Artificial Societies

I've been studying societies for my entire adult life. At Cambridge, I found a love in combining technology and humanity to ask: Can computers predict individual and collective human behaviours? I am fortunate to be now working on this life-long passion full time, as the co-founder and CEO of Artificial Societies.

What do we do at Artificial Societies?

We simulate societies. If you have a target audience, we will build you a simulation where you can test how your ideas will land - like your messages, product propositions, or even policies - before you launch them into the real world. Our mission is to scale collective innovation. Our vision is a world where every product, policy, or message is developed and tested in Artificial Societies, before being launched into the real world.

While Artificial Societies is not a research group, I am fortunate to have continued academic work with my mentors in my spare time, now collaborating with researchers from Oxbridge, NYU, and UCL. Together, we research on the potentials and limitations of LLM-based artificial societies, the topologies and dynamics of online communities, and how we might find ways to maintain open debates while bridging social divisions.

Bridging Disciplines

When I got my first paycheque (thanks Yonder), I pledged to donate 10% of my disposable income to support interdisciplinary explorations:

The James K. He Scholarship is dedicated to support data-driven, interdisciplinary research at the undergraduate level. Open to students of ALL subjects at Selwyn College Cambridge, with Preference given to projects from disciplines with limited fundings.

Why did a 21-year-old set up a scholarship?

In most of human history, innovators are those who love building bridges, those who refused to be defined by a single way of thinking. Sadly, there is hardly any funding in the UK that supports innovative, cross-discipline research, especially for undergrads.

So, I decided to put money where it counts - I've enjoyed the self-sovereignty of not being defined by a single discipline, and I hope to build a community of innovators who refuse to be defined.

Wow, thanks for reading this far!

You should get in touch.
