What is a good startup runway?

Most investors recommend 18–24 months of runway. This gives you enough time to hit milestones, run a fundraising process, and handle unexpected delays.

How do I extend my startup runway?

Reduce monthly burn by cutting non-essential costs, increasing revenue, or raising additional capital. Renegotiating vendor contracts and pausing hiring are common tactics.
