“Aetheria turned 14 messy sources into one governed model. Month-end close dropped by a week, and audit prep is no longer a fire drill.”
Clara Jensen
Data Governance Lead
This engagement focused on harmonising climate and energy data scattered across departments. Aetheria deployed a governed data warehouse with lineage tracking, API access, and ready-to-query tables.
Creative challenges
The challenge was aligning different taxonomies and incomplete records across legacy systems. Our solution established a central ontology, RBAC controls, and API connectors.
By adopting common definitions, we achieved 98% completeness across 14 sources.
User experience focus
Analysts now query via a single endpoint and generate assurance-ready reports.
Month-end close improved by −7 days, reporting time cut by 54%.
