What evidence should an angel request before investing in a pre-revenue B2B SaaS startup?

Request evidence that corresponds to the company's current claims and the decision you are considering. Pre-revenue diligence should not pretend revenue history exists, but it can investigate customer behavior, product capability, team execution, and cash needs. Keep observations separate from founder projections.

Start with the decision

Build a claim-to-record map and name the largest unresolved assumption. Review negative evidence and missing information alongside the strongest examples. Use qualified specialists when the relevant technical, accounting, or legal question exceeds your competence.

The illustrative scenario

This is an educational workbook. The company or fund and all numerical inputs below are fictional. They are not ADIN results, customer claims, market benchmarks, or a forecast.

The fictional company is testing a reporting tool with three operations teams. Users attend demos, but no recurring contract is signed. The founder wants financing to complete integrations and test a repeatable sale.

A pilot conversation, active usage, an invoice, and a recurring commitment describe different evidence. Treat projected sales as assumptions and ask which milestone financing can realistically support.

Turn the scenario into an evidence decision

Consider a review of a pre-revenue B2B SaaS startup in which a confident explanation arrives before the supporting records. Start with the first question in the table. Write down what an answer would change: the next interview, the experiment's scope, a request for specialist review, or a decision to wait. A question without a consequence can produce a longer document while adding little understanding.

Next, inspect the record named in the table and record its date, owner, permission boundary, and limitations. Review permissioned pilot notes, usage records, customer references, and a dated cash forecast. Clarify what is confirmed by the customer rather than inferred by the founder. If the record contradicts the explanation, preserve both accounts and ask which definition, period, or workflow differs. Do not silently select the version that makes the opportunity look strongest.

Finish with a conditional statement: if the specified evidence supports the claim under these conditions, take the named next step; otherwise investigate the unresolved question. A diligence checklist organizes inquiry; it does not certify an investment or remove loss risk. The useful output is a clearer understanding of the assumptions, alternatives, and reasons for a decision. This worked exercise is about the decision process. It does not assert that a fictional company has met a real diligence standard or that a template can authorize an investment.

Use this worksheet

Answer the questions with a source, date, owner, and next action. Mark an unknown as unknown. Use public or permissioned information and involve a qualified specialist when a question requires expertise beyond the team’s competence.

1. Which claim matters most?
2. What record supports it?
3. What evidence contradicts it?
4. Who can independently verify it?
5. What remains unknown?

Questions specific to this scenario

• Who owns the customer's budget?
• What milestone comes before the next raise?
• Which projection has independent support?

Review permissioned pilot notes, usage records, customer references, and a dated cash forecast. Clarify what is confirmed by the customer rather than inferred by the founder.

A concrete next test

Ask a pilot participant to describe the last time the reporting problem occurred and the next approval needed for a purchase. Compare that account with the founder's pipeline stage. Record an explicit unresolved step rather than interpreting meeting attendance as contract intent.

Interpret the result

A diligence checklist organizes inquiry; it does not certify an investment or remove loss risk. The useful output is a clearer understanding of the assumptions, alternatives, and reasons for a decision.

Compare the current evidence with the specific next milestone. An attractive market story does not establish that this team can reach its buyer.
