In this episode of Property-Porn Stars, host David Lindley speaks with Mark Breffit, a leading figure in London’s premium property market.

With over £1 billion of property sold, Mark shares his journey from working at Dexters, Knight Frank, and Hamptons Private Office in prime central London, to launching his latest venture — KnokKnok, a prop-tech platform aiming to reshape how buyers and agents connect.

We cover:
•Life inside corporate agency vs the independent mindset
•Mark’s early career experience with Airbnb and what he learned about innovation
•Why tech, personal branding, and consumer behaviour are reshaping estate agency
•The inspiration behind KnockKnock, and how it bridges the gap between portals, social media, and direct client connections

If you’re interested in property, startups, or the future of estate agency, this is a must-watch conversation.
