The cost of priced rounds is often brought up as a reason to choose a SAFE. Why are priced rounds so expensive in the first place?
The short answer: lawyer time.
When you do a priced round, you have to go in and change many aspects of a company's legal structure. For example, the documents drafted in a priced round may include amendments to the charter, a voting agreement, a stock purchase agreement, a right of first refusal agreement, a shareholder agreement. Drafting the legal docs for a convertible note or SAFE is less intensive and time consuming.
