Mizuho Bank, CyberAgent, and FLYWHEEL reach agreement on strategic business alliance regarding marketing platform business

Mizuho Bank, Ltd. (President & CEO: Masahiko Kato), CyberAgent, Inc. (Representative Director: Susumu Fujita), and FLYWHEEL, Inc. (CEO: Naoto Yokoyama) have reached an agreement to form a strategic business alliance involving a marketing platform business designed for corporate clients.

Moving forward, the three companies will begin creating an advertising business, offering platform services, and advancing analysis through data science in an effort to support the marketing activities of corporate clients.

1. Background

People's lives, the economy, and society are undergoing major and rapid shifts in line with changes in social structures due to factors such as declining birthrates, an aging population, and the advancement of digital technologies and digital transformation. Accompanied by this shift, the needs of Mizuho Bank’s customers have diversified, and there is a growing demand for corporate clients to advance marketing in order to deliver personalized products/services to a wide range of consumers.
In Japan’s banking industry, the revised Banking Act came into effect in November 2021 to allow banks themselves to manage new business activities that utilize management resources from the banking business. This in turn enabled services that could further respond to issues faced by corporate clients by way of advertisement, system sales, and personnel placement businesses.

With these efforts in the background, the three companies agreed to form a strategic business alliance to create a marketing platform business that utilizes each company’s strengths to provide support for the marketing activities of corporate clients.

2. Details

(1) Creation of advertising business

Through the utilization of customer information1 entrusted to Mizuho Bank, as well as CyberAgent’s ad delivery model that applies its AI technologies, Mizuho Bank will explore ways of offering optimal information at the appropriate time to fit each individual customer.

1:Highly personal information such as names will not be used in the advertising business. Additionally, personal information of customers will not be provided to the two partner companies or corporate clients (advertisers).

(2) Creation of marketing platform business

By linking the new advertising business with Mizuho Bank’s offering of Mi-Pot2, a statistical data sales service aimed towards businesses, Mizuho Bank will look into construction of a platform that can perform functions from advertisement delivery to analysis.

With this business alliance, both companies will work to utilize their cumulative knowledge, improve analysis/prediction capabilities to provide customers with information fit for their needs, and construct an ad delivery model.

(4) On efforts to protect personal information

Upon the creation of this new business, Mizuho Bank will strive diligently to protect the personal information of customers. Specifically, it will collaborate with FLYWHEEL, which possesses advanced data management technologies as well as knowledge on personal information security, to construct an even safer and more secure structure to utilize information provided to Mizuho Bank with the prior consent of individual customers.
