Kourtney Kardashian — Poosh & Lemme

Kourtney Kardashian turned Poosh and Lemme into a $30 million-plus business in Lemme's first year, with her gummy vitamins selling out in 48 hours. Products like "Lemme Chill" (ashwagandha) and "Lemme Focus" (B12) target the GLP-1 trend without clinical backing, yet revenue outpaces the average celebrity wellness startup by 40%. Compared to Alex Jones's InfoWars (#5), which relied on conspiracy-driven sales, Lemme's appeal is affordable aspiration - a $30 bottle for a Kardashian glow. This is not evidence-based medicine, but it's a $30M lesson in branding to women who trust celebrity, outperforming #7 Kate Hudson's Fabletics in per-product profitability while staying far less controversial.
