Pro Tips
The 6-Month Rule: Start raising when you have 6+ months runway. Investors want progress, not desperation.
Runway vs. Growth: Growing revenue buys runway. 10% month-over-month growth turns 12 months into ~18 months of runway.
Benchmark by Stage: Pre-seed: 12-18 months. Seed: 18-24 months. Series A: 24+ months.
Variable Expenses: Add a 15-20% buffer to projected burn rate. Most startups underestimate expenses.
