Most pre-seed startups need 12-18 months of runway—enough capital to reach a meaningful milestone (product launch, user traction, or revenue) that attracts seed investors. The exact amount depends on burn rate, team size, and market conditions.
Calculating Your Runway
Runway = Available capital ÷ Monthly burn rate. A startup with $200K and $15K monthly expenses has roughly 13 months. Calculate conservatively by including all costs: salaries, rent, software, marketing, and a 20% contingency buffer.
Pre-seed teams typically operate lean:
- Founder-only stage: $50K-$150K covers 12-18 months
- Small team (2-3 people): $150K-$400K provides adequate runway
- Larger pre-seed teams: $400K-$750K supports 12-18 months
Why 12-18 Months?
This timeframe allows startups to validate product-market fit, acquire initial customers, and demonstrate traction—the metrics seed investors evaluate. Shorter runways force premature fundraising or shutdown; longer runways encourage inefficient spending.
Extending Your Runway
Reduce burn rate by:
- Bootstrapping revenue early (even small amounts matter)
- Using free or low-cost tools and services
- Hiring contractors instead of full-time employees
- Negotiating favorable vendor terms
- Securing grants or competitions
Fundraising Timeline
Begin seed fundraising conversations 6-9 months into your runway. This timing allows 3-6 months for investor meetings and due diligence before capital depletes. Starting too early wastes investor attention; starting too late creates desperation that weakens negotiating position.
Track runway monthly and adjust spending based on progress toward milestones.
