What Is Due Diligence in Investment?
Due diligence is the investor's investigation of a company before completing an investment. Learn what investors look at and how to prepare.
Key Takeaways
- Due diligence is the investor's verification of everything in your pitch before money is transferred
- It covers commercial, financial, legal, and technical areas
- A well-organised data room dramatically speeds up due diligence and signals management quality
- Material surprises discovered in due diligence can kill a deal — disclose proactively
What due diligence is
Due diligence is the process by which an investor investigates and verifies the information presented by a company before completing an investment. It is the investor's way of confirming that what they were told in the pitch is accurate, that there are no material undisclosed risks, and that the legal and financial structure of the company is clean and investable. Due diligence typically begins after a term sheet is signed and takes 4-12 weeks depending on the investment size and the investor's thoroughness.
What investors examine
Commercial due diligence examines the business model, market size, competitive landscape, and customer evidence — including speaking directly to reference customers. Financial due diligence reviews historical accounts, management accounts, financial projections and their assumptions, unit economics, and cash flow. Legal due diligence checks company structure, cap table, IP ownership, employment contracts, customer and supplier contracts, and any outstanding litigation or regulatory issues. Technical due diligence (for tech companies) assesses code quality, architecture, scalability, and security.
Preparing a data room
A data room is a secure online folder (Google Drive, Notion, or specialist platforms like Caplinked or Ansarada) containing all the documents an investor needs for due diligence. A well-organised data room includes: company registration documents, accounts and management accounts, cap table, key contracts, IP assignments, employment agreements, terms and conditions, privacy policy, pitch deck, and financial model. Having a clean data room ready before starting to fundraise signals operational maturity and dramatically accelerates the process.
The principle of proactive disclosure
The most damaging due diligence outcomes are surprises — information the investor discovers that was not voluntarily disclosed. A historic legal dispute, a cap table discrepancy, a customer concentration risk, or a technical debt issue discovered during due diligence — after the term sheet but before closing — can cause significant repricing or deal termination. The better approach is proactive disclosure: raise material issues early in the investor relationship, before the term sheet, rather than hoping they go unnoticed. Investors value honesty and almost always find problems eventually anyway.
What investors cannot see
Not all due diligence risks are in documents. Investors conduct reference calls — speaking to former colleagues, industry contacts, and existing investors — to understand how founders operate, treat people, and handle adversity. Glassdoor reviews, public social media, and industry reputation all feed into investor perception. Founders who are consistently spoken well of by people who have worked with them have a significant fundraising advantage over those who are not. Build a reputation worthy of the capital you want to raise.
