About DayOne

DayOne builds and operates hyperscale data centers across nine markets in APAC and Europe. We raised US$4.5B in Series C funding and are in active build across the region. Johor is where DayOne's Malaysian operations are concentrated, at the heart of the SIJORI corridor connecting Singapore, Johor, and Batam.

In 2026, DayOne committed RM28+ billion to Malaysia and secured a landmark partnership with TNB for over 1GW of renewable energy. Functions based here work close to live campuses, which means the work connects directly to the infrastructure it supports rather than sitting at a distance from it.

Nice to Have
