If you are about to take the first check of your next raise, the instrument you sign shapes how much of the company you have committed before you ever sit down to negotiate a valuation. That decision usually gets made in a hurry, off a template someone forwarded you, and it stays on your cap table for years.
The short version. A SAFE is a contract that resolves later, into stock in an equity financing, or into cash or other proceeds in a liquidity or dissolution event; it has no maturity date and no interest. A convertible note does something similar, but it is a loan, so it carries a maturity date, usually accrues interest, and can come due. A priced round sells stock now at an agreed price per share, so no conversion math waits for you later, but it takes more corporate work to close. Founders reach for the SAFE when speed matters and they can live with pricing later. The note shows up when an investor wants a repayment right and a deadline attached to it. The priced round makes sense when the check is big enough that everyone wants ownership settled today.
Scope and assumptions
This is about raising money into your own operating company by selling your own securities. It is not about forming a pooled vehicle that invests in other companies.
One caution runs through everything below. These are contracts, and the answers move with the paper. What a SAFE does at conversion depends on which SAFE it is. What happens to a note at maturity depends on that note. Whether a priced round needs a stockholder vote depends on your certificate of incorporation. Where the outcome turns on your own documents, this article says so instead of handing you a rule that will not hold. The corporate-process discussion uses Delaware law; other states differ.
What is the difference between a SAFE, a convertible note, and a priced round?
"SAFE" is not a generic category. It stands for Simple Agreement for Future Equity, a specific instrument that Y Combinator published and maintains, released in 2013 and revised into its current post-money form in 2018. When an investor sends you "a standard SAFE," the useful question is whether it is the published post-money form, the legacy pre-money form, or something that borrows the name. Those behave differently at conversion, and the difference is measured in percentage points of your company.
A convertible note is debt. The SEC's investor-education material describes it as a loan an investor makes to the company that converts into preferred stock when the next funding round closes or other agreed conditions are met, and describes a SAFE as an agreement where the company promises a future equity stake if certain triggering events occur.
A priced round has no deferral in it. The parties agree on a pre-money valuation, and the company sells a new class or series of stock, almost always preferred, at a fixed price per share. Before it can sell that stock, it has to create it under state corporate law, and that is where most of the added cost lives.
| Question | SAFE | Convertible note | Priced round |
|---|---|---|---|
| What is it, legally? | A contract right to receive stock, cash, or other proceeds upon events specified in its terms. Not debt. | Debt. A loan that may convert into equity under its terms. | A sale of stock, right now. |
| When is the price agreed? | Later, bounded by a valuation cap or discount | Later, bounded by a valuation cap or discount | Now, as a fixed price per share |
| Maturity date? | No | Yes, commonly 12 to 36 months | Not applicable |
| Interest? | No | Usually; whether accrued interest converts or is paid depends on the note | No |
| What event resolves it? | An equity financing converts it into stock; a liquidity or dissolution event may entitle the holder to cash or other proceeds under the SAFE's terms | An equity financing may trigger conversion; maturity may lead to repayment, conversion, extension, amendment, or another outcome governed by the note's terms | Nothing converts. Shares issue at closing. |
| Filing obligations? | Set by the offering and exemption, not the instrument | Set by the offering and exemption, not the instrument | Set by the offering and exemption, not the instrument |
| If the next financing does not arrive? | It may never convert, and it stays outstanding until an event its terms address resolves it | Maturity arrives, and the note's own terms govern what happens next | The investor already owns stock |
How should founders choose between a SAFE, a convertible note, and a priced round?
Four questions a leadership team can answer internally, from its own documents, before anyone signs anything.
- What have you already committed at today's caps? For YC-style post-money valuation-cap SAFEs, each holder's estimated percentage is the investment divided by the post-money valuation cap, subject to that instrument's conversion terms. If nobody can produce the total in an afternoon, that is the finding.
- Does any instrument on your cap table have an end date, and what does that instrument say happens on it? Put every maturity date on one page against your financing timeline, then read what each note provides for that date. You are pricing before you have pricing power, and a maturity date hands part of the timing to someone else.
- Does your charter already let the board create a new preferred series? Read the certificate of incorporation for blank-check authority and check the authorized-but-unissued share count. That tells you whether a priced round looks more like a board action or a stockholder solicitation.
- Can one person explain every cap, discount, and side letter you have signed? Most-favored-nation and pro-rata terms often sit outside the main document and change the conversion outcome. If they live in someone's inbox, they are not in your model.
How conversion and dilution actually work
Y Combinator's primer for the post-money valuation-cap form states the design goal directly: the investor's percentage at conversion is the investment amount divided by the post-money valuation cap.
Assuming the valuation cap controls and no other provision produces a lower conversion price, a $500,000 investment at an $8 million post-money cap represents an estimated 6.25 percent before dilution from the priced round and any associated option-pool increase.
A discount works differently. It applies to the price per share in the priced round, commonly at 20 percent, which the document usually writes as a Discount Rate of 80 percent, meaning the holder pays 80 percent of what the new investors pay. When an instrument carries both a cap and a discount, read the conversion provision in front of you and confirm which term sets the price, and under what conditions.
Interest on a convertible note adds to the same problem. A $500,000 note at 5 percent simple interest converting 18 months in accrues $37,500. If the note converts principal plus accrued interest, the $537,500 converts rather than being repaid in cash, so the liability schedule and the dilution model have to agree.
Illustrative example: stacking instruments before a round
Illustrative assumptions: the valuation caps control; all instruments are YC-style post-money cap SAFEs; no discount, most-favored-nation amendment, or other provision changes the conversion price; and any option-pool increase is excluded until introduced separately.
Suppose you raise $1,000,000 on YC-style post-money valuation-cap SAFEs in two pieces. Six hundred thousand comes in early at a $6,000,000 post-money cap, an estimated 10 percent. Four hundred thousand comes in later at a $10,000,000 post-money cap, an estimated 4 percent. Together those holders hold an estimated 14 percent at conversion, and everyone who held stock before them absorbs that dilution.
Compare the two on dilution per dollar: $60,000 per point for the early money, $100,000 per point for the later money. Under these assumptions the earlier, smaller check caused more dilution per dollar raised. That is not a claim the bargain was unfair; a lower cap can reflect the greater risk of writing a check when there was less to look at. It does mean the early terms do more work on your cap table than their size suggests.
Then price a round on top. A $4,000,000 raise at a $16,000,000 pre-money valuation gives the new investors 20 percent at closing. The 86 percent held outside the SAFE stack is multiplied by 80 percent, landing at 68.8 percent. Add a pool increase carved out of the pre-money, which many term sheets ask for, and it lands lower still.
Two complications make real cap tables messier. First, pre-money and post-money SAFEs behave differently when they stack. A YC-style post-money valuation-cap SAFE is designed so its cap-based estimated ownership can be calculated separately from other SAFEs, although the final conversion outcome remains subject to the SAFE's conversion-price provisions. The legacy pre-money form lets the instruments dilute each other, so no holder's percentage is knowable from that holder's document alone, and a stack mixing both forms cannot be modeled from any single instrument.
Second, whether the lowest cap converts most favorably depends on how cap and discount interact under each conversion provision, on which form the instrument is, and on side terms such as most-favored-nation and pro-rata rights. All else equal, the lowest cap generally converts most favorably. All else is frequently not equal.
What happens if the next financing is delayed?
The SEC has published a caution worth reading from the company's side even though it was written for investors: a SAFE may never convert at all, because conversion depends on the stated triggers happening. A SAFE does not create a maturity-date crisis, but it remains an outstanding contractual claim until an equity financing, liquidity event, dissolution, or another event addressed by its terms resolves it.
A note is different, and this is where categorical advice fails. Maturity arrives on a date, but what happens then is set by the note in front of you. Some notes provide for repayment at maturity. Some permit or require conversion at a stated price or formula. Some give the holder an election among those. Some leave the parties to negotiate an amendment or extension, which takes the holder's signature.
What holds across the variations is the direction of leverage. As maturity approaches, the terms available to you are increasingly terms the holder has to agree to, and changing the maturity date, the interest rate, or the conversion terms generally takes that holder's consent. Not a negotiation you want in the month you are closing a round. A note that reaches maturity without the repayment, conversion, extension, or other action its terms require can also read poorly in diligence, less for the dollars than for what it says about who was watching the calendar.
A convertible note also sits on the balance sheet as a liability with accrued interest until it converts or is repaid, while a SAFE has no maturity date or maturity-based repayment obligation. That is not the same as saying the holder can never receive cash. Under the published post-money form, a liquidity event entitles the holder to the greater of a return of the purchase amount or as-converted proceeds, and a dissolution event entitles the holder to the purchase amount back, in each case junior to creditors and outstanding indebtedness and on par with non-participating preferred stock, so what is actually paid depends on the priority terms and the assets available. Two related cautions belong to finance rather than to the term sheet: a conventional convertible note is drafted as debt, but its tax and accounting consequences have to be evaluated under its actual terms, and a SAFE's own statement that it is not a debt instrument does not by itself resolve every tax or financial-statement classification question.
Why does a priced round take more corporate process?
A priced round asks the company to create a security that does not exist yet.
Under Section 151(a) of the Delaware General Corporation Law, the terms of a series of preferred stock may be fixed in a board resolution adopted under authority expressly vested in the board by the certificate of incorporation. Delaware law can therefore permit a board to establish a preferred series without a stockholder-approved charter amendment, if sufficient blank-check authority and share capacity already exist. In many first institutional priced rounds, however, the financing still involves an amended and restated charter containing the negotiated preferred-stock rights. The NVCA (National Venture Capital Association) model legal documents, the reference set many venture financings start from, are built around a certificate of incorporation carrying those negotiated rights.
If a charter amendment is required, Section 242 generally requires board approval and the stockholder votes required by the statute and the existing charter, including any applicable class vote. The useful question early is which path your round takes, and that is knowable today from your charter, your authorized-share count, and the document set your investor expects to use.
The second process item is your common-stock valuation. Treasury Regulation Section 1.409A-1(b)(5)(iv) defines the fair market value of stock that is not readily tradable as a value determined by the reasonable application of a reasonable valuation method. It treats a valuation as unreasonable if it fails to reflect information available after the date of the calculation that may materially affect value, or if it was calculated more than 12 months earlier. An independent appraisal meeting the stated requirements carries a rebuttable presumption of reasonableness.
The regulation does not say that a financing triggers a new appraisal or that option grants have to stop. What it does is make new material information relevant. A priced round may provide material new information that must be considered, although the negotiated preferred-stock price is not itself necessarily the fair market value of common stock. So a priced round will commonly require the company to revisit its existing common-stock valuation before making additional option grants. Put that in the round timeline, since it can affect when you can grant options to the person you are recruiting the same quarter.
Does the instrument change your securities filings?
All three are securities. What sets your filing obligations is not which instrument you signed but how the offering was structured and which exemption you relied on.
Section 4(a)(2) of the Securities Act of 1933 exempts transactions by an issuer not involving any public offering. Rule 506 under Regulation D is a nonexclusive safe harbor under Section 4(a)(2). If the company sells any of these instruments in an offering relying on Rule 506, it must file Form D, a notice of the exempt offering submitted to the SEC. States retain authority to require notice filings and fees for Rule 506 offerings, with the applicable triggers, deadlines, and requirements determined under each state's rules. Other exemptions may carry different federal and state notice requirements.
Keep four things separate: the instrument you sold, the exemption you relied on, the federal Form D, and the state notice filings. A SAFE round that felt informal is not a lighter regulatory event than a priced round of the same size under the same exemption.

Practical takeaways
- Estimate your fully diluted position at today's caps before the next check lands. For YC-style post-money valuation-cap SAFEs the arithmetic is investment divided by the valuation cap, subject to each instrument's conversion terms.
- Read the maturity and amendment provisions of every note you have issued. That note, not a general rule, decides whether an approaching date is administrative or a negotiation.
- Check your charter for blank-check preferred authority and share headroom before agreeing to a priced-round timeline. That reading, plus the document set your investor expects, tells you what the process involves.
- Treat Form D and state notice filings as a function of the offering, not the instrument. The obligation follows the exemption relied on. If either a SAFE round or a priced round relies on Rule 506, the federal Form D framework applies, while applicable state notices and fees depend on each state's requirements.
Frequently asked questions
Is a SAFE better than a convertible note for an early raise?
They are different trades. A SAFE has no maturity date or maturity-based repayment obligation and no interest, so it does not come due on a maturity date, though its terms may entitle the holder to cash or other proceeds in a liquidity or dissolution event. A note gives the investor a claim that matures on a date, usually with interest, and the note's terms govern what that date brings. Investors who want downside protection tend to ask for a note. The cap will usually matter more to your dilution than which of the two you pick.
Do I have to file anything with the SEC if I only raise on SAFEs?
SAFEs are securities, and the filing question turns on the offering rather than the paper. If the SAFE round relies on Rule 506, the Form D framework applies as it would for notes or preferred stock. States retain authority to require notice filings and fees for Rule 506 offerings, with the triggers, deadlines, and requirements set by each state's rules. A different exemption can carry different requirements.
Does a priced round always require a charter amendment?
No. Delaware law can permit the board to establish a preferred series without another stockholder-approved charter amendment, where the existing certificate of incorporation provides sufficient blank-check authority and enough authorized but unissued shares. Many first institutional priced rounds nevertheless use an amended and restated charter to establish the negotiated preferred-stock rights, which is the structure the NVCA model document set is built around. The answer for your round therefore depends on your existing charter and the financing terms your investor expects.
Closing perspective
Founders spend their negotiating energy on the cap and almost none on the instrument, when the instrument governs the case where the plan slips. A SAFE puts no date on the calendar. A note does, and what that date brings is written in the note. A priced round settles ownership now and pays for it in process.
Each instrument commits the company to a future economic outcome on terms established before the company knows what that outcome will cost. That is a reasonable trade once. It gets harder to defend the fourth time, at the fourth cap, in a form you did not read.
So much of your dilution is decided the day you sign rather than the day the instrument converts, and the arithmetic gets done either way. It just gets done by the next investor's lawyer, while their term sheet sits on your desk. Do it first. Open the cap table, model what every outstanding instrument would do under the financing and downside scenarios its own terms address, and write the numbers down where your co-founders can see them.
