Frequently asked

How was this list built?
It starts with my own reading list from about 15 years in B2B sales and product. I removed duplicates, assigned every book a topic and added the standard works that were missing.
What does the rating mean?
It shows practical value for B2B go-to-market, not literary quality. A classic can be great and still score low because it changes nothing in your week.
Why is there criticism on every book?
Because no book fits everyone. The criticism summarises what readers and reviewers flag repeatedly: dated examples, thin evidence, too much self-promotion.
Where should I start?
Three books: Obviously Awesome for positioning, Gap Selling for discovery and The Mom Test for the customer conversations before both. That covers most of the mistakes I see in B2B teams.
The next step

A tool is not a system.

The most common mistake after product-market fit: buying tools and hoping for scale. What is missing is the shared context behind them: product knows one part, sales another, every agent starts from zero. I call the answer Get Multiplayer: Humans set goals, decide and approve. Agents prepare and do the repeatable work. Shared goals and shared context keep them working together.
