Multiply Technology, AI Advertising Platform, Raises $9.5 Million in Funding

Multiply Technology recently raised $9.5 million (approximately 1.368 billion KRW) in funding and launched an AI-powered advertising platform with self-learning capabilities. The company states that this technology analyzes internal enterprise data through artificial intelligence to achieve continuous self-optimization, aiming to solve the problem of “ad fatigue.” Over time, fixed advertisements tend to lose their appeal to audiences, and the platform is attempting to address this challenge.

The funding round was led by Mayfield, with participants including Sorenson Capital, Max Maren, co-founder of Instacart, Josh Woodward, head of Google’s Gemini division, and executives from HubSpot, Braze, Brex, and other companies.

Multiply was co-founded by Matt Janson, CEO of AI financial company Brex and former Google executive, and Ashish Valsy, CTO who previously led engineering teams at HackerOne and Dropbox. The company develops personalized ads through customer insights AI agents that utilize real customer language and data, delivering innovative creative messages that highlight why customers choose this company over competitors.

The company’s approach involves continuous optimization of target audiences, ad copy, and design through hundreds of structured experiments. Valsy emphasizes, “These systems enable Multiply to iterate at a pace beyond any traditional agency model.” Every ad is manually verified before release to ensure brand safety and maintain clear management of design and thematic compliance.

Although Multiply started with Google and LinkedIn advertising, it is now preparing to collaborate with emerging AI ad platforms like ChatGPT. Recently, OpenAI piloted ad placements within ChatGPT for U.S. users, with a minimum participation cost of $200,000 (about 288 million KRW). Multiply is working to build a comprehensive cross-channel platform to optimize advertising across all major platforms.
