Mango Leads Network Revolution

New Software Company to Deliver Powerfully Simple Networking Solutions

Westborough, MA - May 6, 1997: Businesses have long puzzled over finding a network solution they can easily implement, manage and afford, often resorting to the inefficient "sneaker net." A new company - the MangoSoft Corporation (Mango) - is creating breakthrough networking software solutions designed to meet this overwhelming market demand.

The company will roll out in the summer of 1997 a series of products based on its breakthrough CacheLink network architecture, which provides a powerful alternative to traditional client/server and peer-to-peer network offerings. Mango's flagship product, Medley was created specifically for small business and SOHO environments.

"Mango is breaking all the rules when it comes to networking," said Steven Frank, CEO, president and founder of Mango. "We have engineered a powerfully simple network environment that is adaptive, automated and transparent that can be set up by anyone in minutes. By blending advanced technology with simplicity, Mango is delivering ideal solutions for small business."

Mango's core technology harnesses the untapped power and resources of a desk to PC by automatically leveraging the idle resources of other PCs on the network. The architecture enables shared resources and information from the desktop with a single universal view of all the data on the network. The simplicity of the technology eliminates the need for costly technical support.

"Currently, 75% of all small businesses in the U.S. are not networked due to the high cost and complexity associated with current options," said Richard M. Onyon, vice president of sales and marketing for Mango. "We have developed a solution that eliminates the barriers that have prohibited the widespread adoption of networks in this market segment. That's a boon for the market and a terrific opportunity for Mango."

Mango will initially introduce Medley through a wide range of Value Added Resellers (VARs) and Original Equipment Manufacturers (OEMs) in North America. A retail roll-out is slated for later in 1997, followed by the delivery of Asian and European versions in the fourth quarter.
