Runway Is a State of Mind Until It Isn't
The strength of your runway was decided long before the day you look up and see how little of it is left.
In December of 2020, a friend referred me into a startup in the Pacific Northwest doing genuinely exciting work in cloud security. Two ex-Microsoft product executives, Ivy League pedigrees, a clean high-growth story. They had closed their angel and friends-and-family rounds and were bridging to a major institutional round. Because of an inside connection, I was offered the chance to invest at the pre-round valuation. Aside from a few flags on culture, I was comfortable. The big round closed a year later, right on schedule.
Fast forward to the middle of 2024. Every individual investor, myself included, receives a certified letter with this message, and I’m paraphrasing: “The company is finalizing a sale to a larger software firm, at a fraction of the valuation we had been discussing with our investors a few months earlier. This sale is being forced due to exhaustion of our cash reserves and the need to continue serving our customers”. 80% of our investment capital evaporated!
I won’t go into the shock factor and the legal drama that ensued with the investors, needless to say, it was ugly. Here is what happened that led to this. The executive team aligned the entire raise to a single growth bet: push the platform into the small-business market. They hired a direct sales team of nearly a hundred people, ran a smile-and-dial campaign, and burned through roughly $75 million in two and a half years. A runway built to carry the company to an IPO simply evaporated. Not from a market shock. From decisions, made in full view of the board, that nobody stopped.
Regardless of how large the number in the bank looks, you are never safe.
I am not going to separate personal runway from business runway, because the mindset is identical. The strength of your runway is not set by your bank balance. It is set by the decisions and behaviors you put in place, or fail to, long before the moment you realize it is far shorter than you ever imagined.
The balance is a lagging indicator. Your behavior is the leading one.
This is not only my read of it. In its analysis of 431 startups that shut down, CB Insights reports that “ran out of capital” appears in roughly 70% of the post-mortems. But it is careful to name that number for what it is: the last thing that happens, not the reason it happens. The real killers sit upstream, in leadership, in product design pivots, in decision timing, in unit economics that never worked. The empty account is where the story ends. It is not where it went wrong.
I’ve lived both sides of this. Across my own companies, I ran cash cycles that swung from comfortable to frightening, the kind that keep you awake rehearsing how you will make payroll. And the lean stretches arrive faster than you expect. In the early years I had no contingency plan for the cash-scarce scenario, and in hindsight that absence is what drove most of my years of stress. I had no runway calculator. I had no discipline or cadence to evaluate runway length and risk. I had set no signals to raise an alarm before the problem was already on top of me. Had I done any of that, my stress, and my decisions under pressure, would have been materially different.
The decisions the good times let you postpone
Hiring too fast. For me this is the original sin. Bringing people on without a clear role or a strategy behind the hire, on the false confidence that revenue would keep pace. In one case for me, that meant staffing ahead of a half-baked plan to sell into the enterprise with an offer that was hard to position and thin on value.
Not raising prices. We held ours flat while competitors raised theirs, on the theory that stable pricing would pull their customers over to us. It didn’t. That’s not how buyers behave, and the price you never raise is revenue you never recover.
Holding a low-margin client for the logo. We won a contract with a large federal agency almost entirely on price, betting the reference would open better-margin doors across government. Hope is not a strategy. I should have severed it after year one. I kept it for years, and it dragged on our financial health the entire time.
None of these felt urgent while the balance looked fine. That’s precisely the trap.
Then the wall
Here’s the part nobody prepared me for. Runway didn’t slowly recede. It hit us like a wall and left us wondering how we missed every sign.
The move from comfort to panic is always faster than you expect, because the decisions you did not act on compound. When they finally come due, a single month of cash compression can cut your runway by half, sometimes more. That is the moment you understand you should have moved faster on the unprofitable client, and way slower on the subpar product offer. Same lesson, opposite directions. Both were behaviors I should have thought through more deliberstely. Both were wrong.
None of this means the number doesn’t matter. Watching your cash closely is essential. It’s how you make adjustments before you’re forced into them, and how you prepare to move quickly when the moment calls for adjustment; cuts, personnel reductions, or whatever the case may be. But this is only a fraction of why you watch, and I learned it the hard way. Failure does not stem from not knowing your balance. It stems from watching it fall and still not changing your behavior.
What to do Monday
Build your burn calculator and your extension planner.
And make the one list you have been avoiding: the decisions you already know you should make. The hire to reverse. The price to raise. The client to release. Then act on one of them this week, not later. Later is where runway goes to die.
I built the runway calculator I wish I'd had in those sleepless years. It shows you the real gap in about five minutes, across the scenarios that actually matter, not the single optimistic one most founders run.
Until next week,
George
