About Signal
We’re building the buyer-intelligence layer for UK and Irish property.
Tiffany spent sixteen years inside the industry. Matthew builds the solutions. We started Signal because the gap between what estate agents need and what the software industry currently provides is growing every day.
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 quietly turning over for years: why does an industry that runs entirely on relationships and conversation use software designed for filing cabinets? Estate agents are some of the most experienced relationship-builders in any industry, and yet the systems they’re handed treat every buyer as a row in a database. The intelligence is in the conversations and the conversations vanish the moment they end.
Tiffany runs discovery, positioning, and the relationships that make Signal work in agencies.
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 make a slightly better CRM” — it was “what does property’s data layer have to look like when AI agents do most of the searching?” That question is what Signal is an answer to.
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.
Most property software has been built by software people for software people. It looks impressive in a demo and falls apart on the branch floor on a wet Tuesday in February.
The next decade of property won’t be won by whoever ships the prettiest dashboard. It’ll be won by whoever has the cleanest, most verifiable, most behavioural data — because that’s what AI agents will need to trust. Buyers are already starting their property searches in ChatGPT. Estate agents who own a structured layer of buyer intelligence will sit at the centre of that shift. The ones who don’t will lose ground to portals every quarter.
Signal is the buyer-intelligence layer underneath all of that. We sell it to agencies today as a tool that makes their team more effective. We’re building it to be the data infrastructure the whole industry will run on tomorrow.
We’re a small team, working in public, shipping every week, and only quietly serious. If that sounds interesting, come and talk to us.
