For product leaders who measure platform quality by what their customers actually feel.

Feature breadth is easy to count. Cohesion is what your customers experience, and it is where most platforms underinvest because it is hard to put on a roadmap. This book makes the case that cohesion, not breadth, is the measure that matters.

It names the five places infrastructure leaks into a product (handoffs, sign-ins, errors, status, partner branding), sets out the principles of invisible integration, and gives you an audit to run on your own surface. It closes with how ECGrid is built to disappear inside your product.
