Entrepreneurial career[edit]

In 1995, Jack Hidary co-founded the IT information portal EarthWeb with his brother Murray Hidary and entrepreneur Nova Spivack.[10] In 1998, they took the company public. EarthWeb's IPO was one of the largest first-day returns in NASDAQ history.[11] In 1999, under Hidary's leadership, EarthWeb acquired the tech career website Dice.com. In 2000, the team renamed the company Dice Inc and then later as DHI Holdings, Inc.[12]

On July 17, 2013, Hidary announced his intent to run as an independent on a new party line called the Jobs and Education Party for New York City Mayor and succeed Michael Bloomberg.[17][18] The New York Times described his political leanings as "socially progressive, fiscally reserved, and digitally savvy," and his primary goals are to better education, foster small business growth and spur employment across all boroughs, and attract companies and investment to New York. One of his primary initiatives is to increase productivity by wiring all of the city’s schools, businesses and neighborhoods for broadband Internet service.[19] Another focus is to increase the number of tech incubators and shared workspaces across the city.[20][21] On November 5, 2013, Hidary lost to Bill de Blasio in the mayoral election.[22]
