Angel investors
What should an angel clarify about a SAFE investment in a deep tech startup?
a deep tech startup: Read a SAFE as a specific agreement rather than a synonym for equity with a fixed ownership percentage today.
Read a SAFE as a specific agreement rather than a synonym for equity with a fixed ownership percentage today. Caps, discounts, conversion mechanics, amendments, and other terms can change the analysis. The document and applicable law control the actual arrangement.
Start with the decision
List the provisions needing explanation and have qualified counsel review them. Keep any simplified numerical illustration separate from the actual instrument. Compare what is known at signing with what depends on later events.
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 is developing a sensing component with a laboratory prototype. Commercial customers require validation outside the lab before a design win. Manufacturing and qualification milestones compete for the same runway.
A successful laboratory test does not establish production reliability or buyer adoption. Keep technical feasibility, manufacturability, customer qualification, and commercial commitment separate.
Turn the scenario into an evidence decision
Consider a review of a deep tech 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 dated test protocols, repeatability results, independent technical references, and a milestone budget. Distinguish a customer's evaluation agreement from an order. 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 educational worksheet should make questions clearer, not replace legal interpretation. Avoid borrowing a SAFE example from a different form and assuming the ownership arithmetic transfers unchanged. 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.

| Decision question | Which form is being used? |
| Case-specific constraint | A successful laboratory test does not establish production reliability or buyer adoption. Keep technical feasibility, manufacturability, customer qualification, and commercial commitment separate. |
| Record to inspect | Request dated test protocols, repeatability results, independent technical references, and a milestone budget. Distinguish a customer's evaluation agreement from an order. |
| Comparison to preserve | Compare the next financing milestone with the resources and dependencies needed to reach it. Use qualified technical reviewers for claims outside the investor's expertise. |
| Unresolved case question | What test can be reproduced? |
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.
- Which form is being used?
- What triggers conversion?
- Which terms affect the calculation?
- What happens under other outcomes?
- Who reviewed amendments and side agreements?
Questions specific to this scenario
- What test can be reproduced?
- Which milestone depends on a third party?
- What changes between prototype and production?
Request dated test protocols, repeatability results, independent technical references, and a milestone budget. Distinguish a customer's evaluation agreement from an order.
A concrete next test
Ask a qualified technical reviewer to identify a repeatable test that distinguishes laboratory feasibility from the next commercial milestone. Record the equipment, conditions, dependencies, and evidence needed. A dramatic demonstration should not substitute for the specified validation process.
Interpret the result
An educational worksheet should make questions clearer, not replace legal interpretation. Avoid borrowing a SAFE example from a different form and assuming the ownership arithmetic transfers unchanged.
Compare the next financing milestone with the resources and dependencies needed to reach it. Use qualified technical reviewers for claims outside the investor's expertise.
