Priya, founder of a subscription-based snack brand

I'm not technical. I don't get excited about data models or API architectures. But this book isn't really about those things — it's about understanding why customers say yes or no, and how to arrange your business so they're more likely to say yes without feeling manipulated. It's practical in a way that surprised me. I read the chapter on silent churn (people who just drift away) and realized I'd been ignoring half my customer base. I made one change — a small, unexpected gift for inactive subscribers — and re-engaged people I thought were gone forever. The book paid for itself in a week.
