North Star Tech Oy is a Finnish company that makes research integrity verifiable. Its product, North Keeper, is a verifiability layer for the research lifecycle, built on Microsoft Azure. Research integrity is now a board-level obligation for universities, research funders, and publishers, driven by the reproducibility crisis, fabricated results, and tightening funder mandates. Today integrity is asserted, not proven: ethics approvals sit in filing cabinets, reproducibility lives in a methods section few can rerun, and grant spending is reconciled long after the money is gone. North Keeper runs deterministic checks on the research record and turns each passed check into verifiable evidence. It can prove that identified records met defined integrity controls at a point in time, recorded as evidence a funder, journal, or auditor can verify directly. This is the distinction the product is built on: proof, not assurance. It does not claim that a scientific conclusion is true. The first check covers ethical consent, with reproducibility and responsible spending as deliberate later phases. Each passed check is issued as a tamper-evident, post-quantum-signed True North Certificate and recorded in the True North Registry, a public, append-only record anyone can verify against. North Keeper consumes Microsoft Purview, Microsoft Fabric, and Azure Cost Management as substrate rather than rebuilding them; the owned engines and the registry are what make the evidence independent. North Keeper is a transactable ISV product on the Microsoft Azure Marketplace, with metered consumption pricing and Microsoft co-sell, so customers buy through their existing Microsoft agreement. North Star Tech Oy is based in Helsinki and serves universities, research funders, and publishers across the EU and the Nordic region first, then the wider global research market.
