust of many stakeholders.

Yujiro Takei

Sooner or later, I suppose people might no longer be using the search window or the familiar magnifying glass tool. This is an era where the act of search itself disappears.

As a search platform provider, we would like to be a “Kuroko (stagehand)“, who will penetrate various applications, scenes, and devices by sharpening search functions. Meanwhile, continue to contribute to producing creative times for people. The key to our success is “search”, which has been scrutinized for more than 20 years since our founding. While providing this “search” as an axis, we can evolve freely and constantly to provide various values to today’s society.

We are a company where programmers and engineers shine. To that end, we create a free-form organization that is not bounded by any patterns. Looking ahead to the changing times, we will continue pursuing a mechanism that satisfies experts in this technical field.
