Bring the query to the data,
not the data to the query.
Celato runs governed analyses inside the hospitals that hold the records — clinical notes included. Patient-level data never moves. Only approved evidence comes back.
Federated analytics platform
Run your study
where the data lives.
Celato executes feasibility, cohort discovery and real-world evidence analyses inside the hospitals that hold the records — clinical notes included. Patient-level data never moves. You get governed, reproducible answers in weeks.
No data transfer. No site-by-site export agreements. Full audit trail.
The gap
The patients you need are in data you can't reach.
Claims and commercial real-world data sets miss what actually determines eligibility. The records that hold it sit inside hospitals — behind agreements that take longer to negotiate than the study takes to run.
Invisible eligibility
Biomarker status, prior lines of therapy and clinical rationale live in notes and reports — not in coded claims. Cohorts built without them are wrong before you start.
Access outlasts the question
Site-by-site data-use agreements run for many months and frequently collapse on privacy grounds. By the time access clears, the decision has been made without the evidence.
Feasibility comes too late
Protocols get committed before anyone knows whether the population exists. Enrollment failure is the most expensive way to discover the answer.
For sponsors
Three questions worth asking before you commit.
Each runs as a governed query inside participating hospitals. You never receive patient-level data, and you never need to.
Know the population exists before you write the protocol.
Define the criteria you actually care about — including ones that only exist in notes. Get counts, characteristics and site distribution back as aggregates.
- Eligible patient counts per site
- Which hospitals can realistically enroll
- Criteria tested and revised in days, not quarters
See how your product is already being used.
Treatment outside the approved label is a signal, not an anomaly. Celato surfaces those patterns systematically — the starting point for label extension and for evidence regulators expect you to have.
- Off-label and unmet-need patterns, surfaced systematically
- Pediatric and rare-disease populations others can't see
- Clinician-validated before it reaches you
Longitudinal evidence, across sites, without a transfer.
Effectiveness, discontinuation, adverse events and comparator groups — analyzed where the records live and returned as governed aggregates that hold up in a submission.
- Multi-site cohorts without multi-site exports
- Post-marketing commitments and safety follow-up
- Every query versioned and reproducible on demand
How it works
Governance sits in the path, not around the edge.
Four steps. The hospital approves before anything runs, and only approved aggregates come back.
Define the question
Population, endpoint and follow-up window become an explicit, versioned query plan.
Custodian approves
Each hospital reviews the plan against its own policy and approves, scopes or declines it.
Execute locally
Computation runs inside the hospital. Structured records and clinical notes are standardized in place.
Governed results return
Approved aggregates only, with a complete audit trail from question to output.
A governed bridge between research intent and distributed clinical data.
Live viewComputation is routed to the approved environment, so sensitive records remain inside the hospital boundary. Only the approved aggregate output travels back.
For hospitals and data custodians
Support more research. Give up no control.
Your data stays inside your boundary. You approve every query and every release. What changes is what your institution can do with the records it already holds.
Answer your own questions faster
Investigators size a cohort or test a hypothesis in days instead of through manual chart review.
Become a paid research site
Sponsor-funded studies come to you because the evidence shows your patients qualify — as a research partner, not an unremunerated data source.
Join multi-site studies safely
Participate in multi-center research through the federated network without transferring a single patient record.
Governance & security
Built so the answer is defensible.
Every constraint here exists because a hospital privacy office asked for it. That is what makes the next hospital say yes.
-
No patient-level data transferRecords never leave the custodian environment. Only approved aggregate outputs are returned.
-
Approval before executionEach institution reviews and approves every query plan against its own policy before anything runs.
-
Reproducible by designQuery logic is versioned. Any result can be regenerated and traced back to the question that produced it.
-
Complete audit trailQuestion, criteria versions, policy checks, execution and release are all recorded.
-
Data residency respectedExecution stays within the jurisdiction and infrastructure the custodian already operates.
Get started
Bring one question.
You don't need a data strategy or a signed agreement to start a conversation. Tell us one question you'd ask if access weren't the obstacle, and we'll show you exactly how it would run.
What you'll get back within one business day: a technical overview, a worked example in your therapeutic area, and a straight answer on whether your question is a fit.
