James He is Co-Founder and CEO at Artificial Societies, an AI platform that simulates human societies to predict behavior and social dynamics. The company serves clients including Anthropic and 11x, helping them test marketing and content before real-world launch.

James earned First Class Honours in Behavioral Sciences from Cambridge and worked as the first machine learning scientist at Yonder Credit Card, building their entire lending ML systems. He left rural China at age 14 and turned down a PhD offer to pursue startups.

James led one of the largest studies of an LLM society in Europe, published in the British Journal of Psychology, involving 33,000 AI chatbots. At age 21, he started his own scholarship and at 16 was offered $600k for an ed-tech startup but chose Cambridge instead.

Artificial Societies raised $5.85M in seed funding led by Point72 Ventures and is part of Y Combinator W25. The platform achieves over 80% accuracy in predicting social media performance, compared to 17% for ChatGPT.

Over 3,000 startup founders have run investor simulations using Artificial Societies' Wave product. The company's platform features over 500,000 AI personas and enables users to test content with target audiences in minutes rather than weeks.
