Founders love SAFEs because they’re fast, lightweight, and designed to get capital into a startup without the friction of a full priced equity round. But as we tell clients at Veritas Global, “simple” does not mean risk-free, and choosing the wrong SAFE structure can complicate future fundraising or misalign investor expectations.
In a prior article—“The Post-Money SAFE With a Discount” and “The Post-Money SAFE With a Valuation Cap” we broke down the fundamentals of how SAFEs convert, the nuances of the post-money model, and how these instruments shape dilution at the time of a priced round. If you haven’t read that one yet, it’s worth reviewing before diving into the variants.
Today’s article goes deeper. Y Combinator provides three versions of its post-money SAFE:
- Discount SAFE (no valuation cap)
- Valuation Cap SAFE (no discount)
- MFN SAFE (no cap, no discount, “most-favored-nations”)
Each version influences investor economics in different ways, and choosing among them requires founders to understand investor priorities, market conditions, and the startup’s stage of development.
Let’s break it down in a way that reflects market reality—and avoids costly surprises at your next priced round.
Understanding Why Investors Choose One SAFE Over Another
One of the biggest misconceptions is that there is a “best” SAFE. There isn’t. Each version “prices risk” differently, and each appeals to investors based on what they value most:
- Economics today → Discount SAFE
- Ownership certainty later → Valuation Cap SAFE
- Flexibility without overcommitting → MFN SAFE
Choosing correctly requires founders to balance fairness, dilution, and long-term fundraising strategy.
1. The Discount SAFE
For early-bet investors who want economic upside—without forcing a valuation too soon.
A Discount SAFE is ideal when both sides agree it is simply too early to value the company. Maybe the product is pre-launch. Maybe revenue is speculative. Maybe founders need fast money to reach a proof-point.
Here’s how it works:
At your next priced round, the SAFE converts at a discount to the Series Seed or Series A investors.
If your discount is 20%, the SAFE investor pays 80% of the Series A price.
But here’s the subtlety that founders routinely get wrong:
YC uses the term “Discount Rate” —not “discount percentage.”
If the investor receives a 20% discount,
the Discount Rate is 80%.
Meaning:
- 20% discount
- 80% Discount Rate
- SAFE converts at 80% of the priced-round share price
Get this wrong, and your cap table math will be wrong—and investors will not be amused.
The Discount SAFE is perfect when:
- No reasonable valuation can be agreed upon
- Investors want guaranteed upside for investing early
- Both parties believe later investors will set a more accurate valuation
It is not ideal if investors want ownership certainty or dilution protection. It simply offers an economic advantage—not a guaranteed percentage of your company.
2. The Valuation Cap SAFE
For investors who want clarity on the maximum price they might pay for equity.
A Valuation Cap SAFE is the most commonly used SAFE in venture financing today.
Rather than offering a discount, it sets a maximum valuation at which the SAFE can convert. This protects investors from “irrational” or unexpected jumps in your valuation at the priced round.
Example (simple, founder-friendly math)
- SAFE investment: $250,000
- Post-money valuation cap: $5,000,000
- Guaranteed minimum ownership: $250,000 / $5,000,000 = 5%
This matters because:
- If your priced round comes in at a higher valuation (say, $12M), the SAFE still converts at the $5M cap.
- If your priced round valuation is lower than the cap, the SAFE simply converts at that lower price.
This means:
SAFE investors get the better of:
- The valuation implied by the cap or
- The valuation set by the priced round
It guarantees investors won’t overpay.
It does not guarantee they will always receive a discount.
And it requires both sides to agree—prematurely—on a number that resembles a valuation.
This point creates tension for pre-revenue or concept-stage startups. Setting a cap too early may:
- Anchor expectations for future financing
- Over-dilute founders
- Create negotiating friction with future VCs
For founders planning multiple rounds, we often advise reviewing our article on valuation discipline: “Valuation, Investors and the Amount Raised” .
3. The MFN SAFE
Rarely used—but powerful in narrow circumstances.
The MFN (“Most-Favored Nations”) SAFE includes:
- No discount
- No valuation cap
- No preset economic advantage
Instead, it offers investors a simple promise:
If the company issues a future SAFE on better terms, the MFN Investor can amend theirs to match it.
the MFN investor can amend theirs to match it.
This structure is useful when:
- A very early investor wants to invest before formal fundraising
- The startup cannot set valuation expectations yet
- Both parties want to avoid negotiating economic terms prematurely
In practice, MFN SAFEs are uncommon—but they are sometimes used for:
- Friends-and-family investors
- Accelerators
- Small early checks where signaling is more important than pricing
This article pairs well with our analysis of investor protections, which explores how investor rights can shift over time:

How Founders Should Choose Among the Three SAFEs
Ask yourself what your investors value most:
If investors want economic upside, choose:
- Discount SAFE
If investors want ownership clarity, choose:
- Valuation Cap SAFE
If early supporters want flexibility without economics, choose:
- MFN SAFE
No SAFE is “founder friendly” or “investor friendly” in the abstract.
It’s all about aligning incentives with your stage, traction, and financing roadmap.
Founders planning sophisticated conversions, multiple SAFE rounds, or targeted dilution should also review our article on the post-money SAFE dilution effect, which explains how repeated SAFEs stack on the cap table.
Final Thoughts
SAFEs are fast, efficient, and powerful—but they are not interchangeable. Picking the wrong one (or filling it out incorrectly) can:
- Over-dilute founders
- Undervalue early investors
- Slower or complicate future fundraising
- Create cap table inconsistencies at the Series A
At Veritas Global, we help founders structure their early-stage capital raises with precision—whether you’re negotiating your first SAFE, running a multiple-SAFE strategy, or preparing for institutional VC.
