SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve? Founders and finance teams struggle to build credible financial projections for fundraising and planning, often producing overly optimistic revenue forecasts, underestimating costs, or ignoring cash flow timing. This Skill provides a structured methodology for creating investor-ready 3-5 year financial models grounded in realistic assumptions. ## Core Features & Use Cases - Cohort-Based Revenue Modeling: Project MRR and ARR from customer acquisition, retention curves, and ARPU rather than top-down guesses. - Cost Structure & Headcount Planning: Model COGS, S&M, R&D, and G&A with fully-loaded compensation and role-based hiring plans. - Cash Flow & Runway Analysis: Calculate monthly burn rate, runway, and funding needs with proper cash timing. - Three-Scenario Framework: Build conservative (P10), base (P50), and optimistic (P90) scenarios for board reporting and cash management. - Use Case: A seed-stage SaaS founder preparing for a Series A raise uses this Skill to model $500K to $8M ARR growth over three years, validate unit economics (LTV/CAC > 3), and determine a $5M raise covers 24 months of runway. ## Quick Start Ask the AI to build a 3-year financial model for your startup including cohort-based revenue projections, headcount plan, burn rate, runway, and conservative/base/optimistic scenarios.

FAQPage Schema
How do I build a financial model for a startup?

Start by defining your business model and revenue drivers, then project revenue using cohort-based acquisition and retention. Model costs across COGS, S&M, R&D, and G&A, plan headcount with fully-loaded compensation, and calculate monthly cash flow to determine burn rate and runway.

How to calculate startup runway and burn rate?

Monthly burn equals monthly revenue minus monthly expenses, and runway equals current cash balance divided by monthly burn. Model cash flow monthly since revenue collection timing differs from expense payment timing.

What is cohort-based revenue modeling for SaaS?

Cohort-based modeling calculates MRR as the sum of each cohort's size multiplied by its retention rate and ARPU. This produces more accurate projections than top-down growth rates because it accounts for churn and expansion over time.

What financial metrics do investors look for in a seed or Series A model?

Investors focus on LTV/CAC ratio above 3, CAC payback under 12-18 months, burn multiple under 2.0, gross margins of 75-85% for SaaS, and net revenue retention of 100-120%. Growth rates around 3x in Year 2 and 2x in Year 3 are considered achievable.

What are common mistakes in startup financial projections?

Common pitfalls include overly optimistic revenue assumptions, underestimating costs by ignoring fully-loaded compensation, confusing revenue with cash timing, static headcount plans that ignore hiring ramp time, and failing to model conservative downside scenarios.
