The Startup Diligence Process allows an Investor to investigate all Legal, Financial, and Operational aspects of a startup to gather information on the characteristics of the startup and any potential hidden risks before providing funding (the Investor’s due diligence). Pursuing the Diligence Process is crucial for providing critical verification of facts as well as unearthing any potential hiding liabilities resulting from a startup’s past. Failure to perform sufficient diligence could have a significant negative economic, legal, or reputational impact on the Investor or Startup’s Founder.
Definition and Purpose of Due Diligence
Due diligence refers to the process in which investors conduct detailed research and investigation into a startup before making an investment, into the accuracy of any claims made by the startup to an Investor. The purpose of this due diligence research and investigation is to validate any claims as well as investigate any unknown or undisclosed liabilities. According to the SEC, Investors are said to put forth effort to perform due diligence investigations by reviewing an Investor’s financial records. Thus, the investor is reducing the likelihood of incurring potentially serious risks in the Legal, Financial, and Operational sectors.
Key Due Diligence Areas
The primary focus areas of diligence that an Investor will evaluate during due diligence are as follows:
- Legal/Regulatory – Startup’s Corporate Charter, Agreements, Licenses, Permits, and existing/Open Litigation or Regulatory Issues, as well as whether the startup complies with all relevant federal and state laws (i.e. Labor Laws, Securities Laws, Intellectual Property Laws, Tax Laws, etc.).
- Financial/Tax – Startup’s Financial Statements, Budgets, Cash Flow, and Tax Returns; verify completeness and correctness of all accounting records and whether there are any outstanding obligations or debts that have not been disclosed.
- Corporate Governance – Cap Table, Articles of Incorporation, board of directors/shareholders, bylaws, and minutes of all board/shareholder meetings. As stated by the SBA guidelines, “investors will look at the Diligence documents as a significant factor in determining how the startup is owned and controlled;”
- Intellectual Property – Patents, Trademarks, Copyrights, Trade Secrets, and Key Software; verify that all Intellectual Property is owned by the startup and free and clear from any encumbrances.
- Market/Commercial – product/service, market size, competition, and customers; verify that Startup’s product/service has a valid product market/fit and demand; and
- Technology/IT/Security – Technology, Code Base, IT Infrastructure, and Data Security: review Technology to determine if it can scale; and if it is compliant with all applicable Laws regarding data privacy.
- Human Resources – resumes of founders/key team members, Employment Contracts for Independent Contractors, and summary of Equity Incentives; ensure that there are no employee retention issues or undisclosed disputes with respect to Independent Contractors.
- ESG and Risk Management Compliance – Environmental, Social and Governance: per the new EU Guidelines, Investors must identify and analyse the human rights and environmental impact resulting from the business operations of the startup. Investors are very diligent in reviewing, assessing, and analysing ESG matters at a startup (e.g. Legal Compliance, Labor Practices, Ethical Supply Chain, Environmental Liabilities) to minimize any potential Regulatory Liability and/or Reputational Liability.
Due Diligence Process and Timeline
The standard process involves the following:
- Step 1: Founders meet with potential investors to pitch their business; if potential investors are interested, they sign a non-disclosure agreement and execute a letter of intent (LOI) or term sheet to memorialize the key terms of this potential investment.
- Step 2: Founders provide their investors with all the necessary, organized documentation (financial statements, corporate records, contracts, intellectual property, etc.) in a secure data room. Investors will review the documentation in detail and will often have question and answer sessions with the founders.
- Step 3: After reviewing all the documentation, various experts (lawyers, accountants and technical professionals) will evaluate the information in each of the above categories and will look for any discrepancies, issues or risks. The experts will prepare a report to the Founder on their findings.
- Step 4: Once the experts’ reports are delivered to all parties, the parties will work toward finalizing the terms of the investment agreement. This step is usually a negotiation between the parties, where the parties may agree to alter the price, warranties, indemnities or warranties in the investment agreement. Once the parties agree to all the terms and sign the necessary documentation, the investment will close, and the funds will be transferred.
Common Red Flags and Mitigation
During startup due diligence, investors look for warning signs that may indicate potential risks. Common red flags include undisclosed debts or pending lawsuits, errors in the capitalization table, and missing or unassigned intellectual property such as patents or software code. Financial inconsistencies can also raise concerns, especially when financial statements are unsupported by clear records or contain unusual transactions. In addition, weak cybersecurity practices, regulatory compliance issues, or environmental, social, and governance (ESG) concerns-such as environmental liabilities or labor rights violations-may signal operational or legal risks.
To reduce these risks, investors may negotiate legal protections such as representations and warranties, place funds in escrow for potential indemnity claims, adjust the valuation of the company, or require the startup to resolve certain issues before closing the deal. Thorough due diligence helps investors identify problems early and avoid unexpected liabilities.
Due Diligence Checklist
For Investors: Prepare and compile a list of documents you will want to review. You will require 3-plus years of corporate legal formation papers, capitalization table with current stockholder agreements, financial statements and tax returns for the previous three years, IP registrations and licenses including patents, major contracts, insurances and potential disputes with investors (e.g., customers, suppliers, employees) and interview with founders and key executive officers/managers.
For Founders: You should prepare your records, so they are up to date. Maintain your corporate and equity records (minutes of board meetings, capitalization table) always. Ensure your IP assignments and non-disclosure agreements are completed. Maintain accurate and timely financial statements and projections including your financial projections covering all foreseeable development. Document your market analysis, product development and any policies relating to risk management. A well-organized virtual data room will substantially assist with a quicker process.
