SAFEs vs. Convertible Notes for MN Startups

What is a SAFE, and how does it actually work?

A SAFE is a contract in which your company takes an investor’s money now and promises them stock later, when a defined trigger event happens (usually your next priced financing round). It is not stock, and it is not a loan. The U.S. Securities and Exchange Commission (SEC) says so plainly in its investor bulletin on SAFEs: “SAFEs are not common stock.”

Mechanically, the investor sends money today, and in exchange your company owes them shares at a future date on terms you agree to now, most importantly a valuation cap or a discount (more on those below). A SAFE carries no interest, no maturity date, and no promise of repayment. If a conversion trigger never arrives, a plain SAFE generally waits rather than coming due. Because a SAFE is a promise of future equity in a common venture, it is generally treated as an “investment contract,” and Minnesota law lists an investment contract as a security (Minn. Stat. § 80A.41). In practice that treatment pulls essentially every SAFE into securities law, a point I return to below. In my practice, the SAFEs I see most often are the post-money version popularized by startup accelerators, which is friendlier to investors than founders sometimes realize. One thing founders overlook: a SAFE can trigger unexpected tax when it converts, so model the conversion before you sign.

How is a convertible note different from a SAFE?

A convertible note starts as a loan. Your company borrows money that accrues interest and carries a maturity date, and instead of being repaid in cash, the loan is built to convert into stock when a trigger event happens. That debt wrapper is the core difference from a SAFE: a note is money you owe until it converts, while a SAFE is only a promise of future shares. The same Minnesota statutory definition that captures a SAFE lists a “note” as a security too, so both instruments sit inside securities law.

Both defer the valuation question, and both usually carry a cap or a discount. The practical differences flow from the debt label: interest accrues and typically converts into extra shares, a maturity date creates a deadline, and if the company fails, a noteholder is a creditor ahead of everyone holding stock. Here is the contrast at a glance.

That last row explains a lot of the market: a founder who wants to close a first check in a week often reaches for a SAFE, and the tax line between debt and equity financing is one reason the choice is not purely cosmetic.

What do valuation caps, discounts, and MFN clauses do?

Three terms do most of the work in a SAFE or note: the valuation cap, the discount, and the most-favored-nation (MFN) clause. A valuation cap sets the highest company value at which the investor’s money converts, so a lower cap buys the investor more shares. A discount gives the investor a fixed percentage break off the price your priced-round investors pay. An MFN clause lets an early investor claim any better terms you later grant a different investor.

A cap and a discount both exist to reward investors for taking early risk, and when a SAFE carries both, the investor usually converts at whichever gives the lower price. The cap is the term founders underestimate: it works as a rough ceiling on valuation for that money, so a $4 million cap on a company that later raises at $12 million roughly triples that investor’s effective ownership compared with the new-money price. An MFN clause is often delivered through an investor side letter rather than the SAFE itself, and it means the terms you give a later investor can reach back to earlier ones. In my experience, founders negotiate the cap hard and skim the MFN language, then are surprised when a better later deal resets terms across the whole early group.

What does dilution actually look like when a SAFE or note converts?

Dilution is easiest to see with numbers, so here is a simplified hypothetical (illustration only, not legal or tax advice, and it sets aside real-world details like option pools and several stacked SAFEs). Say you raise $500,000 on a SAFE with a $5 million post-money valuation cap. Later you close a priced round that values the company at $10 million. Because your cap ($5 million) is below the round valuation ($10 million), the SAFE converts as if the company were worth $5 million, not $10 million.

Here is the arithmetic. At a $5 million post-money cap, a $500,000 SAFE converts into roughly 10 percent of the company ($500,000 divided by $5 million). If that same $500,000 had instead converted at the $10 million round valuation, it would buy roughly 5 percent. The cap nearly doubled the investor’s stake, and the extra points come out of the founders’ and employees’ ownership, not the new investors’ money. Now stack three or four capped SAFEs from a busy fundraising season, add the interest a convertible note piles on before it converts, and the combined bite can surprise a founder who only ever looked at each instrument one at a time. The most useful habit here is to model the fully diluted cap table before you sign, the same discipline that matters when you later face anti-dilution adjustments in a down round.

How do a note’s maturity date, interest, and insolvency risk change the picture?

Because a convertible note is debt, three features attach that a SAFE does not carry: a maturity date, accruing interest, and creditor status if the company fails. A maturity date is a genuine deadline, often a year or two after signing, and a SAFE has none. If the note matures before you have raised a priced round, you are relying on a good-faith extension or an agreed conversion, and a company that cannot pay is technically in default on a debt.

That debt character also changes what happens in a wind-down: a noteholder is a creditor, paid ahead of everyone holding stock, while a SAFE holder sits with the equity. Founders sometimes ask whether a note’s interest rate runs into Minnesota’s usury law. The general ceiling is $8 on $100 for one year, or 8 percent a year (Minn. Stat. § 334.01), but a separate statute removes any rate limit on an extension of credit to an organization, a term the statute defines to include a corporation or limited liability company (Minn. Stat. § 334.022). Because your startup is almost always a corporation or an LLC, a normal convertible note rate sits comfortably outside any Minnesota usury concern. When the note does convert, the mechanics of converting the debt into equity and getting board approval for a convertible note are worth handling with care rather than treating as automatic.

What control, information, and pro-rata rights come with each instrument?

Neither a SAFE nor an unconverted convertible note gives your investor voting rights, a board seat, or the rights of a shareholder. Those come only when the instrument converts into actual stock. Before conversion, the holder’s rights are whatever the contract grants, which for a bare SAFE or note is very little.

What sophisticated investors often add is a pro-rata right, the option to invest again in later rounds to hold their percentage, plus information rights and sometimes a board observer seat. Those are negotiated separately, and they behave differently once the money converts and the investor becomes a stockholder with charter and statutory rights. If you are issuing notes, the question of preemptive rights in a convertible round deserves attention, because a promise made casually at the SAFE stage can constrain how you run your next raise. The practical point: read the side letters as closely as the SAFE, because that is where the real control terms usually live.

Which securities-law exemptions let a Minnesota startup issue a SAFE or note?

Because a SAFE and a convertible note are both treated as securities, you cannot simply sell them: every sale needs either registration or an exemption, and almost no startup registers. The federal foundation is the private-offering exemption in Section 4(a)(2) of the Securities Act of 1933, which covers “transactions by an issuer not involving any public offering” (15 U.S.C. § 77d(a)(2)). Because that language is broad, most founders rely on its bright-line safe harbor, Rule 506 of Regulation D, which comes in two forms.

Under Rule 506(b), you may sell to an unlimited number of accredited investors and up to 35 non-accredited investors who are financially sophisticated, but you cannot advertise or generally solicit the offering. Under Rule 506(c), you may advertise, but then every purchaser must be an accredited investor whose status you take reasonable steps to verify. An accredited investor is generally someone with income over $200,000 (or $300,000 with a spouse), a net worth over $1 million excluding the value of their home, or certain professional credentials. The trap I see most is a founder assuming a small, informal raise falls outside all of this: even a friends-and-family round is selling securities and still has to fit an exemption, and the same rules apply when you are later selling shares in a private company.

What Minnesota securities filing applies to a SAFE or convertible note?

A Rule 506 offering is a “federal covered security,” which means Minnesota cannot make you register it. That does not mean Minnesota is silent. State law still makes it unlawful to offer or sell a security in Minnesota unless it is a federal covered security, exempt, or registered (Minn. Stat. § 80A.49), and for a covered security the state requires a notice filing.

Here is how the two levels fit together. Congress, through the National Securities Markets Improvement Act (NSMIA), made Rule 506 offerings “covered securities” and took state registration off the table, while preserving each state’s authority to require a notice filing and charge a fee (15 U.S.C. § 77r). Minnesota uses that authority: for a covered security sold here, the state requires a notice filing that includes a copy of your federal Form D and a consent to service of process, filed shortly after your first sale to a Minnesota investor (Minn. Stat. § 80A.50), together with the applicable state fee. In practice it runs parallel to the Form D you already file with the SEC. Minnesota also offers its own state-law exemption, MNvest (Minn. Stat. § 80A.461), an intrastate crowdfunding path for a Minnesota company raising from Minnesota residents, which is a different road from the Rule 506 raise most venture-track startups run. Knowing what triggers a state blue sky filing keeps a quiet compliance step from becoming a problem later.

What factors decide between a SAFE and a convertible note for your raise?

The decision comes down to a handful of concrete factors, not a rule that one instrument is always better. Ask whether you want debt on your balance sheet at all (a note’s maturity, interest, and default risk versus a SAFE’s open-ended wait), how quickly and cheaply you need to close, what your investors are used to seeing, and what your company’s structure allows.

A SAFE usually wins when you want speed, low legal cost, and no maturity clock, which is why it dominates the earliest checks. A convertible note tends to fit when investors want the fallback of a repayment right, the accrual of interest, or the creditor priority that debt provides, or when a maturity date gives everyone a reason to get the priced round done. One factor founders miss is entity type: both instruments assume you can hand the investor stock later, so if you are an LLC (units, not shares) or an S corporation (which can hold only one class of stock), converting is more complicated than the standard forms assume. If that is you, work through convertible debt inside an S corporation before you promise a conversion your structure cannot cleanly deliver. There is no universally correct answer, only the one that fits your round, your investors, and how much of the company you are prepared to give up.

The through-line is straightforward: a SAFE and a convertible note both let you defer valuation, but a note is debt and a SAFE is not, and the cap, discount, and conversion terms decide how much ownership you actually part with. Get the instrument and its terms right at the seed stage and you avoid a cap table that surprises you at the priced round. Because both are treated as securities, the raise also has to fit a federal exemption and clear Minnesota’s notice-filing step, which is manageable once you know it is there. This is the heart of my capital-raise and securities work.
