Convertible notes in venture capital are a type of financing that can be a game-changer for startups. They're essentially a loan that can be converted into equity at a later date, providing flexibility for both investors and founders.
A key aspect of convertible notes is that they don't have a fixed interest rate, unlike traditional loans. This is because the conversion rate is determined at a later stage, often when the startup raises a new round of funding.
As a result, convertible notes can be a more attractive option for startups that are still in the early stages of growth. They allow founders to secure funding without giving up too much equity upfront, which can be a major advantage in the startup world.
The conversion rate of a convertible note is typically determined by the next round of funding, which can be a Series A round or later. This means that the conversion rate is tied to the valuation of the startup at that point in time.

What is a Convertible Note?
A convertible note is a type of financing instrument that allows investors to lend money to startups in exchange for equity in the company.
It's essentially a loan with a twist, as the principal amount can be converted into equity at a later date, usually during a future funding round.
Convertible notes are often used by startups that are still in the early stages of development, as they provide a flexible and low-risk way to raise capital.
The note's principal amount and interest rate are typically fixed, but the conversion price is tied to the next round of financing.
This means that if the startup raises more capital at a higher valuation, the investor's conversion price will be lower, making their equity more valuable.
Convertible notes can be a good option for startups that are not yet ready for a traditional equity investment, but still need to raise capital to grow their business.

Key Components
A convertible note is a type of financing that can be complex, but understanding its key components can make all the difference.
The discount is a key characteristic that rewards early investors for taking larger risks than later investors by offering them shares at a cheaper price than Series A investors.
Convertible debt notes contain an issuance date, interest rate, and maturity date, but repayment is with equity, not cash.
The valuation cap is another key feature that rewards early investors for their disproportionate risk by setting a maximum value of the company when Series A closes.
Early investors have the option to choose between the discount or cap conversion, with the conversion price being the lower of the two methods that results in more shares issued to the early investor.
A convertible note typically includes the following key elements: issuance date, interest rate, maturity date, discount, valuation cap, and the option to choose between the discount or cap conversion.

Conversion Provisions
A convertible note's primary goal is to convert into equity eventually, typically triggered by an equity investment surpassing a predetermined threshold, also known as qualified financing.
In most cases, a convertible note will automatically convert to stock at a predetermined value on the maturity date if no qualified financing occurs.
Convertible notes offer holders a discount on the price per share of the startup capital, in addition to receiving credit for their initial amount and interest charges.
Advantages and Disadvantages
Issuing a convertible note can be a smart move for startups, especially those in the seed stage. It allows them to postpone valuing themselves, which can be a relief when they haven't had much time to gain traction with their product and sales.
One of the benefits of convertible notes is that they don't grant any power to investors, which is a crucial aspect for many startups. This means investors who purchase preferred stock typically acquire some necessary control rights, such as a shareholder vote and the ability to veto certain corporate decisions.

One of the biggest advantages of a convertible note is that it allows a company to postpone valuing itself, which is especially appealing to seed-stage businesses that haven't gained significant traction yet.
Issuing a convertible note doesn't grant any power to investors, unlike preferred stock, which can come with control rights and veto power over corporate decisions.
A convertible note can be completed quickly, with a business able to finalize a round in just a day or two, with legal fees ranging from $1,500 to $2,000.
This speed and accessibility is a major advantage, especially for entrepreneurs who need to break through the impasse that can occur when investors wait to see who else will invest.
Here are some key benefits of convertible notes:
- Postpones valuation of the company
- No power is granted to investors
- Quick and accessible, with low legal fees
- Accelerates the closing of transactions
Disadvantages

When considering convertible notes, it's essential to weigh the advantages against the disadvantages.
One of the significant drawbacks is that note holders sacrifice certain rights given to traditional shareholders. These rights include voting rights, control rights, pro-rata rights, and a say in the company's liquidation.
This lack of control can be a major turn-off for potential investors, who may prefer to have a direct equity stake in the company.
Note holders also have minimal control over their investments until the conversion occurs, which can be a significant drawback.
The fact that future investors would determine the value of their investments and they would not be a part of this arrangement can be a deterrent for many investors.
Another disadvantage of convertible notes is that note holders don't start counting down to making long-term capital gains until the conversion date. This is in contrast to traditional shareholders, who can start counting down as soon as a share is issued.

Debt Components
Convertible debt, also known as a convertible note, typically includes a discount and a cap to compensate investors for taking on risk.
The discount is a percentage off the valuation of your startup, often around 20%, which protects the investor's investment if the startup valuation is close to or exceeds the cap.
A cap, on the other hand, is the maximum valuation at which the convertible debt can be converted to equity, and it's essential to understand how the cap works to maximize returns on investment.

Interest
Interest is earned on convertible debt investments, equivalent to other convertible debt investments.
The interest is frequently compounded, meaning the amount owed to the investor increases over time.
Some seed investors include an interest rate in their convertible debt to protect themselves against delays in startup valuation.
An interest rate can ensure a return on their investment, which is especially important for investors who need to see a return on their investment.

If you haven't offered series A stock by the maturity date, the convertible debt will begin accruing interest at a rate set in the original contract.
For example, if the interest rate is 1 percent, you would owe the investor $250 for every $25,000 in convertible debt.
This interest is added to the original amount of the convertible debt, so if you offered series A stock in the eighth month after the issuance date, the original convertible debt would be worth $25,250.

Maturity Date
Convertible notes have a maturity date, after which the company needs to repay the due and unpaid amount if the notes haven’t already been converted to stock.
Most startups don't have the funds to repay the investor, so they try to raise a Series A round before the maturity date.
The maturity date on a convertible note is the "times up" date, if a startup doesn’t manage to raise a Series A, they have to repay the investor, interest included.
Take a look at this: Seed Investor
Repaying the investor is a priority, as it's better to repay the debt than to risk defaulting and damaging your relationship with the investor.
With most convertible debt, you will repay the investment by converting the entire value to stock, but some investors may also include language that obligates you to pay back a certain percentage of the original investment as cash and the remainder as stock.

Debt Components
Convertible debt typically comes with a discount and a cap, which are essential components that make it desirable to early investors.
The discount gives the investor a percentage off the startup's valuation when the note converts to equity, protecting their investment in case the startup valuation is close to or exceeds the cap.
A cap is an upper limit on the price at which notes convert into equity, putting an upper limit on the investor's potential return.
An uncapped note has no valuation cap, which can put the interests of the startup at odds with the interest of the investor.

Interest on convertible debt is typically compounded rather than paid out in cash, increasing the amount owed to the investor over time.
Some seed investors include an interest rate in their convertible debt, which protects them against delays in startup valuation and ensures a return on their investment.
The interest rate is usually set in the original contract and accrues after the maturity date, adding to the original amount of the convertible debt.
The maturity date is the deadline for repaying the due and unpaid amount if the notes haven’t already been converted to stock.
Most convertible debt is repaid by converting the entire value to stock, but some investors may also include language that obligates the startup to pay back a certain percentage of the original investment as cash and the remainder as stock.

Cap
A valuation cap is a critical component of convertible notes, setting a hard cap on the price determined for noteholders. This cap is a guarantee for the investor, ensuring they won't be diluted by a high valuation in a subsequent round of equity funding.
The cap is calculated using the formula: Cap-Based Stock Purchase Price = Share Price X (Cap Amount / Series A Valuation). In Example 2, the cap is set at $10 million, and the Series A valuation is $20 million, resulting in a cap-based stock purchase price of $2.50 per share.
A cap-based stock purchase price of $2.50 per share is significantly lower than the $5 per share share price, giving the investor a better return on investment. In the example, the investor purchases 20,000 shares, with a real market value of $100,000, resulting in a return on investment (ROI) of $50,000.
The cap-based stock purchase price is not the only benefit for the investor; they also have the option to choose between the discount and the cap. As seen in Example 3, the cap will often offer the highest ROI, making it the better option for the investor.
In Example 4, an uncapped note is compared to a note with a valuation cap. While an uncapped note appears to favor the startup, it ultimately puts the interests of the startup at odds with the interest of the investor, which is bad for everyone.

Safes: Equity or Debt?
SAFES are neither equity nor debt, but rather an option to purchase equity at a future date, typically during a qualified funding round.
They're often used as a seed funding instrument, ideal for early-stage startups with a focus on rapid growth, allowing you to raise capital quickly and defer valuation discussions until later.
One of the key benefits of SAFES is that they offer investors the potential for a lower purchase price on equity if the company takes off, but they also provide less control and potential return compared to other options.
Here's a comparison of SAFES, equity, and convertible notes to help you understand the differences:
Ultimately, the choice between SAFES, equity, and convertible notes depends on your company's specific needs and risk tolerance.
Frequently Asked Questions
