Pre-Sign SAFE Questions What to Ask Before Signing

SAFE for Startups Questions (What to Ask Before Signing)

last updated: Apr 14, 2026
Raising money on a Simple Agreement for Future Equity (SAFE) feels like free cash — until the Series A hits and you realize you accidentally gave away half your company. You have to ask the uncomfortable questions before signing the paperwork to protect your cap table.
Here is the short version of what you need to clarify before taking the check.

TL;DR

  • Benchmark: The standard discount rate on an early-stage SAFE sits between 20% and 25%.
  • Rule: Never sign a Most Favored Nation (MFN) clause without capping it to a specific funding window.
  • Warning: Assuming a post-money SAFE functions exactly like a pre-money SAFE will result in massive, unexpected founder dilution.

Glossary

  • Valuation cap: The absolute ceiling on the valuation at which an investor's money converts into equity. You can reference the standard definitions directly in the Y Combinator SAFE repository.
  • Discount rate: A percentage reduction applied to the price per share of the next equity financing to reward early investors for taking early risk.
  • Pro rata rights: The contractual right for an investor to buy more shares in future rounds so they don't get diluted.
  • MFN provision: A clause guaranteeing the investor gets your new, better terms if you get desperate and issue a cheaper SAFE to someone else later.

How to ask the right SAFE questions

Don't just take the money. Ask these five questions before you finalize anything.
  1. Are we using a pre-money or post-money template? You have to know which template is on the table before negotiating. You can review the core mechanics in our SAFE pre-seed guide to understand how the templates evolved.
  2. What is the exact valuation cap and discount structure? Ask if the investor expects both a cap and a discount, or just one. Recent startup data from Kruze Consulting's SAFE analysis shows median seed valuation caps fall between $8,000,000 and $12,000,000, with standard discounts around 20% to 25%.
  3. Does this SAFE include an MFN clause? Ask directly if they expect Most Favored Nation status. If they do, any cheaper deal you sign six months from now will retroactively apply to them, compounding your dilution.
  4. Are you demanding pro rata rights via a side letter? Investors often want to maintain their percentage in the next round. Granting this early on limits the pool of equity available for your future Series A lead investor.
  5. What exactly triggers the conversion? Clarify if the SAFE converts at any priced round or if there is a minimum threshold of capital that must be raised. A low threshold could trigger a conversion prematurely on terrible terms.

Question template
If you need a simple email to send to your investors, copy and paste this script:

Hi [Investor Name],

Before we finalize the paperwork, I want to confirm a few mechanical details. Are we using the standard YC post-money SAFE? Also, please confirm if you are expecting both a valuation cap and a discount rate, or just a cap. Lastly, do you require any pro rata side letters?

Thanks,
[Your Name]

Benchmarks

Always run the dilution math before accepting the deal.

Sample math:
  • The setup: You raise $500,000 to $600,000 on a SAFE with a 20% to 25% discount and an $8,000,000 to $10,000,000 valuation cap.
  • The trap: If your Series A prices the business at $15,000,000 to $20,000,000, the early investors convert at the lower cap, not the higher Series A price.
  • The result: They buy shares at a massive discount, grabbing 5% to 6% of your company instead of the 3% to 4% you assumed. For a deeper dive into the exact mechanics of these conversion outcomes, read Carta's breakdown on SAFE conversions. Instead of guessing, plug your numbers into our SAFE Series A calculator first.

Pre-money vs Post-money SAFE

You have to understand the fundamental difference between the two standard structures.
  • Pre-money SAFE: When the SAFE converts during a priced round, the dilution is shared by both the founders and the existing investors. This is generally much friendlier to founders.
  • Post-money SAFE: The investor's ownership percentage is locked in at the time of signing. When the priced round happens, the founders absorb nearly 100% of the dilution from all previously issued SAFEs.

Risks

SAFE notes are designed to be fast, but speed introduces dangerous blind spots.
  • Stacking SAFEs: Issuing multiple post-money SAFEs at different valuation caps causes extreme dilution. Since the investor's ownership is locked in for each note, you bear the cumulative dilution during the equity round.
  • Premature conversion: If the conversion threshold is set too low, a small bridge round could force the SAFEs to convert early, locking you into permanent cap table damage.

Will negotiating the perfect SAFE get you to $10K MRR?

Negotiating the perfect SAFE won't matter if your startup runs out of cash. Protecting your equity is just step one — now you have to actually build a product people pay for, ideally pushing toward that first $10K MRR. Good terms don't acquire customers.

FAQ
  • You:
    Why do investors push for a post-money SAFE instead of pre-money?
    Guide:
    A post-money SAFE locks in the investor's exact ownership percentage at the time of signing. This protects them entirely from dilution caused by any other SAFEs you issue before the priced round, forcing the founders to absorb nearly all of that dilution.
  • You:
    Can I issue a SAFE with no valuation cap?
    Guide:
    Yes, an uncapped SAFE typically relies solely on a discount rate (usually 20% to 25%) to reward the investor. However, many early investors refuse uncapped SAFEs because they want guaranteed maximum pricing if the company valuation skyrockets before the next round.
