Many small businesses need money to grow and operate. They use two main ways to get money: convertible notes and SAFE (Simple Agreement for Future Equity) agreements. Both help companies raise funds, but they work differently. Convertible notes are loans that can turn into shares of stock later. SAFE agreements allow investors to get shares of stock in the future without a set price. Understanding SAFE Note Vs. Convertible Note and how these financing tools work is very important for business owners looking for funding.

What are the difference between SAFE Note Vs Convertible Note
| Feature | SAFE Note | Convertible Note |
| Definition | A Simple Agreement for Future Equity (SAFE) is an agreement that provides rights to investors to purchase company stock in future equity rounds without specifying the exact price per share at the time of the initial investment. | A Convertible Note is a form of short-term debt that converts into equity, typically in conjunction with a future financing round. |
| Structure | Equity agreement | Debt instrument that converts to equity |
| Repayment Obligation | No repayment obligation | Has a repayment obligation unless converted |
| Maturity Date | Typically no maturity date | Has a maturity date (e.g., 18-24 months) |
| Interest Rate | No interest rate | Generally has an interest rate (e.g., 5-8%) |
| Conversion Trigger | Conversion into equity is triggered by a future equity financing round or liquidity event | Converts to equity at a future financing round or at maturity if not repaid |
| Discount Rate | Often includes a discount rate on future equity price | Often includes a discount rate on future equity price |
| Equity Conversion | Converts into preferred stock | Converts into preferred stock or common stock |
| Negotiation Complexity | Typically simpler and quicker to negotiate | Can be more complex and time-consuming to negotiate |
| Investor Risk | Higher risk, no fixed return, dependent on future equity events | Lower risk due to debt nature and interest accrual |
| Dilution Impact | Can lead to significant dilution if company valuation grows significantly before conversion | Potentially less dilution due to interest accrual but depends on conversion terms |
| Investor Return | Dependent on company’s future equity events | Potentially more secure return due to debt structure and interest |
What is a Convertible Note?
A convertible note is a kind of temporary loan given to startups by investors. The investors expect that their loan will change into shares of the company later on. It works like a regular loan with an interest rate and due date. However, instead of getting the money back, the loan gets turned into stocks of the company when a certain event happens, usually when the company receives more funds from investors. The loan changes into company shares at that point.
Example of a Convertible Note
Suppose an angel investor provides a startup with $50,000 using a convertible note that has the following terms:
- 20% discount
- 6% interest annually
- Automatic conversion of the note after a funding round of $1 million
If the initial share price were $2, then due to the 20% discount, the startup’s shares could be acquired at $1.6 by the investor. Furthermore, interest accrues over time thereby increasing the count of shares when converted.

What is a SAFE Note?
An investor puts money into a company by buying a SAFE (Simple Agreement for Future Equity) note. This note gives the investor the right to get shares of the company in the future. A SAFE note is different from other types of debt like convertible notes. There are no interest rates or due dates with a SAFE note. Instead, the investor gets a promise that they will receive stock in the company at a later time. In exchange for giving money to the company now, the investor will get shares of stock later on.
Example of a SAFE Note
Suppose the fixed-investment of $50,000 were put up by our investor in another SAFEs and the SAFE were to have a discount rate of 20% and valuation cap of $2 million. If a Series A financing round is held by the startup with a $5 million valuation and a share price of $5 per share, the conversion of the investor’s SAFE notes would be:
- If the discount rate improves, $50,000 will change to equity at $4 per share (20% less than $5).
- If the valuation cap improves, $50,000 will change to equity at a price determined by the $2 million cap.
Key Differences Between SAFE & Convertible Note
1. Under Legal Structure: Convertible notes are debts that acquire interest and need to be paid back by a specific time; on the other hand, SAFE notes do not have any debt, interest or maturity provisions since they are equities.
2. Valuation: Convertible notes usually come with predetermined valuation caps or conversion prices; on the contrary, valuation of SAFE notes is deferred until some subsequent financing round.
3. Maturity and interest: Unlike SAFE notes, convertible notes attract interest over time besides having set maturity dates for repayment or conversion into equity.
4. Investor Protection: Convertible notes provide for more traditional investor protections like interest accrual, maturity dates among others whereas SAFE only rely on valuation caps alongside discount rates.
When to Use a SAFE Note
Startups in their initial stages often look for an easy way to raise funds without getting into complex valuation discussions. This is where SAFE notes come into play. SAFE stands for Simple Agreement for Future Equity. These notes are a common choice for early-stage companies that haven’t secured substantial funding yet.
They provide a straightforward path to gather investments while deferring the valuation conversations until a later stage. By that time, the startup is likely to have gained more traction, making it easier to assess its true worth accurately. The SAFE note’s appeal lies in its simplicity and flexibility, allowing young businesses to focus on growth and development before tackling the intricate valuation process.
When to Use a Convertible Note
Convertible notes are usually chosen by startups that have already obtained some funding and understand their value better. They give investors more regular protections and may be liked by investors seeking more certainty and safeguards. Furthermore, convertible notes may work better for startups needing to raise larger amounts of money. Startups at a more mature stage often favor convertible notes because they offer added security for investors.
This type of financing has well-defined terms and conditions that aim to protect the interests of both the startup and its investors. Convertible notes have clear guidelines on how the investment will convert into equity shares of the company at a future date, usually during the next major funding round. This conversion mechanism gives investors the opportunity to become shareholders in the startup, with their initial investment serving as the basis for their equity stake

Final Words
When startups need to raise money, they often use two special types of investment agreements called SAFE notes and convertible notes. A SAFE note is a simple contract that lets investors give money to a startup without immediately deciding how much the company is worth.The investor’s money converts into shares later, usually when the startup raises more money from other investors. A convertible note is more like a loan.
SAFE notes and convertible notes are different ways for startups to get money from investors. SAFE notes are easier and avoid tricky discussions about the startup’s value at an early stage. However, convertible notes protect investors more by acting like a loan with interest.
Convertible notes and SAFE notes are unique and cannot be converted into one another. However, startups can raise money through different fundraising rounds using either of them. For instance, a company could issue convertible notes in its seed round but opt for SAFE agreements during subsequent stages if investors prefer them.
If a startup crashes before the notes turn into equity, SAFE note holders generally don’t have any rights to the company’s assets because they aren’t viewed as debt instruments. However, depending upon the particular terms of the note, convertible note holders might be seen as creditors and could have claims.
Convertible notes do not always convert into equity. If the conversion conditions are not met or the maturity date is reached without conversion, the notes may need to be repaid or renegotiated.
The SAFE (Simple Agreement for Future Equity) agreement is a financing contract used by startups to raise capital. It allows investors to provide funds in exchange for the right to acquire equity at a later date, typically during a future equity financing round or liquidation event.
