In 2013, Gil co-founded Color GenomicsColor Genomics with Othman Laraki. He is also a chairman of the company, and previously held the role of CEO from 2013 to fall 2016. Color is a population health technology company that performs genetic testing for heriditary genes such as cancer and heart disease. They offer testing kits for both physician and individual use. The company is headquartered in Burlingame, California.
In early 2020, Color expanded its testing services to produce testing kits for the virus COVID-19. The company began developing a new, high-throughput lab with a goal of processing as many as 10,000 tests per day with results reported within 24 hours to physicians. Color's tests were able to be processed quickly because they were LAMP-based; most other COVID tests developed in the US at the time were PCR-based. LAMP's distinct difference over PCR is that it uses isothermal amplification and not thermal cycling to amplify the DNA for testing. This saves time and money when processing tests. LAMP tests typically have a lower accuracy rate than PCR because of their simplicity, but Color processes their LAMP tests in a different manner than other companies that makes it more accurate. They first extract and purify the RNA from the test sample in a machine that uses magnetic beads, which concentrates the RNA and makes it easier to get an accurate test result. As of early 2021, Color has since partnered with more than 100 companies, organizations, andprocesses schoolsup to supply or process testing kits, such as United Airlines, the University of Southern California, and the University of California San Francisco. Color also partnered with the city of San Francisco, which helped give the city one of the highest per-capita150,000 COVID-19 testing rates in thetests countrydaily.
