# Real Options Theory / VC Stage-Gating

**Prerequisite knowledge:** Venture-capital investment logic — specifically buying **'the right, but not the obligation'** to invest further (**real options theory**) contingent on hitting milestones or acquiring new information.

**Why it's needed:** It is the intellectual foundation for [[concept-optionality]], [[action-stage-gate-capital]], and the [[quote-vc-logic|VC-logic question]]. Frank Knight's risk/uncertainty distinction ([[concept-risk-vs-uncertainty]]) explains *why* options have value when distributions are unknown.
