Several of the best-known precision oncology companies of the last fifteen years started in its offices.","summary":"Third Rock Ventures is a Boston venture firm whose model is company creation: partners incubate a concept, assemble founding scientists and an interim management team, and fund the company through its first years before it raises from others or lists. Oncology has been a central theme since the firm's founding in 2007, with companies built around genomic profiling, kinase inhibitors, cancer metabolism, synthetic lethality and targeted immunotherapies, and a habit of pairing a therapeutic platform with a diagnostic rationale. Its portfolio pages list current and former companies; portfolio links in OnCo are derived from the startup records that name Third Rock as an investor.","asOf":"2026-09-10","links":[{"label":"Official website","url":"https://www.thirdrockventures.com"},{"label":"Portfolio","url":"https://www.thirdrockventures.com/portfolio"}],"tags":["vc"],"related":[],"cancers":[],"sections":["targeted-therapy","immunotherapy","diagnostics"],"technologies":[],"targets":[],"drugs":[],"companies":[],"institutions":[],"pathways":[],"terms":[],"trials":[],"people":[],"bottlenecks":[],"keyPapers":[],"journals":[],"dependsOn":[],"notes":[],"hq":"Boston, MA","country":"US","companyType":"investor","website":"https://www.thirdrockventures.com","founded":2007,"investors":[],"funding":[]},"route":"/companies/third-rock-ventures/","neighbours":{"section":[{"id":"diagnostics","kind":"section","name":"Diagnostics & Biomarkers","route":"/fronts/diagnostics/"},{"id":"immunotherapy","kind":"section","name":"Immunotherapy","route":"/fronts/immunotherapy/"},{"id":"targeted-therapy","kind":"section","name":"Targeted Therapy","route":"/fronts/targeted-therapy/"}],"company":[{"id":"asher-bio","kind":"company","name":"Asher Biotherapeutics","route":"/companies/asher-bio/"}]}}
