About this site

Hi, I’m James. I study breakthrough moments in emerging tech and how they change the way value gets created and moved around in the digital economy.

Every week I publish my 3×3, an ultra-concise briefing on the most important stories in tech, markets, and academic research, alongside longer notes that explore the innovations behind technological and economic progress. I call this project Line Break because I’m interested in the moments when everything suddenly opens up — breakthroughs, step changes, and new possibilities.

If you’re curious about how cutting-edge ideas turn into real-world impact, this might be for you.

About me

I’m the Head of AI at STAC, where I evaluate bleeding-edge technology for global financial institutions, and a former exec at KX, the trading technology used by the biggest firms on Wall Street.
