How can an angel distinguish references from independent evidence for a hardware startup?

a hardware startup: Distinguish a source's direct observation from their opinion, inference, or relationship with the company.

Distinguish a source's direct observation from their opinion, inference, or relationship with the company. References can be informative and biased at the same time. Important claims deserve a provenance trail and, where feasible, corroboration.

Start with the decision

For each claim, record the source, relationship, date, actual observation, and available supporting record. Seek permission before sharing private statements. Preserve contradictions instead of selecting only the reference that supports the preferred decision.

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 team has a working prototype of a monitoring device and early customer trials. Component purchases, assembly, testing, and field support must be funded before units become recurring revenue or repeat orders.

A prototype bill of materials omits some production costs. Yield, rework, inventory, shipping, and warranty assumptions can materially change the cash needed for delivery.

Turn the scenario into an evidence decision

Consider a review of a hardware 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. Request supplier quotes, prototype and production cost distinctions, test results, customer trial evidence, and a cash schedule that includes inventory timing. 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. Source quality depends on relevance and independence as well as reputation. A detailed firsthand account can answer a narrow question while remaining insufficient to support a broader claim about the company. 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. What was directly observed?
  2. When was it observed?
  3. What relationship exists?
  4. Can a record corroborate it?
  5. Which source disagrees?

Questions specific to this scenario

  • Which costs are quoted versus assumed?
  • What happens when yield falls?
  • Who supports failed field units?

Request supplier quotes, prototype and production cost distinctions, test results, customer trial evidence, and a cash schedule that includes inventory timing.

A concrete next test

Compare the prototype cost list with a hypothetical small production batch. Ask which supplier quotes are current and where yield, rework, shipping, or field support enter the cash plan. Keep working capital timing separate from a per-unit margin calculation.

Interpret the result

Source quality depends on relevance and independence as well as reputation. A detailed firsthand account can answer a narrow question while remaining insufficient to support a broader claim about the company.
