TL;DR

Series A investors are looking for evidence of product-market fit and a repeatable go-to-market motion. Key metrics: ARR ($1–3M+), MoM growth (15–20%+), NRR (100%+), CAC payback (< 18 months).

The Series A Benchmark

Only 40–50% of seed-funded companies raise a Series A (CB Insights). The primary reason for failure: insufficient traction.

Key Series A Metrics

ARR (Annual Recurring Revenue)

Benchmark: $1–3M ARR is the typical threshold. Top-tier companies raise at $500K–$1M with exceptional growth.

What matters more: Growth rate and trajectory.

MoM Growth Rate

Benchmark: 15–20%+ MoM growth (consistent, not lumpy)

A company growing 20% MoM will 8x in 12 months.

Net Revenue Retention (NRR)

Benchmark: 100%+ minimum; 110–120%+ is strong

NRR > 100% means the business grows even without new customers — the strongest PMF signal.

CAC Payback Period

Benchmark: less than 18 months for Series A. Less than 12 months is strong

Gross Margin

Benchmark: 60%+ for SaaS. 70%+ is strong

Churn Rate

Benchmark: < 2% monthly (< 24% annual) for SMB SaaS. < 1% for mid-market/enterprise

The Series A Narrative

Beyond metrics, investors want: Why now? Why you? What's the path to $100M ARR?

Key Takeaways

Key Takeaways
  • Series A benchmark: $1–3M ARR, 15–20%+ MoM growth, NRR greater than 100%, CAC payback less than 18 months.
  • NRR greater than 100% is the strongest PMF signal.
  • Growth rate matters more than absolute ARR — trajectory is everything.
  • Only 40–50% of seed-funded companies raise a Series A — focus on metrics before raising.
  • Beyond metrics, investors want a compelling narrative: why now, why you, path to $100M ARR.
