Developing Value Chains with Various Partners

Sun* Group strives to establish strong partnerships with customers, investors and business partners, and develop its value chain ecosystem.

Client Relationship Initiatives

At Sun* Group, we aim to go beyond the client/contractor relationship to procure deliverables and form a partnership with our clients where we jointly pursue success and growth of businesses and services. To this end, we will embrace our clients' businesses and services to truly materialize their vision.
Sun* Group regards the number of stock-type businesses (businesses that offer continued services such as subscription services, as opposed to businesses making only one-time sales) clients and average revenue per user (ARPU) as its two most important KPIs that capture the results of our relationship with the client and value of the services provided to the client. This is because, if the Sun* Group continually contributed to the success and growth in businesses and services of our clients, the contract with the client would also be extended and continue to grow. In addition, we also conduct periodic client surveys to gauge whether our clients would consider recommending our services to other companies.

Partners Relationship Initiatives

The * (asterisk) included in our company name is a symbol used in many programming languages to represent multiplication. Through assembling the most qualified teams for value creation, transcending the boundaries between startups and large companies, and collaborating with people, things, and matters that are seriously tackling social issues, we promote digitalization across industries and launch positive updates to society. In order to make this possible, Sun* Group strives to establish healthy partnerships with business partners, investors and collaboration/alliance partners through fair trade and compliance with all relevant laws and regulations. Accordingly, when entering into contracts with business partners that perform important functions in relation to the delivery of our services, we ask our partners for their agreement to and compliance with relevant laws and regulations and the elimination of anti-social forces.

In addition, as a general policy, we have established our "Compliance Manual" for Sun* Group employees, not only to ensure compliance with laws and regulations, but also to fulfill corporate social responsibility with our business partners and build a relationship of mutual trust and understanding.

As we fully recognize the importance of enhancing our partnership base and developing a value-chain ecosystem for continued growth of the Sun* Group, we are focusing on furthering our relationships with partners through mutual trust by periodically reviewing our total number of business partners, invested companies, and collaboration/alliance partners, etc. as an important KPI. We intend to further enhance our engagement by providing various programs to our valued partners, and strive to promote sustainable management in the value chain and strengthen our compliance initiatives.
