The Confidential Information Memorandum (CIM)
The detailed information package, given only after a buyer signs an NDA, whose job is to tell the story of the business well enough to draw out a first offer.
What the CIM Is
The Confidential Information Memorandum (also called the CIP, the deal book, or simply "the book") is the document a seller and intermediary prepare to describe a business in enough depth that a vetted buyer can decide whether to pursue it and at what price. It sits at a specific point in the sale sequence: after a buyer has been screened and has signed an NDA, but before any letter of intent. Warrillow defines it as the document that gives "an acquirer enough information to decide whether or not they want to pursue acquiring your company." Burlingham, using the same term, calls it the "marketing document laying out a company's history, finances, and growth potential for buyers."
The CIM follows the teaser. Where the teaser is a one-page anonymous summary whose only job is to earn an NDA, the CIM is the full reveal that comes once confidentiality is in place.
What Goes In It
A CIM typically covers company history, the products or services, the team, the financials, and the growth opportunity. McDannell treats the CIM as one component of the broader data room, "a hefty document detailing the business," common for larger deals and optional but often requested for smaller ones. For sub-$1M deals she frames it as one organized folder among P&Ls, balance sheets, FAQs, owner duties, org chart, and stats.
Warrillow's stance is that the CIM is a marketing document, not an accounting exercise. It should sell the job the company gets done for the acquirer, features and benefits, not just the numbers.
"People don't want to buy a quarter-inch drill. They want a quarter-inch hole!"
Warrillow, The Art of Selling Your Business, ch. 10 (quoting Theodore Levitt)
The Risk of Getting Naked
Warrillow titles his CIM chapter "Getting (Almost) Naked" for a reason: the document forces you to disclose real detail to people who may not be sincere buyers. Some parties sign NDAs only to harvest proprietary information. His examples include Viviscal's hidden formula and the ebookers commission-rate leak. The lesson is to hold back the true crown jewels until later, even inside a signed-NDA disclosure.
This connects to his larger thesis that information is currency and should be spent deliberately.
"Information about your company is a form of currency, and as with money, you need to decide how to spend it."
Warrillow, The Art of Selling Your Business, ch. 4
McDannell reinforces the same discipline from the small-deal side: never share financials before a phone call and a signed NDA, and withhold vendor and customer names until late in the process.
"Every piece of information that you have here is going to attract or repel specific buyers."
McDannell, Get Acquired, ch. 4
Why It Matters
The CIM is where the buyer forms their first view of price. A well-built one frames the business as a category leader and an attractive future cash flow stream, which supports a stronger initial offer and a faster process. A thin or sloppy one invites doubt, slower diligence, and a lower starting number. Burlingham's research is blunt about the stakes of sellability overall: only about 20% of businesses listed actually sell, so the materials that introduce a company to buyers carry real weight.
