JLL (JLL GPT)
2023-present
JLL launched JLL GPT, an internal LLM trained on the firm's proprietary commercial real estate data, available to roughly 100,000 employees globally. Use cases include market summaries, tenant-rep deal briefs, lease abstraction, and investor reporting. The platform was scoped tightly to internal employee productivity rather than client-facing automation.
Lesson
Large CRE firms have decades of unstructured data trapped in PDFs. The first-order AI win is making that data retrievable and summarizable for your own people, not building flashy client tools.
