Runway (months)—
18 months of runway is the safety floor
The convention in venture-backed startups: never let runway drop below 18 months. Below 12 months, you are fundraising under duress and accepting worse terms. Below 6 months, you are likely down to bridge rounds and tough conversations. Track runway weekly, not monthly.
