What Pre-Seed Investors Focus On

Cash runway, burn rate, and the key milestones that unlock your next round. Pre-seed investors focus on whether you have enough runway to prove the thesis.

SaaS Modeling Insight

SaaS models must build a separate cohort tab. Each quarterly vintage tracks its own retention curve. Investors will reconstruct your NRR from cohort data — make sure the math is consistent with your ARR bridge.

SaaS Revenue Model

Subscription-based MRR/ARR model with new customer acquisition, expansion revenue (upsell/cross-sell), and churn tracking. Build separate cohort sheets for each customer acquisition vintage.

Revenue Drivers

  • New MRR from new customers (volume x ACV)
  • Expansion MRR from existing customers (NRR - 1.0 component)
  • Gross churn MRR (churned logo count x average ACV)
  • Net new ARR bridge month-by-month

COGS Structure

  • Cloud infrastructure and hosting (AWS/GCP/Azure)
  • Customer success and onboarding labor
  • Third-party API costs (per usage)
  • Payment processing fees

Unit Economics to Model

  • Customer Acquisition Cost (CAC) by channel
  • CAC Payback Period (months to recover CAC at gross margin)
  • Lifetime Value (LTV) at cohort gross margin
  • LTV:CAC ratio target (3:1 minimum for Series A)
  • Gross Revenue Retention and Net Revenue Retention

Key Model Assumptions

Build every assumption from first principles. Pre-seed investors will ask "how did you get to this number?" for every major line. Have a clear answer that ties back to market research or comparable benchmarks.

  • Monthly new logo adds and churn assumption toggle
  • Expansion revenue rate as % of ARR base
  • Sales productivity ramp (months to full quota)
  • Average ACV by customer segment

Funding Scenarios

Model two scenarios: (1) raising your target amount, (2) raising 70% of target. Show what milestones you hit in each case and when you need to start the next raise.
