Its called a Synthetic Biopsy. It can then localize the cancer in a PET scanner. Earli has been funded by Andreessen Horowitzs Bio Fund, Khosla, Perceptive Advisors, Casdin Capital, Sands Capital, Marc Benioff, Menlo Ventures, ZhenFund. Earli is based in the West Coast’s prime biotech hub in South San Francisco.
