Why we make it
Written analysis has its limits. Some ideas are easier to explore in conversation — especially when the person building something can walk you through their thinking in their own words. The SIGNAL Podcast is where we do that work.
We record remotely, edit lightly, and publish weekly. No ads, no sponsor reads, no affiliate pitches. If you like the newsletter, you'll probably like the podcast.
