Jack D. Hidary built his career as an entrepreneur and has been dedicated to public service in education, sustainable energy and economic growth.

In 1995, Jack followed in his family’s entrepreneurial footsteps and established EarthWeb a company dedicated to the needs of tech professionals. Jack co-founded the company with his brother Murray Hidary and friend Nova Spivack. Jack led the company from its inception through three rounds of investment and then its IPO on NASDAQ. Under Jack’s leadership, EarthWeb acquired, a website that connects users with jobs, and other sites dedicated to the needs of IT professionals. As Chairman and CEO of the public company, Jack continued to grow the company and engage with shareholders, customers and analysts. After running the public company for more than three years, Jack handed off to a new CEO. The team later restructured the company, took it private and then took it public on the NYSE as Dice Holdings.

Jack is the founder and Chairman of Samba Energy, a leading marketplace for commercial solar projects and financing. Samba’s marketplace has driven down the cost of commercial solar and thus increased the ROI for companies using the market for their solar programs.

Committed to community and philanthropic causes, he has received several industry and community awards as well as being recognized as a Global Leader of Tomorrow at the World Economic Forum, Davos. He is also a founding member of the Clinton Global Initiative (CGI). CGI was founded by Bill Clinton to bring government together with the private sector and non-profits to solve the big problems of our day.

Jack advocated for the use of high-mileage vehicles as New York City taxicabs in 2005 with David Yassky. David was a NYC council member at the time and today is the Chairman of the TLC. Jack and David successfully engaged drivers who are owner-operators who now save thousands of dollars each year driving high-MPG cars as well as leading fleet owners. Today, the majority of the 13,500 taxis are high-MPG vehicles in NYC helping these small businesses generate more income.

He serves on several boards including the advisory council for the National Renewable Energy Lab (NREL), Google X Labs and is on the board of X Prize Foundation.

Jack studied philosophy and neuroscience at Columbia University and was awarded a Stanley Fellowship in Clinical Neuroscience at the National Institutes of Health (NIH) prior to his graduation. Under the fellowship, he conducted research in functional neuroimaging using techniques such as positron emission tomography (PET) and functional Magnetic Resonance Imaging (fMRI) to study brain and disease states.

Jack was born in the Ocean Parkway Sephardic community near Coney Island. Jack’s great-grandparents came to Ellis Island as immigrants, living in the Lower East Side tenements. Jack’s great-grandfather, Moses Hidary, worked as both a barber and teacher.

In the 1920’s and 30’s Jack’s grandfather Jack Hidary was peddling tablecloths and together with his son Moe founded the family business that is seventy years old and continues to thrive in the garment district. His grandfather moved the family to Brooklyn and co-founded the community that continues to thrive there today. Jack was born at Brookdale Hospital in Brownsville and he and his parents spent his first year living in his grandmother’s house. The family then shared a two-family home with their uncle and aunt before moving to their own house near PS 215 where Jack’s father had attended school. Jack grew up with strong role models and small business owners in a community where everyone had an open door.

Jack’s father, David Hidary, joined the family business and is a very active community member dedicated to education and social services. Jack’s father was president of the local school for 20 years. Jack’s mother is head of the Orange Dance Program, a non-profit program for girls in memory of Mariel Hidary. The family shared a two-family home with their uncle and aunt upstairs before moving to their own house near PS 215 where Jack’s father had attended school.

Jack is the oldest of four brothers and a sister, Mariel Hidary, who was tragically killed at the age of 23 in a traffic accident in 2006. In Jack’s community, it’s family first: the first born is trained to be a leader and take care of the family. Surrounded by strong role models, Jack learned the importance of public service. He saw best practices and started bringing them to other communities.

In 1998, Jack and his brother Murray took their company public when Jack was 30 years old. From the tenements of the lower east side to the floor of the stock exchange is only a few minutes away and yet connects ninety years of the Hidary family history.
