Why It Matters
The discount rate serves as one of the primary incentives for investors to participate in early financing rounds using convertible instruments rather than waiting for a priced equity round. When a startup raises $2 million at a $10 million valuation and previous note holders have a 20% discount, they convert at an effective $8 million valuation—acquiring shares at $0.80 each while new investors pay $1.00 per share. This mechanism ensures early believers receive tangible compensation for bearing the uncertainty of pre-revenue or early-traction stages. For founders, offering an appropriate discount helps close bridge financing without immediately setting a valuation, preserving flexibility during rapid growth phases.
Example
A seed investor provides $100,000 to a SaaS startup via a convertible note with a 20% discount and no valuation cap. Eighteen months later, the company raises a Series A at a $15 million pre-money valuation, selling shares at $1.50 each. The seed investor's note converts at $1.20 per share (20% discount applied), giving them approximately 83,333 shares instead of the 66,667 shares they would receive at the full Series A price. This 25% increase in share count (the inverse of the 20% discount) represents real economic value—if the company eventually exits at $60 million, that difference translates to roughly $25,000 in additional proceeds from their original $100,000 investment.
