Paul de Metter

Founder and Collector at Walkouts
I started Walkouts because I wanted to bring collectors the same confidence I expect when I add a shirt to my own collection. I’ve been around football all my life, as a father, a coach, a fan, and a collector, and I know how important it is that every shirt tells a real story. At Walkouts I focus on sourcing authentic pieces, proving their provenance, and sharing the details that give collectors peace of mind. My background in technology and business helps me combine precision with passion, making Walkouts a place where credibility matters more than hype.
My work revolves around authentication, provenance and grading, with a sharp eye on the details that separate genuine signed shirts from the rest. I work with trusted certification partners such as Beckett, Fabricks NFC and ICONS, and I build our processes around transparency and clear proof. Whether it’s organising signing sessions, verifying certifications or guiding collectors on what to look for, I bring years of hands-on experience in the signed football shirt market.
