I built a 200,000-page product with agents in months, then spent longer learning to run it.
Some of it works better than anything I have shipped alone. Some of it published my database, and one caching flag nobody checked cost $208 a month. I write about both, with the numbers attached.

What I run
- Riffiter
- Rate albums out of five, log what you actually listened to, and find records through people whose taste you already trust. Letterboxd, for music.
- Tuval
- Pages, databases and an infinite canvas over one set of records. Local-first, CRDT.
- Gist
- Follow buy, sell and hold calls on crypto and stocks in one place.
- Friemind
- Leave a post-it on a friend's wall, fill an intention jar, send letters to open later.
