LEXINGTON, Mass.--(BUSINESS WIRE)--Feb. 1, 2001

Excelergy Corporation, the pre-eminent provider of software technology and products for restructuring global energy markets, today announced it has received $15 million in new equity financing from investors Hummer Winblad Venture Partners, Sigma Partners, Battery Ventures, and Nassau Capital LLC. With this new financing, a total of $63 million of venture capital has been invested in Excelergy since February 1999.

"This is a strong sign of our excitement about Excelergy," said Mark Gorenberg, a partner at Hummer Winblad. "The company has an experienced management team, a large worldwide marketing opportunity, and a business model with a definitive path to profitability. In today's challenging environment for new venture capital, Excelergy is an investor's dream."

Part of the funding will be used to continue the aggressive development of Excelergy's suite of energy software solutions, and part will be used to expand the company's operations globally, according to Excelergy chairman Cary Bullock.

"Since we doubled our revenues in 2000 versus 1999 while decreasing our cash burn rate, our need for new investment capital actually became quite modest," said Bullock. "In the end, we selected the most attractive offer with the best terms for our existing stakeholders."

"The recent turmoil surrounding energy industry restructuring is actually creating new opportunities for nimble software companies that can quickly solve problems by bringing new products to market," said Robert E. Davoli, managing director of Sigma Partners. "Excelergy is also showing extraordinary vision in providing software technology to an expanding set of energy industry sectors, from retail distribution to wholesale trading to transmission, generation and supply." BusinessWeek recently highlighted Mr. Davoli in its July 24, 2000 cover story on venture capital.

R. David Tabors, general partner at Battery Ventures, added, "One of the key things that sets Excelergy apart from its competitors is its exceptional management team. They are experts, they are experienced, and they are successful."
