Fundraising narratives are stronger when the operating assumptions are visible
A blank spreadsheet slows planning, while an unexamined model can hide the assumptions that drive the story. This template gives you a structured starting point with clear input cells, linked outputs, and room to stress-test cases.
Pre-seed and seed founders, operators, and early-stage teams preparing an operating plan or a finance conversation.
Practical by designWork from real inputs, real evidence, and visible next actions.
Clear about limitsUse the resource as a system for better work, not as a promise of outcomes.
Ready to adaptStart with the structure, then fit it to your context, tools, and professional judgment.
A working model you can inspect, stress-test, and explain
Build month by month
Plan 36 months of revenue, costs, headcount, P&L, cash runway, and fundraising timing.
Separate inputs from outputs
Use blue assumption cells and review the formulas instead of treating the workbook as a black box.
Prepare a finance conversation

How to use it
Edit the blue cells, review the formulas, stress-test downside and upside cases, and replace every placeholder with your actual operating data before sharing externally.
Important: This is a planning template, not accounting, tax, legal, valuation, investment, or fundraising advice. Validate important decisions and investor materials with a qualified finance professional.
A few useful boundaries before you begin.
Is this an accounting, valuation, or fundraising model?
It is a starter operating model for planning. It is not accounting, tax, legal, valuation, investment, or fundraising advice.
Can I share it with investors immediately?
Replace every placeholder, review formulas, validate assumptions, and have a qualified finance professional review important materials first.
What makes it beginner-friendly?
The workbook starts with a structured 36-month layout, visible input cells, linked outputs, and a quick-start guide rather than a blank sheet.
