Convertible notes and SAFE (Simple Agreement for Future Equity) agreements are popular startup funding instruments that allow companies to raise capital quickly while deferring valuation discussions until a later equity round. These flexible instruments have become essential tools in early-stage startup financing, offering benefits to both entrepreneurs and investors.
Overview of Convertible Instruments
Convertible instruments are financial securities that begin as one type of investment (typically debt or a contractual right) and convert into equity under specified conditions. They allow startups to raise capital without immediately determining a company valuation, making fundraising faster and more flexible.
Why Use Convertible Instruments?
- Speed: Faster than negotiating equity rounds with complex terms
- Valuation Deferral: Avoid setting valuation until more data is available
- Investor Incentives: Provide early investors with conversion benefits
- Lower Legal Costs: Simpler documentation than equity financings
- Bridge Financing: Bridge gap between funding rounds
Common Use Cases
- Seed funding before formal Series A round
- Bridge financing between equity rounds
- Strategic investor participation
- Employee stock option plan alternatives
- Friends and family funding rounds
Convertible Notes
What Are Convertible Notes?
A convertible note is a debt instrument that converts into equity upon the occurrence of specified triggering events, typically a qualified financing round. Until conversion, it functions as a loan with interest that accrues over time.
Key Terms and Features
Essential Components
- • Principal Amount: The investment amount
- • Interest Rate: Annual interest rate (typically 6-8%)
- • Maturity Date: When the note must be repaid (usually 18-24 months)
- • Conversion Triggers: Events that cause conversion to equity
- • Conversion Discount: Discount rate for converting investors
- • Valuation Cap: Maximum valuation for conversion purposes
Conversion Mechanics
Convertible notes typically convert in the following scenarios:
- Qualified Financing: Conversion upon raising minimum amount in equity round
- Maturity: Automatic conversion or repayment at maturity date
- Change of Control: Conversion upon sale or merger of company
- Optional Conversion: Investor choice to convert under certain conditions
Conversion Discount
The conversion discount (typically 15-25%) rewards early investors by allowing them to convert at a lower price than new investors in the triggering round.
Conversion Example
Scenario: $100,000 convertible note with 20% discount
- Series A price per share: $2.00
- Conversion price with discount: $1.60 ($2.00 × 80%)
- Shares received: 62,500 ($100,000 ÷ $1.60)
- vs. New investor shares: 50,000 ($100,000 ÷ $2.00)
Valuation Cap
A valuation cap sets a maximum company valuation for conversion purposes, protecting investors if the company achieves a very high valuation in the next round.
SAFE Agreements
What Is a SAFE?
A Simple Agreement for Future Equity (SAFE) is an investment contract that provides the right to receive equity in future financing rounds. Unlike convertible notes, SAFEs are not debt instruments and do not accrue interest or have maturity dates.
SAFE Characteristics
- Not Debt: No interest rate or maturity date
- Conversion Rights: Right to convert to equity in future rounds
- Simpler Documentation: Standardized, streamlined legal documents
- Founder Friendly: No repayment obligation or control rights
- Flexible Terms: Various SAFE types for different scenarios
Types of SAFEs
| SAFE Type | Valuation Cap | Discount | Best For |
|---|
| Cap, No Discount | Yes | No | Early stage, uncertain timing |
| Discount, No Cap | No | Yes | Later stage, near equity round |
| Cap and Discount | Yes | Yes | Maximum investor protection |
| MFN (Most Favored Nation) | No | No | Quick closing, minimal terms |
SAFE Conversion Events
- Equity Financing: Sale of preferred stock above minimum threshold
- Liquidity Event: Company sale, merger, or IPO
- Dissolution Event: Company dissolution or winding up

Key Terms and Mechanics
Valuation Cap Mechanics
The valuation cap protects investors by setting a maximum company valuation for conversion purposes:
Cap Example

- Scenario 1: Series A at $4M pre-money → Convert at $4M (no cap effect)
- Scenario 2: Series A at $10M pre-money → Convert at $5M cap
- Ownership: $500K ÷ $5M = 10% vs. 5% without cap
