DayOne

The company's business model is centered on building ahead of demand and creating new market opportunities. DayOne's primary service is providing colocation and customized data center solutions. A key component of its strategy is the proprietary SIJORI (Singapore-Johor-Riau Islands) model, which integrates Singapore's connectivity, Johor's cost-effective resources, and Batam's expansion-ready ecosystem into a regional infrastructure network. This model allows clients to benefit from low-latency connectivity and scalable capacity. DayOne serves clients in industries that require high-performance computing, such as cloud and AI. The company employs a rapid modular deployment process using prefabricated components, which significantly cuts build times and costs, allowing for a greenfield project in Johor, Malaysia to be delivered in 8.5 months.

DayOne's facilities are engineered to support next-generation workloads with features like high-efficiency liquid cooling and intelligent infrastructure management for real-time operational insights. The company emphasizes sustainability by designing renewable-ready infrastructure, using low-carbon construction methods, and pioneering technologies like solid oxide fuel cells in its Singapore facility. As of early 2026, DayOne's portfolio included approximately 480MW of capacity in service or under construction, with an additional 590MW for future development. Its data centers are located in key markets across Asia-Pacific and Europe, including Singapore, Malaysia (Johor), Indonesia (Batam), Thailand (Bangkok), Hong Kong, Japan (Tokyo), and Finland. The company has secured significant funding, raising approximately $3.9 billion across several rounds from investors including Coatue, SoftBank Vision Fund, and The Baupost Group, to fuel its global expansion.
