Choosing the proper financing structure is a critical decision for venture-backed startups. Founders must understand how different funding instruments—such as SAFE (Simple Agreement for Future Equity), Convertible Notes, and Equity—impact ownership, valuation, and future fundraising. In this post, we’ll break down these three common financing tools, helping you decide which one is the best fit for your startup’s growth stage.
SAFE vs. Convertible Note vs. Equity - what's the difference?
1. SAFE (Simple Agreement for Future Equity)
A SAFE is a financing agreement that gives investors the right to convert their investment into equity during a future round, usually when a priced round occurs (like a Series A).
Pros:
Founder-friendly: No immediate dilution or debt obligations.
Simple terms: Fewer legal complexities and lower administrative costs.
No maturity date: Reduces pressure to achieve milestones within strict timelines.
Cons:
Uncertain valuation: Since SAFEs convert in the future, there’s ambiguity about the final percentage of ownership.
Limited legal protections for investors: SAFEs offer fewer rights than debt or equity investments.
When to Use:
SAFEs are ideal in the early stages (pre-seed or seed rounds) when a startup isn’t ready for a full valuation or complex term sheets.
2. Convertible Notes
Convertible notes function as loans that convert into equity upon a future financing event. Investors loan money expecting it to convert into shares at a discount once the startup raises a priced round.
Pros:
Debt with conversion flexibility: Investors are protected with a loan that converts into equity later.
Discounted equity: Investors typically receive a discount upon conversion, offering an upside for early risk.
Bridge financing tool: Useful for startups between funding rounds.
Cons:
Maturity date and interest: Convertible notes accrue interest and mature, adding financial pressure.
Potentially complex: Legal structures can involve more negotiation than SAFEs.
When to Use:
Convertible notes are commonly used when a startup needs bridge financing or a short-term injection of funds before closing a larger round.
3. Equity Financing
Equity financing involves selling shares of the company to investors in exchange for capital. This is usually part of a larger, more formal round (e.g., Series A or B).
Pros:
Established valuation: The startup and investors agree on a valuation, providing transparency on ownership.
Long-term capital: No repayment obligations or maturity dates.
Stronger investor alignment: Investors gain a direct stake in the company, aligning their interests with the business’s success.
Cons:
Dilution: Founders lose ownership percentage with each round.
Complex and costly: Legal fees and compliance costs are higher compared to SAFEs and convertible notes.
Time-consuming: Equity fundraising takes longer to finalize.
When to Use:
Equity financing is best suited for startups with established traction and a clear valuation, typically in Series A or later rounds.
Choosing the Right Option for Your Startup
Each financing instrument serves a distinct purpose, depending on the stage and needs of your business:
Pre-Seed/Seed Stage: SAFEs or convertible notes provide flexibility with minimal upfront complexity.
Bridge Financing: Convertible notes offer short-term solutions while waiting to close a major round.
Series A and Beyond: Equity financing is optimal for more mature startups ready to establish clear valuations and align with strategic investors.
Final Thoughts
Navigating the nuances between SAFE vs. Convertible Note vs. Equity, can be challenging for founders. It’s essential to weigh the pros and cons of each instrument and align your choice with your business goals. Partnering with experienced financial advisors ensures you make the most informed decision and position your company for long-term success.
