Multiply Raises $9.5M in Seed Funding to Build AI Media Agency for B2B Enterprises

Most ad budgets don’t die loudly. They fade out. Quiet decay. Campaigns lose edge, messaging drifts, and the only thing compounding is wasted spend. Multiply looked at that slow bleed and decided to turn it into signal. $9.5M in seed funding. Led by Mayfield, with Sorenson Capital in the mix, plus sharp money from Max Mullen and Josh Woodward, alongside operators from HubSpot, Braze, Issuu, Brex, Sierra, and Common Room. That’s not tourist capital. That’s “we’ve built, broken, and scaled this before” capital.

Matt Jayson and Ashish Warty are not guessing here. Matt Jayson spent time at Google and Brex understanding how acquisition actually behaves when money is on the line. Ashish Warty comes out of HackerOne, Dropbox, Airship. Systems, scale, pressure. CEO and CTO who speak both revenue and infrastructure fluently, which is rarer than people admit.

Multiply calls itself an AI media agency. Cute label. What it really does is wire your ads directly into reality. Sales calls, CRM data, closed won signals. The stuff most companies say is “super valuable” and then proceed to ignore when launching their next campaign.

Their AI agents do the heavy lifting. Customer Insights Agent pulls language straight from the mouths of buyers. ICP Agent sharpens targeting based on actual wins. Quality Score Agent tunes the mechanics. Creative Design Agent keeps things fresh weekly. A/B Testing Agent runs enough experiments to make your last agency look like they were guessing with vibes.

And the numbers land like they’ve been audited by gravity. 300%–500% lift in pipeline and meetings. Vanta clocks in at 770% more sales meetings. That’s not incremental. That’s what happens when feedback loops finally close.

Here’s the uncomfortable truth most teams dance around. Ads don’t fail because platforms are broken. They fail because the business intelligence never makes it back into the system fast enough. By the time insights travel from sales to marketing, the campaign is already cold.

Multiply shortens that distance to near zero. For B2B companies living inside Google Search and LinkedIn, this is less about better ads and more about finally making ads behave like a living system instead of a quarterly experiment.
