History
editThe company was founded in 2002 by Jeff Ready, Scott Loughmiller, Ehren Maedge, Mike Olson, Phil White, and Jason Collier. It was backed by Sequoia Capital and was acquired by Tumbleweed Communications in March 2004 for US$38.5 million.[1][2][3]
Mark Kvamme led the investment in Corvigo for Sequoia Capital.[4]
The company developed an email filtering technique called Intent Based Filtering (IBF), using artificial intelligence via a multi-tiered neural network sorting engine. The founders were granted U.S. Patent numbers 7,256,654 and 7,653,606 titled "Dynamic Message Filtering" covering the invention of this technique.[5][6]
In February 2004, InfoWorld gave Corvigo's MailGate the highest rating in a comparison between the Corvigo, MessageLabs, and CipherTrust, the leading anti-spam solutions of the time.[7]
