Frequently Asked Questions

What is startup runway?

Runway is the number of months your startup can operate before running out of cash. It is calculated by dividing your current cash balance by your net monthly burn rate (expenses minus revenue).

When should I start fundraising?

Most founders should start fundraising when they have 6-9 months of runway remaining. The typical fundraising process takes 3-6 months from first meeting to money in the bank.

What is a healthy burn rate?

A healthy burn rate depends on your stage. Pre-seed startups typically burn $20K-$50K/month, seed-stage $50K-$150K/month, and Series A companies $150K-$500K/month. The key metric is runway relative to your next milestone.

How does revenue growth affect runway?

Revenue growth extends your runway by reducing net burn over time. If your monthly revenue is growing, your effective runway is longer than a simple cash-divided-by-burn calculation suggests.
