Multiply

Multiply is an AI-native media agency built specifically for B2B companies, pairing human paid-media strategists with a fleet of 25+ specialized AI agents to run and continuously optimize LinkedIn and Google Search advertising. Its "Self-Learning Advertising" platform plugs into a company's own data — sales call recordings (e.g. Gong), CRM closed-won outcomes, case studies, website content, competitive kill sheets and product documentation — and runs hundreds of structured ad experiments that refine audiences, copy and creative from real revenue signals. Multiply is a managed service (not a self-serve API product), founded by Matt Jayson (ex-Google, ex-Brex) and Ashish Warty (ex-HackerOne SVP Engineering, ex-Dropbox), and raised $9.5M led by Mayfield in March 2026. It was added to the API Evangelist network as a Mayfield portfolio company; this pass confirmed it publishes no public API, developer documentation, SDK, or well-known discovery surface.

Multiply is profiled on the APIs.io network. Tagged areas include Company, Advertising, Marketing, B2B, and Artificial Intelligence.

Multiply’s developer surface includes pricing and 4 more developer resources.
