What if you could simulate human reactions — and know exactly how your customers, investors, or audience will respond before you act? James He is building precisely that with Artificial Societies.
In this episode, we dive deep with James, YC W25 founder of Artificial Societies — a wildly ambitious startup that simulates entire groups of humans using AI personas to predict how messages spread, markets react, and products succeed (or fail). From simulating 1,000 VCs to get into YC… to replacing $20,000 market research surveys, this conversation is a masterclass in founder execution, behavioral science, and AI-first GTM strategy.
What you’ll learn:
• How Artificial Societies works (and how founders are really using it today)
• Why traditional A/B testing and market research are broken
• Product-led growth lessons from 15,000+ activated users
• The surprising YC tricks James used to get into the batch
• Practical ways AI can upgrade your messaging, GTM, and PMF search
• The future of simulating entire economies (and why we’re not there yet)
