About CohortLayer
CohortLayer is an independent, repeatable audit of the human genetic evidence behind a drug target. Most target-validation work relies on published evidence that is checked once, against a single dataset, and never revisited. CohortLayer was built to do it differently: testing each published claim against independent sources, checking that the direction of effect fits the intended mechanism, and re-running the audit as the evidence changes. The service is developed by a team with graduate and doctoral-level expertise in machine learning and genomics, and is operated by Hansen Consult OÜ, a company registered in Tallinn, Estonia. We work with a small number of biotech, techbio, investor and translational research teams. Access is by request.
Built by people who understand both the data and the biology.
The core team brings together expertise across two disciplines that are rarely combined: machine learning at scale and human genomics. Our genomics work is informed by doctoral-level research in population genetics and variant interpretation. Our data infrastructure reflects graduate-level training in applied machine learning and large-scale data systems. We collaborate with academic researchers in cohort genetics, and those relationships inform both our method and our scientific standards.
A focused service, not a platform with unlimited access.
CohortLayer is intentionally small at this stage. We work closely with each team that requests access, understand their target and their question, and return actionable evidence rather than a data dump. Access is by request. We do not take on work where the question cannot be answered with aggregate, population-level genetic evidence, or where the use case conflicts with the governance terms of the data sources involved.
