The Craft of Growth

Abstract

This book is for founders and operators who want a metrics driven company without busywork. You will learn the core SaaS metrics, how to calculate them correctly, and how to set targets that match your stage. We cover the full loop: ask better questions, generate the right views, read the results, and decide what to do next. Part II brings it to life with case studies from Supabase, Replit, and ElevenLabs.

This book walks through:

• The core metrics and formulas you need: LTV, MAU, CAC payback, NRR, activation, retention
• Stage based benchmarks and what "good" looks like at Seed, Series A, and beyond
• A simple operating rhythm: scorecards, owners, cadences, and decision reviews
• How to write prompts for metrics that get the exact chart, table, or SQL you want
