Property, made watchable
Every KnokKnok campaign is designed for the way buyers actually discover homes now: cinematic film, short-form social, founder-led tours and a story worth sharing.
Global attention · London expertise
Portals wait for buyers to search. We place your home where attention already exists—through film, social distribution, sharing and a London-connected global network.
Domestic movers, relocating families and London-connected buyers discover a campaign wherever they spend their attention—not only when they open a property portal.
Portals list property.

Property intelligence · without the noise
The BriefMark’s weekly interpretation of the London market, the economy, mortgage conditions and policy—with the practical consequence for sellers and buyers.
Mark’s View
The economy is proving more resilient than expected, but that strength may keep mortgage rates higher. Meanwhile, London’s houses and flats are behaving like fundamentally different asset classes. For sellers, identifying which market they are actually in has become critical.
Founder-led. Always.Now here’s the story
After working for Knight Frank and Hamptons Private Office—selling everything from family homes in South West London to a near-£70m trophy property—Mark Breffit decided to build the agency he felt the market was missing.
“We won’t just list. We’ll launch your home like it’s a brand.”Talk to Mark ↗Meet the founder →
Proof, not promises
Selected signals from a career spent positioning London homes with precision.
Selling our flat from overseas felt incredibly daunting, but Mark made the entire process as smooth and stress-free as possible. Communication was exceptional throughout.
Your move
Give us the basics. Mark will come back personally with an honest first view—not an automated valuation and not a call-centre script.
