Company News
uSonar Co., Ltd. (Headquarters: Shinjuku-ku, Tokyo; Chairman: Nami Fukutomi; President: Katsuhito Nagatake; hereinafter "uSonar"), which supports corporate DX by leveraging Japan's largest corporate master data, is pleased to announce that it has entered into a partnership with PIANO Japan Co., Ltd. (Headquarters: Shibuya-ku, Tokyo; Representative Director: Ryo Shioya; hereinafter "PIANO Japan"), the provider of the digital business platform "piano."

Service Overview: Realizing Japan's First * Server-Side Integration
Through this partnership, we have achieved Japan's first server-side integration for a private DMP between "piano dmp," a private DMP for digital media, and "LBC," the largest corporate master data in Japan provided by uSonar.
In this integration, when a page view is received by piano dmp, the IP address of the site visitor is matched against over 40 million IP addresses in the LBC database. This allows for the automatic, real-time appending and storage of corporate data—such as company name, major industry, sub-industry, revenue range, employee count range, and listing status—to the page view data.
* As of July 31, 2023. Based on our research.
Service Features
This integration offers the following three key features.
Feature 1
You can automatically append corporate data, maintained by over 4,000 uSonar staff members, to site visitors (including anonymous users), store it in piano dmp, and utilize it effectively.
This is highly effective for addressing challenges where member data is not held on the site, or where the existing member database is too small to be utilized effectively.
Feature 2
Because all page view (PV) data is matched on the server side, high-precision corporate data can be reliably appended to PVs whenever they match the corporate IP addresses managed by LBC.
Consequently, this minimizes the issue of low data matching rates, which is a common challenge in client-side integrations.
Feature 3
LBC data is not exchanged within the browser, allowing for secure utilization within piano dmp in a highly confidential environment.
Unlike client-side integrations, where matching results with LBC can be viewed within the browser, this integration eliminates such security concerns.
Joint Message
Ryo Shioya, Representative Director and President of PIANO Japan, commented on this partnership as follows:
"I am very pleased that the integration between piano dmp, the de facto standard for major domestic publishers, and the LBC provided by uSonar has been completed.
It is now possible to match rich and accurate LBC corporate data with piano dmp without security risks or data corruption. I am confident that by accurately analyzing and targeting site audiences using corporate data, we will contribute to the improvement of digital advertising revenue."
Daiki Yoshikawa, Executive Officer of uSonar, also commented as follows:
"We sincerely welcome the integration of Japan's largest corporate master data, LBC, into PIANO Japan's piano dmp.
Against the backdrop of the rapid expansion of non-face-to-face business, diversifying needs, and regulations regarding third-party cookies, it has become difficult to estimate the interests and concerns of potential corporate clients.
We expect that by utilizing LBC, the value of the site audiences held by piano dmp user companies will be significantly enhanced."
Looking Ahead
In the digital media landscape, as we approach the cookieless era, the key lies in how well we can understand visiting users and conduct data analysis within the site without relying on third-party data.
The partnership between uSonar and PIANO Japan will further promote data utilization for digital media engaged in B2B business and support the improvement of corporate revenue.
