History

108 EVENTS

Our company started as a venture with four employees, launching operations from a 10-tatami-mat office in Asakusa Bridge. At that time, we did not receive applications from immediately deployable engineers, and only occasional applications from IT novices. However, during an interview with an inexperienced applicant, we discovered he was remarkably humble and approachable. This encounter prompted us to focus on hiring IT novices who, even without knowledge or experience, are motivated, proactive, and possess high human qualities. In the course of these efforts, we happened to encounter a person with a disability, which became the beginning of our current diversity employment.Sources

In 2006, we announced and launched the 'ISFnet de Working Squad', which provides IT-related jobs and support to part-time workers and seniors.
