A cairn is a stack of stones. Markers laid by the people who came before, showing the safe path.
We built Cairn because we watched too many safety teams Google their way through OSHA enforcement data that was never designed to be searched. The data is public. The expertise to use it is not.
Cairn unifies the federal compliance record: regulatory text, agency interpretations, enforcement history, and adjacent safety research. One cited surface. Ask a question in plain English. Get an answer with citations to the same documents the agency's own field staff reference. Read the source yourself.
We are the research layer underneath your EHS platform. The part that answers "is what we're doing legal, and how do I prove it?"
We are headquartered in Boston, with safety practitioners and engineers spread across the US. Our customers are industrial firms: manufacturers, builders, operators. They don't have time for marketing copy. So we don't write much of it.
Authoritative sources, primary references only.
Cairn's corpus is built from authoritative public datasets. We don't scrape secondary sources, we don't ingest third-party "compliance content," and we don't alter the underlying records. Citations link back to the original document.
Cairn covers enforcement histories, regulatory text, agency interpretations, and adjacent safety research, all drawn from public federal sources. Ask a question, get answers grounded in the same record the agency's own field staff reference.
A complete list of underlying datasets, refresh cadence, and licensing is available under NDA. Ask sales for the data appendix to the MSA.
What we promise.
Claims are cited.
If Cairn can't ground an answer in a public source, the answer says so. We would rather return "I don't know" than fabricate.
Customer data is never used to train models.
Your queries, chats, facility list, and LOI drafts never touch our model training. Stored in your tenant only.
We don't replace your safety judgment.
Cairn is a research tool. It surfaces the standards, citations, and precedent. The decision is still yours, and we make sure you can defend it.
