How do I know if my business will survive?
A business survives when it can cover its own costs before it runs out of money — and keeps its customers, grows, and earns more from each customer than it costs to win them. Survival is not one number; it is a handful: how long your cash lasts, whether you reach break-even, how many customers stay, and whether the per-customer maths works.
Survival is a few questions, not a feeling
Will you run out of money before you cover your costs? Do customers stick around or leak away? Does each customer earn you more than it cost to get them? Are you growing at a sane pace for your size? If most of those point the right way, you are likely to make it. If several point the wrong way, you have a list of exactly what to fix.
The mistake is judging survival by your bank balance alone. A healthy balance with leaking customers and upside-down economics is a slow death; a small balance heading to break-even is a survivor.
The words behind it
Survival breaks into: runway and break-even (will you run out?), churn and retention (do customers stay?), unit economics — LTV vs CAC (does each customer pay off?), and growth (are you getting bigger?). You do not need the jargon to feel the questions, but each has a healthy range you can check against.
Together these are what we call "viability". A viability score rolls them into one number so you can see at a glance whether you are on track or fragile.

Our free viability score takes a few inputs and grades the pillars that decide survival — survival/runway, unit economics, retention, growth and efficiency — against real benchmarks for your stage, and tells you which ones are dragging you down.
FAQ
What is the single most important sign a startup will survive?
Reaching break-even before you run out of cash (being "default alive"). It is the survival question; everything else — retention, unit economics, growth — either speeds you toward it or drags you away from it.
Can a growing startup still fail?
Yes. Fast growth with bad retention or upside-down unit economics (each customer costs more than they pay) burns cash faster, not slower. Growth only helps survival when the per-customer maths works.
