Sigfox, a France-based company using cellular networks to help build an internet of things, has raised $115m in a series D round backed by telecommunications companies Telefonica, SK Telecom and NTT Docomo.
Reporting the news earlier today, Techcrunch also listed energy utility GDF Suez, industrial gases company Air Liquide, and satellite service provider Eutelsat, as well as Elliott Management Corporation, the management affiliate of hedge funds Elliott Associates and Elliott International, as investors.
Sigfox previously raised $20.7m in a March 2014 series C round that featured Intel Capital, the corporate venturing arm of computing company Intel, and which was led by investment firm IDInvest and French government-backed fund Bpifrance. The round also included Elaia Partners, IXO Private Equity and Partech Ventures.
Intel Capital led Sigfox’s series B round in 2012, which raised $12.8m and also featured IXO, Partech and Elaia. The three firms previously backed a $2.6m series A round in 2011.
Sigfox is building dedicated networks which only send data from internet of things-connected devices, avoiding strains on traditional mobile phone networks.
The company has already deployed its technology in France, Spain, the UK and the Netherlands, and will use the new funding to expand across Europe, the US and Asia.
