Developer Tools Startup Runway Calculator

Calculate runway against real devtools benchmarks. The relevant benchmark here is 18-24 months with strong PLG motion.

Typical starting inputs

This page starts from $90,000/mo burn, $20,000/mo revenue, 80% gross margin, and 14% monthly growth — adjust them to match your books.

What Devtools founders should watch

Bottom-up adoption and weekly active developers matter more than ARR in early stage.
Self-serve to enterprise expansion is the runway extender — design for it from day one.
Open-source contributor community has a measurable revenue impact at Series A.

Burn multiple

Devtools are evaluated on weekly active developers, free-to-paid conversion, and self-serve ARR percentage. Burn multiple targets are similar to SaaS (under 2x).

When to raise

Investors want to see signs of bottom-up adoption: GitHub stars, npm/PyPI downloads, free-to-paid conversion above 2%.

What usually goes wrong

Single-platform dependency (e.g., GitHub-only).
Free user growth without paid conversion.
Enterprise sales cycle longer than expected.
