You're in.

The Prelude and Chapter 1 are below — and on their way to your inbox too.

Thank you for wanting to read this before it’s out in the world. The 90% Code launches in October 2026, and you’ll hear from me as that get closer - including when the full canvases are released free.

If you know someone who’d find the Field Guide (core thesis and frameworks preview) useful, it’s made to be passed along: the90code.com.

Best,

Sonali Sharma (she/her)
