Why runway matters for fundraising

Fundraising typically takes three to six months from first meeting to money in the bank. Founders who start raising with less than six months of runway negotiate from a weak position, so the usual advice is to start when you still have nine or more months left.

Most seed rounds are sized to give 18 to 24 months of runway: enough time to hit the milestones that justify the next round, plus a buffer for the next raise itself.
