The deal has been touted as the highest pre-revenue capital raised by a startup in Asia Pacific.
JPMorgan and law company Norton Rose were advisors for the deal, which has also seen co-debt advisers ING Bank and Natixis commit to a senior debt facility.
AirTrunk plans to use the proceeds for the construction of its data centres in Melbourne, and Sydney pegged at $1.7 billion.
The company targets to lead the cloud services space across Asia Pacific.
Founded in 2014, AirTrunk develops and operates large scale wholesale data centres that lead the Asia Pacific market with proven reliability, technology innovation and energy efficiency.
Besides its Singapore headquarters, AirTrunk also has offices in Australia, and Hong Kong.
AirTrunk aims to fully operate its Melbourne and Sydney facilities by third quarter of 2017 designed to offer a maximum of about 130 MW of IT load. It hopes to initially offer 20 MW of IT load on its debut.
The startup intends to also enable its clients achieve quality data services at reasonable costs.
AirTrunk recently predicted that data center capacity in Asia Pacific market will reach $12.5 billion by 2019 as demand for cloud computing continues to surge. It noted many businesses that once ran their technology in-house shift processing power off-site so it can be accessed through the Internet.
The startup has been banking on new cooling and electricity delivery systems to compete well against giants such as Telstra Corp and NTT Communications Corp.
