Nantero, a US-based nanotechnology developer backed by oilfield equipment provider Schlumberger, closed a funding round yesterday at more than $21m led by Globespan Capital Partners.
Unnamed new and existing shareholders also participated in the round, which increased Nantero’s total funding to approximately $110m.
Nantero is working on semiconductor technology called as high-density high-speed non-volatile random access storage device (NRam) that has applications in mobile devices, desktop computers and enterprise systems.
The funding will go towards helping Nantero’s clients to integrate NRam into their products.
Schlumberger supported a $15m series D round in 2013 alongside at least one other, unnamed corporate backer. Nantero’s shareholders also include Charles River Ventures, Draper Fisher Jurvetson, Stata Venture Partners and Harris & Harris Group, according to its website.
Greg schmergel, co-founder and chief executive of Nantero, said: “The customer traction we have achieved at Nantero has been overwhelming, as evidenced by our recent announcement that NRam had been selected by both Fujitsu Semiconductor and Mie Fujitsu Semiconductor.
“With this additional funding, we will be able to help these existing customers speed their time to market while also supporting the many other companies that have approached us about using Nantero NRam in their next-generation products.”
