About Signal
We’re building Signal — the AI-native operating system for new homes transactions.
Tiffany spent sixteen years inside property sales. Matthew builds the solutions. We started Signal because new homes sales teams are running on workflows that turn four-week deals into three-month ones.
Co-founder
Tiffany Brien
Tiffany spent sixteen years at one of Northern Ireland’s leading estate agencies. She started on the branch floor and worked across rentals, sales negotiation and operations.
She came at Signal from a question she’d been asking for years: why do new homes take three months to complete when the actual work — qualifying buyers, booking viewings, agreeing reservations, exchanging — could be done in four weeks? The answer is always the same: the chase. Sales chasing buyers, buyers chasing brokers, brokers chasing solicitors. Time bleeds out of every gap in the chain.
Tiffany runs discovery, positioning and the relationships that make Signal work inside sales teams.
Co-founder & CTO
Matthew Rea
Matthew is the technical co-founder. He builds Signal himself using AI tooling that didn’t exist eighteen months ago.
He came to property from outside the industry, which turned out to be the right way round. The interesting question wasn’t “how do we ship a slightly better CRM” — it was “why does it take three months to do a four-week job?” Signal is the answer to that question.
Matthew writes about what he’s learning on this site, and is unusually willing to talk to anyone curious about the stack — agency principals, fellow founders, AI researchers, investors. Find him on LinkedIn or drop him an email.
The honest reason
Why we’re building Signal for new homes.
Developers pay site finance every week a plot sits unreserved. Sales teams lose buyers in the gap between reservation and completion. Every additional week of cycle time is a real, measurable cost — in interest, in fall-throughs and in headcount carrying deals that should already be done.
The work hasn’t got harder. The buyers haven’t got slower. What’s changed is that the technology now exists to keep momentum on every transaction at once — qualify in conversation, coordinate without chasing, drive completions while the team focuses on the judgement calls that actually need a human.
Three months to four weeks isn’t a slogan. It’s the cost of waiting another quarter to fix the chase.
