Redwood City, California, United States Earli Inc. Full time

About Earli

Earli exists to make cancer a benign experience. Earli does that by turning cancers against themselves: genetically forcing them to reveal themselves early, and then kill themselves – precisely and clearly distinguishable from benign lesions at early stages. Based on original technology from Stanford's renowned Gambhir lab, Earli designs genetic constructs that are injected intravenously that turn cancer cells against themselves. These programmable synthetic promoter-reporter sequences "flip on" like light switches only in dysregulated cancer cells and turn them into "factories." The cancer is forced to produce either an epitope "docking station" for imaging agents, or a cytokine for immune system activation against the tumor. Thus, Earli's platform enables immediate diagnosis and treatment of early cancers, rather than long-term observation that can lead to deadly metastatic recurrence.

Earli's synthetic target expression platform has evolved over five years of deep bioengineering. The system can now detect broad ranges of patient mutations, distinguish between malignant and benign lesions, and offer independence from often elusive natural biomarkers.

Earli has raised $82m in three rounds from investors including Andreessen Horowitz, Khosla Ventures, Emerson Collective, Stanford, Perceptive Advisors, Casdin Capital, Marc Benioff, Sands Capital, Breyer Capital, Tailwinds (American-Korean) etc.

Its Scientific Advisory Board includes Jim Allison (Nobel Laureate, Immuno Oncology), Bob Langer (MIT, co-founder Moderna), Phil Greenberg (Hutch, co-founder Juno), Pam Sharma (MD Anderson), Charlie Rudin (Sloan Kettering), Alan Ashworth (UCSF Cancer Center).
