Try These Prompts
Build a simple 36-month financial model for my startup. Business model: [describe]. Current cash: [amount]. Starting revenue: [amount]. Include revenue, expenses, burn, runway, and key assumptions.
Create a SaaS revenue forecast using cohort-based assumptions. Use monthly new customers, ARPU, churn, expansion revenue, and pricing tiers. Show MRR, ARR, and retention impact.
Create conservative, base, and optimistic financial scenarios. Vary customer acquisition, churn, contract value, CAC, and hiring timing. Compare runway, funding need, and key metrics.
Add a fundraising plan to my startup model. Include pre-money valuation, investment amount, dilution, use of funds, runway extension, and milestones reached before the next round.
Best Practices
- Start with explicit assumptions for pricing, acquisition, retention, hiring, and cost behavior.
- Separate fixed costs, variable costs, cash timing, and fundraising events.
- Compare outputs against stage benchmarks and update the model when actual results change.
Avoid
- Using one aggressive scenario as the operating plan.
- Treating revenue recognition and cash collection as the same event.
- Ignoring hiring delays, ramp time, benefits, taxes, and attrition.
