Confidential Information Memorandum Writing

A Confidential Information Memorandum — also called a CIM, IM, or information memorandum — is the primary sell-side M&A document shared with NDA'd strategic and financial buyers. It typically runs 30–80 pages and covers the business, market, operations, management, financials, and growth outlook in enough depth for a buyer to move from interest to indicative bid. In our experience writing CIMs across insurtech, education, lithium and batteries, real estate, and deep tech, the CIM is the single most-read document in any M&A process — buyers open it, print it, and annotate it.

A teaser is a 1–2 page anonymous summary shared pre-NDA. A CIM is the 30–80 page NDA'd document that follows — the sell-side M&A document proper. An offering memorandum is a legally-defined securities-law disclosure used in private placements (Reg D, for example) — similar structure, different legal purpose. A pitch deck is a 15–25 slide visual narrative used in venture fundraising. CIMs and offering memorandums get confused most often; the simple test is who the reader is (NDA'd M&A buyer vs regulated securities investor) and whether a lawyer signs off on disclosure language.

Typically a sell-side M&A advisor, boutique investment bank, or specialized CIM writer — in close coordination with the founder, CEO, and CFO. Big banks assign analysts to draft and an MD to review. Boutique M&A advisors like Waveup write CIMs directly with senior authorship — ours are written or reviewed by Olena Petrosyuk, Partner, with 10+ years in M&A (ex-Lazard, JP Morgan, Oliver Wyman). Founder-led CIMs without advisory support are rare and usually visible to buyers within the first two pages.

30–80 pages, depending on complexity. Small-business and single-entity deals sit at 30–40 pages. Growth-stage and mid-market deals run 50–80. Multi-entity groups, carve-outs with transition services, or cross-border platforms can push 80–120. Longer isn't better — buyers skim. We aim for the shortest CIM that closes the investment case without forcing the buyer to ask the basics in Q&A.

4–6 weeks for a standard engagement; 2–3 weeks expedited with complete data and a decisive founder. Week 1 is discovery and thesis. Weeks 2–3 are drafting alongside the financial model. Weeks 4–6 are normalization, legal review, data-room wrap, and buyer-perspective polish. If data is incomplete or the founder is bandwidth-constrained, timelines extend — not because drafting is slow, but because diligence review takes longer than the draft itself.

Nine sections: executive summary, company overview, business and products, market and industry, operations and supply chain, management and organization, financials (historical + projected + normalized EBITDA + working capital + capex), growth outlook, and appendices. Every section earns its place. Numbers tie back to the financial model. Market claims cite primary sources. Management bios match LinkedIn but don't read like it.

Our CIM engagements start at $10K and scale with scope — typically 4–6 weeks retainer-based. An Express CIM (30–40 pages, single entity) anchors the lower end. A Standard CIM (50–80 pages with model, valuation, and data-room index) sits in the middle. A CIM + Deal Support engagement layers on full M&A advisory through close. We don't charge success fees on CIM-only engagements — the retainer is the fee. For full sell-side M&A execution with a success-fee component, see our M&A advisory page.

After the teaser and NDA. The standard sequence: (1) teaser — anonymous 1–2 pager to qualify buyers; (2) NDA signed by serious buyers; (3) CIM released to NDA'd universe; (4) management presentations to top 5–10; (5) indicative bids (IOIs) into a bid deadline; (6) LOI with the lead buyer; (7) confirmatory diligence into close. The CIM sits between NDA and indicative bids — the period when most of the buyer's investment committee will read it.

A CIP is a deck-format CIM — 40–60 slides instead of a 50-page document. CIPs work well when buyers prefer visual formats, when the story is heavily graphic (real estate, consumer brands), or when the process is moving fast. Traditional CIMs still win for data-heavy deals — industrial, financial, multi-entity — where prose and tables carry more information density than slides. We deliver both formats; the choice depends on the buyer universe and asset type, not fashion.

No. Templates don't close deals — customized narrative does. Every buyer universe, sector, and transaction has a different weighting of what matters; a template that works for a SaaS Series C CIM won't work for a lithium-battery carve-out. We write CIMs from the data up, not the template down. If you want a general education on CIM structure, our 9-section anatomy above is the best place to start.

Sometimes. Seed and Series A rounds run on a pitch deck and financial model — no CIM needed. Series B+ growth rounds, PE minority investments, private placements, and approaches to strategic investors often call for CIM-level depth. If you're raising equity, our fundraising consulting page covers the full stack including when a CIM is the right artifact vs a deck. The test is simple: if the reader will build their own financial model off your document, you need a CIM.

Both — as separate engagements. The CIM itself is a standalone 4–6 week retainer. Most clients layer it with a custom financial model, valuation, and data-room prep at the same time. For full sell-side advisory — buyer outreach, LOI negotiation, diligence Q&A, and closing support — see our M&A advisory engagement. The CIM page is the document deep-dive; the M&A page is the full transaction process.

Yes, under NDA. Our named CIM references include an 80-page lithium-battery divestment CIM (subsequently secured $20M in acquisition financing), a Series C insurtech CIM, and an education-sector cross-border strategic-review CIM — three of the cases profiled on this page. Full redacted CIMs are shared with prospective clients after a 30-minute discovery call and mutual NDA. We don't publish PDFs publicly — buyer universes overlap, and confidentiality is the point of the document.

Insurtech, education, lithium and batteries, real estate, e-commerce, B2B SaaS, healthtech, CPG, industrials, and deep tech — across 64 countries. We've written CIMs for carve-outs of global manufacturing groups, multi-entity cross-border platforms, single-asset real-estate LP memos, and venture-backed SaaS businesses selling to PE. If your sector isn't listed, ask us — sector coverage in our 600+ company portfolio is broader than the headline list.

Unforced errors, almost every time. Unrealistic projections no buyer's model supports. Undisclosed customer concentration that surfaces in QoE. Missing EBITDA normalization. Market sizing that doesn't reconcile with competitor filings. Weak growth narratives where the capital ask outpaces the plan. Management bios that read like a careers page. We catch all of these in a CIM before the buyer's analyst does — that's the point of the buyer-perspective review on every engagement.

Primary language is English — which covers 90%+ of cross-border buyer universes. We've delivered CIMs supporting transactions in 64 countries across six continents. Arabic, Spanish, and French translations are supported on request for domestic buyer subsets; we typically author in English and produce localized versions for specific regional readers rather than translating the whole CIM by default.
