Angel investors
What assumptions drive an angel valuation discussion for a deep tech startup?
a deep tech startup: A valuation discussion should make the assumptions and the investment instrument visible.
A valuation discussion should make the assumptions and the investment instrument visible. Comparisons can inform the discussion without establishing a correct price. Distinguish price, ownership, dilution, rights, and the capital needed to reach future milestones.
Start with the decision
Use a hypothetical ownership bridge to expose the effect of round size and pricing assumptions. Compare actual terms with qualified advisers. Do not translate a market multiple or another company's financing into a personalized recommendation.
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.
A simplified priced-round and cash comparison
Assume a fictional priced equity round of $5,000,000.00 at a pre-money value of $20,000,000.00. A $50,000.00 check divided by the simplified post-money amount produces 0.200% ownership. If a later issuance reduces existing holders by an assumed 24%, that interest becomes 0.152% without participation.
The exercise omits option pools, convertibles, preferences, fees, side agreements, and other actual terms. It is not a SAFE conversion model or a recommendation to invest or preserve ownership. Actual cap-table and document analysis belongs with qualified advisers. A percentage of ownership does not specify eventual proceeds or protect against total loss.
The fictional company's $1,500,000.00 of cash divided by $140,000.00 of monthly use gives 10.7 months under a constant-use assumption. 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. Connect that simple quotient to dated obligations and milestones before drawing a conclusion about financing needs or progress.
| Item | Illustration |
|---|---|
| Assumed pre-money value / round size | $20,000,000.00 / $5,000,000.00 |
| Fictional investor check | $50,000.00 |
| Simplified initial ownership | 0.200% |
| Assumed later dilution | 24% |
| Ownership without later participation | 0.152% |
| Cash / constant monthly use | $1,500,000.00 / $140,000.00 |
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 instrument is proposed?
- What ownership follows under the terms?
- What dilution is possible?
- What rights accompany the interest?
- Which comparison is genuinely relevant?
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
Simple arithmetic can clarify a discussion while omitting option pools, convertibles, fees, preferences, and later terms. State those omissions before using the model to assess a real transaction.
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.
