Convertible Note
What Is a Convertible Note?
A short-term debt instrument that converts into equity, typically used by seed-stage startups to raise capital without establishing an immediate company valuation.
A convertible note is a popular financing vehicle for early-stage startups. It is structured as a loan (debt) but is designed to convert into equity (ownership) at a later date, usually when the company raises a larger round of funding, known as a priced round (e.g., Series A). Unlike standard loans, the intention is not for the startup to repay the principal and interest in cash. Instead, the outstanding balance is used to "buy" stock in the company at a discounted rate. The primary reason for using a convertible note is valuation—or the lack thereof. Valuing a brand-new company with no revenue or assets is difficult and often contentious. By using a convertible note, the founders and investors agree to kick the valuation can down the road to a future date when the company has more traction and metrics to support a concrete valuation. This speed and simplicity make it a go-to instrument for angel investing and seed rounds.
Key Takeaways
- A convertible note acts as a loan that automatically turns into shares of stock during a future financing round.
- It allows startups to delay placing a specific value on the company until it is more mature.
- Investors receive interest, which accrues and converts into additional equity rather than being paid in cash.
- Key terms include the valuation cap and the discount rate, which protect early investors.
- Convertible notes are simpler and faster to execute than a full equity round.
How Convertible Notes Work
When an investor purchases a convertible note, they give money to the startup. The note carries an interest rate, but unlike a bank loan, this interest isn't paid monthly. Instead, it accrues over time and is added to the principal amount at the time of conversion. The conversion event is typically triggered by a "qualified financing" round, where the company raises a specific amount of equity capital from new investors. At this point, the note holder's debt (principal plus accrued interest) converts into shares. To reward the angel investor for taking a risk earlier than the Series A investors, the note usually includes a "discount rate" (e.g., 20%) or a "valuation cap." The discount rate allows the note holder to buy shares at a lower price than the new investors. The valuation cap sets a maximum effective valuation for the conversion, ensuring that if the company's value skyrockets, the early investor still gets a significant chunk of equity proportional to their early risk.
Important Considerations
For founders, convertible notes are attractive because they are legally cheaper and faster to close than equity rounds. However, they are still debt. If the startup fails to raise the next round before the maturity date, the note becomes due. While investors rarely force a startup into bankruptcy over this, it can create significant leverage and negotiation issues. For investors, the valuation cap is critical. Without it, if the startup becomes a unicorn before the next round, the investor's small loan would convert into a tiny sliver of equity, despite the high risk they took. The interplay between the discount and the cap ensures the investor receives the better of the two deals (whichever results in more shares or a lower price per share).
Real-World Example: Seed Funding Scenario
An angel investor puts $50,000 into a startup via a convertible note with a 20% discount and a $5 million valuation cap. One year later, the startup raises a Series A round at a $10 million pre-money valuation with a share price of $1.00.
FAQs
A SAFE (Simple Agreement for Future Equity) is similar but is not a debt instrument. It has no maturity date and no interest rate, making it simpler and more founder-friendly. Convertible notes are actual debt with a maturity date and interest, offering slightly more protection to investors.
Most convertible notes have a clause for a change of control (acquisition). Typically, the investor gets to choose between receiving their principal back with a premium (e.g., 2x payout) or converting into equity at the valuation cap immediately prior to the sale.
Rarely. The interest usually accrues and is added to the principal balance, meaning the investor receives more shares upon conversion rather than cash payments.
This is a specific threshold defined in the note (e.g., raising $1 million in new equity) that automatically triggers the conversion of the note into shares. It ensures the note doesn't convert for trivial amounts of new investment.
Yes, and this is common. The investor usually gets to choose whichever method (cap or discount) results in a lower share price (more shares) at the time of conversion.
The Bottom Line
Convertible notes are a fundamental tool in the startup ecosystem, bridging the gap between an idea and a measurable business valuation. They balance the need for speed and capital for founders with the need for upside protection and reward for early investors. While simpler than equity rounds, the terms regarding caps and discounts can significantly impact future ownership stakes.
