Laurence is a New York City based Y Combinator (Winter 2026) company that automates Amazon advertising and marketplace management for brands. The platform applies quantitative-trading methodology — hierarchical Bayesian bid optimization over Amazon Marketing Stream data landed in ClickHouse — to maximize contribution margin after margin and ad spend rather than optimizing to rules-of-thumb ACOS targets. Laurence ingests Amazon Advertising and Seller Central data, prices every keyword auction, and exposes the resulting data to customers through Ask Laurence and a hosted, OAuth-protected Model Context Protocol server that brings Amazon Ads data into Claude Code, Cursor, and Codex. The company raised a $5.8M seed round led by Susa Ventures and Box Group with participation from Y Combinator.
