What Founders Get Wrong About Personal Runway vs. Company Runway
You can model the company's cash position to the month. Your own? Rarely.
Ask a founder for their company's runway and you get a number to the month, sourced from a model they update weekly. Ask the same founder for their personal runway, how long they could go without a paycheck, and the answer gets vague fast. A shrug. A rough guess. The discipline clearly exists. It just never gets pointed inward.
That gap costs more than it looks like it should. A lot of what gets called "startup stress" is actually personal financial exposure leaking into company judgment: taking a bad deal, raising on bad terms, staying too long in a role that stopped working, all decisions that look like strategy problems but are actually runway problems in disguise.
The Cap Table Desk's take: build the personal model with the same rigor as the company one. Real inputs, honest assumptions, a number you trust enough to act on. Most founders already know how to do this. They have just never turned the spreadsheet on themselves.

Spec Sheet
3 ITEMSWhat is personal runway?
How long you could cover your own expenses without income. The founder equivalent of company runway, applied to your own bank account instead of the business's.
Why do founders model company runway but not personal runway?
Company runway has a board, a deck, and a deadline forcing the discipline. Personal runway has none of that structure, so it stays a rough guess by default.
Does personal runway actually affect company decisions?
Yes. Founders with thin personal runway tend to make worse company decisions under pressure: taking bad deals, raising on bad terms, staying too long in a role that isn't working.
