Convertible Notes vs. SAFEs: What Founders Should Know

The short answer: A convertible note is a loan that converts into equity at a later round, while a SAFE is a simple agreement for future equity that is not debt. Both let you raise money quickly without setting a valuation today. The right choice depends on your investors, your timeline and how much complexity you want to manage.

How a convertible note works

A note is a short-term loan. The investor lends money, interest accrues, and at a priced round the balance converts into shares, usually at a discount to the new investors' price or subject to a valuation cap. Because it is debt, a note has a maturity date. If you have not raised a priced round by then, the investor can technically ask for repayment or negotiate an extension. That is rarely what anyone wants, but founders should understand it before signing.

How a SAFE works

A SAFE (simple agreement for future equity) is not a loan. It has no interest and no maturity date. The investor pays now and receives shares when a triggering event occurs, typically a priced financing. Like a note, it often includes a valuation cap, a discount, or both. SAFEs were designed to be short and standardized, which is why many early-stage deals use them.

Key differences

• Debt or equity: notes are debt on your balance sheet; SAFEs generally are not.
• Interest: notes accrue interest that converts into extra shares; SAFEs do not.
• Maturity: notes come due; SAFEs stay open until a trigger.
• Complexity: SAFEs are usually shorter and cheaper to document.
• Investor comfort: some investors prefer the creditor protections of a note.

What founders should watch

The biggest issue is dilution. Because neither instrument sets a price today, you may not see how much of the company you have sold until the next round. Stack several notes or SAFEs with different caps and the cap table can surprise you. Model the conversion under a few realistic scenarios before you accept money, and keep a running record of every instrument outstanding.

Also check how the valuation cap interacts with any discount, whether the cap is applied before or after the new money, and what happens if the company is sold before a priced round. These details matter more than the headline label.

Which is better?

Neither is better in every case. Many founders pick a SAFE for speed and low cost when raising a small amount from several angels. A note can make sense when investors want a defined repayment right or when local practice favours it. Canadian companies should also consider securities rules and how the instrument will be treated in a later financing, so speak to a qualified lawyer and accountant before you sign.

• Use whichever instrument your lead investor knows well; familiarity speeds closing.
• Avoid mixing many different terms across small cheques if you can.
• Plan to move to a priced round once you have real traction.
