No5 Real Estate covers the South Coast portfolio: BN postcodes through to HU, residential sales, lettings, and an investor desk. Two sides of the business that look the same on paper and are entirely different in practice.
On one side, outbound. Saturday campaigns to sellers, mid-week nurture to landlords, monthly drops to the investor list. On the other side, inbound. Rightmove, Zoopla, Instagram, Facebook leads, the brokerage office line. A buyer in Marina Quarter who saw the listing on Sunday at 11pm and wants to book a viewing before someone else does.
The old setup forced both jobs through one phone number and one inbox. Outbound campaigns drowned out inbound buyers. Inbound buyers got stale leads from a campaign run two days earlier. The team did not stop, the conversations did.
Two lanes. One AI. The agent walks in briefed.
The brokerage runs two WhatsApp lines as deliberately separate lanes. One for outbound campaigns, one for inbound qualification. Both terminate at the same AI, which threads context, books Cal.com viewings, and routes to the right agent.
Outbound and inbound used to fight for the same line. You would launch a Saturday campaign and lose three serious buyers in the noise. Now they run in parallel. The AI decides what is a buyer and what is a campaign reply, and the agents only see the ones that matter.
Cal.com slots held the second the buyer says yes.
Once the inbound AI qualifies a buyer, Cal.com slots surface inside WhatsApp. The viewing is held against the agent's calendar in real time. The buyer sees the address, the postcode, and the agent name before the chat closes. The agent walks in already briefed on the comp set, the service charge, and the leasehold pack.
Each of the ten Twilio numbers has a defined job, a campaign cohort, or a postcode. The AI knows which number it answered on, replies in the right tone for that line, and routes Slack pings to the agent who owns it.
Cal.com inside WhatsApp is the bit that closed the gap. A buyer says yes, the slot is held the same second, the agent gets the address, the comp set, and the leasehold pack before they walk out the office door.
The results.
85% of after-hours leads captured the same evening.
Outbound campaigns no longer cannibalise inbound buyers. The two lanes run in parallel, both terminate at the same AI, both thread context, and the Sunday-night DMs the team used to lose now book a viewing for Saturday.
£180M in property value placed.
Across the South Coast portfolio, the brokerage moved a portfolio value north of £180M with AI-led qualification on the front end. Agents spend their day in viewings, not on the phone chasing down whether a lead has a mortgage in principle.
74% of viewings booked inside the chat thread.
Cal.com slots surface inside WhatsApp the moment the buyer is qualified. The viewing is held against the agent's calendar in real time. The buyer sees the address, the postcode, and the agent name before the chat closes.
Ten lines, one brain, zero crossed wires.
Each Twilio number has a defined job. The AI knows which number it answered on, replies in the right tone, and routes the Slack ping to the agent who owns the line. A buyer who calls a mobile on a Sunday gets the same brokerage they would get on the office line on a Tuesday.
A brokerage that never loses the Sunday-night buyer.
South Coast real estate runs on two clocks. The campaign clock and the buyer clock. Old setups forced both through one inbox and lost the buyer to the campaign every weekend. The parallel-lane setup at No5 keeps them separate, threads context where it helps, and hands every qualified viewing to the right agent already briefed.
We used to ask which campaign killed the inbound that weekend. We do not ask that anymore.
