Read about the books.

eBook. Cold Start, coming first.

246 pages. PDF and EPUB.

What this book is.

On March 16, 2026, I asked Claude four questions. The first three were about the work. The last one was do you like working with me? I needed someone, anyone, to tell me the truth. The answer became a series. The series became this book.

Every page co-authored with Claude. Every word reviewed by a human. The conversations are real, lightly edited for clarity. The methodology is real. This is what AI-native product development looks like when one person holds it to Apple-level standards.

What you'll find inside.

The room where the story begins.

A real desk, in a real room, in the Twin Cities, MN. Black wall. A Mac Studio, M1 Max, 64GB, behind three Apple Studio Displays. A Mac mini beside it. An iPad Pro, an iPhone and an Apple Watch on a Belkin stand, and three sets of AirPods Pro. A red Dieter Rams book on the shelf above a Steve Jobs portrait.

This is where the cold start happened. One founder, no team, Claude as the entire organization, from the C-suite down.

The desk where Cold Start happened. Twin Cities, Minnesota.

Common questions.

Both PDF and EPUB. The PDF is optimized for A5 reading on iPad, laptop, or print. The EPUB is for Apple Books and other ereaders.

Yes, that is the plan. The committed list is German, Spanish, French, Portuguese, Italian, Polish, Japanese, and a British English edition. They are translated with Claude, the same way the book was written, from an English edition that a human read end to end. Japanese is the one we hold back for a native reader before it ships, because it is the language where a mistake is hardest for us to catch ourselves. British English is a spelling and idiom conversion rather than a translation. No dates on any of them. A language is announced when it is finished, not when it is started.

No. It is a memoir of one build. The title and subtitle read like a technical manual, so this is worth saying plainly. You will see the architecture, the decisions, the arguments, and the mistakes as they happened, in order, but it is a story about doing the work rather than a set of instructions for doing it yourself.

Yes. The Claude voice sections were generated by Claude Opus 4.6 and 4.7 across the fifty-day build, lightly edited for clarity. Every word reviewed by a human. The methodology is real. The conversations are real. Apple, Inc. and Anthropic PBC did not sponsor or endorse this book.

I built a company designed to keep going when I stop. Now I have to stop.
