Its de-identification and linkage infrastructure is used by most US real-world data vendors and registries, which makes it the plumbing beneath much of the sector. OnCo links it to oncology EHR and real-world data platforms. Whether tokenised linkage stays private as datasets multiply and re-identification techniques improve is the open question that regulators and patients will keep asking. The real-world data platform page carries the wider debate.","asOf":"2026-09-08","links":[{"label":"Official website","url":"https://www.datavant.com"}],"tags":["supporting"],"related":[],"cancers":[],"sections":["ai-computation"],"technologies":["oncology-real-world-data"],"targets":[],"drugs":[],"companies":[],"institutions":[],"pathways":[],"terms":[],"trials":[],"people":[],"bottlenecks":[],"keyPapers":[],"journals":[],"dependsOn":[],"notes":[],"hq":"San Francisco, CA","country":"US","companyType":"ai-software","website":"https://www.datavant.com","investors":[],"funding":[]},"route":"/companies/datavant/","neighbours":{"section":[{"id":"ai-computation","kind":"section","name":"AI & Computation","route":"/fronts/ai-computation/"}],"technology":[{"id":"oncology-real-world-data","kind":"technology","name":"Oncology EHR and real-world data platforms","route":"/technologies/oncology-real-world-data/"}]}}
