From raw building data to GRESB-ready in under one week.
ESG OS is the AI-native data platform for real estate operators. Automate GHG calculations, GRESB scoring, and regulatory compliance — from 45 commercial buildings to 88,000 single-family homes.
Trusted by real-estate owners, funds, and operators
The problem
ESG reporting is a manual, error-prone, multi-month grind.
The gap between raw building data and a compliant GRESB submission is enormous — and it gets worse every year as frameworks multiply.
4–12 weeks per submission cycle
ESG teams burn months stitching utility data, chasing property managers, and reconciling spreadsheets — every year, every entity.
Data lives in 6 places
Utility billing portals, PMS exports, broker spreadsheets, billing PDFs. Nothing talks to anything. Re-entry is the job.
60% of properties lack actuals
Resident-paid utilities, missing meters, opaque triple-nets. The gap is filled with guesswork — and that guesswork ends up in your investor report.
Product principles
A new operating system for ESG data.
Three ideas shape every screen, every workflow, and every line of code.
The agent is the interface.
Talk to the Copilot: “Run the utility billing extraction.” “Recalculate GHG for all Texas properties.” The agent IS how you work — not a chatbot bolted onto a dashboard.
Collect once, report everywhere.
A utility reading enters the system once. From that single point: GHG calc, GRESB population, LL97 check, GRI mapping, CDP feed. No re-entry across platforms.
Every number has a receipt.
Click any metric — drill down to the source document, the reading, the versioned emission factor, and the formula. Auditors and regulators see exactly where every tCO₂e came from.
Product tour
What you actually do on the platform.
Run the data workflow by talking.
Extract from your utility billing provider. Normalize meters. Recalculate emissions across a Texas portfolio. The agent orchestrates the work — you review and approve.
Every number drills to its source.
Click a tCO₂e value. See the reading, the source PDF, the versioned emission factor, and the formula that produced it. Regulator-ready.
Built for 80,000 properties — not 80.
Batch imports, multi-entity rollups, and dataset-wide recalculations that don't stall the UI. Designed around SFR portfolio scale from day one.
One dataset. Every framework.
Generate GRESB, GRI, SASB, TCFD, CDP, LL97, and ENERGY STAR outputs from the same canonical model. No re-keying. No drift between reports.
Built for scale
80,000 properties is our design constraint — not 45.
Most ESG tools were built for commercial portfolios of 50 buildings. ESG OS was built from day one for SFR scale — and if it works for 88,000 homes, it works for everything below.
Single-family rentals supported per portfolio
Countries across a single hospitality client
Automation on data extraction & calculation
From raw data to GRESB-ready submission
Frameworks
Map your data once. Report against every framework.
The canonical model maps cleanly to the disclosures your investors, regulators, and certifiers actually ask for.
