Understanding SAFE Agreements: A Founder's Guide

SAFE agreements have become the standard for early-stage startup fundraising. Created by Y Combinator in 2013, they offer a simpler, faster alternative to convertible notes.

What is a SAFE?

A SAFE (Simple Agreement for Future Equity) is an investment contract between a startup and an investor. Unlike traditional equity investments, SAFEs don't give investors immediate ownership. Instead, they convert to equity in a future financing round, typically the Series A.

How SAFEs Work

An investor gives you money now in exchange for the right to receive shares later. Key terms include:

• Valuation Cap: Maximum company value used to calculate the investor's share price
• Discount Rate: Percentage discount off the next round's share price (typically 10-20%)
• Pro Rata Rights: Option to invest in future rounds to maintain ownership percentage
• Most Favored Nation (MFN): Protection if better terms are offered to other investors

SAFE vs Convertible Notes

SAFEs differ from convertible notes in several key ways:

• No interest: SAFEs don't accrue interest like convertible notes
• No maturity date: SAFEs don't expire or require repayment
• Simple documentation: Usually just 5 pages vs 10+ for notes
• No debt: SAFEs aren't loans, so no legal complications around debt

Impact on Your Cap Table

SAFEs affect your cap table in important ways:

• They dilute existing shareholders when they convert
• Multiple SAFEs with different caps create complexity
• You need to model conversion scenarios before raising priced rounds
• Pre-money vs post-money SAFEs have different dilution impacts
