Shadoten Implements KUZEN to Streamline Operations and Enhance Support Services

Shadoten Integrates KUZEN for Enhanced English Learning Support



In a significant move towards improving operational efficiency and user experience, Shadoten, an English learning application focused on enhancing listening skills, has incorporated KUZEN, a dialogue design platform developed by KUZEN Corporation. This strategic integration aims to nearly eliminate the monthly administrative workload of around 120 hours, allowing Shadoten to concentrate on delivering quality support to its growing membership base.

Background and Challenges


Founded in September 2016 and headquartered in Tokyo, Progrit, the brain behind Shadoten, provides several services to help people achieve proficiency in English, operating with a mission to foster individuals who can thrive globally. With a robust community of over 10,000 paying members, Shadoten has been effectively using LINE for daily learning consultations and contract verifications. However, the launch of a dedicated application led to manual synchronization efforts between app users and LINE users, resulting in significant administrative burdens.

As membership grew, the demand for efficient automation became pressing. This challenge highlighted the necessity for a streamlined system that would automatically link the app’s database with LINE IDs. The introduction of KUZEN has addressed this need remarkably well.

Transformative Outcomes


1. Dramatic Reduction in Admin Workload


With the effective API integration brought in by KUZEN, the previously manual processes for tagging and managing customer data have been cut down to virtually nothing. Moreover, campaigns that require LINE registration have dramatically improved engagement, achieving an impressive ID linkage rate of approximately 90% among users.

2. Leveraging User Behavior Data for Customization


The resources that were saved due to reduced administrative tasks have been redirected towards refining and optimizing initiatives. By utilizing behavior data, such as weekly audio submission analytics, Shadoten can now deploy targeted communications to users with lower engagement, offering personalized encouragement or incentives based on their activity levels. This tailored approach successfully boosts conversion rates of users to paid plans while also minimizing churn rates.

3. Enhanced Speed and Quality of Support


Thanks to KUZEN's comprehensive one-on-one chat feature, customer information is constantly accessible on the support team's interfaces. This efficiency means that even when different staff members handle content correction and administrative follow-ups, they can quickly retrieve and share relevant customer insights, thereby improving response speed and service quality significantly.

Looking Ahead: Vision and Future Plans


Insights from Progrit’s Shadowing Division, represented by Mitsui and Kaji, emphasize the commitment to supporting customers in their learning journeys through to goal completion. The introduction of KUZEN has created an infrastructure that allows for reallocating resources toward providing better support. They are keen on utilizing this foundation for further advancements in user experience, such as converting accumulated learning data into tailored feedback for each learner. The ultimate goal is to maximize educational effectiveness by merging technology with personal touch, ultimately enhancing customer lifetime value (LTV).
