NetMind
NetMind Technologies was an Internet software company founded in February 1996 by Matt Freivald, Mark Richards and Alan Noble.
The company pioneered Internet change detection and notification (CDN) at a time when most companies were still focused on Internet search.
About
[edit]Origins
[edit]NetMind started at the Tech Farm Ventures incubator in Sunnyvale and then rapidly expanded into a headquarters in Campbell and an engineering office in Santa Cruz, California, growing to 60 employees.
Innovation and market presence
[edit]NetMind was the first company to develop so-called persistent search for automatically notifying users of changed search results, a capability developed only much later in products such as Google Alerts. NetMind's popular "Mind-it" change detection and notification service amassed over 6 million users in less than 4 years. The product was also used by companies like Boeing, eBay, etc. In May 1999, NetMind was named one of Upside Magazine's Hot 100 industry startups.
Acquisition
[edit]In February 2000, NetMind was acquired by Puma Technologies later renamed Intellisync and in turn acquired by Nokia in 2005.
Patents and legacy
[edit]NetMind was granted five US patents in the area of change detection:
- 6,219,818 Checksum-comparing change-detection tool indicating degree and location of change of internet documents[1]
