Vector has raised a $10 million Series A round led by SignalFire and HubSpot Ventures to accelerate development of its AI‑powered ad automation platform for B2B marketers. The company said the funding will support its vision for contact‑level advertising — a model that lets marketers target named buyers based on real intent signals such as website visits, ad clicks, and competitor research.
Alongside the raise, Vector introduced Vector MCP, a new interface that brings its de‑anonymized click‑level performance data into large language models, enabling marketers to query campaign performance and buyer activity in natural language rather than navigating dashboards.
Vector positioned the round as validation of a shift in B2B go‑to‑market strategy, where the teams that win are those that capture early signals before intent becomes obvious. The company said its contact‑level approach transforms anonymous interest into actionable signals and named audiences, enabling marketers to optimize touchpoints in real time based on what is working. With the new funding, Vector plans to expand its AI capabilities so that repetitive tasks are automated while marketers remain in control of strategy, creative, and judgment — the areas where human expertise matters most.
Vector MCP represents the first step toward that future, allowing marketers to ask plain‑language questions about campaigns and buyer behavior and receive immediate answers without switching platforms or waiting for reports. The company emphasized that its goal is not to replace marketers but to compound their impact by giving them better data, faster insights, and the ability to operate at a scale that was previously impossible.
KEY QUOTES:
“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. We see the opportunity to connect all the dots in a buyer’s journey and optimize marketing touch‑points based on what is working.”

“The teams that win in B2B GTM will be the ones who capture the right signals early, before intent is obvious and before a competitor gets there first. Vector has built something new: contact‑level advertising that transforms anonymous interest into actionable signals and named audiences. SignalFire invested because we believe that’s foundational to how modern marketers will build pipeline.”
Varun Ramakrishnan, Principal, SignalFire
“The prevailing narrative right now is that AI will replace your marketing team. We think that’s wrong. The real opportunity is using AI to compound what good marketers already do. We’re not building a product that takes the marketer out of the loop. We’re building one that gives them better data, faster answers, and the ability to operate at a scale that wasn’t possible before.”
Joshua Perk, Co‑Founder and CEO, Vector
If you want a sharper headline, a more GTM‑focused angle, or a version emphasizing the LLM interface, I can shape it however you like.
