How can an angel assess portfolio overlap before investing in a consumer product startup?

Assess overlap by the underlying exposures and dependencies of the portfolio, not only company labels. Different startups can share buyers, infrastructure, geography, financing conditions, or a single market cycle. Diversification does not eliminate the risk of loss.

Start with the decision

Create a look-through map using available information. Compare the new company's exposures with existing holdings and identify missing data. Use hypothetical examples for learning rather than prescribing a personal allocation or number of investments.

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 offers a paid learning app. Early signups followed a launch promotion, and the founder is testing whether users return without discounts. Marketing, support, and content costs vary across cohorts.

A download or free trial does not establish retention or willingness to pay. Separate acquisition cohorts, renewal behavior, refunds, and incentives before extrapolating growth.

Turn the scenario into an evidence decision

Consider a review of a consumer product 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 consented aggregate cohort data, paid renewals, acquisition spending, refunds, and changes in the product experience. Keep sponsored or incentivized usage 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. An exposure map is a discussion tool. It does not establish independence between outcomes or a safe portfolio size, and illiquid holdings may prevent adjustments when circumstances change. 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 buyers overlap?
2. What dependency is shared?
3. What information is missing?
4. Which adverse event affects several holdings?
5. How would the new investment change exposure?

Questions specific to this scenario

• Who renews without a discount?
• Which acquisition cohort is comparable?
• What happens after the promotion ends?

Inspect consented aggregate cohort data, paid renewals, acquisition spending, refunds, and changes in the product experience. Keep sponsored or incentivized usage visible.

A concrete next test

Compare a launch-promotion cohort with a later group using the same renewal and refund definitions. Ask what changed in price, acquisition channel, and product experience. Avoid attributing a blended retention change to the product before checking those differences.

Interpret the result

An exposure map is a discussion tool. It does not establish independence between outcomes or a safe portfolio size, and illiquid holdings may prevent adjustments when circumstances change.

Compare continued paid use with the initial launch spike. A narrow engaged cohort can be more informative than a large blended signup total.
