San Jose, CA, September 17, 2007—WiChorus, a developer of innovative solutions for WiMAX and 4G wireless core networks, today announced it has secured $15 million in new funding in an oversubscribed round. Led by new investor Mayfield Fund, this financing brings WiChorus’ total venture capital funding to $25 million; previous investors Redpoint Ventures and Accel Partners also participated in the round. WiChorus will use the funding to support trials, enhance product functionality, and expand sales and marketing.

WiChorus also announced that Navin Chaddha, managing director at Mayfield Fund, will join the company’s board of directors. Fellow institutional investors Peter Wagner from Accel and Tom Dyal from Redpoint were appointed to the board earlier this year, along with Basil Alwan, president of the IP Division at Alcatel-Lucent. Chaddha was recently named to the 2007 Forbes Midas List as a top 100 dealmaker.

"WiChorus’ unfair advantage of a patent-pending technology and product and a seasoned management team, coupled with the strong market adoption of WiMAX by operators, positions the company to grow into a market leader for both mobile and fixed broadband wireless," said Chaddha. “With its WiMAX offering, WiChorus also represents the new wave of start-ups with core R&D in the U.S. that are selling into emerging markets, including India, and capitalizing on a big market opportunity."

WiChorus brings true power to WiMAX and 4G networks by enabling operators to deploy large-scale, profitable, and feature-rich broadband wireless networks. WiChorus’ advanced services gateway solutions enable operators to offer differentiated services, monetize the Internet, monitor and control network traffic, manage subscribers and services, and optimize network resources. These advantages enable operators to simplify their networks while increasing revenue opportunities. 

“Our innovative vision and technology have been very well received and are validated by the investment distinguished venture capitalists have made in our company,” said WiChorus President and CEO Rehan Jalil. "With growth in traditional voice services tapering off, next-generation wireless markets offer remarkable growth opportunities for service providers worldwide. Our technology enables service providers to capture this opportunity in a much more profitable way by enabling new services revenues and reducing the cost of deploying and operating these networks. This funding will help us execute our business plan and continue to aggressively pursue our go-to-market strategy.”
