Build the annual budget from drivers

Build a {{year}} operating plan for {{company}}. Current: {{revenue, growth rate, headcount, cash, burn, margins}}. Plans: {{hiring, launches, pricing changes}}.

1. Model revenue from drivers, not a growth percentage: pipeline or traffic → conversion → new customers → ARPU → expansion → churn. Show each driver's assumed value and its basis.
2. Build costs bottom-up by team, with fully-loaded headcount costs including timing of hires, and separate committed from discretionary spend.
3. Produce the monthly P&L and cash view, showing runway month by month.
4. Give three scenarios with the driver changes that define them — not just ±20%.
5. Identify the two drivers that dominate the outcome and how sensitive the plan is to each.
6. Name the decision points: at what date and what metric do we accelerate hiring, freeze, or cut? Make the triggers specific.
7. List every assumption I should challenge, flagging the ones that look optimistic given our history.

Use my real numbers. Where you have to assume, label it.
