Gary Alan Kremen (born 1963) is the entrepreneur who founded personals site match.com and registered several premiere domain names in the early days of the internet, including sex.com, jobs.com, Housing.com, and autos.com. Born in the Chicago area, he graduated Niles West High School in 1981, then graduated with bachelor's degrees in both electrical engineering and computer science from Northwestern University in 1985, and an MBA from Stanford University in 1989.
In 1993, Kremen founded Electric Classifieds, Inc. the first company to bring classified ads to the internet. Funded by private investors in November 1994, he launched the online personals service match.com in April 1995. After troubles with venture capitalists over his insistence that the Company serve profitable alternative market segments including the gay or LGBT market, he left match.com in March 1996, remaining on the board of Electric Classifieds. Over Kremen's objections, match.com was sold to Cendant Corporation for $7 million in 1998, and sold by Cendant to Ticketmaster a year and a half later for $50 million, with Kremen retaining a lifetime account on match.com.
From 1995 to 1996, Kremen founded and served as president of NetAngels.com, Inc., an internet profiling and personalization company that suggested web sites to users. He left when NetAngels merged with Boston personalization software firm Firefly Network, Inc. in 1997, and Firefly was sold to Microsoft in 1998 in a reported $40 million deal.
In 1999, he was listed as an equity-holding officer or director of Brightcube Inc.
Kremen is credited as a primary inventor on a 1995-filed patent for dynamic web pages, US patent number 5706434, which he later sold for over $1,250,000. Additionally Kremen holds two other patents: United States Patent number 7,698,219, </ref> · Issued April 13, 2010: Methods, systems and agreements for increasing the likelihood of repayments under a financing agreement for renewable energy equipment; and United States Patent number 7,890,436, · Issued February 15, 2011: Billing and payment methods and systems enabling consumer premises equipment.
Kremen currently resides in the San Francisco Bay Area. He is the founder of residential solar financing start-up Clean Power Finance, Inc. which raised $6.9m from investors in January 2010, $25m for Kleiner Perkins and $75m from Google in September 2011. He is the founding investor and also a board member of CrowdFlower as well as several other companies. He is listed at the Founder and CEO of Sociogramics, Inc. in his LinkedIn Profile.
Sex.com saga 
Kremen took the matter to the courts where he struggled to make a case, on limited resources, against Cohen's multi-million dollar pornography empire.
In the meantime, however, Cohen had profited vastly through the property and Kremen tried to wrest back some of these profits through further court action. He was awarded a judgment of $65 million against Cohen, but Cohen fled to Mexico and moved the money offshore. Cohen's ex-wife and step daughter were instrumental in this. Kremen did successfully obtain Cohen's Rancho Santa Fe mansion, where Kremen relocated to after the court case resolved. Kremen also successfully litigated against Network Solutions.
