This guide is designed to be your trusted companion as you navigate the world of Simple Agreements for Future Equity (SAFEs). We’ll demystify the intricacies of SAFEs, equipping you with the knowledge and confidence to negotiate with investors effectively. By the time you finish reading, you’ll have a solid understanding of this essential fundraising tool.

Decoding the Simple Agreement for Future Equity (SAFE)

A Simple Agreement for Future Equity (SAFE) is a straightforward contract used by startups and investors to streamline early-stage fundraising. Essentially, it grants investors the right to purchase shares in the company during a future priced funding round in exchange for their investment. Unlike traditional convertible notes, SAFEs are not debt instruments; they don’t accrue interest or have a fixed maturity date.
Pioneered by Y Combinator in 2013, SAFEs gained rapid adoption for their simplicity and founder-friendliness. Initially designed as “pre-money” agreements, the landscape evolved with larger funding rounds. This led to the introduction of the “post-money” SAFE in 2018, which has since become the industry standard.
The key difference lies in how ownership is calculated. Post-money SAFEs clearly define investor ownership percentages after accounting for all SAFE investments but before the next priced funding round, usually a Series A. This transparency is crucial for managing equity and dilution as the company grows.
Today, Y Combinator offers four main SAFE variations, each with its own set of terms:
SAFE: Valuation Cap, No Discount
SAFE: Discount, No Valuation Cap
SAFE: Valuation Cap and Discount (While removed from Y Combinator’s website, it remains in use).
SAFE: MFN, No Valuation Cap, No Discount

While these templates offer a starting point, investors and founders often tailor specific terms with legal guidance to best suit their individual needs.

Why Startups Love SAFEs


The startup community has enthusiastically embraced SAFEs for a number of reasons:
Speed and Simplicity:
SAFEs are remarkably concise and easy to understand, typically around six pages long. This simplicity translates to faster negotiations and a more streamlined, cost-effective investment process.
Founder-Friendly Terms:
Unlike convertible notes, SAFEs do not burden founders with interest payments, maturity dates, or the obligation to repay the principal if the company doesn’t reach a qualifying funding round. This allows founders to focus on building their businesses without the pressure of looming deadlines or debt repayment.
Flexibility in Fundraising:
SAFEs empower startups to raise capital incrementally. They can close deals with investors as soon as both parties are ready, allowing for a more flexible and efficient fundraising process, often referred to as “high-resolution fundraising.”
Focus on Growth:
By eliminating the complexities of traditional financing instruments, SAFEs free up valuable time and resources, allowing founders to concentrate on what matters most: building a successful company.
While SAFEs offer significant benefits to startups, it’s important to remember that they are not suitable for all investors. Investors seeking a guaranteed return or those uncomfortable with the risks inherent in early-stage investing may prefer alternative investment structures.

The Potential Downsides of SAFEs


While SAFEs offer significant advantages, it’s important to be aware of their potential drawbacks:
Absence of Equity Stakes:
It’s crucial to understand that SAFE investors don’t immediately receive equity in the company. They’re essentially holding a promise of future equity contingent upon specific events, like a qualified fundraising round. This lack of immediate equity means SAFE investors have limited rights and protections compared to traditional shareholders. If those triggering events never materialize, investors risk walking away empty-handed.
The Simplicity Trap:
The very simplicity that makes SAFEs attractive can also pose a risk. The ease of raising funds through SAFEs can sometimes lead founders to raise more capital than strategically necessary, without fully grasping the long-term implications for equity dilution. When the SAFEs eventually convert, founders may find themselves with a significantly smaller ownership stake than anticipated.
Careful planning, a solid understanding of future equity implications, and seeking legal counsel are essential to navigate these potential disadvantages effectively.

How SAFEs Convert into Equity


The key question for investors and founders alike: What happens to a SAFE when a company raises a priced funding round?
A SAFE outlines that an “equity financing” triggers conversion. This broadly refers to any future funding round where the company issues and sells preferred stock at a fixed valuation – essentially, any priced round, regardless of size.
Upon such an event, the SAFE investor’s investment converts into preferred shares, mirroring the same rights and privileges as the new investors participating in the priced round. This is a critical point for founders to grasp: when negotiating terms with new investors in a priced round, they’re simultaneously shaping the terms for their SAFE holders.
The exact number of shares a SAFE converts into depends on whether it includes elements like a discount or a valuation cap.
Get ready to crunch some numbers—it’s time to dive into the math behind SAFE conversions.

Decoding the SAFE Discount
Early-stage investments come with inherent risks, and the SAFE’s discount mechanism is designed to compensate investors for taking that leap of faith.
In simple terms, the discount grants SAFE investors the right to purchase shares in the future priced round at a lower price than new investors. The discount typically ranges from 5% to 30%, with 20% being the most common.
Here’s an example:
Imagine a SAFE with a 20% discount. If new investors purchase shares at $1 per share during a Series A round, SAFE investors would pay only $0.80 per share upon conversion. A higher discount translates to more equity for the SAFE investor.
Important Note:
The SAFE agreement clearly states the discount rate as a percentage less than 100%. So, you’ll see a 20% discount represented as “80%,” and a 10% discount as “90%.”
Beyond the Discount: The Valuation Cap
While the discount offers some protection, it might not be sufficient for rapidly growing companies. In such scenarios, investors often utilize a valuation cap alongside the discount to ensure their investment keeps pace with the company’s increasing value. We’ll explore the concept of the valuation cap in detail next.

Navigating Valuation Caps in SAFEs

The valuation cap is often the most heavily negotiated term in a SAFE agreement. Why? Because it sets the maximum price a SAFE investor will pay for their shares, regardless of the company’s actual valuation in a future priced round.
Understanding the Mechanics
Let’s say a SAFE has a valuation cap of $10 million. If the company later raises a Series A at a $20 million valuation, SAFE investors will essentially purchase shares at half the price of the new investors, giving them a significant advantage.
The SAFE agreement provides a formula to calculate the price per share (referred to as the “safe price”) using the valuation cap:
Safe Price = Valuation Cap / Company Capitalization
Importantly, the company capitalization includes not just existing shares but also all convertible securities like other SAFEs, convertible notes, and options.
Balancing Rewards and Dilution
Setting the right valuation cap is a delicate balancing act. While rewarding early investors for their risk is essential, founders must also protect themselves from excessive dilution. A low valuation cap can disproportionately favor SAFE investors, leaving founders with a significantly smaller ownership stake down the line.
Strategic Considerations for Founders
Don’t Confuse a Cap with a Valuation: A valuation cap is not a true reflection of the company’s current worth; it’s simply a ceiling on the price SAFE investors will pay in the future.
Project Realistically: Determine a valuation cap that reflects a reasonable projection of the company’s value at its next fundraising stage.
Consider Alternatives: If possible, try to negotiate SAFEs with a discount but no valuation cap. This rewards early investors without setting an artificial ceiling on the company’s future value.
Ultimately, finding the right balance between attracting early-stage investment and maintaining reasonable equity for founders is crucial.

Understanding Valuation Cap Scenarios: How SAFEs Convert

When a SAFE includes a valuation cap, there are three potential outcomes during conversion at a priced funding round:
Scenario 1: Valuation Cap Exceeds Priced Round Valuation
This scenario suggests the company raised a priced round at a valuation lower than the SAFE’s cap, which isn’t ideal for demonstrating growth. However, it simplifies the SAFE conversion. Investors either convert at the discount rate (if applicable) or at the same price as new investors if there’s no discount.
Scenario 2: Valuation Cap is Lower than Priced Round Valuation
This is the most common—and generally desirable—outcome. The company has secured a higher valuation in the priced round, signaling positive growth. SAFE investors benefit from their early investment by converting at the lower valuation cap, unless a discount rate results in an even more favorable price.
Scenario 3: Valuation Cap Matches Priced Round Valuation
In this scenario, the priced round valuation precisely matches the SAFE’s cap. SAFE investors convert at the same price as new investors, effectively nullifying any price advantage from the cap. If a discount is present, they’ll convert at the discounted price, as that would be more beneficial than the matching valuation.

Understanding Most Favored Nation (MFN) Clauses in SAFEs

An MFN clause in a SAFE provides early investors with a valuable safeguard—the right to match the most favorable terms offered to future SAFE investors. In essence, it ensures that early supporters aren’t disadvantaged if later investors strike a better deal.
How MFNs Work
Imagine an investor contributes $20,000 under an MFN-only SAFE (no cap or discount). Later, a new investor invests $2 million with a capped and discounted SAFE. The company must inform the initial investor about these new terms. If the first investor finds the later terms more advantageous, they can choose to amend their original SAFE to match.
Benefits and Drawbacks of MFNs
MFNs offer benefits like:
Investor Protection: They provide peace of mind to early investors, knowing their terms won’t be less favorable than those offered later.
Simplified Negotiations: MFNs can streamline early-stage fundraising by removing the complexities of negotiating a valuation cap.
However, MFNs have potential downsides:
Reduced Fundraising Flexibility: Offering increasingly favorable terms to later investors can deter future funding rounds and make negotiations more complex.
Potential for Disputes: Disagreements over MFN interpretations and amendments can strain founder-investor relationships and lead to legal disputes.

Strategic Considerations
MFN clauses can be valuable tools, but their inclusion should be carefully considered. Founders must weigh the benefits of investor protection against potential limitations on future fundraising flexibility.

Side Letters: Expanding the Scope of SAFEs


A side letter serves as an addendum to the main investment agreement, in this case, a SAFE. It allows investors and companies to customize certain terms or include additional provisions not covered in the standard SAFE template.
Pro Rata Rights: A Common Inclusion
The most common provision within a Y Combinator SAFE side letter is the inclusion of Pro Rata Rights. This grants SAFE investors the option, but not the obligation, to participate in future funding rounds to maintain their ownership percentage. It’s generally considered a balanced provision that benefits both founders and investors.
Beyond Pro Rata: Navigating Additional Terms
Occasionally, investors may attempt to introduce a range of additional rights and preferences into a side letter. Founders should always carefully review these terms with their legal counsel to fully comprehend their implications before agreeing.
Minimizing Side Letters: A Best Practice
While side letters offer customization, founders should strive to minimize their use whenever possible. Tracking and managing various side agreements can become unwieldy and create administrative burdens, especially as the company grows and undergoes multiple funding rounds.
