Vector Gets $10M Series A to Power Contact-Level Ad Targeting

Vector raises funding from SignalFire and HubSpot Ventures for an AI tool that lets marketers ask questions about ad performance.

Vector, a Boston-based contact-level advertising platform for B2B marketers, raised $10 million in Series A funding on May 13, led by SignalFire and HubSpot Ventures. The company will use the capital to expand AI automation tools and launch Vector MCP. It is a natural-language interface that connects de-anonymized ad click data with large language models, including Claude and ChatGPT. 

Vector’s platform identifies specific buyers engaging with ads by connecting intent signals, website visits, ad clicks, and competitor research to named contacts. The approach targets a persistent gap in B2B advertising, where most targeting relies on broad firmographic filters rather than individual-level engagement data.

The Series A follows growing demand among demand generation and account-based marketing teams for attribution tied to pipeline creation, not anonymous traffic metrics. 

Vector MCP, launching alongside the raise, allows marketers to ask plain-language questions about campaign performance and receive answers without switching between reporting platforms.

Every marketer we talk to is trying to do more with the same budget and prove it’s working. Vector gives them something that hasn’t existed before: the ability to target specific buyers based on real intent signals in real time.
Adam Coccari, Managing Director at HubSpot Ventures.

Vector co-founder and CEO Joshua Perk pushed back against the broader industry narrative that AI tools displace marketing headcount. The company said its roadmap includes expanded automation workflows, audience creation features, and deeper integrations with tools marketers already use. 

The raise positions Vector against established account-based marketing and intent platforms, including 6sense, Demandbase, and RollWorks. The company’s path to a defensible market position likely depends on the quality of identity resolution and the degree to which Vector MCP can execute workflow changes, not merely surface insights.

The move comes as B2B marketing budgets face greater scrutiny and demand generation teams are under increasing pressure to link ad spend directly to pipeline and revenue outcomes.
