This document contains slides from a presentation by Paul Sweeney on understanding venture capital term sheets. It provides introductions and then discusses what a term sheet is, when to use convertible notes versus preferred stock, pre-money valuations, option pools, liquidation preferences, and examples of how liquidation preferences work. The key points covered are that a term sheet sets out the proposed terms of an investment but is non-binding, convertible notes are often used for smaller seed investments while preferred stock is more common for larger rounds, and liquidation preferences, option pools, and pre-money valuations are important economic terms that determine the allocation of value between investors and founders.
