What We Set Out to Improve.

Business
Asset Management

A financial business responsible for monitoring ESG requirements across a large portfolio.

Partnership
Focused Product Team

Coretus supported ESG data connections, compliance rules, portfolio monitoring, audit history, reporting, and dashboards.

Goal
Make ESG Monitoring Faster & Easier to Audit

Move from periodic spreadsheet review to a more continuous and traceable compliance workflow.

What We Built
ESG Compliance Platform

A system that combines ESG data, portfolio holdings, rules, alerts, and audit history in one place.

What Was Getting in the Way.

The compliance team relied on spreadsheets and delayed third-party ESG reports, which meant portfolio issues could appear between reporting cycles.

The business wanted a faster way to combine different ESG data sources, check portfolio rules, and create a clear evidence trail for internal and external review.

Stale ESG Information
Older scores could leave the portfolio out of line with current sustainability expectations.
Too Much Reconciliation
Compliance staff spent time comparing data from different providers.
Spreadsheet Risk
Manual audit workflows made it harder to maintain consistent, repeatable evidence.
