会社概要Company profile As a "digital creator production company," we aim to establish the social standing of engineers through solving our clients' challenges and through our own products, as a group of true professionals.
 Our company is not simply a staffing company for engineers. Through our Digital Talent Business, Contract Development Business, and Content Property Business, we create work opportunities and career opportunities for engineers, both inside and outside the company.

 Many talented engineers gather at our company, and by clustering our talent, we maintain stable business with more than 300 companies at all times, including major companies such as the Bandai Namco Group, the Recruit Group, and the Rakuten Group.

 Since our listing in 2014, along with the increase in the number of employees, we have steadily achieved growth in our business performance, and in the near future we aim to list on the Tokyo Stock Exchange Prime Market. Going forward, by participating in even better clients and projects, we can enhance the track record of our engineers.
