Key takeaways
  • Both SAFEs and convertible notes are a bet on the future.
  • A SAFE was originally developed by Y Combinator in the United States.
  • A convertible note is a loan — it has a principal amount, an interest rate, and a maturity date.

Early-stage founders often do not want to set a company valuation at the seed stage — too early means leaving money on the table; too high means creating expectations you cannot meet. SAFEs (Simple Agreements for Future Equity) and convertible notes solve this by letting you take money now and convert it into shares later, at a price determined by a future financing round.

These instruments have become the dominant tool for Ontario startup seed financing. They are faster to close than a priced equity round, cheaper to document, and familiar to most angel investors and early-stage funds. But they are not without complexity — and they are not identical to each other.

The Core Idea: Defer the Valuation

Both SAFEs and convertible notes are a bet on the future. The investor gives you money today. Instead of receiving shares immediately, they receive a right to convert their investment into shares at a later date, typically:

The conversion usually happens at a discount to the price paid by future investors (rewarding early investors for taking more risk) or at a price calculated by reference to a valuation cap (protecting them from excessive dilution if your valuation explodes).

SAFEs: Simple Agreements for Future Equity

A SAFE was originally developed by Y Combinator in the United States. It has become widely used in Canada, including Ontario, though the documents often need adaptation for Canadian legal and tax purposes.

How a SAFE works

  1. The investor pays a sum of money to the company.
  2. The company does not issue shares and is not obligated to repay the money on a schedule.
  3. When a triggering event occurs (usually a priced round above a set threshold), the investment converts into shares at either:
  1. If the company is sold before conversion, the SAFE may convert or pay out depending on the agreement terms.

What a SAFE is not

A SAFE is not debt. The company does not owe the investor a repayment obligation. If the company fails and never raises a priced round, the investor typically loses their money. This is important for accounting purposes and for understanding the investor's risk.

Convertible Notes: The Debt Variant

A convertible note is a loan — it has a principal amount, an interest rate, and a maturity date. Like a SAFE, it converts into equity on a triggering event. Unlike a SAFE, if conversion never happens, the company still owes the money (plus interest) and must repay it at maturity.

Key terms in a convertible note

What happens at maturity if no conversion?

This is the most important question founders overlook. If the note matures and you have not raised a qualifying round, you owe the money back — with interest. Some notes include automatic conversion at maturity into shares at the cap price; others give the investor a choice. Read the maturity provisions carefully before signing.

Ontario-Specific Considerations

Securities law compliance

SAFEs and convertible notes are securities in Ontario. Issuing them requires a prospectus or an exemption under the Securities Act (Ontario) — typically the accredited investor or private issuer exemption (as of writing — verify with the OSC). A report of exempt distribution may be required after closing.

Tax treatment for the company

A SAFE is not debt, so no interest deduction is available. A convertible note generates deductible interest if it is a genuine debt obligation and the funds are used to earn income. Confirm the tax treatment with your accountant, particularly for any premium paid on conversion.

Tax treatment for the investor

Investors in SAFEs and notes should obtain their own tax advice on the adjusted cost base of shares received on conversion and on any interest income or capital gains implications. This varies by the investor's specific tax position.

Drafting Pitfalls to Avoid

Frequently asked questions

Is a SAFE better than a convertible note for my company?

SAFEs are simpler and create no repayment obligation, which is generally better for founders. Convertible notes are sometimes preferred by investors who want the creditor protection or who are uncomfortable with the SAFE structure. The right answer depends on what your investor will accept and your company's stage.

Can multiple SAFEs or convertible notes from different investors have different terms?

Yes, but this creates a complex conversion calculation at the next round. A cap table model should project the post-conversion ownership before you close each new instrument.

Do convertible notes dilute founders immediately?

No — they dilute at conversion. But they are dilutive instruments, and founders should model the fully diluted cap table (including all outstanding SAFEs, notes, and option pools) before accepting any new investment.

Can I use a convertible note with a family member as the investor?

Possibly, under the private issuer exemption. But document everything carefully — a poorly structured family note is a tax risk if the CRA scrutinizes it as a shareholder loan or dividend substitute.
