The latest operational analysis from Jefferies London has revealed that its in-house AI assistant, J.E.S.S.E., has handled more than 11,000 buyer enquiries since September 2025, helping the firm respond to demand faster while significantly reducing the administrative workload of its brokers.
Whilst the technology has been in development and operational use for some time, since September of last year Jefferies London has deployed J.E.S.S.E. to handle all inbound calls and a large proportion of its outbound sales calls.
The internal figures from Jefferies London show that 11,178 calls have been handled over the period, equating to an average of roughly 1,863 calls per month.
Over the same time frame, J.E.S.S.E. has helped generate some 212 property viewings, while also supporting a large number of sales offers.
J.E.S.S.E., which stands for Jefferies Estate Sales Support Engine, is designed to manage both inbound and outbound buyer enquiries, understand prospective purchasers’ requirements and match them with suitable listings. The system can also book viewings directly into each broker’s diary.
The technology is capable of handling up to 5,000 calls simultaneously, allowing the firm to respond instantly to buyer enquiries, qualify demand and follow up with prospective purchasers when new listings come to market that match their criteria.
In addition to improving responsiveness to buyers, the system has also delivered notable efficiency gains internally.
Jefferies London estimates that J.E.S.S.E. is saving each partner broker around 10 hours per week, equivalent to roughly two hours per working day, by handling early-stage enquiries, qualification and appointment booking.
Damien Jefferies, Founder of Jefferies London, commented:
“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.”
