Vector is a contact-level advertising platform built for B2B marketers. It de-anonymizes website visitors and ad clickers to build precise, signal-driven audiences for campaigns across LinkedIn, Google, and Meta. The platform enables demand gen and ABM teams to target exact buyers by name, reduce wasted ad spend, and prove pipeline impact. Backed by Y Combinator, SignalFire, and HubSpot Ventures, Vector recently launched Vector MCP, an interface that lets marketers query campaign performance and buyer activity in natural language through LLMs like Claude and ChatGPT.
