N°03 · About the founder
Guilherme Ribeiro, Founder
Guilherme founded JULL to do one thing properly: deal in Hermès, and nothing else. He inspects every piece the house sells by hand — hardware engraving, blind stamps, stitch density, leather grain — and speaks to clients personally from first enquiry to final handover. His market commentary comes from live transactions in the company’s Knightsbridge stock room rather than from published indices, which is why it often runs ahead of the auction record books.
