In October 1990, Mamoru Nanamura founded SUB & LIMINAL CO., LTD., a forerunner of SEPTENI HOLDINGS CO., LTD. to embark on the human resources consulting business. After the burst of the economic bubble, however, demand plummeted as companies cut their recruitment costs.
To change our business, we launched the Direct Marketing Business (agency service to send direct mails) in 1993. It grew steadily to build a footing for our group.

In 2000, Koki Sato, the incumbent president and representative director, launched the Internet advertising business as a new business. Our swift response to the expansion of the online advertising market and to constantly changing needs for advertising led to continued steady growth. As a result, our group achieved strong growth. In addition to establishing regional offices, by means of mergers and acquisitions, we stepped into Internet business areas other than advertising, such as mobile content, in order to expand our business portfolio.

We have been focusing our efforts on growing areas such as smartphone ads and Facebook and other social media-related services. We have also commenced overseas operations.
From 2012 to 2015, we established 6 sales offices. Our focus on the mobile, social and global areas helped us to achieve sales and income growth for four consecutive years, from 2012 to 2015.
Meanwhile, in order to develop a new business pillar subsequent to advertising, we have been positively working to develop new businesses. In 2013, we embarked on the IP Platform Business (formerly the Manga Contents Business) in which we undertake the planning and development of our original intellectual property.
Additionally, as of the fiscal year ending September 2016 we have adopted the IFRS (International Financial Reporting Standards) with the aim of facilitating our development as a dynamic global company.
In October 2016, the Group acquired Lion Digital Global LTD, one of the largest digital agencies in Southeast Asia, in order to develop further in the global market where smartphone advertising is expected to continue to grow at a rapid clip.

We focus on the Brand advertising, which needs increase recently, in addition to global expansion and video advertising, which we have focused on, with aim to achieve earning growth.
We concluded a capital and business alliance agreement with Dentsu Inc. on October 30, 2018. Hereafter, we will accelerate growth speed of our group through both organic growth and the alliance, with aim further development.

Under the leadership of the newly appointed Representative Director Yuichi Kouno, we aim to transition to a collective leadership structure while “focusing” on existing businesses centered on the Digital Marketing Business and creating “synergies” within the Group, within the business, and between businesses.
