An angel investor likes your pitch and asks for supporting documents. What should you send? Start with evidence behind the claims that matter: who owns the company, what customers actually do, what the business spends, and what the proposed investment would finance. Angel investor due diligence is easier to navigate when those answers connect to consistent records rather than another persuasive presentation.
This guide focuses on founders preparing an early-stage U.S. company for review. Its practical framework is simple: state the claim, identify the evidence, and disclose the unresolved issue. Requirements vary by investor, company and transaction. The Angel Investors core page explains the broader financing context; here, the question is how to make your specific business inspectable.
What angel investor due diligence is meant to verify
A pitch presents a case for investment. Diligence tests whether the available records support that case and what uncertainties remain. Cooley GO describes diligence as a review of relevant legal and financial documents before a transaction is finalized. That definition establishes the process, not a promise that completing it produces investment. Source: Cooley GO.
Initial screening versus deeper investigation
For preparation purposes, separate two questions: does this opportunity fit the investor, and can its important claims withstand investigation? An investor may decline because the sector or stage is outside their interests even when your records are accurate. Conversely, enthusiasm about the product does not resolve missing ownership documents or inconsistent financial figures.
Ask which requests are needed now, who coordinates the review, and how questions should be submitted. Do not assume every angel follows a formal committee process or identical checklist. The Angel Capital Association’s founder guidance expressly notes that a prospective investor may have a preferred checklist. Source: ACA.
Turn fundraising claims into evidence
Build a short evidence index before uploading documents. Each entry should connect a statement in the pitch to a dated record, an explanation of its scope, and any qualification. The following framework is an editorial preparation tool, not an official investor standard.
| Pitch claim | Evidence to organize | Question still to answer |
|---|---|---|
| Customers pay for the product | Contracts, invoices and payment records | Are these recurring subscriptions, pilots or one-time projects? |
| The founders own the company | Cap table, issuance documents and approvals | Do other securities or commitments affect ownership? |
| The company controls its technology | Assignments, licenses and contributor agreements | Which rights belong to others? |
| The investment funds a milestone | Cash forecast, hiring plan and spending assumptions | What changes if revenue arrives later? |
Team, product and customer claims
Prepare biographies that distinguish actual responsibilities from impressive affiliations. A founder’s former employer does not demonstrate what that person built. List relevant projects, current roles and references who can describe the work. ACA’s preparation guidance recommends current management resumes and references and discusses the possibility of background checks. Coordinate permissions before sharing personal information. Source: ACA.
For the product, identify what works today, what requires manual support and what remains on the roadmap. A recorded demonstration is useful context, but a demonstration alone cannot establish reliability across customers. Explain dependencies on outside infrastructure, licensed technology or specialist personnel. Label internal test results with the conditions under which they were obtained.
Customer evidence needs equally precise definitions. Separate leads from signed contracts, contracts from collected payments, and trial users from recurring customers. ACA specifically recommends substantiating pipeline and partnership statements made in a pitch. Source: ACA. For behavioral evidence, the Product-Market Fit Metrics article explains why cohorts, repeat usage and payment should be interpreted together.
For market claims, explain how you reached the number and which buyers the product can realistically serve. A large industry total is not evidence that your company can reach those customers. Prepare the customer segment, buying process, pricing assumptions and competing alternatives behind your opportunity estimate. Keep external market data separate from your own estimate of achievable sales.
Ownership, IP and company records
A cap table is an organized representation of ownership, not a substitute for the documents supporting it. Assemble formation records, stock issuance documents, relevant approvals and agreements affecting outstanding securities. Cooley’s sample VC request list includes charter records, capital stock, debt financing, intellectual property and other agreements. It is a historical institutional template, useful for identifying document categories rather than prescribing every angel’s requirements. Source: Cooley GO checklist.
Keep issued shares distinct from instruments that may become shares. Y Combinator describes a SAFE as a contract providing rights to future stock. Accordingly, a preparation schedule should identify outstanding SAFEs separately and retain their executed terms. Any modeled future ownership should state its conversion assumptions instead of being presented as current issued ownership. Source: Y Combinator.
For IP, prepare a record of creators, dates, agreements and third-party rights. Cooley’s patent guidance discusses assignments from inventors and agreements with employees and service providers. Source: Cooley GO. Do not assume that paying a developer resolves every ownership question. Ask counsel to examine actual agreements and applicable law, particularly where work began before incorporation. The Company Formation page places these records within the broader company setup.
Prepare financials, runway and the use of funds
Present historical results separately from forecasts. State the reporting period, currency and accounting basis. Explain differences among invoiced amounts, recognized revenue and cash collected, rather than placing them under one ambiguous sales label. A forecast should show its assumptions; it should not be described as contracted revenue simply because management expects to win customers.
A practical preparation package can include recent financial statements, cash balances, liabilities and a forecast connecting expenditure to milestones. These categories build on Cooley’s sample request list, which asks for financial statements and debt records. The specific forecast structure below is our analytical suggestion, not a universal diligence requirement.
Show how the proposed funding supports a measurable objective: completing a product, validating a sales channel or reaching a defined customer milestone. Distinguish essential spending from spending that can be deferred. Add a downside case with slower collections or sales. This lets a reader see which assumptions threaten the plan before debating whether its headline funding amount is sufficient.
For a simplified illustration, $240,000 of unrestricted cash divided by a constant $30,000 monthly net cash outflow gives eight months. That arithmetic assumes unchanged spending and receipts, with no additional commitments or financing. A monthly cash forecast is more informative when hiring, payment timing or seasonal demand changes. The Funding Rounds page explains how financing connects with runway and business milestones.
A worked example: reconciling the pitch with the records
Imagine a software startup whose deck says it has twenty customers generating $10,000 in monthly recurring revenue. All figures in this example are hypothetical. The founder’s evidence index reveals sixteen active subscriptions paying $500 each per month and four organizations that bought a one-time $500 pilot. Assume the subscription fees are recurring and no other recurring revenue exists.
The subscriptions support $8,000 of monthly recurring revenue. The pilot purchases total $2,000, but they do not support another $2,000 recurring every month. The business can explain twenty purchasing organizations over a specified period while reporting sixteen current subscribers. Those are different measurements. The correction does not establish dishonesty; it establishes the need for clearer definitions and a revised deck.
Now suppose the cap table shows only the founders, while the document folder contains an executed SAFE. The useful response is to identify the instrument, reconcile the records and model its potential effect under stated assumptions. It is not to invent an exact present ownership percentage. Business evidence, legal records and modeled outcomes should remain distinguishable.
Finally, assume a former contractor’s contribution lacks an available signed agreement. Record what was contributed, which documents are missing and who will investigate. Do not describe the issue as resolved because everyone remembers an informal understanding. The preparation framework makes the gap visible without pretending to decide its legal consequences.
Organize the review and disclose unresolved issues
Controlled document access and an issue log
Use a document index with consistent names, dates and version labels. Designate one person to coordinate responses. As a practical control, share sensitive material with appropriate permissions and ask advisers about confidentiality and redaction. Avoid uploading unnecessary personal data or customer information simply because a folder exists for it.
Maintain an issue log with four fields: question, available evidence, unresolved point and responsible person. A missing signature, disputed invoice and untested sales assumption are different problems; grouping them as miscellaneous risks obscures what needs action. Preserve earlier versions when correcting figures so the reviewer can understand the change.
Prioritize discrepancies that change the investment story. A typographical error is different from a customer total that includes canceled accounts. For each material correction, explain whether it changes the historical result, the forecast or both. If verification is incomplete, provide the available record and the remaining question rather than offering a confident answer that later needs withdrawal.
Preparation also does not replace securities-law compliance. The SEC states that offers and sales of securities must be registered or rely on an available exemption. Obtain advice on the applicable offering pathway before treating a well-organized data room as permission to solicit investment. Source: SEC.
What preparation can and cannot establish
Good angel investor due diligence preparation makes evidence easier to inspect and uncertainty harder to hide. It cannot guarantee funding, establish future product-market fit or make a risky investment safe. Start with the pitch’s material claims, reconcile them with dated records, and disclose gaps with a concrete follow-up plan. The Private Company Lifecycle hub connects this review with validation, financing and later company development.
