| Earli | Earli is a developer of cancer treatment devices designed to search for natural biomarkers. The company's mission is to make cancer a benign experience. Cancers are detected early when they are homogeneous; and then located early, so they can be treated when the chances of survival are multiple times higher. Rather than rely on biomarkers thatcancer may - or often may not - naturally provide, Earli's technology forces cancer cells to make a synthetic, non-human biomarker using a novel gene therapy approach called Synthetic Biopsy. The early cancer is then visible in a PET scanner. The same platform is also usable for therapeutics. | $40M | Series A | Jan 12, 2021 | https://earli.com |
