An undisclosed third party has acquired NanoGram, a US-based maker of small industrial products backed by Japanese strategic investor Nagase.
The deal was revealed in a regulatory filing by former parent NeoPhotonics, which spun off NanoGram and NanoGram Devices in 2002 having renamed itself NeoPhotonics from NanoGram earlier that year. US industrial group Greatbatch bought NanoGram Devices for $45m in 2004.
The spin-off NanoGram has subsequently raised more than $39m of venture funding, including closing its $32m series C round two years ago from Nagase and VC firms ATA Ventures, Bay Partners, Harris & Harris, Institutional Venture Partners, Nth Power, Rockport Capital Partners, SBV Venture Partners, Technology Partners, Global Cleantech Capital, Masdar Clean Tech Fund, Mitsui Ventures, Nanostart, TEL Venture Capital and Yasuda Enterprise Development.
