The Operating System for
Real Estate Analysis.
EFRON is the AI-powered analysis system by CASE Real Estate — built on ten years of technical consulting practice and the ambition to deliver faster, more consistent, and fully traceable analyses to institutional clients.
AI Analysis,
Built from Passion.
Welcome to a new era.
Technical Due Diligence, CapEx and ESG.
Sound pre-checks before the acquisition decision — fast enough to deliver reliable results before commitment. Fewer wasted investments in due diligence for deals that never close.
Systematic analyses at any depth — affordable and fast. Based on real, property-specific data rather than generic benchmarks.
Built on the expertise of:
Three modules on a
shared data foundation.
Technical Due Diligence
From data room to finished report in three days. EFRON identifies facts, detects gaps and contradictions, generates source-based chapters — and the engineer retains full control at every step.
Auto-CapEx
Maintenance and investment costs derived from documents, on-site findings and normative reference values. Every item with quantity, unit price, urgency and photo documentation.
ESG · Taxonomy · CRREM
Taxonomy conformity, CRREM pathways and refurbishment planning based on the same verified data. CapEx measures and ESG targets are directly linked — every measure feeds into target scenarios, every ESG requirement generates CapEx items.
What sets EFRON apart
from other approaches.
Data Reality as an Asset
The combination of document-based and on-site captured data creates a single source of truth: structured, validated, and exportable to client systems.
Transparent Production
Every step — from extraction through fact-building to calculations — is logged and backed by sources. EFRON does not produce black-box results, but auditable reports.
Depth Over Simplification
EFRON is an engineering tool. To deliver professionally sound results, it works exclusively with technically precise and verified input.
Scalable Without Compromise
Decision-grade analysis at institutional level can be produced with EFRON at any scale and depth on short notice.
Different tasks,
different requirements.
EFRON solves the ones no one has solved digitally yet.
A language model can read and summarize texts. But ensuring all documents are fully and correctly considered, contradictions are systematically resolved, and content is placed in the correct professional hierarchy is not guaranteed. A convincingly worded answer does not replace an auditable process.
Data extraction tools make content processable. EFRON goes a step further — it creates facts about the relevant professional questions, classifies them, verifies and draws conclusions. Including about missing documents and contradictions.
These solutions deliver valuable work at a strategic level. EFRON operates at a different point: where the data foundation is created that such tools build upon. Those who want to improve the input quality of technical data need the analytical depth that EFRON delivers.
Eight steps from
data room to result.
Upload
Entire data room via drag & drop, folder structure preserved.
Processing
Multi-stage pipeline: format detection, AI-powered text extraction, indexing.
Data Review
Document inventory, quality assessment, page-by-page comparison with the original.
Site Reality
On-site findings, project notes and expert context flow into the data foundation.
Drafting
Chapter-by-chapter analysis: facts, gaps, contradictions, risks. Writing begins only after approval.
Expert Review
Cross-chapter consistency check, contradiction detection, chapter chat for revisions.
Q&A
Gap analysis, prioritization, status tracking. New answers update the affected analyses.
Export
Finished report as Word document. Verified data in client-specific formats for third-party systems.
Why should an institutional investor
trust an AI system?
Born from Practice
EFRON was not designed on a drawing board. Ten years of project practice defined the professional requirements — then the technology was built.
Tested on Real Projects
Before EFRON was deployed in live projects, it was tested on numerous real projects: report scope, findings, calculation logic, data coverage, consistency.
Quality Standards Maintained
EFRON was only released when results consistently met the quality level that our clients know from traditional manual processing.
Grown Foundation
The technology stands on a foundation of professional know-how that CASE has demonstrably delivered in consulting for ten years and intends to maintain.
With EFRON we produce auditable results and data, not just convincing texts and graphics. Our quality standards remain the same as in every one of our consulting mandates.
From report to valuable by-product.
The real value lies in the structured, validated data foundation. On-site verified data can be extracted and provided for import into client systems or third-party platforms.
Every system that builds on this data delivers better results — because the input quality is right.
