Series B Readiness Checklist Calculator 2026
Series B in 2026 typically requires $5M+ ARR, 80%+ YoY growth, 110%+ NRR, burn multiple ≤1.5x, and CAC payback ≤18 months. This tool scores your startup across all six criteria and produces a readiness grade with VC benchmark commentary.
2026 Series B Benchmarks
The bar moved up. 2021 Series B: $3M ARR, 60% growth was enough. 2026: $5-8M ARR, 80%+ growth, profitable unit economics. Reasons: capital cost is higher, VC funds are smaller per check, and bridge-round stigma forced founders to wait until truly ready.
Why All Six Metrics Matter
ARR alone isn't enough — you need growth to prove demand, NRR to prove product-fit, burn multiple to prove capital efficiency, payback to prove sales motion, and gross margin to prove the business scales without margin erosion. Missing any one creates investor doubt.
What To Do If Below Threshold
Three paths: (1) Bridge round at flat valuation to extend runway 6-12 months. (2) Extension Series A from existing investors. (3) Recap with new lead at lower valuation. Each has trade-offs; founders who try to push a weak Series B typically end up with worse terms than a smart bridge.
