Biotechnology Research Menlo Park, CA 1,001–5,000 employees Founded 2016 Privately Held

GRAIL is a clinical-stage diagnostics company applying machine learning and next-generation sequencing to early cancer detection. The tech stack is AWS-native (with heavy security layering: WAF, Network Firewall, EDR, XDR, SIEM, SOAR) and Salesforce-heavy across sales, marketing, and service — indicating a B2B2C go-to-market model targeting healthcare systems and primary care practices. Active hiring is heavily skewed toward sales (28 roles) relative to engineering (8), with concurrent projects around territory expansion, payer reimbursement strategy, and primary care onboarding, signaling a shift from product validation toward commercial scale and market access.
