AI Startup Runway Calculator

Calculate runway against real ai benchmarks. The relevant benchmark here is 12-18 months — inference cost moves fast.

Typical starting inputs

This page starts from $150,000/mo burn, $40,000/mo revenue, 52% gross margin, and 18% monthly growth — adjust them to match your books.

What AI founders should watch

  • Inference cost per query is a moving target. Lock contracts where possible.
  • Gross margin under 50% triggers VC concern — model an aggressive cost-down path.
  • Foundation model dependency is a real risk; plan for multi-vendor fallback.

Burn multiple

AI startups are often evaluated on revenue growth + gross margin trajectory together. 4x year-over-year growth with margins improving from 40% to 60% is fundable.

When to raise

AI Series A rounds are uniquely sensitive to gross margin and inference cost trajectory. Expect a deeper gross margin diligence than SaaS.

What usually goes wrong

  • Inference cost per call drifting up.
  • Foundation model price increases or API deprecation.
  • Fast-following competitors with similar prompts.
