Common types

Common types include confidential information memorandum (CIM), internal investment memo, private placement memorandum, lender memo, transaction memo, and deal committee memo. Each serves a different audience and level of disclosure.

Who uses them

Founders, sellers, investors, banks, private equity teams, venture capital teams, corporate development teams, lenders, and investment committees may use investment memorandums during fundraising, sale processes, financing, or internal approvals.

Common sections

Common sections include company overview, market overview, product or service description, financials, management team, transaction rationale, risk factors, legal or compliance notes, and supporting appendix materials.

How they are shared during diligence or fundraising

Investment memorandums are often shared early in a process, sometimes before full diligence access is granted. Teams may need to control who can view, download, forward, or print the document.
