James He

Time to spill some facts about James He – this dude’s the real deal in the startup world. He’s a total brainiac who’s jumped into some heavy stuff with AI and social dynamics. So, James is the co-founder and CEO of Artificial Societies, a fresh startup that just crushed it in YC’s W25 batch. Basically, they’re building these crazy AI-powered simulations of big groups of people – like, how they respond, influence, and react to info. Think of it as a way to see into the future of social behavior, but way smarter than anything we’ve seen.

Before all this, James was already deep in the game. He’s got serious chops in machine learning, social network analysis, and predictive modeling – he’s been doing data analysis since way back, even publishin’ papers and grinding in academia. He worked at Yonder doing ML and data science, hit up Cambridge as a data analyst, and even spent time at the MRC Biostatistics Unit. So, he’s not just some guy with ideas – he’s actually built his skill set in the trenches.

He’s a Cambridge grad, no surprise – that’s where he got his BA. But what’s wild is how he took all that academic and technical background and turned it into something super practical and original. In 2024, he co-founded Artificial Societies, and they rolled into YC’s Winter 2025 batch – like, the top of the top for startups. Their first product, Reach, is pretty sick – it simulates LinkedIn audiences so you can test your posts before dropping them live. Basically, he’s trying to crack how influence actually works at scale, and how people respond online.

He’s based in London, which is quickly becoming a hub for this kind of modern stuff. And honestly, looking at his process, what stands out is his relentless curiosity and drive to use AI to understand social behavior on a massive scale. Like, he’s not just playing with tech for the sake of it; he’s trying to solve real problems about influence, communication, and maybe even how societies function.

This guy’s story is about someone who took his academic smarts, jumped into startups, and then said, “Nah, let’s go bigger.” He’s motivated by understanding the complex, messy ways humans influence each other – and he’s building tools that could change how we think about social media, marketing, or even politics. No cap, James He is on a mission to decode the social fabric with AI, and that’s why he’s someone you gotta keep an eye on.
