Runway Planner Skill

Runway is the number that decides everything else. This skill turns cash and burn into months of runway, a default-alive/dead verdict (à la Paul Graham), and the dated triggers for when to raise or cut — so the founder isn't surprised. Not financial advice; confirm with your finance lead.

Working from a brief

Given partial numbers, do the full calculation anyway with labelled illustrative figures where needed. Show the arithmetic. Never leave it as "[calculate runway]."

Required Inputs

Ask for (if not already provided), else use clearly-labelled illustrative numbers:

• Cash in bank today
• Monthly net burn (gross burn minus revenue) and whether it's growing
• Revenue today and its growth rate (if any)
• Planned changes — hires, spend increases, or cuts being considered
• Context — when they last raised, what they're optimising for
