Multiply, an AI-native media agency for B2B companies, announced it has raised $9.5 million in funding as it emerged from stealth to launch a new category it calls self-learning advertising.
The funding round was led by Mayfield, with participation from Sorenson Capital and a group of prominent technology executives, including leaders from Google, HubSpot, Braze, Instacart, Brex, and others.
Based in San Francisco, Multiply is positioning itself as a hybrid AI and human media agency that uses proprietary AI systems to continuously improve advertising performance. The company connects directly to sources such as CRM systems, sales call recordings, and ad platform data to extract customer insights and automatically generate and optimize campaigns.
The platform deploys multiple AI agents to handle different aspects of advertising. These include systems for extracting customer language, refining ideal customer profiles, optimizing keyword and copy alignment, refreshing creative assets, and running large-scale A/B testing experiments. The goal is to enable campaigns to improve continuously rather than degrade over time.
Multiply initially focuses on Google Search and LinkedIn advertising, but plans to expand into a full omni-channel ad buying platform. Its roadmap includes broader channel coverage, daily creative refresh cycles, unified cross-channel attribution, and AI-driven budget allocation across platforms.
Early customers have reported significant performance gains. According to the company, businesses using Multiply have seen improvements ranging from 300 to 500 percent in pipeline generation and sales meetings driven by advertising campaigns.
The company was founded by Matt Jayson, formerly of Google and Brex, and Ashish Warty, previously SVP of Engineering at HackerOne and an engineering leader at Dropbox and Airship. Multiply combines AI-driven automation with human strategic oversight from experienced media buyers to ensure brand safety and compliance while maintaining high-speed optimization.
With the new funding, Multiply plans to scale its platform capabilities and expand its reach as new AI-powered advertising channels emerge, including conversational and AI-driven ad formats.
KEY QUOTES:
“Modern companies already have all the data needed to create radically better ads. Sales conversations, CRM systems, and pipeline outcomes reveal exactly why customers buy, yet those insights rarely make their way into ad campaigns fast enough. We help companies get discovered by their dream customers. To do this, we’ve built the world’s most insatiable AI agent. Just like a great growth marketer, it’s never satisfied. There’s never enough pipeline. So it keeps learning, testing, and finding ways to get better.”
Matt Jayson, Co-Founder and CEO, Multiply
“Together, these systems allow Multiply to iterate faster than any traditional agency model. Brand safety is paramount. Every campaign includes human oversight from experienced media buyers, and we work within each customer’s brand and compliance requirements. We move as fast as their teams and systems allow.”
Ashish Warty, Co-Founder and CTO, Multiply
“There is a major shift happening in the $50B B2B advertising market. Service-as-Software is redefining how companies grow, and Multiply has built the first AI model for B2B advertising. Instead of static campaigns managed manually, Multiply has become a compounding growth engine for every company it partners with.”
