Closed-Loop Revolution

Why CRM systems document errors instead of preventing them — and what a closed loop in sales looks like.

Book cover Closed-Loop Revolution by Matthias Maier and Christopher Gansert

The diagnosis

Which errors arise in sales, and why none of them ever show up as a warning in the CRM.

The mechanics

How an open loop becomes a closed one: detect, analyse, activate, neutralise.

In practice

What changes day to day when corrections arrive where they are actually needed.

Matthias Maier & Christopher Gansert, 2026
