Damian Maggio breaks down why founders misjudge their startup runway and shares simple habits to track cash burn correctly before it puts the business at risk. Most founders run out of cash before they run out of ideas. That is the hard truth behind thousands of startup closures every year. A founder can have a great product, loyal users, and a strong team. The business can still shut down because the money ran out faster than planned. The warning sign was there. It just got read wrong from the start. DamianMaggio, a financial services professional with decades of experience in fund management, has watched this pattern show up again and again across the finance world. The real problem is rarely a lack of effort. It is a lack of clear thinking about one simple number: runway.
Let’s explore why so many founders get this number wrong and what it takes to read it the right way.
Quick Answer: Founders get runway wrong because they treat it as a fixed number, not a moving one. The three biggest errors are: counting investor interest as real cash, using an old burn rate that no longer matches real spending, and ignoring the market clock that runs next to the cash clock. The fix is simple. Check burn rate every month. Only count cash that has truly landed. Tie spending to real goals, not just months left.
What Runway Really Means
Runway is how long a business can keep running before the cash in the bank hits zero. The math sounds easy. Take the cash you have and divide it by what you spend each month. That gives you the number of months left.
But this simple math hides a real problem. Founders often treat runway like a phone battery, a fixed number that just counts down. In real life, runway moves. It shrinks when spending goes up. It stretches when more money comes in. It can drop fast if one big client walks away. Treating the runway as a fixed number is the first mistake. It leads to many more.
There is also a gap between gross burn and net burn that trips up many founders. Gross burn is all the money spent in a month. Net burn is money spent minus money earned that same month. A startup with rising sales might have more real runway than its gross burn shows. A startup losing customers might be burning cash faster than its old numbers say. Mixing up these two numbers is often where the first wrong guess starts.
Mistake 1: Counting Interest as Commitment
Many founders feel relieved the moment an investor says, “This looks promising.” That relief often gets baked into the cash plan before any money shows up. A founder might spend more or skip tough cuts because a deal feels close.
But interest is not commitment. A term sheet is a commitment. Money in the bank is commitment. Friendly chats and follow-up calls are not. Founders who mix up the two end up with a runway that looks longer on paper than it really is.
Mistake 2: Using One Burn Rate Number Forever
Burn rate changes every month. But many founders calculate it once and stop checking. A team that hires three people in March will spend faster in April, even if the old plan said otherwise.
A better way is to look at the last three months of spending, not just one. This smooths out one-time costs and gives a clearer average. Founders who only check this number once every few months are often shocked by how much the picture has changed.
Mistake 3: Ignoring the Market Window
Cash is not the only clock running. The market has its own clock too. Competitors raise money. What customers want can shift fast. A product that feels new today can feel old in a year if a faster rival shows up.
This is why runway should never be measured by bank balance alone. Financial professionals like Damian Maggio often point to this wider view when discussing financial discipline in venture settings. A startup is not just racing its own spending. It is racing the speed of the market around it.
How Smart Founders Actually Track Runway
Founders who get this right do three things differently:
- They check burn rate every single month, not once every few months, so surprises get caught early
- They kept the confirmed money and hoped for more money in two separate piles
- They tie runway to real goals, like signing ten new customers, not just months left on a clock
This shift changes everything. Instead of asking “how long can we survive,” the better question is “what can we prove before the money runs low?” That one change in thinking often separates startups that raise on strong terms from those that raise out of fear.
The Real Cost of Getting It Wrong
| Mistake | What Founders Think | What Actually Happens |
| Counting verbal interest as funding | The deal is basically done | Funds may never arrive |
| Using an outdated burn rate | Spending matches the plan | Costs have quietly increased |
| Ignoring market timing | Cash is the only deadline | Competitors move first |
| Tracking runway quarterly | Enough warning time exists | Problems are caught too late |
The table above shows a clear pattern. Every mistake leads to the same place. The founder thinks they have more time than they really do. By the time the truth comes out, there is less room left to fix it.
Why This Matters More in 2026
Funding cycles have gotten longer. Carta data shows the wait between a seed round and a Series A round is now about 616 days, or close to 20 months. That is more than two months longer than the wait time just two years ago. This means startups must now plan for 20 months of runway or more, not the 12 months many founders used to assume was enough.
This also means founders cannot treat cash planning as a one-time task. Cash flow needs the same care as building the product or growing customers. A great product with a confused cash plan still leads to a business in trouble.
Building Better Financial Habits Early
Good runway tracking does not need a finance degree. It needs honesty and a routine. A few simple habits make a real difference over time.
- Check cash balance and spending on the same day every month, like a meeting that never gets skipped
- Ask before every big hire or cost: Will this shorten our runway in a way we can handle
- Share real numbers with the whole team, not just the founder, so everyone feels the urgency
These habits sound small. But they stop the kind of surprise that pushes a company into a rushed and weak funding round.
Final Thoughts
Runway is not just a finance term. It shows how clearly a founder sees their own business. Mixing up hope with real cash, ignoring rising costs, and forgetting the market clock all lead to the same painful place. Damian Maggio’s work in fund management reflects this same idea. Businesses do better when their financial picture stays honest and current, not when it stays comfortable. Founders who treat runway as a living number, not a fixed countdown, give themselves the best shot at growing on their own terms, not out of fear.
