What's the difference between a valuation cap and a discount on a SAFE?

The short answer

A cap sets the maximum valuation at which your SAFE converts, protecting the investor's upside if you raise your next round at a high price; a discount just gives them a percentage off that round's price. Caps matter far more than discounts in practice. Model how both convert before you agree, because a low cap plus stacked SAFEs can quietly gut your ownership.
