How to compare valuation caps and discount provisions for SAFE Financing Transactions

Compare SAFE economics by reconstructing each instrument’s conversion formula, not by sorting headline valuation caps. From the company’s perspective, the workflow is to verify operative documents, extract cap and discount language, reconcile capitalization definitions, and model comparable financing scenarios. Record contractual facts separately from assumptions and unresolved questions. The deliverable is a source-linked SAFE terms comparison showing which pricing mechanism controls, illustrative conversion shares, and the decisions or missing evidence that prevent a reliable dilution assessment.

When to use this workflow

Use this workflow when company counsel or an in-house team assesses outstanding SAFEs before another SAFE issuance, a priced equity financing, or investor diligence. It also helps evaluate proposed terms against existing instruments.

The scope is financing-conversion economics: caps, discounts, capitalization denominators, and related amendments or side letters. Analyze exit and dissolution economics separately; do not substitute their definitions for financing definitions.

This is a US company-side workflow, with Delaware-specific corporate authorization observations. Contract rights depend on executed language, governing law, facts, and deal context. Securities exemptions and applicable state requirements remain separate workstreams; completing this comparison does not resolve them.

What you need

Collect:

• Executed SAFEs, signature pages, amendments, waivers, and side letters, including MFN provisions and election records.
• Purchase amounts, acceptance and funding evidence, and cancellation or replacement records.
• Dated capitalization records, other convertibles, granted and promised options, and reserved pool shares.
• Financing-price or valuation assumptions, new money, proposed pool changes, and share-class terms.
• Relevant charter documents and approvals if the comparison may support an issuance or amendment decision.

Give every document a stable ID. Assign a company custodian to missing inputs. Preserve drafts and superseded versions without treating them as operative. An unsigned form supports analysis of proposed wording, not a conclusion about an investor’s binding economics.

Use the template

The companion template is SAFE Financing Transactions — SAFE terms comparison. Copy this table into your working document or spreadsheet. Use one row per instrument and scenario.

“SAFE / source” identifies the investor, document ID, and clause or page supporting the terms. Link amendments and side letters. “Cap / basis” records the amount and contractual pre-money or post-money designation. “Rate / discount” preserves the stated rate and separately expresses the economic reduction.

“Denominator” references the capitalization definition and calculation schedule. “Scenario / result” references model cells for assumptions, candidate prices, selected price, and shares. Keep detailed calculations outside the summary table, with traceable cell references.

“Gap / exposure” distinguishes an adverse term, missing evidence, and an interpretive question. “Action / owner” includes the responsible person, target date, and closure evidence. For a verified item, state what was checked rather than leaving status ambiguous.

Step by step

1. Establish the operative instrument population

Reconcile the SAFE register against executed documents and company records. Identify each purchase amount, execution status, and amendment chain. Investigate conflicting amounts rather than treating the latest spreadsheet as controlling.

Group instruments by provisions: cap-only, discount-only, combined cap-and-discount, or economics dependent on an election or later terms. Check related side letters before grouping instruments together.

Record: a baseline row for each SAFE, source IDs, operative status, and unresolved replacement or amendment questions. Do not aggregate instruments merely because they share a cap.

2. Extract and normalize the pricing language

Capture the cap, stated Discount Rate, financing-price definition, conversion formula, and selection rule. Preserve the mathematical meaning rather than relying on labels.

An 80% rate multiplied by financing price produces a 20% economic discount. The SEC-filed CapCO2 form uses that structure and selects the Safe Price or Discount Price producing more shares. This is example wording, not a universal SAFE rule, evidence of execution, or a market benchmark. See Exhibit A, opening terms and §2. (sec.gov)

Do not discount the cap-derived price unless the instrument requires it. Check whether the financing price itself remains an available conversion alternative.

Record: cap, basis, stated rate, economic discount, selection rule, and pinpoint citations. Mark absent terms “not present,” not zero.

3. Reconstruct each capitalization denominator

Follow the full defined-term chain behind the cap price. Map issued shares, options, promised options, unissued pool shares, other SAFEs, notes, and financing-related pool increases to dated records. Identify exclusions explicitly.

A post-money label alone does not establish the denominator. YC explains that its post-money cap is post-SAFE money, not post-priced-round money. Use that explanation only where the executed instrument follows the relevant design. See the YC Post-Money SAFE User Guide, introduction. (bookface-static.ycombinator.com)

Where converting instruments enter one another’s denominators, document and solve the interdependent calculation; do not substitute an unsupported fixed total.

Record: schedule references, included and excluded categories, source dates, and classification questions. Maintain separate schedules for different definitions, even if current totals coincide.

4. Build comparable financing scenarios

Use shared financing assumptions while preserving each instrument’s formula. Test a lower-priced round, a higher-priced round, and a scenario near the point where candidate prices coincide. Add pool-change sensitivities where relevant.

For an instrument expressly using a fixed denominator, cap price equals cap divided by contractual capitalization; discount price equals financing price multiplied by the stated rate. Divide purchase amount by the contractually selected conversion price. Apply these calculations only where supported by the instrument.

Keep financing price, new money, and pool assumptions visible. If price is derived from a valuation, reconcile its denominator separately. Do not calculate final ownership without all relevant post-financing capitalization components.

Record: scenario IDs, assumption cells, candidate and selected prices, illustrative shares, and rounding treatment. Flag conditional outputs.

5. Assess differences that headline prices conceal

Compare outputs across scenarios. Different denominators can reverse the ranking suggested by cap amounts; discounts can produce different outcomes as financing price changes.

Check conversion trigger, timing, and share class alongside price. The CapCO2 example converts at the initial Equity Financing closing using purchase amount divided by Conversion Price. Do not assume other instruments use that trigger or formula. See Exhibit A §1(a). (sec.gov)

Separate SAFE conversion shares from shares purchased through participation rights. YC’s optional pro rata side letter addresses participation in the converting financing; the company’s executed side letters determine its actual obligations. See the YC guide, pro rata rights discussion. (bookface-static.ycombinator.com)

Record: controlling mechanism, share-class questions, participation assumptions, and why each difference matters to the company.

6. Resolve exceptions and obtain company decisions

Prioritize uncertain operative terms, unsupported denominators, potentially applicable elections, and materially different outcomes. Give each issue an owner and evidence-based closure requirement.

If economics may change, identify contractual consent and corporate approval requirements. For Delaware corporations, §157 addresses stock-acquisition rights or options, subject to the charter, and specifies how issuance and acquisition terms are established. Counsel must determine its application to the particular SAFE and additional approval requirements. See DGCL §157(a)–(b). (delcode.delaware.gov)

Record: accepted interpretation or proposed remediation, decision-maker, evidence, and model revision. Keep unresolved outputs conditional. A spreadsheet revision is not evidence that contractual terms changed.

Worked example

Fictional scenario: Alder Circuit, Inc. compares three fictional executed SAFEs, each with a $400,000 purchase amount. Scenario S1 assumes a $2.00 financing price. All three expressly convert at the initial financing closing into the same fictional preferred series. The cap-bearing instruments use fixed pre-money capitalization definitions excluding converting instruments and financing-related pool increases. These are invented provisions, not YC post-money mechanics.

A is cap-only at $8 million. B is discount-only with an 80% Discount Rate. C combines a $9 million cap and a 90% Discount Rate, selecting the lower candidate price without stacking. A’s verified denominator is 5 million shares. C includes promised options, but their schedule is missing; its documented base is 5 million shares. Each instrument’s relevant price formula and selection rule are expressly stipulated for this example.

A and B produce equal shares in S1 for different reasons. At a $3.00 financing price, with unchanged denominators, A remains at $1.60 while B converts at $2.40, producing approximately 166,667 shares. They are not economically interchangeable.

C’s displayed output assumes no additional qualifying promises; it is not a verified result. If later evidence establishes 500,000 additional qualifying shares, its cap price becomes approximately $1.6364, below the $1.80 discount price, producing approximately 244,444 shares. This sensitivity does not establish that those options exist. The company should request evidence before relying on C’s conversion figure. Calculations retain full precision; displayed shares are illustrative, not final issuance instructions.

Common mistakes

• Sorting by cap alone. Compare scenario outputs using instrument-specific denominators.
• Confusing rate with discount. Preserve the rate and calculate the reduction separately.
• Automatically stacking benefits. Follow the selection clause; do not discount a cap price without support.
• Using one capitalization total throughout. Reconcile each definition, including pool and convertible treatment.
• Treating missing side letters as nonexistent. Obtain custodian confirmation and keep affected results conditional.

Final quality check

Before circulation, confirm:

• Every operative SAFE and amendment has a stable ID and verified status.
• Caps, rates, formulas, and selection rules have checked source citations.
• Discount rates and economic discounts are separately labeled.
• Denominators reconcile to dated records, with exclusions explained.
• Scenario formulas have an independent arithmetic check and disclosed rounding.
• Conversion shares remain distinct from participation investments and final ownership.
• Open issues are resolved with evidence or assigned with an explicit reliance limitation.

Frequently asked questions

Is a lower cap always worse for the company?

No. Compare purchase amounts, denominators, discounts, and selection rules under shared assumptions. Resulting shares are more informative than cap amounts alone; ownership analysis also requires the complete post-financing capitalization.

Does an 80% Discount Rate mean an 80% reduction?

Not when the clause multiplies financing price by 80%; that means a 20% reduction. Verify the actual formula, as illustrated by CapCO2 Exhibit A §2. (sec.gov)

Can pre-money and post-money SAFEs share one table?

Yes. Label each basis and preserve separate denominator calculations. The table organizes evidence; it does not make differently defined caps directly comparable or justify a common ownership shortcut.

What if an MFN election could change terms?

Identify the clause, potentially relevant later issuance, and notice, election, or amendment evidence. Model alternatives conditionally. Do not replace operative economics merely because another investor received different terms.
