About

Sources is a newsletter about the AI race, featuring original analysis and exclusive interviews. Issues are published two to three times a week, with occasional issues made available to free subscribers.

My name is Alex Heath. I started Sources in September 2025 and have broken agenda-setting scoops and interviewed many of tech’s top leaders, including Mark Zuckerberg, Demis Hassabis, Sam Altman, Daniel Ek, and more.

I’ve been covering the tech industry for over a decade at The Verge, The Information, and Business Insider. My work has been featured in dozens of other publications, including The New York Times, CNN, The Wall Street Journal, CNBC, Bloomberg News, TIME, New York Magazine, and MIT Review. Stories I’ve written have also been cited in congressional hearings, high-profile lawsuits, and on Saturday Night Live. I’ve appeared onstage at SXSW, Web Summit, the Code Conference, and HumanX, and won multiple awards from the Society of American Business Editors and Writers.

Aside from the Sources newsletter and podcast, you can find me online on X, LinkedIn, Threads, and Instagram.
