D.LOUISE was founded in 2021 by Olivia Jenkins, who named the brand in tribute to her late mother, Deborah Louise. Co-founded with serial entrepreneur Jack Zambakides and former professional cricketer Oliver Smithson, the South London-based company has quickly become known for its waterproof pieces crafted from stainless steel, that are designed to withstand daily wear without tarnishing. The brand has attracted a loyal following, amassing over 230k Instagram followers, and has received investment from Steve Hewitt, former chief executive of Gymshark, to help facilitate the brand’s international expansion. Olivia has focused on brand story-telling and a social media content to help grow the brand to £8.6m in 2025.
