Convertible Note Cap
Last updated
Quick Answer
The maximum valuation at which a convertible note converts into equity, protecting early investors from excessive dilution if the company raises at a very high valuation.
A Convertible Note Cap (or valuation cap) is the maximum effective valuation at which a convertible note will convert into equity in a future priced round. It protects early investors by ensuring they receive a minimum ownership percentage regardless of how high the valuation climbs at the next round. If the priced round valuation exceeds the cap, the note converts at the cap; if the valuation is below the cap, the note converts at the actual round valuation (potentially with an additional discount). The cap functions as a ceiling on the conversion price, effectively giving the note holder a better price per share when the company raises at a high valuation. Caps are typically set at 1.5-3x the implied valuation at the time of the note, reflecting the risk premium early investors take. Notes can have both a cap and a discount, with the investor receiving whichever produces more shares (the better deal).
In Practice
An angel invests $100,000 via a convertible note with a $5 million cap and 20% discount. The startup raises a Series A at $20 million pre-money. Without the cap, the discount would give a $16 million effective valuation. But the cap provides a $5 million effective valuation—much better for the investor. The angel's $100,000 converts at the $5 million cap, giving them 2% ownership instead of the 0.5% they would have received at the $20 million valuation.
Why It Matters
The valuation cap is the single most important economic term in a convertible note. A cap that is too low over-compensates early investors at the expense of founders; one that is too high fails to reward the risk early investors took. Founders and angels should negotiate caps carefully, as they directly determine ownership allocation at conversion.
