Prime London agency Jefferies London says its in-house AI assistant has handled more than 11,000 buyer enquiries in recent months, helping brokers cut administrative workloads while responding faster to demand.
The firm’s AI system, J.E.S.S.E. – short for Jefferies Estate Sales Support Engine – has processed 11,178 calls since September 2025, averaging around 1,863 calls per month.
Originally developed internally, the technology has since been deployed to handle all inbound calls and a large share of outbound sales calls.
According to Jefferies London, the system has helped generate 212 property viewings over the same period, while also supporting a number of offers from prospective buyers.
TIME SAVING
J.E.S.S.E. (main picture, inset) is designed to qualify buyer enquiries, understand purchasing requirements and match applicants with suitable listings. It can also book viewings directly into brokers’ diaries.
The platform is capable of handling up to 5,000 calls simultaneously, allowing the agency to respond instantly to enquiries, qualify demand and follow up with buyers when suitable properties come to market.
The agency estimates the technology is saving each partner broker around 10 hours per week – roughly two hours per working day – by managing early-stage enquiries, qualification and appointment booking.
CLIENT OUTCOMES
Damien Jefferies, Founder of Jefferies London, says: “Building relationships is fundamental to our business, especially in Prime Central London, but relationships only stay strong when they’re backed by results.
“In a market where expectations are high and timelines are tight; our clients don’t just want reassurance; they want outcomes.
“That’s why we’re embracing AI in a practical, client first way. If J.E.S.S.E., our in-house AI assistant, helps us move faster, spot opportunities earlier, communicate more clearly, and ultimately secure better results for our clients, then it’s a tool worth using. It doesn’t replace experience, judgement, or personal service, it strengthens it.
“We’ll always be a relationship-led brokerage. We’re simply pairing that approach with smarter systems, so our clients benefit from both trusted advice and measurable results. If AI helps us deliver that more consistently, we’re fully behind it.”
