How can an angel write a decision memo about a climate software startup?
a climate software startup: Write a decision memo that separates the company story from the investor's reasoning.
Write a decision memo that separates the company story from the investor's reasoning. State the question, evidence, competing interpretations, terms needing review, and unresolved risks. A memo should remain understandable after enthusiasm for the meeting fades.
Start with the decision
Use a claim-evidence-judgment structure and include a reason the investment could fail. Record what would change the conclusion. Keep any personal suitability or allocation decision separate from a generic educational example.
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 product helps building operators reconcile energy data. A facilities team uses the dashboard, while a finance manager approves spending. Deployments depend on meter access and consistent records across properties.
A claimed environmental benefit is different from a measured change attributable to the product. Separate data quality, operational action, and any externally verified result.
Turn the scenario into an evidence decision
Consider a review of a climate software 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. Inspect permissioned meter samples, installation requirements, operator references, and the method used for claimed savings. Keep comparison periods and missing readings visible. 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 good memo can make an eventual mistake more informative by preserving the original assumptions. It cannot turn an uncertain early-stage investment into a predictable outcome or transfer responsibility to a template. 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.
| Item | Illustration |
|---|---|
| Decision question | What decision is being considered? |
| Case-specific constraint | A claimed environmental benefit is different from a measured change attributable to the product. Separate data quality, operational action, and any externally verified result. |
| Record to inspect | Inspect permissioned meter samples, installation requirements, operator references, and the method used for claimed savings. Keep comparison periods and missing readings visible. |
| Comparison to preserve | Compare the full deployment process with the operator's current reporting. A useful dashboard still needs someone able to act on its findings. |
| Unresolved case question | Who supplies reliable data? |
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.
- What decision is being considered?
- Which evidence is strongest?
- What is the contrary case?
- Which terms need review?
- What would change the conclusion?
Questions specific to this scenario
- Who supplies reliable data?
- Which savings are actually measured?
- How long does a property rollout take?
Inspect permissioned meter samples, installation requirements, operator references, and the method used for claimed savings. Keep comparison periods and missing readings visible.
A concrete next test
Trace one claimed operational saving from raw meter data to a documented action and comparison period. Ask which part is measured and which part is inferred. Keep missing readings and unrelated changes visible before using the claim in an investment discussion.
Interpret the result
A good memo can make an eventual mistake more informative by preserving the original assumptions. It cannot turn an uncertain early-stage investment into a predictable outcome or transfer responsibility to a template.
Compare the full deployment process with the operator's current reporting. A useful dashboard still needs someone able to act on its findings.
