Dice 

Dice calls itself the career marketplace for people who work in tech, not a general job board. The LinkedIn tagline is Dice: Where tech connects. About copy says you can search or just watch the market, then talk to recruiters who already speak the stack. Headquarters on LinkedIn is Centennial, Colorado, with other sites in Urbandale, Iowa and New York. Lloyd Linn and Diane Rickert launched it in 1990 as a recruiter bulletin board in the Bay Area, moved operations to Iowa, and opened dice.com in 1996. It is a brand of DHI Group, Inc., alongside ClearanceJobs. DHI describes AI-powered marketplaces so employers can match specialist technologists, and so candidates get jobs, data and advice. Today that means personalized job matches, career advice, virtual events and resume search. They also publish the Tech Sentiment Report. Founded 1990. Follower count is under 5 million.
