Hazel Analytics is the product of university research that dates back more than twenty years. Future Hazel co-founders Phil Leslie and Ginger Jin were rising economists at UCLA in 1999 when they conducted their famous study (later published in the Quarterly Journal of Economics) on the introduction of restaurant grade cards in Los Angeles County, one of the first major U.S. metros to do so. Given the wide reception of the study in both academia and the private sector, Phil and Ginger continued on with several more projects involving local health departments. Unfortunately, they were prevented from doing any work on a national scale, given that food safety regulation is a highly decentralized function in the U.S. In 2011 they set out to change this by obtaining research funding from the Alfred P. Sloan Foundation to create the first standardized national database of health inspection results, enlisting future Hazel co-founder Ben Bederson, then Professor of Computer Science at the University of Maryland, to help architect the technology infrastructure needed to do such data collection at scale. 

With a preliminary database built and the research period coming to an end, the three collaborators were interested in opportunities to maintain the research output for the benefit of public health. In 2013 they brought in Arash Nasibi, then a UCLA MBA student, to explore options for extending the life of the project. Arash quickly discovered that there was a significant need for visibility and analytics related to health inspection outcomes in food service and retail, especially within large national and global brands. With these findings the team was encouraged by the potential to address such critical pain points in the industry, so they decided to commercialize the research by forming Hazel Analytics in October 2014.
