About
The AI-Powered Hub for Real Estate Compliance and Partner Scoring. AI-driven platform for a leading German PropTech to transform unstructured real-estate documents into structured data. By optimizing complex ETL pipelines and RAG flows, we automated partner scoring and compliance. The solution achieved a 10x performance boost, turning fragmented paperwork into audit-ready JSONs and visual analytics, scaling the asset management capabilities
Challenge, approach, and impact
Eliminating Critical ETL Pipeline Bottlenecks
The legacy data pipeline suffered from high latency and sequential processing limits, causing severe backlogs. We re-engineered the architecture to handle high-concurrency document ingestion and implemented asynchronous processing layers. By identifying and resolving these data flow bottlenecks, we achieved a 10x performance increase, allowing the system to transform massive batches of real estate documents into structured JSONs in minutes instead of hours.
Accuracy & RAG Precision in Unstructured Data
Real estate documents in the DACH region are notoriously non-uniform, consisting of various layouts, scans, and legal terminology. A major challenge was ensuring the RAG (Retrieval-Augmented Generation) flow didn't "hallucinate" financial figures. We developed a sophisticated pre-processing layer for document cleaning and a hierarchical RAG structure. This ensured 98% extraction accuracy with 100% traceability to the source, which is vital for audit-ready compliance.
Scaling Intelligence for Multi-Domain Assets
The platform needed to categorize data across diverse asset types - from residential buildings to wind farms - each requiring different scoring logic. We designed a flexible, schema-agnostic data transformation engine. This allowed the AI to dynamically map extracted entities into specific partner scoring models without manual re-configuration.

“When we set the goal of a 10x performance increase for our bison.box platform, we knew it would require more than just technical skill - it required a partner who understood the high-stakes nature of the German real estate market. Kozak Group stepped in and took full ownership of our AI transformation. By automating our document intelligence and partner scoring, they didn't just solve a technical bottleneck, they fundamentally improved our operational scalability. We are now able to provide our institutional clients with audit-ready data at a speed that was previously unattainable. They have turned our vision for an AI-driven asset management future into a robust, market-ready reality. I highly recommend them to any enterprise seeking true innovation backed by reliable delivery :)“

“Our biggest hurdle was the paperwork bottleneck - the sheer volume of non-uniform real estate documents that required manual processing. Kozak Group didn't just provide us with developers; they provided a strategic AI partnership. They re-engineered our core ETL pipeline, achieving a 10x performance increase that we previously thought was technically impossible within our timeframe. By transforming fragmented data into audit-ready JSONs with 98% accuracy, they’ve enabled us to automate our Partner Scoring and scale our operations across multiple new sectors like Energy and Aviation. Their team’s transparency, technical depth in RAG architectures, and commitment to our 6-month launch window were exceptional. They are a top-tier choice for any enterprise looking to turn complex data challenges into a competitive advantage.“
