Sample Output
This is an example of what AI produces when you use this template.
Revenue Build-Up to Series B
Starting at $1.2M ARR with 12 percent MoM growth. Month 6: $2.37M ARR. Month 12: $4.68M ARR. Month 18: $9.23M ARR — Series B target of $8M achieved in month 15. Revenue composition: existing customer base growing at 118 percent NRR contributes $3.1M of the $8M target, new logo acquisition contributes $4.9M, and professional services at 15 percent attach rate contributes $0.2M. The model assumes the $5M Series A extends the runway to 22 months, providing a 7-month buffer beyond the Series B milestone.
Capital Efficiency Analysis
ARR per employee: current $100K ($1.2M / 12 employees). Post-Series A with 25 total employees at month 12: $4.68M / 25 = $187K ARR per employee — above the $150K benchmark for efficient SaaS. Burn multiple: at $5M raised and $2.8M ARR added over 12 months, the burn multiple is 1.8x — well below the 2.5x threshold that concerns investors. Cash-to-cash efficiency: $5M in capital generates $3.48M in incremental ARR before reaching Series B, representing a 0.7 capital efficiency ratio.
