Overview

Inktomi Corporation was an American Internet software company founded in January 1996 by University of California, Berkeley professor Eric Brewer and graduate student Paul Gauthier. The company grew out of a web-search technology developed at Berkeley and initially became prominent by supplying search infrastructure rather than relying solely on a consumer-facing destination site. HotBot was the first search engine to use Inktomi's search technology, helping establish the company as an important behind-the-scenes provider during the rapid expansion of the commercial Web. The company’s name was derived from Iktomi, the trickster spider of Lakota tradition, and was pronounced “INK-tuh-me.” Its visual identity included a nested, three-color cube logo created by Tom Lamar in 1996. Inktomi positioned itself as an infrastructure provider or “arms merchant” for Internet businesses. Its technologies were used by or supplied to customers and partners including Microsoft, HotBot, Amazon.com, eBay, Walmart, and major Internet service providers such as AOL. Inktomi’s original search business expanded into adjacent areas. The company developed Traffic Server, a proxy server and Web-cache platform designed to handle World Wide Web traffic and on-demand streaming media. The system could transcode images into smaller files for users connecting through dial-up services, making it relevant to large ISPs managing bandwidth and performance. Inktomi also pursued shopping search, enterprise search, load balancing, content distribution, video workflow, and live-streaming software through a series of acquisitions. The company went public in June 1998, raising $36 million. Its strong position in search led to partnerships involving Microsoft, Yahoo!, and Disney. Between 1998 and 2001, Inktomi made several acquisitions, including C2B Technologies for shopping-search capabilities, Impulse Buy Network for merchant coverage, Webspective for distributed-server content management and load balancing, Ultraseek Server from Go.com, FastForward Networks for live-streaming distribution, the Content Bridge business unit from Adero, and eScene Networks for video-content workflow and publishing. Inktomi’s growth was closely tied to the Internet investment boom. Its share price reached a reported peak of $241 in March 2000, but the bursting of the dot-com bubble weakened the company’s financial position and market prospects. In 2001, a publicly accessible database containing more than one million spam websites exposed weaknesses in the handling of one of the company’s search-related data resources. In 2002, Inktomi was restructured under the leadership of Keyur Patel. The company sold its Ultraseek Server business, renamed Inktomi Enterprise Search, to Verity and focused on a smaller set of infrastructure assets. Yahoo! acquired the remaining company for $1.63 per share, or approximately $241 million, in a transaction completed on March 19, 2003. This ended Inktomi as an independent public company and brought its search and Internet infrastructure technology into Yahoo!’s operations. Later technology lineage continued through other owners and open-source projects: Websense acquired technology behind the Inktomi Proxy Server in 2006, and Yahoo! donated Traffic Server to the Apache Software Foundation in 2009. Inktomi therefore remains historically significant as an early provider of large-scale search and network-infrastructure software, even though the original company is defunct.

History

Inktomi was established in January 1996 by Eric Brewer and Paul Gauthier at the University of California, Berkeley. Its foundation was a university-developed Web search engine, and the company’s first significant deployment was HotBot, which used Inktomi’s search technology. Rather than building its identity exclusively around a consumer search portal, Inktomi developed software and infrastructure that could be licensed or integrated by major Internet companies and service providers. The company expanded quickly during the late-1990s Internet boom. It raised $36 million in a June 1998 initial public offering, and the performance of HotBot helped attract relationships with Microsoft, Yahoo!, and Disney. In September 1998, Inktomi acquired C2B Technologies for $95 million in stock, adding shopping-search capabilities. It followed that transaction with the April 1999 acquisition of Impulse Buy Network, which brought roughly 400 merchants into its shopping-engine operation. In November 1999, it acquired Webspective for $106 million in stock. Webspective’s technology supported the management of content across distributed servers and was intended to strengthen load balancing. Inktomi also pursued a broader Internet infrastructure strategy. In 1999, chief executive David Peterschmidt described the company as an “arms merchant” for content-delivery providers. Its revenue model could involve a percentage of sales and/or pay-per-click arrangements. The company’s Traffic Server product served as a proxy server and Web cache for ordinary Web traffic and on-demand streaming media. It could reduce image sizes for dial-up users, making it useful to ISPs seeking to conserve bandwidth and improve response times. Traffic Server was deployed by large providers including AOL. The acquisition program continued into 2000 and 2001. In August 2000, Inktomi purchased Ultraseek Server from Go.com, the Internet business associated with The Walt Disney Company. In September, it acquired FastForward Networks for $1.3 billion in stock. FastForward specialized in software for distributing live streaming media through application-level multicast techniques. In December 2000, Inktomi acquired the Content Bridge business unit from Adero, linking the company to a broader content-delivery initiative. In July 2001, it acquired eScene Networks, whose software supported the management and publication of video content. The company’s trajectory changed after the dot-com bubble burst. In March 2000, its stock had reportedly reached $241 per share, but the collapse of Internet-sector valuations placed pressure on its acquisition-led expansion and business model. In October 2001, Search Engine Watch reported that Inktomi had accidentally exposed a database containing more than one million spam websites. The database could be reached through a search result on the competing AllTheWeb service, and the episode illustrated the operational and reputational risks surrounding large search indexes and anti-spam systems. In 2002, Inktomi was restructured under Keyur Patel, who joined the company as an investor and senior vice president responsible for strategy, marketing, and technology. The restructuring narrowed the company’s activities. Its Ultraseek Server product was renamed Inktomi Enterprise Search and sold to Verity in late 2002. Inktomi then agreed to sell the remaining business to Yahoo! for $1.63 per share, or approximately $241 million. Yahoo! completed the transaction on March 19, 2003, bringing Inktomi’s remaining search and infrastructure assets into Yahoo! and ending the company as an independent entity. The technology associated with Inktomi continued to circulate after the acquisition. In 2006, Websense acquired technology behind the Inktomi Proxy Server and modified it for inclusion in the Websense Security Gateway. In 2009, Yahoo! donated Traffic Server to the Apache Software Foundation. As a result, Inktomi’s corporate history ended in 2003, but parts of its technical legacy continued through commercial security products and an open-source Apache project.
