Sangetsu Corporation sells interior products such as wallpaper, flooring, and fabrics, and is currently promoting digital transformation (DX) while advancing company-wide data utilization. As part of this initiative, they aimed to build a sales foundation that leverages data. However, they faced the following challenges in utilizing their existing data:
・ Data was fragmented across various tools, such as Salesforce and business card management applications, making it impossible to grasp the overall picture.
・ The range of customer segments served (business owners, design firms, builders, interior contractors, etc.) is extremely broad, making comprehensive management difficult.
・ Input data was dependent on individual employees, leading to a lack of consistency in registered information and uneven data accuracy.
To address this, Sangetsu Corporation implemented SideSonar and Meishi Sonar to manage customers across the entire market in an integrated manner, building a foundation to promote data utilization through automatic integration with Salesforce.
* New subscriptions for SideSonar ended in February 2025. Its analysis and list creation functions have been succeeded by PLANSonar, and its CRM/SFA enhancement functions have been succeeded by GuideSonar.
* The latest business card management application currently offered is mSonar. Meishi Sonar refers to the former name of mSonar prior to December 2023, or the service formerly known as "THE Meishi Kanri Business" provided by NTT DATA NJK Corporation, which was renamed following the transfer of the service in December 2024.
Implementation Results
① SideSonar and Meishi Sonar are equipped with the LBC corporate database, enabling centralized management of companies across the entire market.
② By automatically integrating SideSonar with Salesforce, a sales foundation was built that allows for the utilization of consistently maintained, up-to-date data.
③ Using Meishi Sonar, connection information linked to companies can be managed collectively.
This enables the automatic integration of customer-related data, allowing for deeper customer understanding and the creation of a foundation that realizes more efficient sales activities.

While we are still in the middle of our journey, we have established a foundation for managing "customers," which is the core axis of CRM, and we intend to realize DX by combining this with various other data. Much of the data we have accumulated over the years was managed in a siloed, individual-dependent manner, and we will use this implementation as an opportunity to connect it to effective data utilization.
uSonar will continue to support our customers in promoting data utilization through data cleansing and the construction of robust system foundations.
