Founders pick paper the way they pick fonts. The useful split is mechanical: do you need a maturity clock, a current price, or a conversion-only contract? YC’s SAFE is conversion-only. A note is debt that hopes to convert. Priced equity is ownership today. NVCA’s seed volume does not make any of those valid outside the US.

Three jobs, three papers

A note says: we will convert or we will have a debt conversation on this date. Priced equity says: you own this many shares at this price today. A SAFE says: you will own a slice when a priced round happens. If you need repayment, do not use a SAFE.

The labels do not decide priority, security, conversion price, or voting rights; the signed terms do. Compare the actual cap, discount, interest, maturity, share class, and remedies on one page instead of comparing document names.

Worked choice for a 14-month plan

If you expect a priced round in 14 months and the investor wants a reminder, a note with an 18-month maturity is the honest clock. If nobody believes a priced round will happen, sell equity or do not take the money.

In a second case, founders and investor already agree on valuation and governance, and no later round is required to set the price. Priced equity resolves ownership now; inserting a note merely creates interest and a maturity negotiation around a price the parties already know.

Interest is a price, not a decoration

Note interest accrues into the conversion. A cheap-looking 6% on an 18-month note is part of the slice. Model it on the cap table before you celebrate the discount.

On a simple-interest example, $100,000 at 6% for 18 months adds $9,000 before conversion, subject to the instrument’s actual terms. The arithmetic is illustrative, but the boundary is firm: model principal plus accrued interest, not principal alone.

Jurisdiction rewrite

US notes and SAFEs assume US securities law. Iranian and UAE vehicles need local instruments. NVCA model legal documents describe US note and priced-equity forms; the NVCA 2026 Yearbook only dates US seed. Carta private-markets is dating context. This page is not legal advice.

Counsel must map debt enforceability, corporate approvals, issuance mechanics, currency and payment rules, and conversion into a valid local share class. Changing only the governing-law line leaves the core machinery untested.

When equity is kinder

If the relationship is long and the price is agreed, priced equity ends the argument now. A stack of notes and SAFEs is how later rounds stall.

Equity is not automatically simpler: it requires present governance, approvals, and dilution to be understood. It is kinder when that work can be completed honestly now; it is not a shortcut when the parties still disagree on price or control.

Frequently asked questions

Is a SAFE safer than a note?

It is simpler, not safer. It has no clock. That can help or trap both sides.

Who wants a note?

An investor who needs a dated conversation if the round never happens.

Can I mix all three?

You can. Cleanup cost grows with every mix. Prefer one paper per raise.

Does NVCA seed volume pick the paper?

No. It only shows that US seed is busy. Your jurisdiction still owns the form.

Answers to the questions this topic usually leaves hanging.
