Highstock runs an AI-powered B2B marketplace where consumer brands sell surplus and short-dated inventory to a vetted network of global wholesale buyers, including retailers and live-commerce sellers on channels such as Whatnot and TikTok Live. Founded by former Instacart product director Camille van Horne and CTO Sean Cashin, the New York-based company started in beauty and personal care, lists more than $1 billion in inventory from over 100 major brands, and handles matching, logistics, compliance and payments so brands can clear excess stock discreetly without fire-sale optics. Its beachhead is beauty and personal care, with expansion into apparel and fashion underway.
