    Message from the Representative

    Our company was established in July 2011 for engineers and creators who want to improve their skills, and for companies who want to develop and utilize their system efficiently.

    As the message of “Work and live as you like”, people with various backgrounds have continued to provide services to customers through a variety of working purposes, with flexible working styles, mainly telework and flex time.

    Within the Classmethod Group, which has an edgy image in a good way, our company has become an indispensable existence by continuing to support our customers without asserting ourselves too much, and I think many people share the same image of us.

    In July 2020, we are celebrating our 10th year of business, and as the second business inauguration, we would like to take on the challenge of becoming a company that can play "Operational Excellence" within the Classmethod Group.

    While maintaining a variety of work styles, approaches and behaviors that continue to support customers, we will actively acquire, familiarize, and expand our “operation” business to the degree of specialization, and so we aim to transform into a company that can take on the “operation” domain.

    The specific services and efforts are as follows. We will proactively develop valuable and effective products.

    ■ Service
    ・Operation, maintenance, support, and management of developed applications, tools, infrastructure, security, etc.
    ・Back office operation management

    ■ Customer value
    ・By proper maintenance and operation, customers can entrust their work to our company and specialize in their main business.
    ・Support customers' management and business through system utilization support and business improvement

    ■ Structure
    ・ISMS (ISO27001), ITIL compliant services (continuing maintenance and expansion)
    ・Thoroughly paperless by utilizing SaaS, teleworking, labor saving (continuing active implementing)
    ・Promote low-cost operations such as offshore and efficiency (continuing expansion)
    ・Documentation of operations, management and improvement of issues, quality, productivity, etc. (continued)
    ・Horizontal expansion of know-how, knowledge, and model actions
    ・Package standard operations and preparing a system for horizontal expansion

    Please note that some of these efforts are still in the planning stage and in the process of being designed, and we will continue to disclose information on released products and successful cases through our website, seminars, and blogs. Please look forward to our new challenges.

    At our company we are actively recruiting mainly people like engineers who want to further extend their skills, those who aim to become engineers in the future and want to achieve results through qualifications and work, those who want to plan and construct or improve the ultimate operation together, those who are currently successful in their work but are thinking of changing jobs. Please take a look at events such as seminars or use job application sites.

    We look forward to your support in the future.
