Funding Market: a16z Leads Highstock's $30M Series A for AI Overstock Marketplace
Andreessen Horowitz (a16z) announced it is leading a $30 million Series A funding round for Highstock, an AI-powered B2B marketplace that connects brands with excess inventory to a vetted network of global wholesale buyers. Highstock aims to provide a brand-safe alternative to traditional liquidation channels, helping brands discreetly offload overstock while preserving brand equity. The platform handles matching, logistics, compliance, and payments. Founded by CEO Camille van Horne and CTO Sean Cashin, both former Instacart employees, Highstock has over $1 billion in inventory listed, works with over 100 major brands, and has kept over 10 million pounds of product out of landfills. The company is initially focused on beauty and personal care, with apparel launching now. a16z partner Olivia is joining the board, and Jeff Jordan is participating as an advisor.
Highstock's $30M Series A and AI-native B2B marketplace addresses a niche but significant problem for consumer brands, with potential impact on retail media and commerce, but it is not industry-shifting for AdTech.
