A mentor of mine closed on a business off a 47-page CIM showing 22% YoY growth. Eighteen months later he was unwinding it. The tell was in the document the whole time. The CIM said customer concentration was "approximately 30% from top 3 clients." Diligence showed 41% — and one of the three was already out running an RFP with a competitor. His takeaway, which I've adopted for every deal we screen: sellers mostly don't lie. But CIMs are written by people paid to surface the best version of the business. Your read has to run in the opposite direction. He calls it the Inverse Read. Four rules: 1. Executive summary last, not first. It's an anchoring device. Start with the financials and customer data, then let the narrative confirm or contradict what the numbers already told you. 2. Circle every "approximately," "roughly," and "around." In a CIM, softened language almost always marks a number that couldn't survive precision. Make each one a specific diligence request. 3. Map growth years against the market. A 31% year deserves the question: organic, or did a competitor exit / a one-time contract land? The CIM won't answer it. Industry research will. 4. Hunt what's absent. No churn discussion in a SaaS CIM. No key-person language in a professional services firm. No mention of customer contracts in a business built on them. Silence is a data point — write down what a candid version of this document would have included, and ask for it. Across the deals we've screened, the pattern holds: post-close failures almost always had the warning sitting in the CIM. It just got read optimistically the first time, because the optimistic read builds momentum and gets you to the next stage faster. Speed toward the wrong deal isn't efficiency. It's the most expensive thing in this business. Searchers — what's the most revealing thing you've found buried in a CIM (or conspicuously missing from one)? Genuinely want to hear the patterns you're catching. 👇
