- Achieving High-Precision Enrichment of Small and Medium-Sized Corporate Data, Advancing Data-Driven Marketing Strategies -

freee K.K.

uSonar Co., Ltd. (Headquarters: Shinjuku-ku, Tokyo; President and CEO: Katsuhito Nagatake; hereinafter "uSonar") is pleased to announce that freee K.K. (Headquarters: Shinagawa-ku, Tokyo; CEO: Daisuke Sasaki; hereinafter "freee") has implemented uSonar's corporate strategy platform, PLANSonar.
Through this implementation, freee will utilize the 12.5 million-record corporate database "LBC" integrated into PLANSonar to enhance data maintenance and attribute enrichment. Specifically, this enables the organization of Salesforce data by corporate number and branch location, as well as high-precision enrichment of corporate information. Furthermore, it contributes to the advancement of segment design and personalized initiatives through the utilization of a Customer Data Platform (CDP).

Challenges and Objectives Prior to Implementing PLANSonar

Overview of freee and the Mission of the Business Infrastructure Division

With the mission of "Empowering Small Businesses to Take Center Stage," freee provides a back-office support platform including "freee Accounting" and "freee HR" for clients ranging from sole proprietors to mid-sized enterprises.

The Business Infrastructure Division, which led this implementation, is responsible for supporting freee's sustainable business growth through both "data" and "systems." Their mission is to maintain the data infrastructure centered on Salesforce and to plan and execute marketing initiatives using a CDP, ensuring that departments such as marketing, sales, and customer success can provide the optimal customer experience at the right time.

Background of Implementation: Seeking a Breakthrough to Reach Untapped Segments

The Business Infrastructure Division previously focused its customer acquisition strategy on digital media, but this approach began to show limitations in the customer segments it could reach. To deliver value to the many small businesses that have yet to encounter freee, a new strategy for acquiring new customers was required.

When considering this new strategy for customer acquisition, the following challenges were identified:

• Existing corporate database products had low attribute enrichment rates for small and medium-sized enterprises, making it difficult to execute precise, segmented initiatives.
• Account data within Salesforce lacked sufficient identification by corporate number or branch location, resulting in a lack of data uniqueness, cumbersome management, and an increased operational burden.

As a result, initiatives utilizing internal data were not yielding sufficient results, and the manual effort required for data organization led to increased costs and operational burdens.

Reasons for Choosing PLANSonar

1. Evaluation Point: Comprehensive Coverage of Business Locations and Extensive Data on Small and Medium-Sized Enterprises

The primary evaluation point was the overwhelming comprehensiveness of the corporate database (LBC) held by uSonar. We highly valued the fact that it accurately captures corporate information with high precision, particularly for small and medium-sized enterprises, which are freee's target market—a feat other tools could not achieve.

2. Data Integration Centered on Corporate Numbers (Keeping Salesforce Always Current and Clean)

The mechanism to keep data within Salesforce current and clean through integration based on corporate numbers aligned perfectly with our data-driven strategy.

3. Perspective of Consideration: Differences in Characteristics of Existing Database Services

During our comparative review, we emphasized the differences in characteristics compared to the database services we were already using. The service we previously used was based on credit data, which is very strong for companies of a certain size, but it was insufficient for data on small and medium-sized enterprises and newly established companies, which are the core targets of our current strategy.

4. Reason for Decision: Directly Linked to the Mission of "Quickly Capturing Newly Established Companies"

"For us, supporting small businesses, quickly catching the birth of each newly established company is directly linked to our mission." With this in mind, we were convinced that uSonar, which can dramatically improve the data enrichment rate for small and medium-sized enterprises, was the optimal partner, and we decided to proceed with the implementation.

Comment from Nobuaki Hiratsuka, General Manager of the Business Infrastructure Division, freee K.K.

Through the implementation of PLANSonar, we have been able to organize our Salesforce account data into a more consistent format, and the precision of the corporate attribute information that serves as the foundation for segment design is improving.
