On Carta, SAFEs made up 93% of pre-seed rounds by count in the second quarter of 2026. If you are raising your first outside cheque, it will very likely arrive on one. A SAFE (simple agreement for future equity) is a contract: the investor pays now and gets shares later, normally when the startup raises a priced equity round. It is not a loan. There is no interest and no maturity date, and the price the investor eventually pays is set by a valuation cap, a discount, or both. Indian companies are the exception. They cannot issue the US-form SAFE as written, so they use CCPS-based structures such as 100X.VC’s iSAFE, or a FEMA-compliant convertible note.
Key takeaways
- Y Combinator launched the SAFE in 2013 and moved to a post-money version in September 2018. On that form, investment ÷ cap gives the investor’s stake before the priced round.
- The cap is the most an investor can pay per share; the discount is a percentage off the next round’s price. A SAFE carrying both converts at whichever price is lower. The investor never gets both.
- In our example, a $1M SAFE with a $10M cap and a 20% discount ends up owning 8.0% after a strong Series A and 11.4% after a weak one.
- Post-money SAFEs don’t dilute each other, so nearly all of the dilution lands on the founders. Three SAFEs at rising caps can still add up to 18.75% of the company.
- The US-form SAFE doesn’t fit India’s Companies Act or FEMA rules. Founders there use the CCPS-based iSAFE, or convertible notes issued by DPIIT-recognised startups at a minimum of ₹25 lakh per tranche.
What is a SAFE note?
The SAFE was drafted in 2013 by Carolynn Levy, a partner at Y Combinator, as a simpler alternative to convertible debt, according to YC’s documents page. YC gives the forms away and describes the valuation cap as typically “the only term to negotiate.” People call it a “SAFE note”, but the name is a little misleading: nobody lends anybody anything, so it isn’t really a note.
Until something triggers conversion, the investor owns no shares and has no vote. For most SAFEs that trigger is the next priced round. If the company is acquired or lists first, the holder takes the greater of its money back or the as-converted value. If the company shuts down, SAFE holders queue behind creditors to recover what they paid, the YC SAFE User Guide says. The US SEC has cautioned investors that if no trigger ever happens, a SAFE may simply never convert.
Why the post-money version took over
YC brought out the post-money SAFE in late September 2018. On the original pre-money form, the cap was measured before other SAFEs were counted, which made it hard for any investor to say what stake they had actually bought. The post-money form measures the cap after all the SAFE money but before the priced round, so the maths is simple: $500,000 at a $5M post-money cap buys 10%, per the YC User Guide. The price of that clarity is paid by founders, because every additional SAFE dollar dilutes them and leaves earlier SAFE holders untouched. Investors and founders have settled on it anyway. In Q2 2026, 91% of SAFEs on Carta were post-money, and SAFEs accounted for 93% of pre-seed rounds by count (data as of August 2026).
Valuation cap vs discount vs MFN: what’s the difference?
YC’s current US forms come in three flavours: a cap with no discount, a discount with no cap, and an uncapped MFN version. Any of the three can carry an optional pro rata side letter.
| Term | What it does | Who it favours |
|---|---|---|
| Valuation cap | Sets the maximum valuation the SAFE converts at. Conversion price = cap ÷ company capitalization. | Investor, if the priced round comes in well above the cap |
| Discount | Converts at a percentage below the price new investors pay. WilmerHale puts the typical range at 10–30%. | Investor, if the round is priced close to or below the cap |
| Cap + discount | The investor gets whichever price is lower, never both. YC no longer publishes this form, but 21% of capped post-money SAFEs on Carta still carried a discount in H1 2026. | Investor |
| MFN (most favoured nation) | No cap and no discount. If the company later issues SAFEs on better terms, the holder can switch to them. Per the YC guide, this is usually a one-time choice. | Founder, in the short term |
| Pro rata side letter | Lets the holder buy into the priced round to keep its stake. Works only with post-money cap forms. | Investor |
One trap in the paperwork: YC’s documents define “Discount Rate” as 100% minus the discount, so a 20% discount shows up as an 80% rate. WilmerHale says this trips people up often.
How a SAFE converts, worked through
Take a hypothetical startup. The founders own 9,000,000 shares and the option pool another 1,000,000, so there are 10,000,000 in all. An investor writes a $1M SAFE (about ₹9.5 crore) with a $10M post-money cap and a 20% discount. We picked cap plus discount so both mechanics come into play, and assumed no option-pool top-up at the Series A to keep the numbers clean. Rupee figures use ₹94.92 to the dollar, the closing rate on 16 October 2026. We checked the arithmetic in Python.
Step 1, the cap price. $1M ÷ $10M means the SAFE owns 10% of the company going into the Series A. Company capitalization = 10,000,000 ÷ (1 − 0.10) = 11,111,111 shares. Cap price = $10M ÷ 11,111,111 = $0.90 per share.
Step 2, the discount price. That is 80% of whatever the Series A price turns out to be. The SAFE converts at the lower of the two.
Scenario A: Series A at $20M pre-money, so the cap applies
New investors put in $5M at a $20M pre-money valuation. Counting the SAFE at its cap conversion, there are 11,111,111 pre-money shares, which puts the Series A price at $20M ÷ 11,111,111 = $1.80. A 20% discount would give 0.8 × $1.80 = $1.44. The cap price of $0.90 is cheaper, so it wins. The SAFE investor receives 1,111,111 shares, worth $2M at the Series A price, double the original cheque.
Scenario B: Series A at $8M pre-money, so the discount applies
This time the round is weaker: $3M at an $8M pre-money valuation, and the discount price undercuts the cap. Solving price × 10,000,000 + $1M ÷ 0.8 = $8M gives a Series A price of $0.675, so the SAFE converts at 0.8 × $0.675 = $0.54. That buys 1,851,852 shares, worth $1.25M at the Series A price. A 20% discount always works out to that 25% uplift.
| Line item | Scenario A ($20M pre) | Scenario B ($8M pre) |
|---|---|---|
| Series A price per share | $1.80 | $0.675 |
| Cap price / discount price | $0.90 / $1.44 | $0.90 / $0.54 |
| Mechanism used | Cap | Discount |
| SAFE shares issued | 1,111,111 | 1,851,852 |
| New Series A shares | 2,777,778 | 4,444,444 |
| Total shares after round | 13,888,889 | 16,296,296 |
| Post-money valuation | $25M (≈ ₹237 crore) | $11M (≈ ₹104 crore) |
| Founders (9,000,000 shares) | 64.80% | 55.23% |
| Option pool (1,000,000) | 7.20% | 6.14% |
| SAFE investor | 8.00% | 11.36% |
| Series A investors | 20.00% | 27.27% |
On these terms the two prices meet at a $12.5M pre-money valuation; above it the cap kicks in, below it the discount does. Notice where the founders end up. In Scenario A their 90% drops to 81% once the SAFE converts, then to 64.8% after the Series A money lands. And a real Series A usually tops up the option pool as well. The YC guide leaves that increase out of the SAFE’s capitalization, which means the founders, and not the SAFE holder, absorb it.
SAFE or convertible note?
| Feature | SAFE | Convertible note |
|---|---|---|
| Legal nature | A contract for future equity, not a loan | Debt, so the company is legally obliged to repay (SEC) |
| Interest | None | Accrues interest, which usually converts into extra shares |
| Maturity date | None | Yes, so the investor can demand repayment or renegotiate |
| Pricing terms | Cap, discount, or MFN | Cap and/or discount |
| Paperwork | Short standard forms from YC | Longer, with more terms to negotiate |
| Insolvency ranking | Behind creditors (YC guide) | Ranks as a creditor |
| India use | Not as a US form; use CCPS (iSAFE) instead | Allowed for DPIIT-recognised startups, at least ₹25 lakh per tranche |
For a US company, or an Indian one that has flipped to Delaware, the SAFE is usually the cheaper and quicker option. Some old-school angels still want a note. Startup lawyer José Ancer has proposed a compromise, a note with a long maturity and low interest, Holloway’s guide notes.
Can Indian startups use SAFE notes?
Not in the form YC publishes. Section 43 of the Companies Act, 2013 recognises two kinds of share capital, equity and preference. A SAFE allots nothing on day one, so it is neither, and that is why Indian lawyers wrap SAFE economics inside CCPS (compulsorily convertible preference shares). No reported court ruling has yet dealt with a pure-form SAFE, according to LawSikho’s 2026 analysis, and Khurana & Khurana tells founders to stay away from the US form entirely, given the exposure under deposit rules and FEMA. We could not find an RBI circular that recognises SAFEs, or one that even mentions them by name.
Option 1: iSAFE from 100X.VC
100X.VC brought the iSAFE note to India in 2019. The money sits in the company’s books as CCPS, so nobody is diluted until a priced round, and iSAFE holders rank ahead of equity shareholders for getting their capital back. Like YC’s version, it can carry a cap, a discount or both. Being a preference share, it has to follow the Companies Act rules on private placement and share issues (Vinod Kothari Consultants). LLPs can’t use it; only companies can.
Option 2: a FEMA-compliant convertible note
This route is open only to DPIIT-recognised startups. A non-resident has to put in at least ₹25 lakh in a single tranche, and the RBI wants the inflow reported on Form CN within 30 days. Citizens and entities of Pakistan and Bangladesh can’t invest this way. An amendment notified on 1 April 2022 stretched the conversion window from five years to ten.
The FEMA pricing catch for foreign investors
When a convertible instrument goes to a non-resident, the price or the conversion formula has to be fixed upfront, and the conversion price can’t fall below fair value at the time of issue. That is where SAFE logic runs into trouble. A cap implying a price below the fair value certified at issue would breach FEMA pricing norms. Tax is less of a headache than it used to be. Section 56(2)(viib), the so-called angel tax, does not apply to consideration received from 1 April 2025. The same analysis warns that Section 56(2)(x) can still apply if conversion allots shares well below fair value.
Founders who set up a US (Delaware) parent can use YC SAFEs at the parent level as normal. Any money sent down to the Indian subsidiary is still subject to FEMA. YC also publishes cap-only SAFEs for Canada, the Cayman Islands and Singapore, and in every case it advises getting a local lawyer.
Four ways founders get SAFEs wrong
1. Stacking SAFEs without modelling the total
Post-money SAFEs do not dilute one another. Each stake is calculated on its own and they simply add up. Raising your cap with every SAFE feels like momentum. If the cheques grow as fast as the caps, though, you are selling the same slice each time.
| SAFE | Amount | Post-money cap | Stake |
|---|---|---|---|
| 1 | $500,000 (≈ ₹4.7 crore) | $8M | 6.25% |
| 2 | $750,000 (≈ ₹7.1 crore) | $12M | 6.25% |
| 3 | $1,000,000 (≈ ₹9.5 crore) | $16M | 6.25% |
| Total | $2.25M (≈ ₹21.4 crore) | – | 18.75% |
Run that against our example cap table, where the founders start at 90%. The three SAFEs take them to 73.1% before the Series A. A Series A selling 20% then leaves them with 58.5%, and that is before any option-pool top-up.
2. Treating the cap as the company’s valuation
A cap limits one investor’s conversion price. It is not what the market says the company is worth. Caps have been climbing, too: Carta’s data shows the median cap on SAFEs above $2.5M hit $35M in Q2 2026, 40% higher than a year earlier. Agree to a cap you can’t grow into and you are setting up a flat or down Series A. A weak priced round is precisely when the discount bites and the SAFE holder’s share grows.
3. Forgetting the option pool and pro rata rights
The pool top-up at the Series A comes out of the founders’ share. Pro rata side letters let SAFE holders claim part of the new round, which can crowd the lead investor’s allocation. Be choosy about who gets pro rata; the YC guide suggests tying it to a minimum cheque size.
4. Copying a US template into an Indian company
An instrument Indian law doesn’t recognise can cause trouble on deposit rules, FEMA filings and pricing. Late FC-GPR filings alone can attract penalties of up to three times the amount involved, Treelife notes. Stick to a CCPS or iSAFE structure or a compliant convertible note, and get the conversion formula checked against a valuation report.

FAQ
Is a SAFE debt or equity?
Neither, to begin with. It is a contract for future equity with no interest and no repayment date, and it turns into shares only when a trigger event, usually a priced round, happens.
What happens to a SAFE if the startup never raises a priced round?
It may never convert. If the company is acquired, the holder gets the greater of its money back or the as-converted value. If the company dissolves, the holder stands behind creditors for its purchase amount and may get back little or nothing.
Does a SAFE investor get both the cap and the discount?
No. Where a SAFE has both, the investor converts at whichever price is lower. The two don’t stack.
How do I calculate ownership on a post-money SAFE?
Divide the investment by the post-money cap. $1M at a $10M cap is 10% before the priced round; the new money then dilutes that stake along with everyone else’s.
Is iSAFE legal in India?
Yes. It is structured as CCPS, which the Companies Act recognises. It still has to follow private placement rules and, with foreign investors, FEMA’s pricing and reporting requirements.
What is the minimum for a convertible note in India?
₹25 lakh in a single tranche from a non-resident investor. Only a DPIIT-recognised startup can issue one, and it must convert or be repaid within ten years.
