Question & Answer
How Do Convertible Notes Work?
Investing in early-stage companies comes with a fundamental challenge – how do you determine valuation when there’s little to no revenue? Enter convertible notes, a flexible financing instrument that allows investors to defer valuation discussions while still securing equity upside.
Convertible notes function as a bridge between debt and equity. They start as loans but have the potential to convert into equity at a later stage, usually when the company raises a priced round. This structure makes them a go-to tool in venture capital, especially for seed-stage investments where valuation uncertainty is high.
What Is a Convertible Note?
A convertible note is essentially a short-term loan given to a startup by an investor. Unlike a traditional loan, it doesn’t get repaid in cash – instead, it converts into equity when certain conditions are met. This conversion usually happens during the next funding round when a formal valuation is established.
Why do investors and founders like this structure? Because it postpones the debate over valuation, allowing the company to grow before setting a price on its shares. It also speeds up funding rounds since negotiations focus on terms rather than a fixed valuation.
Key Terms in a Convertible Note
Convertible notes aren’t just simple IOUs – they come with structured terms that define how and when they convert.
- Conversion Trigger – The event that converts the note into equity, typically a qualified financing round where a set amount of capital is raised.
- Discount Rate – Investors receive a discount (often 10-30%) on the share price during the conversion, rewarding them for their early risk.
- Valuation Cap – A ceiling on the valuation at which the note converts, ensuring early investors get equity at a reasonable price even if the company grows rapidly.
- Interest Rate – Since it starts as debt, a convertible note may accrue interest, though this is usually added to the principal and converted into equity rather than paid out in cash.
- Maturity Date – The deadline by which the note must either convert into equity or be repaid. If a startup doesn’t raise a qualifying round, investors may negotiate alternative terms or demand repayment.
Why Investors Use Convertible Notes
For investors, convertible notes offer a way to get in early without locking into an uncertain valuation. They provide downside protection, as the investment starts as debt, while still capturing upside potential through conversion into equity.
They are particularly useful in:
- Seed rounds where valuation is unclear but momentum is strong.
- Bridge financing between larger funding rounds.
- Situations where investors want early exposure but are waiting for a lead investor to set a valuation.
Potential Risks and Downsides
While convertible notes provide flexibility, they aren’t without risks. For investors, the biggest concern is what happens if the startup never raises a priced round. If there’s no conversion event, the note either needs to be repaid or renegotiated, neither of which is ideal.
For founders, heavy reliance on convertible notes can create problems in future funding rounds. If too many notes convert at once, early-stage investors may end up with a significant portion of the cap table, making later financing rounds more difficult.
Additionally, unclear conversion terms can lead to misalignment. A valuation cap that is too low may overly dilute founders, while a high cap reduces early investors’ upside.
Structuring Convertible Notes Effectively
The best convertible notes are structured with fairness in mind. Investors want downside protection while ensuring they benefit from the startup’s success. Founders want to raise capital without giving away too much equity too soon.
Negotiating the right balance between the discount rate, valuation cap, and maturity terms is critical. Investors should also be mindful of stacking multiple notes across different rounds, as excessive dilution can occur when multiple notes convert at different terms.
Convertible notes remain one of the most effective tools in venture capital for early-stage investing. They provide speed, flexibility, and a way to defer difficult valuation conversations until more data is available.
In Deal Structuring, I break down real-world scenarios where convertible notes have been used successfully – and where they’ve gone wrong. Like any financial instrument, they are only as good as the terms negotiated. When structured properly, they offer a win-win for both investors and founders, providing capital to fuel growth while ensuring early backers are rewarded for their risk.
