Multiply, an AI media agency building self-learning ads for B2B companies, raised a $9.5 million seed round, CEO Matt Jayson tells Axios exclusively.

The big picture: B2B marketers are under increased pressure to prove marketing ROI in real time.

Follow the money: Mayfield led, joined by Sorenson Capital, Instacart co-founder Max Mullen, Google's Josh Woodward and other executives.

How it works: Multiply connects directly to a company's sales calls, CRM data and customer communications to learn why buyers convert. It uses that data to continuously generate and improve ads across platforms like Google and LinkedIn. 

Jayson says the platform can automatically turn customer feedback and quotes into ads. 

What they're saying: "Creativity is getting stale faster than ever," Jayson says. "Promotional photos or videos are getting ignored within weeks, not months."

Zoom out: More than 90% of B2B buyers say they plan to use generative AI in at least one area of a future purchase, according to Forrester data.

Multiply is betting that advertising will need to become more adaptive as AI shapes how buyers discover and evaluate products.

What's next: Multiply plans to use the new funding to hire more engineers and growth strategists, as well as expand to platforms like Meta and Reddit.
