What is Runway in a Startup?
“Runway” is literally the strip of pavement a plane uses to take off – and in the startup world, it refers to the number of months your business can keep operating at its current burn rate before it runs out of cash.
It’s like diving with an oxygen tank: if you don’t know how much air you have left, you might not make it back to the surface.
Runway is calculated as:
Runway = Cash on hand ÷ Monthly burn rate
Burn rate is the pace at which you’re burning through funds – essentially, how much more you’re spending than earning each month (when the latter are lower than the company’s fixed costs). In the pre-seed or seed stage, this often equals your total monthly expenses, since revenue is minimal or nonexistent.
Why is Runway So Important?
1. It’s Your Startup’s Survival Map
Runway tells you how much time you have to hit your next milestone – whether that’s finding product-market fit or raising your next funding round.
In a world full of uncertainty, that’s invaluable insight.
“Startups don’t die because they run out of customers – they die because they run out of cash.”
2. It Enables Quick, Smart Decisions
If you see your runway shrinking faster than expected, you can:
- cut costs,
- optimize marketing spend,
- validate your sales pipeline,
- or start investor talks before the situation becomes critical.
3. It Protects Your Mental Health
Runway also acts as an emotional barometer for founders. Knowing how long you’ve got until you “hit the wall” helps you plan and act proactively – rather than reacting in panic. It gives you clarity and peace of mind.
4. It Builds Your Credibility
Early-stage investors don’t expect profits – but they do expect financial awareness.
If you show that you manage your runway well, you build trust and credibility as a responsible founder.
What’s a Safe Runway?
MINIMUM: 6 months
That’s your critical threshold. In Polish conditions, raising a funding round takes an average of 9 months, so if your runway only covers 6 months, you have minimal time to react. It’s far from a comfortable situation. And if your runway is below 6 months – that’s a red flag.
IDEAL RANGE: 12-18 months
This gives you the room to:
- test and iterate your product,
- scale your sales efforts,
- be selective when choosing investors,
- and absorb delays (especially with grants).
Runway in the Polish context? Be careful with grants, subsidies, and payout timelines!
If your runway includes expected grant payments – be conservative.
Assume at least a 3-month delay buffer compared to the declared payout date.
Formal procedures, internal decisions, and bureaucratic issues often delay payments.
Many startups fail not because they didn’t deserve the money – but because it didn’t arrive on time.
What to Do When Runway Starts Shrinking?
A shrinking runway isn’t the end – but it is a red flag.
Review your sales pipeline – are new revenues realistic?
If not – act fast: cut costs, shift priorities, seek bridge funding.
Consider a bridge round or interim financing.
If your runway is growing – that’s great, but not a reason to get complacent.
Startups are unpredictable – you still need discipline and flexibility.
How Should Founders Use Runway Day-to-Day?
Awareness = safety
Always know your current burn rate and how many months of runway you’ve got left.
Keep it front and center
Literally – put it on your dashboard, track it weekly. Use tools like PowerBI, Google Sheets, Notion, or CFO dashboards.
Act sooner rather than later
It’s better to cut costs two months earlier than to lay off your team two weeks before you run out of cash.
