A convertible note is a short-term loan that converts into equity later.
It’s a fast, simple way for early-stage startups to raise money. Why? It skips the biggest hurdle in seed fundraising: agreeing on a valuation before you have real traction.
What a convertible note means for founders
Raising your first round is tough. You need cash to build, but investors want to know your company’s worth. That’s nearly impossible to pin down when you’re just a great idea.
This is the exact problem a convertible note solves. It lets you delay the tricky valuation conversation until a later funding round.
Think of it like this: an investor gives you cash now as a loan. But instead of getting paid back in dollars plus interest, their loan turns into ownership (equity) in your company.
This usually happens when you raise your first official "priced" round, like a Series A. The structure is popular for founders who need to move fast. It helps you avoid getting bogged down in valuation debates.
This tool is a critical part of fundraising. It impacts how you present your startup in your what is a pitch deck.
So what does this mean in practice?
- Speed: Close funding in weeks, not months. The legal documents are simpler than in a priced equity round.
- Lower cost: Simpler agreements mean lower legal fees. Founders often save $10,000–$30,000 compared to a priced round.
- Delayed valuation: You get cash to hit key milestones before locking in a valuation. This gives you a chance to earn a much higher one later.
Example
A founder needs to hire a key engineer now to finish their MVP. Instead of spending three months hashing out a priced round, they close a $250,000 convertible note in three weeks. They land the talent they need and keep building without missing a beat.
How a convertible note works
A convertible note might sound complex, but its lifecycle is simple. It has three parts: the loan, the growth period, and the conversion.
Let’s walk through the journey, from an investor’s cash to their equity.
The loan and growth period
Imagine you’re the founder of "ConnectSphere," a SaaS startup. You need $100,000 to hire your first engineer and build an MVP. An angel investor gives you that money via a convertible note.
They wire the $100,000, and the clock starts. For now, it’s a loan on your books. You use that cash to build, land users, and get traction.
You’ll also prepare your startup financial projections template for the next stage. This is the growth period where you prove your model works.
The trigger: the priced round
The note doesn’t stay a loan forever. It’s designed to convert into equity. This usually happens during a "triggering event," most often a priced round like your Series A.
This is when a new, larger investor (like a VC) leads a round where they formally value your company.
For ConnectSphere, let’s say a VC invests $2 million at a $10 million pre-money valuation. That priced round is the trigger. It starts the conversion process for your original angel investor.
The early investor’s loan now becomes shares in your company. But they get a better deal than the new VCs. It’s their reward for taking a risk on you early.
This visual shows the flow from loan to equity.
From debt to equity: the conversion
When the priced round happens, the key terms from the original note come into play. These are the valuation cap and discount rate.
These terms decide how many shares your early investor gets. The loan is wiped from your balance sheet, and your angel investor becomes a shareholder.
Example
An investor provides $100,000 as a loan. You use that cash to grow the company for 18 months. You then raise a Series A, which triggers the note’s conversion from debt into equity for that first investor.
Decoding key terms: valuation cap and discount
When negotiating a convertible note, two terms dominate: the valuation cap and the discount rate.
These terms are the engine of the deal. They reward your earliest investors for believing in you when you were just an idea. Getting them right protects your ownership and sets a fair precedent for future funding.
The valuation cap
The valuation cap is a price ceiling for your early investors. It sets the maximum valuation at which their money converts into shares. This happens no matter how high your valuation goes in the next round.
If your Series A valuation soars past the cap, note holders get a great deal. They convert their investment into equity at the cap’s price, giving them more shares for their money than new investors.
The discount rate
The discount rate is a straightforward reward. It gives your early investors a percentage discount on the share price set in your future priced round. A standard discount is 20%.
If your Series A investors buy shares for $1.00 each, your note holders with a 20% discount get them for just $0.80.
How the math works
Investors don’t choose between the cap and the discount. They get the benefit of whichever term gives them a lower share price. The note converts at the lower of the two prices.
Let’s go back to our "ConnectSphere" example:
- Note amount: $100,000
- Valuation cap: $6 million
- Discount rate: 20%
- Series A valuation: $10 million (at a $1.00 per share price)
Let’s run the numbers for the investor.
Price based on the discount:
- The Series A share price is $1.00.
- The 20% discount gives the note holder a price of $0.80 per share.
Price based on the valuation cap:
- The price is the cap divided by the number of pre-money shares.
- This gives a price of $0.60 per share ($6M cap / $10M shares).
Here, the valuation cap gives the investor a better deal ($0.60 is better than $0.80). So, their $100,000 converts at $0.60 per share, giving them a larger ownership stake.
Example
An investor’s note has a $5M cap and a 20% discount. The company later raises a Series A at a $10M valuation. The cap provides a lower share price than the discount. The investor’s note converts at the $5M valuation, rewarding their early risk.
Comparing funding options: Notes vs. safes vs. priced rounds
Choosing how to raise your first capital is a huge decision. You are setting the foundation for your startup’s financial future.
The three common paths are convertible notes, safes, and priced rounds. Each comes with trade-offs. Knowing the difference helps you pick the right tool for the job.
The core differences
Convertible notes and safes are built for one thing: speed. They let you lock in funding without a formal valuation.
A priced round forces the valuation conversation now. You and your investors agree on your company’s worth today. This makes it a more complex and expensive process.
So, what’s the difference between a note and a safe? A convertible note is legally debt. It has an interest rate and a maturity date.
A safe, pioneered by Y Combinator, is not debt. It has no interest and no expiration date. This makes it a bit more founder-friendly in some cases.
Before asking how can I find investors, decide which instrument fits your needs.
Convertible note vs. safe vs. priced round
This table breaks down the three options side-by-side.
| Feature | Convertible Note | SAFE | Priced Round |
|---|---|---|---|
| Legal Status | Debt instrument | Not debt (a warrant) | Direct equity sale |
| Valuation | Deferred until a future round | Deferred until a future round | Set immediately |
| Complexity | Low | Very Low | High |
| Legal Costs | ~$5k – $15k | ~$2k – $5k | ~$25k – $50k+ |
| Maturity Date | Yes (typically 18-24 months) | No (does not expire) | Not applicable |
| Interest Rate | Yes (typically 2-8%) | No interest accrues | Not applicable |
Which one should you choose?
Your choice boils down to your specific situation.
- Choose a note or safe if speed is everything. They’re perfect for pre-seed or seed rounds when momentum is critical.
- Choose a priced round when you have serious traction and can negotiate a strong valuation. This is standard for Series A and beyond.
Global convertible-bond issuance reached $80.1 billion in the first half of 2025, a 17.6% increase year over year, according to White & Case’s market commentary.
Example
A new SaaS startup with an MVP and a few users would use a safe or a convertible note to raise its first $500k. An established company with $1M in ARR raising a Series A will use a priced round.
The pros and cons for founders
A convertible note is a powerful tool, but it’s not always the right fit. It comes with a distinct set of trade-offs. Understanding both sides helps you negotiate terms that protect your company.
The advantages
The biggest pro is simple: you get cash without the pain of a priced round. That speed lets you keep your momentum.
- Speed and simplicity: Close a note round in weeks, not months. Negotiations focus on just a few key terms.
- Lower legal costs: A simpler agreement means fewer billable hours. Founders can save $10,000 to $30,000.
- Delayed valuation: You avoid valuing your company when it’s riskiest. This lets you gain traction to command a higher valuation later.
The disadvantages
While speed is appealing, convertible notes introduce risks. The biggest headaches come from the fact that a note is debt.
- It’s still debt: A convertible note sits on your balance sheet as a liability. This can make it harder to get other loans.
- Cap table complexity: Raising multiple notes with different caps creates a mess. The conversion math gets complicated and can lead to disputes.
- Maturity date risk: Every note has an expiration date. If you fail to raise a priced round before it matures, investors could demand their money back.
Convertible notes are a go-to for funding in uncertain economies. In a recent year, global convertible issuance hit roughly $90 billion in a single year. You can learn more about this market trend from EY.
Example
A startup raises three notes over 18 months, each with a different cap: $4M, $6M, and $8M. When they raise a Series A, figuring out how each note converts becomes a complex job for lawyers. This can create friction with new investors.
Frequently asked questions
Here are a few of the most common questions about how convertible notes work.
What is a standard valuation cap for a seed-stage startup?
There’s no magic number, but there is a typical range. For most US seed-stage companies, valuation caps land between $5 million and $15 million.
The final number depends on:
- Market: Hot spaces like AI command higher caps.
- Team: Founders with successful exits have more leverage.
- Traction: More revenue or users means a stronger argument for a higher cap.
- Geography: Silicon Valley startups usually get higher caps than those in emerging tech hubs.
Does a convertible note show up as debt on my balance sheet?
Yes. A convertible note is legally a loan. It is recorded as a liability on your company’s balance sheet.
The note stays there as debt until it converts to equity or you repay it at maturity. This is a key reason some founders prefer safes, which are not debt instruments.
What happens if my company is acquired before the note converts?
Your note agreement covers this. A "change of control" provision protects your earliest investors if an acquisition happens before a priced round.
This clause typically gives investors two choices:
- Repayment with a premium: Get their investment back, plus a bonus (often 1.5x or 2x).
- Convert to equity: Convert their note into shares at the cap right before the sale closes.
Can I have multiple convertible notes with different terms?
You can, but you probably shouldn’t. It creates a headache later.
Juggling notes with different caps, discounts, or maturity dates makes a messy cap table. The math becomes a nightmare for your lawyers and can spook new investors.
Aim for simplicity. A clean structure makes future fundraising smoother.
