  • Why you should build some fake AI products
    Feb 10 2026

    I prototyped a full video podcasting app in a couple of days using Claude Code, and it's completely changed how I think about building new features for Transistor (the podcast hosting product I co-founded).

  • These are the voice memos I sent to Adam Wathan last night
    Nov 28 2025

    My friend Adam Wathan has a new podcast called Adam's Morning Walk, and in the last episode he talked about how he's thinking about building with AI:

    How can someone sit in front of a text area and explain what they want in enough detail that the AI is gonna produce something good?

    I was listening to this episode last night and it brought up all sorts of thoughts for me. So I opened up telegram and sent him a series of (slightly inebriated) voice memos.

    I'm publishing these here in case they spark some thoughts/ideas for you as well.

    F-stop example

    If you have a response, let me know!

  • How high is customer demand?
    Nov 26 2025

    Successful startups don't create demand. They position themselves in the path of existing demand.

    In a good market, customers provide their own motivation.

    Your job isn't to create customer motivation; it's to find where it already exists and then build something that satisfies it.

    00:00 I was listening to the Offsite podcast.

    00:46 How high is the customer's desire for the product?
    01:23 When will a customer buy even when there's friction?
    01:59 The pitfalls of optimizing a product when there's no demand
    02:45 A framework for assessing Market Demand
    03:21 Conclusion
