Multiply has emerged from stealth with $9.5 million in funding to introduce a new approach to digital advertising-Self-Learning Advertising. The round was led by Mayfield, with participation from Sorenson Capital, alongside notable industry leaders including Max Mullen and Josh Woodward.
Positioning itself as the first AI-native media agency built specifically for B2B organizations, Multiply is tackling a long-standing challenge in digital advertising: performance decay. Traditional campaigns often lose effectiveness soon after launch as creatives become stale and audience engagement drops-a phenomenon the company refers to as “decaying ads.”
Multiply’s Self-Learning Advertising model addresses this issue by continuously optimizing campaigns using internal business data. By leveraging insights from sales conversations, CRM systems, and pipeline outcomes, the platform dynamically refines messaging, targeting, and creative elements-ensuring campaigns improve over time rather than decline.
Early customer results highlight significant business impact. Across its client base, Multiply reports a 300% to 500% increase in sales pipeline generated through advertising. Companies leveraging the platform have also seen improvements in lead quality, campaign velocity, and overall marketing efficiency.

Multiply Co-Founder & CEO Matt Jayson explains that “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.” Today, Multiply focuses on Google Search and LinkedIn advertising, connecting directly to performance data and customer insights to generate high-impact, conversion-driven campaigns.
Founded by Matt Jayson, formerly of Google and Brex, and Ashish Warty, previously SVP of Engineering at HackerOne, the company combines deep technical expertise with hands-on marketing execution. Unlike traditional SaaS platforms, Multiply operates as a hybrid model—blending proprietary AI technology with experienced media strategists to deliver high-speed, high-impact campaign execution.
At the core of Multiply’s platform is a suite of specialized AI agents designed to optimize every aspect of advertising performance. These include a Customer Insights AI Agent that extracts real customer language from sales calls, an ICP Agent that refines targeting based on closed-won deals, and a Quality Score Agent that continuously improves keyword and copy alignment. Additional agents focus on creative design, refreshing visuals regularly, and running hundreds of A/B tests to identify top-performing variations.
Ashish Warty, Co-founder and CTO of Multiply, describes, “Together, these systems allow Multiply to iterate faster than any traditional agency model.”
To ensure quality and compliance, Multiply combines AI automation with human oversight. Campaigns are managed in alignment with brand guidelines and regulatory requirements, allowing businesses to scale efficiently without compromising on brand safety.
“Brand safety is paramount,” explains Warty. “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.”
While the company initially focuses on established channels such as Google and LinkedIn, its infrastructure is designed to support emerging AI-driven advertising ecosystems, including conversational and generative platforms.
“There is a major shift happening in the $50B B2B advertising market,” said Patrick Salyer, Partner at Mayfield and Multiply board member. “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.”
Looking forward, Multiply has plans to grow into a full-fledged omnichannel advertising platform that will allow B2B businesses to manage their campaigns across various channels using a single system. This means that they are poised to be at the forefront of the next generation of AI-fueled innovation in advertising technology.
Having started off on a strong note and having a clear idea of where they are headed, Multiply is revolutionizing the way B2B businesses approach digital advertising, creating campaigns that are not only improving themselves but are doing so as growth engines.
