The article discusses the implications of dilution in startup funding, particularly focusing on SAFEs (Simple Agreements for Future Equity) and how they can lead to unexpected ownership loss for founders if not managed carefully. It highlights the importance of understanding dilution over multiple funding rounds and the potential pitfalls of relying too heavily on SAFEs without converting to priced rounds.

Understanding the differences between SAFEs (Simple Agreements for Future Equity) and convertible notes is crucial for founders when deciding on fundraising instruments. SAFEs are non-debt instruments that convert to equity without a repayment timeline, while convertible notes are loans with interest and a maturity date, requiring repayment if not converted. Founders should choose the instrument that aligns with investor preferences and allows for quick execution to focus on business growth.
