Who This Helps
This is for growth marketers tired of asking "how long does the cash last?" You need a clear number to plan campaigns without stressing the founder. The Founder Finance Basics Mission Pack shows you how to build that model, specifically using the Runway Forecast mission.
Mini Case
Ben's revenue was up 15% last quarter, but his cash balance was flat. He was manually updating a spreadsheet every Sunday night, which was already outdated by Monday's standup. He automated his key metrics—like monthly burn and revenue—into a simple dashboard. Now, his runway forecast updates daily. He saw his safe runway dip from 9 to 7 months, which triggered a calm conversation about pacing new hires, not a panic.
Do This Now (5 Steps)
- List your 3 core cash metrics: Monthly Recurring Revenue, Gross Burn, and Current Cash.
- Find where this data lives (Stripe, your bank feed, your payroll system).
- Connect these sources to a simple dashboard tool. Let an AI assistant help map the fields if the labels are messy—this saves you hours of manual mapping.
- Build one calculation: Runway (in months) = Current Cash / Monthly Net Burn.
- Set a weekly calendar alert to review this single number and the trend line. That's your new truth.
Avoid These Traps
- Mixing Channels with Cash: Don't blend your CAC payback analysis into this model. Runway is about survival speed, not marketing efficiency. Keep them separate.
- Over-Engineering: Your first version needs just 3 data points. Don't try to model 12 different scenarios on day one.
- Static Reporting: If your report is a PDF you email, it's a fossil. The value is in the live connection.
- Ignoring the Trend: A 12-month runway shrinking to 10 months over 4 weeks is a louder signal than the static number.
- Forgetting the 'Why': The goal isn't a pretty chart. It's to answer: "Can we afford this new channel test next quarter?"
- Doing It Alone: Finance feels scary. Use the mission pack's structure—like the Hiring vs Runway Stress Test—to frame talks with your founder.
- Guessing at Burn: Use actual bank outflows, not budgeted amounts. Reality is your best teacher, and it's often surprising.
- Waiting for Perfection: A slightly wrong live number is more useful than a perfect old one. Just start.
Your Win by Friday
You'll replace "I think we have about 8 months of runway" with "Our live model shows 7.2 months based on yesterday's close." You'll have one clear, auto-updating number that informs your growth bets. No more Sunday night spreadsheet dread. You'll look prepared, not panicked. Now go make your data work for you, so you can focus on the fun part—growth.
