industry: REAL ESTATE / EUROPE year: 2026 deploymentModel: on-prem headlineStat: "6 weeks to first deployment" title: "How a 200-agent real-estate firm replaced ChatGPT with on-prem AI" description: "A regulated real-estate firm deployed a private AI assistant on its own servers in six weeks, with zero data leaving the company perimeter."
The problem
The firm had agents using ChatGPT to draft client emails and summarize contracts. Legal flagged it: client KYC and contract data were leaving the company perimeter.
The firm needed the productivity. It also needed the data to stay home.
What we built
We deployed an open-weights LLM on the firm's existing infrastructure, fine-tuned on its own redacted contract corpus, and connected it to its document store via a local retrieval index. The model never makes outbound calls.
The deployment
- Week 1-2: Data assessment + model selection
- Week 3-4: On-prem installation, retrieval index, evaluation harness
- Week 5: Fine-tuning + agent rollout to a 20-person pilot
- Week 6: Full rollout to 200+ agents, ops, and legal
Results
In our deployment, agents handled the majority of inbound contract questions without escalation.Zero data exits the perimeter. SOC 2-aligned controls. Legal is happy. Agents are faster.
