This document discusses factors to consider when determining how much funding to raise for a startup. It recommends calculating needs based on milestones and assumptions, and either raising just what is needed close to need, or raising more than needed well in advance. Timing is important to plan. It also suggests defining milestones like product beta, customers, and 18 months of runway. Non-financial proofs like metrics, customers, and execution should be evaluated along with financial projections.
