Questions

Common questions.

  1. What is The AI Economy?

    A newsletter covering consumer and enterprise AI, platform strategy, and the companies reshaping how work gets done. Reported, not aggregated — written by a technology journalist who has covered the space since before generative AI was a mainstream phrase.

  2. How often does it publish?

    Enough to keep you ahead, never enough to clutter your inbox. You'll also get first-look coverage and original interviews whenever the story is worth your time—which, lately, is often. Nothing filler-grade goes out under this masthead. A weekly roundup is delivered Fridays on LinkedIn.

  3. Is it free?

    Yes. Every issue is free. Subscribe on Substack and it arrives in your inbox. No paywall, no premium tier. If that changes, subscribers will be notified well in advance.

  4. How is this different from other AI newsletters?

    The AI Economy explores the people building AI and the reasons behind what they build. I'm interested in how enterprise teams are actually deploying AI, where the editorial and operational models are breaking down, and what platform-level shifts mean for practitioners making decisions this quarter. It is written for people doing the work, not watching it from the outside. My goal is to not focus just on what's being announced, but why it exists and why we should care. The stories are what you'd expect to read on Inc. and First Round Review or see on "60 Minutes."

  5. Can we pitch you stories?

    Yes, I do accept embargoed news and exclusives. Please reach out with your announcements, launches, and story ideas—email me or use this form. I also accept tips securely via Signal at @kenyeung.888.

  6. Where can I read past issues?

    The full archive is listed above on this page. All issues are also available on Substack. The plan is to host the canonical archive here on thelettertwo.com as the publication grows — independent of any platform.

  7. Can I republish or cite content from the newsletter?

    Yes, with attribution. Short excerpts with a link back to the original issue are fine. For longer republication or syndication, reach out via LinkedIn.
