The Spreadsheet That Killed My Runway Anxiety

Most founders know their burn rate. Almost none know their danger week. This system tells you both, updates itself every week, and gets more accurate over time.

There is a specific kind of founder anxiety that hits around month 8 of a 12-month runway.

You built the cash flow model in month 1. You have not opened it since. The numbers feel approximately right, until they do not, and by the time you realize the model drifted, you are 6 weeks from a problem you could have seen coming in January.

The 13-week cash flow forecast is the standard tool for this. Every serious founder, CFO, and investor knows the format. Money in, money out, closing bank balance, week by week for a quarter.

The problem is that almost everyone builds it once and lets it go stale.

This kit fixes that. It turns the static spreadsheet into a system that connects to your real money data, updates itself every week, and gets more accurate over time. Runway stops being a number you re-derive every month and becomes a number you trust.

What is inside the full kit:

▫️ The complete 4-tab Excel model, formula-driven with zero manual entry in the model itself

▫️ The Claude setup to interview you, connect to your data sources, and build the initial model

▫️ The weekly update loop that compares last week’s forecast to what actually hit the bank

▫️ The live dashboard with runway gauge, cash chart, fundraise planner, and one-click board PDF

▫️ A full worked example showing the output quality before you install anything
