Eye-Fi has completed a $20 million Series D round of funding, led by NTT DOCOMO, the largest Japanese mobile operator and a recognised leader in mobile data and content services. NTT DOCOMO joins Eye-Fi as an investor and strategic partner, expanding the company’s distribution and further establishing its mobile partnerships. In April, NTT DOCOMO will become the first partner to launch Eye-Fi card activation via mobile phones. This new technology means NTT DOCOMO’s 59 million mobile subscribers can quickly and easily share high-quality images between their digital cameras, mobile devices, online photo sites and digital photo frames. The funding round also supports the expansion of Eye-Fi’s executive team, adding former Skype and eBay executive Michele Don Durbin as Vice President of Marketing.
