LinkExchange
LinkExchange was a popular internet advertising cooperative, similar in function to a webring, originally known as Internet Link Exchange or ILE.
It was founded in March 1996 by 23-year-old Harvard graduates Tony Hsieh and Sanjay Madan. Ali Partovi later joined them as a third partner in August 1996. In November 1996, when the company consisted of about 10 people, it moved from Hsieh's and Madan's living room to an office in San Francisco. In May 1997, the company received US$3 million in funding from Sequoia Capital.
In June 1998, LinkExchange acquired MerchantPlanet, an early shopping cart and credit card application. That same month it also acquired Submit It! Inc., developers of Submit It!, ClickTrade, and ListBot.
In November 1998, when LinkExchange had 100 employees, it was acquired by Microsoft for US$265 million.
