Jicoo API Implementation Reduces Costs by 6 Million Yen Annually and Accelerates Business Growth
Leverages Co., Ltd. operates a diverse range of businesses domestically and internationally to solve social issues. "Levtech Freelance," the company's agency service for IT engineers and creators, previously used an in-house developed system to schedule career interviews between job seekers and career advisors. However, with a rapid annual business growth of 120%, the maintenance and operational costs of their in-house system ballooned. They faced a challenge where the system's agility could no longer keep up with the speed of the business. To resolve this, they implemented Jicoo, which offers high customizability via API and flexibly handles complex matching requirements. By revamping the interview booking process, they achieved a significant reduction in operational costs and created an environment capable of responding instantly to business changes.

ProblemIncreased Complexity Due to Business Expansion and Ballooning Maintenance Costs Hindering Growth
As the business expanded, the number of engineering professions, domains, and nationwide branches increased, making the conditions for matching career advisors with job seekers extremely complex. The in-house booking system worked well in its initial, simple stages, but years of repeated feature additions resulted in a tightly coupled, overly complex system. As a result, troubleshooting and maintenance required approximately 1 person-month of engineering resources per month (equivalent to about 6 million yen annually) in operational costs. Furthermore, requests for structural changes—such as "creating interview slots for a new domain" or "changing calendar linkages to align with organizational consolidation"—required a lead time of 1 to 2 months for system modifications. This led to a drop in business agility and the risk of opportunity loss due to the inability to provide available interview slots.
SolutionLeveraging External SaaS to Focus on Core Operations and the Ease of API Use
While Leverages holds "in-house development" as a core philosophy, they shifted their policy for the interview booking function. Since it directly impacts business revenue and any errors would cause significant inconvenience to customers, they decided to "utilize external tools that guarantee stability and updatability." In comparing multiple tools, the biggest deciding factors for choosing Jicoo were its simplicity and the high customizability of its API. To meet the company's unique, complex matching logic and flexible requirements for future organizational expansion, it was essential to have an open API that could seamlessly integrate with their internal systems. After thoroughly investigating concerns regarding downtime, they confirmed Jicoo's high SLA (Service Level Agreement) and operational stability, which provided the final push for their decision.
Benefit6 Million Yen Annual Cost Reduction and Agility to Keep Pace with Business Speed
6 Million Yen Annual Cost Reduction and Agility to Keep Pace with Business Speed Since implementing Jicoo, the system has operated stably with no outages over the past six months. This eliminated the previous 1 person-month of maintenance and operational labor, as well as the hassle of unexpected error handling, resulting in an annual cost reduction of 6 million yen. The freed-up engineering resources can now be invested in core projects more directly linked to business growth.In addition, calendar display changes and personnel linkages, which previously required engineering requests and took 1 to 2 months, can now be completed in a single day to a few days just by business-side staff operating the admin dashboard. This brought about dramatic business agility. Slack notifications and Google Calendar registrations upon booking are also handled seamlessly, reducing human errors like integration omissions to zero. By preventing opportunity loss for interview slots and responding to job seekers' needs at maximum speed, Jicoo serves as a powerful foundation supporting Leverages' business growth.
