Operational clarity, without the spreadsheet maze.
ECHO45 ADVISORS LLC builds decision intelligence software and publishes practical mobile apps. We focus on governed metrics for teams and simple, local-first tools such as HomeKeep Checklist for household maintenance.
Governed metrics
One semantic layer for definitions, lineage, and approvals — so every dashboard reads the same numbers, always.
Self-serve exploration
Fast, safe slicing for analysts with guardrails that protect sensitive dimensions and prevent model drift.
Deployment flexibility
Cloud or private environments with connector patterns for the systems you already run — no rip-and-replace.
Audit & lineage
Full data lineage from source table to published metric — so every number has a traceable explanation.
Three-layer architecture
A proven pattern: ingest from sources, model governance in the middle, deliver anywhere downstream.
- Connectors for warehouses, DBs, and operational APIs
- Metrics catalog with versioned definitions
- Presentation layers for dashboards and embedded analytics
Security & compliance
