What is a confidential information memorandum?
A confidential information memorandum, or CIM, is the central sales document of a company sale. Buyers receive the CIM only after signing an NDA, and only after the anonymous one-page teaser has made them ask for more.
A CIM is not marketing copy. Every number and claim in the document becomes a diligence assertion that the buyer’s team will later test against the data room, and a claim that fails costs the seller price or credibility.
Windsor Drake writes every CIM so that each sentence can still be defended eight months later at closing. That discipline is what separates a CIM from a pitch deck.
What sections does a CIM contain, and what does a buyer do with each?
A Windsor Drake CIM follows a standard chapter sequence: executive summary, company overview, market, products, customers and revenue quality, financials and adjustments, organization, growth plan. Each chapter exists because a specific buyer question must be answered before an indication of interest can be priced.
| CIM section | Purpose | What the buyer tests | Common seller error |
|---|---|---|---|
| Executive summary | State the investment thesis in two pages | Whether the story matches the numbers that follow | Adjectives where figures should be |
| Company overview | Explain what the business does and how it earns revenue | Whether the model is understandable in one read | Founder history that buries the business model |
| Market | Size the opportunity the buyer is purchasing | Whether growth claims rest on a reachable market | Giant TAM figures with no connection to actual revenue |
| Products | Show what customers pay for and why they stay | Switching costs and technical durability | Feature lists instead of retention logic |
| Customers and revenue quality | Show retention and recurring mix without naming accounts | Concentration and churn against the stated retention | Hiding concentration that diligence will surface anyway |
| Financials and adjustments | Present three years of history plus adjusted EBITDA with itemized add-backs | Whether add-backs survive a quality of earnings review | Aggressive add-backs that die in QoE |
| Organization | Show the company runs without the founder | Key-person dependence | An org chart where every line reports to the founder, presented with no succession answer |
| Growth plan | Give the buyer credible upside beyond current results | The bridge from historical numbers to the forecast | Hockey-stick projections with no bridge from current performance |
The financials chapter carries the most weight. Adjusted EBITDA with itemized add-backs sets the baseline that a quality of earnings review, typically $40,000 to $100,000 of spend, will later confirm or destroy.
What does not go in a CIM?
Customer names never appear in a CIM. Customers are labeled by rank and category, such as Customer A, a top-ten regional insurer, because NDAs are signed by competitors and NDAs get breached in practice.
Exact per-customer pricing stays out for the same reason. A competitor that learns the company’s pricing floor can use it in the market whether or not the deal closes.
Any claim the company cannot support with documents stays out. Everything in the CIM becomes a diligence assertion, and a buyer that catches one unsupportable claim will re-test every other claim with a discount already in mind.
Source code, employee-level compensation, and contract-by-contract terms belong in the staged data room rather than the CIM. Detail a buyer needs eventually is released by phase, matched to the buyer’s demonstrated commitment.
How long is a CIM, and when is it written?
A CIM for a lower-middle-market software company typically runs 25 to 50 pages. Shorter documents underserve the financial chapters, while longer documents signal that the advisor could not decide what matters.
Windsor Drake drafts the CIM during the 8 to 12 week preparation phase, before any buyer is contacted. The document is released after NDA execution, following the teaser, and it stays fixed once outreach begins so that all 40 to 80 contacted buyers price the same facts.
In a full 6 to 10 month sale process, the CIM is finished by the end of month three. In a process run alongside a live inbound offer, the same document is produced inside a compressed 4 to 6 month calendar.
How do buyers actually read a CIM?
A buyer’s first read of a CIM lasts about 30 minutes, and it is performed by an associate or corp dev analyst screening for reasons to pass. Serial acquirers such as Volaris screen a steady flow of CIMs and reject most of them.
The financials get read first, regardless of where the chapter sits in the document. Revenue mix, retention, concentration, and margin trajectory are checked against the buyer’s thesis before the narrative chapters get any attention.
A CIM is therefore built for a hostile skim rather than an admiring cover-to-cover read. The executive summary must survive on its own, and every chapter must lead with its conclusion.
Why does the CIM matter for the final price?
The CIM puts 40 to 80 buyers on an identical fact base at the same moment, which is what makes their bids comparable and the auction real. A founder negotiating alone shares information piecemeal, and the single buyer controls the frame.
That framing gap is measurable. The Proprietary Discount, the gap between what a serial acquirer pays in an unbanked bilateral negotiation and what the same business clears in a competitive process, runs 15 to 25 percent of enterprise value.
Founders weighing whether to produce these materials themselves should read Windsor Drake’s guidance on whether they need a banker, and founders who already hold an inbound offer should start from the offer-received hub.
Windsor Drake drafts the CIM inside every sell-side mandate, and a founder holding a live offer can commission the same materials on a compressed calendar through Approach Response.
Questions founders ask
Who writes the CIM, the founder or the advisor?
The advisor drafts the CIM and the founder supplies source data and reviews every claim. Windsor Drake builds the document during the 8 to 12 week preparation phase, and the founder signs off on each chapter because the founder will defend the contents in management meetings.
Is a CIM legally binding?
No. A CIM is an informational document and carries standard disclaimers. Its claims still matter legally, because they shape the representations and warranties in the purchase agreement, and a misstatement discovered in diligence invites a price retrade.
Does every buyer get the same CIM?
Yes. All contacted buyers receive an identical document after signing the NDA, which keeps indications of interest comparable. Buyer-specific positioning happens in management meetings, never in edited CIM versions.
Can a CIM include financial projections?
Yes, in the growth plan chapter, with a visible bridge from historical results to the forecast. A projection with no bridge from current numbers reads as fiction and invites the buyer to discount every other chapter.
How is a CIM different from a teaser?
A teaser is one anonymous page sent before any NDA, and it hides the company’s identity. A CIM is a 25 to 50 page named document sent after the NDA. The teaser earns the NDA, and the CIM earns the indication of interest.
What happens if a CIM claim fails in diligence?
The buyer reprices or walks. Roughly 1 in 3 signed LOIs fail to close on their original terms, and unsupportable seller claims are a leading cause, which is why Windsor Drake excludes any statement the data room cannot document.
