Startup Due Diligence Checklist: Prepare for Investor Questions

Ask the reviewing investor which business areas matter for this financing and who will need access. Requirements differ with stage, sector, geography and the structure of the proposed transaction. A hardware company may need manufacturing and supplier evidence; a software company may face more questions about data handling and customer retention. Keep a standard index, then add relevant specialist sections.

The SEC’s preparation guidance identifies an accurate cap table and financial statements as core materials. Begin by locating the current records and naming the person who can explain them. Mark missing items openly. Do not create an apparently complete file by substituting unsigned drafts for executed agreements or projected revenue for historical financial information.

Create a short index with a document name, reporting period, owner, status and explanation of why it matters. Use consistent names such as “Customer-revenue-summary_2026-08” instead of “final-v7-new.” Preserve prior versions internally, but direct the reviewer to the current approved copy. A small readme can explain definitions and identify material changes since the last update.

This checklist is an operating starting point, not a legal determination that every listed document is required. Have relevant advisers identify company-specific needs. For each category, ask whether the evidence is accurate, current and consistent with the financing narrative.

Choose a few important claims from the deck and trace them backward. If the deck states a recurring revenue figure, check the subscription schedule, adjustments and reporting date. If it mentions a major customer, confirm the legal entity and relationship stage. If a founder reports a particular ownership percentage, check the denominator and treatment of outstanding instruments and options.

In a hypothetical review, the deck reports twenty active customers while the finance schedule contains eighteen paying accounts. Investigation finds two unpaid pilots. The fix is not to rename the spreadsheet. Separate paid customers and pilots consistently across the deck, room and investor answers. Record the correction and tell existing reviewers when it materially changes information already supplied.

Reconciliation also exposes operational work. An unsigned contractor assignment, an unexplained liability or an expired supplier arrangement should become an issue to resolve with the appropriate adviser, not a document to hide.

Begin with summaries that answer the question without unnecessary personal or commercially sensitive detail. Provide underlying documents as the review progresses and access becomes justified. Confirm contractual restrictions and permissions before sharing customer information. Use individual accounts where practical, review access lists and remove access when it is no longer needed. An accessible public link is a poor substitute for a deliberate sharing decision.

Context matters as much as access. A technical report should state the environment and test conditions. A forecast should identify its version and assumptions. Customer references should be coordinated so people know who may contact them and why. Never share credentials or live production access merely to demonstrate that a system works; arrange a suitable demonstration or limited evidence package.

Keep a question log with the requester, answer owner, response, supporting file and date. This prevents inconsistent answers across investors and makes unresolved issues visible.

Due diligence and financing documentation inform each other. The NVCA model-document collection includes stock purchase, investor-rights and voting documents, illustrating that a financing involves more than the headline price. NVCA describes its models as starting points requiring tailoring. Use counsel to understand the actual documents and obligations involved in your transaction.

Finish each review cycle by closing answered questions and updating the open-issues list. For a hypothetical missing agreement, record what is missing, its business significance, the person addressing it and the expected next step. Avoid promising a completion date that depends on someone who has not agreed to the work.

After financing, retain a controlled archive of what was shared and signed, and turn recurring reporting commitments into operating responsibilities. The best preparation improves the company’s records even if a particular investor decides not to proceed. For an earlier assessment of whether to start fundraising at all, use the separate investment-readiness checklist.
