The Simple Agreement for Future Equity, or SAFE, was launched in 2013. It was developed by Y Combinator as a novel funding tool for startups. In contrast to traditional funding, SAFEs aren’t loans.
They don’t accumulate interest and they lack a fixed repayment date. Instead, SAFEs offer investors rights to future equity. These become actionable at certain events like funding rounds or company takeovers.
This setup allows startups to get needed funds without immediately giving up ownership. Thus, it stands as a flexible and attractive choice for both startups and investors in the early-stage funding landscape.
Introduction to Simple Agreement for Future Equity
A Simple Agreement for Future Equity (SAFE) grants investors rights to future shares in a startup upon specific events. Y Combinator introduced SAFEs in 2013, revolutionizing startup financing. They offer simplicity and flexibility, differing from convertible notes by not accruing interest or having maturity dates. This arrangement benefits founders significantly in early financing stages.
SAFES attract new ventures aiming to raise funds without sacrificing equity. They convert into equity at later dates, allowing startups to keep control.
This method lets founders focus on growth rather than debt or complex equity models. It’s an innovative way to secure funds while maintaining a startup’s operations integrity.
Valuation caps and discount rates are key features of SAFEs.
Valuation caps prevent early investors from losing out as company valuations rise. Discounts, ranging from 5% to 30%, reward early investors with a price reduction in future rounds. These features make SAFEs an appealing option for first-time investors.
Feature | Description |
---|---|
Valuation Cap | Sets a maximum on the company’s valuation, ensuring fair share prices for early backers. |
Discount Rate | Offers 5% to 30% discounts on future share prices, compensating for early risks. |
Employee Stock Options | Equity compensation packages attracting and retaining talent, aligning with SAFE’s structure. |
Investor Rights | Lacks immediate ownership or voting rights, offering high potential rewards. |
Most favored nation (MFN) clauses in SAFEs let early backers secure terms from later rounds, maintaining uniform terms. This protects early investors’ interests and encourages more investment. It’s important to comply with U.S. Securities and Exchange Commission rules when converting to equity, ensuring legal compliance and investor safety.
In conclusion, SAFEs provide a straightforward way for startups to get funding, prioritizing equity preservation. They offer beneficial terms for both founders and investors, streamlining the capital-raising process.

How SAFEs Work
Since 2013, Simple Agreements for Future Equity (SAFEs) have significantly influenced startup funding, backed by the renowned accelerator Y Combinator. As an effective alternative to convertible debt, they allow startups to gain early funding minus traditional equity financing hurdles.
Origin and Popularity
Initiated by Y Combinator, SAFEs simplify the fundraising process. Their ease and adaptability have made them more favored than traditional methods. The absence of fixed maturity dates and interest frees startups from typical debt constraints.
Additionally, the 2018 introduction of post-money SAFEs has enhanced their popularity by simplifying valuation and ownership calculations.
Triggering Events
SAFEs are unique because they convert to equity only after specific events. Events like new funding rounds, acquisitions, or the company closing lead to conversion. The terms set a cap on valuation and offer discounts, favoring early investors during future financings.
This model postpones equity conversion, syncing investor rewards with the company’s growth.
Differences from Traditional Financing
In contrast to standard equity deals, SAFEs don’t immediately provide ownership or voting rights. They instead promise future equity, typically at a discount, once the company proves its worth.
They avoid interest and due dates, reducing early-stage financial pressure on startups. The approach marries conversion conditions with significant milestones, helping both startups and their financiers.
Benefits of Using SAFEs
Since their inception by Y Combinator in 2013, Simple Agreement for Future Equity (SAFE) agreements have become extremely popular. They present compelling benefits for startups and investors alike, streamlining the fundraising phase. T
he process becomes less complicated, immediate equity dilution is minimized, and discussions about the company’s valuation can be postponed. Let’s delve into the specific advantages for each party.
For Startups
- Simplicity and Efficiency: SAFE agreements are straightforward and economical, reducing legal fees and administrative burdens for startups seeking funding.
- Deferral of Valuation: By delaying valuation discussions, startups can achieve fair-market valuations later, avoiding early equity dilution.
- Non-Debt Nature: As non-debt financial instruments, SAFEs give startups flexibility without the worry of repayment deadlines.
- Customizable Terms: Startups can tailor the terms, like discount rates and caps, to suit investor preferences and secure beneficial agreements.
- Retained Ownership: Using SAFEs for initial funding lets founders and early investors keep their ownership stakes longer, by delaying equity dilution.
- Industry Contacts and Mentorship: SAFEs can connect startups with essential mentorship and industry contacts, enhancing their growth potential.
For Investors
- Investment Entry Point: SAFEs provide a predefined path into promising startups, allowing conversion of funds into equity in future rounds.
- Discounted Equity Purchase: This arrangement offers equity at below-future-market prices, granting investors favorable financial terms.
- Valuation Caps: Valuation caps ensure investors’ money converts into equity at a maximum price, offering investment protection.
- Pro-Rata Rights: Features like pro-rata rights enable investors to maintain or grow their stake in subsequent financing phases.
- Aligned Incentives: Through SAFEs, the interests of investors and founders converge, fostering mutual success in growing the company’s value.
SAFEs represent a versatile and straightforward mechanism for navigating the complexities of startup funding. They afford founders the leeway to focus on growth without the immediate threat of losing equity.
Simultaneously, they provide investors with secure, advantageous, and potentially profitable terms of engagement.

Critical Components of a SAFE
Both startups and investors must grasp the essentials of a Simple Agreement for Future Equity (SAFE). The valuation cap and the discount rate are the terms’ crucial aspects. They significantly influence the agreement’s structure.
Valuation Cap
An investor’s money converts into equity at a maximum valuation set by the valuation cap. This benefits early investors by guaranteeing a more substantial equity share in later funding rounds. Consequently, if the startup secures investments at a higher valuation, early investors use the capped valuation for conversion. This assures them a larger slice of the equity pie.
- Seed-stage startups often see valuation caps between $3M and $10M.
- Valuation caps ensure balanced valuations, protecting both founders and investors.
Discount Rate
The discount rate lets investors buy shares at below future investor prices. This acknowledges the greater risk early backers take. Consequently, investing early means obtaining a bigger equity share later, thanks to this discount.
- Investors typically enjoy a 10-20% price cut when turning SAFEs into equity.
- Such discounts favor initial backers with better terms than those offered to subsequent investors.
Component | Description | Typical Terms |
---|---|---|
Valuation Cap | Maximum valuation for equity conversion | $3M – $10M for seed-stage startups |
Discount Rate | Reduced share price for early investors | 10-20% discount |
The valuation cap and discount rate are vital in SAFEs. They ensure fair equity distribution and shield early investors’ interests.
Simultaneously, they decrease startups’ financial burdens in early funding phases. A deep understanding of these elements is crucial for anyone involved in startup finance.
Comparison of SAFEs and Other Financing Instruments
When we look at SAFEs alongside other initial-stage financial routes like convertible notes, loans, and direct equity stakes, we see their standout feature as non-debt vehicles.
They’re essentially equity warrants without the burdens of interest or debt obligation found in other financial instruments. This difference streamlines the investment procedure, aids in managing the cap table more efficiently, and may offer investors tax benefits.
A comparative glance at SAFEs against other widely used financial tools is shown below:
Criteria | SAFEs | Convertible Notes | Loans | Equity Financing |
---|---|---|---|---|
Repayment Obligation | No | Yes, at maturity | Yes | No |
Interest Rate | No | Yes, paid in equity | Yes | No |
Valuation Cap | Yes | Yes | No | Based on market |
Complexity | Low | Moderate to High | High | Moderate |
Maturity Date | No | Yes | Yes | No |
Position in Dissolution | Priority to repay investors before common shareholders | Priority to repay investors before common shareholders | Priority to repay loan | Equity holders last |
Ownership Dilution | Yes, upon conversion | Yes, upon conversion | No | Yes |
Though SAFEs and convertible notes show clear differences, each offers a unique route to financing for startups at the seed or pre-seed stages. SAFEs eliminate debt obligations and interest, simplifying the funding process.
Convertible notes, on the other hand, balance debt with equity features through interest and future equity purchase discounts.
Types of SAFE Agreements
There’s a range of SAFEs available, each designed to meet different startup needs.
Common SAFE Variations
Startups and investors benefit from various SAFE types, each addressing distinct valuation and discount scenarios. The main types include:
- Valuation Cap, No Discount: Fixes the company’s valuation for equity conversion without a discount.
- Valuation Cap with Discount: Offers a valuation cap and a discount, ensuring a lower conversion price either way.
- No Valuation Cap, Discount: Provides a discount on future equity rounds without capping the valuation.
- No Valuation Cap, No Discount: Simple and straightforward; it neither caps the valuation nor offers a discount.
SAFE Type | Valuation Cap | Discount Rate | Description |
---|---|---|---|
Valuation Cap, No Discount | Yes | No | Sets a cap on the company’s valuation for conversion, no discount provided. |
Valuation Cap with Discount | Yes | Yes | Includes a valuation cap and a discount on the share price at conversion. |
No Valuation Cap, Discount | No | Yes | Offers a discount on future equity rounds, no valuation cap. |
No Valuation Cap, No Discount | No | No | Neither a valuation cap nor a discount is provided. |
Pre-Money vs. Post-Money SAFEs
When startups raise funds using Simple Agreements for Future Equity (SAFEs), they must decide between pre-money and post-money structures. These two types differ significantly in how they impact valuation and equity distribution.
Pre-Money SAFEs
Pre-money SAFEs calculate valuation caps or discounts without including the SAFE investments already raised. This structure benefits founders by reducing their dilution. For instance, if a startup sets a pre-money valuation cap of $5 million and then raises $1 million via SAFEs, the total valuation cap remains $5 million.
According to Y Combinator, pre-money SAFEs offer clarity on the maximum company valuation before new investments, thus keeping founder ownership higher by excluding the invested SAFE amounts from the cap calculation.
Post-Money SAFEs
Post-money SAFEs offer a more transparent approach by including SAFE investments in the valuation calculations. This means the valuation cap accounts for the total amount of SAFE investments. For example, if a startup has a post-money valuation cap of $5 million and raises $1 million via SAFEs, the new valuation cap becomes $6 million.
This structure provides investors with a clearer picture of their eventual ownership percentage after the SAFE converts into equity. The NVCA Model Legal Documents highlight that post-money SAFEs make it easier to predict dilution and ownership stakes, aiding in transparent negotiations between founders and investors.
Legal and Regulatory Considerations of SAFEs
Understanding the legal and regulatory aspects of Simple Agreement for Future Equity (SAFE) agreements is critical for startups and investors.
SAFEs have been adopted by major startups like Airbnb and Uber, reflecting their importance in today’s business environment. Here’s an in-depth look at the key legal considerations:
Compliance with Securities Laws
SAFEs are considered securities, and their issuance and conversion must comply with the Securities and Exchange Commission (SEC) regulations. This compliance includes necessary filings under Regulation D, which exempts private companies from registering with the SEC when offering securities.
Companies must ensure they meet both state and federal securities laws to avoid legal repercussions.
- Regulation D Filings: Regulation D includes rules for offering and selling securities without having to register with the SEC. Rule 506(b) and Rule 506(c) are commonly used exemptions. In 2024, the SEC reported an increase in Regulation D filings, highlighting the growing use of private securities offerings .
- Tax Implications: Understanding the tax implications of SAFEs is essential, especially since they do not generate interest or dividends like traditional debt instruments. This non-debt classification can affect how both the company and the investors report these instruments for tax purposes .
Investor Rights and Protections
Investor rights in SAFEs are generally limited until the conversion to equity. It’s crucial for investors to understand their rights regarding repurchase clauses and outcomes in dissolution scenarios.
- Repurchase Clauses: These clauses determine under what conditions the company can repurchase the SAFE from the investor. It’s vital to clarify these terms upfront to avoid disputes.
- Dissolution Outcomes: In the event of a company dissolution, investors need to know how their SAFEs will be treated. Typically, SAFEs convert to equity before any remaining assets are distributed to shareholders.
Non-Debt Classification
SAFEs are classified as non-debt instruments, simplifying their structure. They do not include repayment promises or interest rates, differentiating them from traditional loans.
- Simplicity and Flexibility: The non-debt nature of SAFEs makes them simpler and more flexible for startups, as they do not impose a debt burden on the company. This feature has contributed to their widespread adoption.
Conversion Terms
The terms of conversion are fundamental to determining the equity investors will receive. These terms include valuation caps, discount rates, and the timing of conversion, which can be triggered by equity financing, liquidity events, or dissolution.
- Valuation Caps and Discount Rates: These features provide a way for investors to convert their investment into equity at a favorable rate, which can be crucial during subsequent funding rounds.
- Trigger Events: Conversion is typically triggered by specific events such as subsequent equity financing, acquisition, or initial public offering (IPO). Understanding these triggers is essential for both startups and investors to plan their financial strategies effectively.
Case Study Example: Airbnb
Airbnb utilized SAFEs in its early fundraising rounds, which allowed the company to raise capital without the complexities of traditional equity financing. This approach provided flexibility and attracted a broad range of investors, setting a precedent for other startups to follow.

Risks of SAFEs
Simple Agreements for Future Equity (SAFEs) offer a streamlined method for early-stage fundraising, but they carry significant risks for both startups and investors.
These risks include overvaluation, ownership dilution, and uncertainty regarding liquidity events. Understanding these risks is crucial for navigating SAFEs effectively.
Overvaluation Risk
One of the primary risks for startups using SAFEs is the potential for overvaluation. If subsequent funding rounds do not materialize or specific milestones are not achieved, investors may not receive equity, leaving the startup without the necessary capital infusion.
This situation can jeopardize the company’s growth and sustainability.
- Market Volatility: In 2023, PitchBook reported that nearly 30% of startups faced down rounds or flat valuations due to market volatility, highlighting the risk of overvaluation.
- Funding Uncertainty: According to Crunchbase, approximately 25% of early-stage startups fail to secure follow-up funding within two years, posing a risk to SAFEs converting into equity.
Ownership Dilution
For founders, the conversion of SAFEs into equity during liquidity events can lead to significant ownership dilution. This dilution occurs when new shares are issued, reducing the percentage of ownership held by existing shareholders.
- Dilution Impact: A study by the Harvard Business Review found that early-stage companies often experience an average ownership dilution of 15-20% per funding round [Harvard Business Review, 2024].
- Negotiation of Terms: It’s vital to carefully negotiate terms such as valuation caps and discount rates to mitigate dilution. Founders must ensure that these terms align with their long-term ownership goals and financial strategies.
Uncertainty of Liquidity Events
For investors, the primary risk associated with SAFEs is the uncertainty surrounding liquidity events. SAFEs are designed to convert into equity upon specific triggering events such as additional funding rounds or acquisition. However, these events can be unpredictable and may take several years to materialize.
- Conversion Delays: A report by CB Insights indicated that it takes an average of 6-8 years for a startup to reach a liquidity event, with some companies taking over a decade to achieve this milestone.
- Valuation Caps: Valuation caps in SAFEs can become contentious during later funding rounds, potentially making the startup less attractive to new investors. Negotiating favorable terms that are attractive to all parties is essential.
Market and Regulatory Challenges
The dynamic nature of market conditions and evolving regulatory frameworks can also impact the effectiveness and risks associated with SAFEs.
- Regulatory Compliance: Adhering to SEC regulations and understanding the tax implications of SAFEs is complex. Non-compliance can lead to legal issues and financial penalties.
- Market Conditions: Fluctuating market conditions, as observed with the increased volatility in tech startups in 2023, can affect the attractiveness and conversion potential of SAFEs.
