How can an angel assess portfolio overlap before investing in an AI application 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 team sells an AI assistant to small support departments. A demonstration works on familiar examples, but the product is still testing performance on new customers' queues. Founder time currently covers many exceptions.

Separate model output from completed customer work. A software revenue claim needs a matching view of model usage, human delivery, customer support, and rework.

Turn the scenario into an evidence decision

Consider a review of an AI application 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 a permissioned evaluation sample, customer usage cohorts, an exception log, and a cost model that includes human work. Keep actual results distinct from roadmap features. 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 reviews failures?
• How much founder work supports each account?
• Which results hold on unseen examples?

Request a permissioned evaluation sample, customer usage cohorts, an exception log, and a cost model that includes human work. Keep actual results distinct from roadmap features.

A concrete next test

Observe a permissioned workflow where the assistant fails or needs founder intervention. Record the human time and what the customer sees. Compare that case with the demo so the diligence discussion addresses delivered work rather than only the best familiar example.

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 the promised workflow with the delivered workflow. The relevant question is whether adoption and delivery economics improve together.
