What is the MQL Collapse?

The MQL Collapse is the name the book gives to what went wrong inside the marketing-qualified lead. An MQL became one bucket holding four different things. Account fit: is this even the kind of company we sell to? Contact relevance: is this the right person inside it? Engagement: has this person touched our marketing? Buying readiness: is something happening inside this account right now that makes them open to a conversation? Four questions, four realities, mixed into one score and thrown over the wall. The most expensive confusion in B2B is treating two of them, brand awareness and buying readiness, as a single axis, because the two have to be managed differently: you build awareness with content and repetition, and you cannot build readiness, only see it sooner.

The collapse was not stupidity. When SiriusDecisions introduced the Demand Waterfall in 2006, data was thin, enrichment slow and expensive, and behavioral signals hard to capture, so teams compressed several questions into one stage because keeping them apart was more than the tooling could bear. The constraints went away; the habit outlived them. Its cost is the three conversations that open the book: a CMO whose team was spamming people who weren't ready, a VP of Sales rejecting leads that looked qualified on paper and felt cold in the room, and a marketing director who did not know who she was allowed to target.

The Demand Compass is the un-collapse: it puts awareness and readiness on two separate axes and scores accounts, not people, with an audit trail. The MQL still works in the narrow case it was built for, a single identifiable buyer, a short cycle, and a channel where intent shows up on a form.
