MIXTEND Story

MIXTEND history

Chouseisan

「Chouseisan」 was born at Recruit Holdings Co., Ltd.’s Media Technology Lab.
The service grew steadily, and in 2014 it was positioned as a new business, and the predecessor project team was established.

Kitano, who was still a university student at the time, also participated in the project as an intern.
We thoroughly pursued "ease of use," and at times prepared as many as 100 patterns of measures, sometimes verifying them with A/B tests.

Established Mixtend Co., Ltd.

Kitano took a leave of absence from university and was participating in an internship at Recruit. About two years later, the deadline to return to university was approaching, but he decided to drop out because he wanted to continue developing Chouseisan.

As a freelance engineer, I was assigned the role of development director.
Around this time, the idea of ​​transferring Chouseisan's business came up within Recruit, and Kitano founded Mixtend Co., Ltd. to become the recipient of the transfer, and spun out Mr. Coordination and related businesses.

Released 「TimeRex」

After taking over the business, we focused on improving 「Chouseisan」 and 「Chouseisan Calendar」 We continued to pursue "ease of use" and made a number of small improvements.
Amidst this, demand for a schedule adjustment tool for corporations increased, and 「TimeRex」 was released as a 「business version Chouseisan」.

In the two and a half years since its release, 「TimeRex」, a SaaS that specializes in scheduling in business settings, has been adjusted a total of over 1 million times. The number of users is still increasing.

Released 「Chouseisan business」

We have released 「Chouseisan Business」 which is easy for corporations to use and supports hidden ads and advanced security, while retaining the convenience of 「Chouseisan」 which is used by many people to streamline scheduling for private scenes.

In addition, we have released an iOS/Android app for 「Chouseisan」 for individuals, and we are evolving Chouseisan, which has been used by many users for many years for personal schedule adjustment, into the next form.
