London-based Artificial Societies, which was part of Y Combinator's Winter 2025 batch, has secured $5.35 million in seed funding.

The startup, which launched in 2024, has developed a platform that generates AI personas that help companies test how their product, marketing, branding, and other content might be perceived.

"We primarily use AI agents that chat with each other, mimicking how real humans influence each other," cofounder and CEO James He told Business Insider. "We try to capture that artificial society, and how it will respond to any input. It can be a marketing message or a product proposition, and we produce analysis for our customers."
