Due Diligence Depth
Definition
The level of detail and scrutiny applied by an investor in reviewing a company's financial materials. Due diligence depth increases with investment size and with the stage of the company. A Series A investor applies materially deeper financial due diligence than an angel investor because the investment amount is larger, the investor has greater legal and reputational accountability, and the company's financial history is longer and therefore more verifiable.
Common Misapplication
The most common misapplication is preparing the same depth of financial materials for all investor conversations regardless of investor category. A pre-seed investor requires different materials at a different level of detail than a Series A investor, and over-preparing for early conversations wastes time that should be spent on operations.
