Nothing new to set up.

Your team drops PMRs into the file storage you already use: SharePoint, Box, or Google Drive. The data appears in DNK. No new tool, no separate upload step.

Any layout, the same clean data.

No two PMRs are built the same way. Layouts shift between PMCs, between assets, even month to month. Hephaestus structures every one into the same clean data. The expertise is built into the system, not held by a few people.

Ten assets or a thousand.

Hephaestus does the processing, so a growing portfolio doesn't mean a growing team. Onboarding an asset is just pointing it at the reports.

Your data, where you already work.

DNK doesn’t replace your tools. The standardized data flows into Excel, your BI tool, or anything with an API — current, reconciled, yours.
