Vector has raised $10 million in Series A funding led by SignalFire and HubSpot Ventures, announced in a press release. The company plans to use the funds to advance its AI advertising automation platform for business-to-business marketers.

Alongside the funding, Vector introduced Vector MCP, an interface that connects its contact-level advertising data with large language models such as Claude and ChatGPT. The feature allows marketers to query campaign performance and buyer activity using natural language instead of traditional dashboards.

Vector’s platform helps demand generation and account-based marketing teams target named buyers based on intent signals like website visits, ad clicks, and competitor research. The company aims to enable marketers to identify and act on early intent signals to improve campaign precision and reduce wasted ad spend.

According to the announcement, the new funding will support further development of tools that automate repetitive advertising tasks while allowing marketers to focus on strategic and creative work.
