    Common mistakes when calculating runway for Early-Stage Startup

    • Spending on marketing before PMF
    • Hiring expensive senior people before you have a product
    • Having no clear milestone plan to justify the next round

    Frequently asked questions

    How much runway should I have when I close my seed round?

    At least 18 months. Ideally 24, because raising the next round takes 3-6 months, and you need another 12-15 to hit the milestones that justify it.

    What do I do if my runway drops below 9 months?

    You have 3 options: cut burn aggressively, raise a bridge round, or accelerate revenue. All three at once is ideal. Never wait until you have 3 months left to act — by then it's too late.
