Our History

The story of Gunungmas Group is a story of vision, resilience, and purposeful growth.

The story of Gunungmas Group is a story of vision, resilience, and purposeful growth. It began in 1990, when Ms. Melly Linawati, a talented and visionary businesswoman, established a humble retail shop named Toko Gunung Mas in Dili, East Timor. With a focus on daily necessities and a dedication to customer service, the shop quickly earned a reputation for reliability and trust within the local community. Driven by a passion for business and a spirit of entrepreneurship, Ms.Melly expanded her efforts by relocating and establishing a wholesale distribution company in Kupang, launching Gunungmas Citra Niaga in 1996. This move marked the formal beginning of what would become the Gunungmas Group—a company built on strong values, quality service, and long-term partnerships Recognizing the growing importance of education for future generations, Gunungmas Group diversified into the education sector in 2016, with the launch of Apple Tree Preschool, followed by Stella Gracia School in 2017, offering primary to senior high school levels. The education arm was founded with a commitment to character-building and global learning standards. The group continued to evolve by entering the retail convenience market in 2020 through VOSKI Kiosque, and the after-school enrichment sector in 2022 with the establishment of Rumah Belajar—offering holistic development programs in science, arts, linguistics, and sports. Today, Gunungmas Group proudly operates five Strategic Business Units (SBUs) across multiple sectors—distribution, education, retail, and enrichment—employing over 100 dedicated professionals who share a common vision: to create human-centered, purpose-driven enterprises that serve the needs of both individuals and communities.
