Why startups fail: the real reasons and how to spot them early

Open a business in Italy and the odds are better than the talk at the bar suggests. Of the businesses born in 2021, 61% were still active three years later, a few points above the EU average. Startups backed by investors play a rougher game. CB Insights studied 431 venture-backed companies that shut down since 2023, and the typical one had raised $11 million before it closed.

This guide looks at why startups fail using the latest data, not folklore. You’ll see the five reasons that keep coming back, the early warning sign for each one and what to do when you spot it. At the end there’s a pre-mortem checklist. It takes an hour with a pen, and it works best before any of the problems are real.

How many new businesses fail in Italy?

Nobody publishes official numbers for startups alone, so we begin with all new businesses. Eurostat follows every enterprise born in a given year and checks how many are still active later on. Here are the most recent figures for Italy, published in October 2026.

Still active in 2024	Italy	EU average
After 1 year (born in 2023)	81.3%	80.5%
After 2 years (born in 2022)	68.5%	67.0%
After 3 years (born in 2021)	61.3%	57.2%

Go further out and the curve keeps sliding. Only 45.8% of the Italian businesses born in 2015 were still active in 2020. So more than half closed inside five years. And remember who is in that count: bakeries, plumbers and the shop on the corner, not just risky tech companies.

The US looks similar. The Bureau of Labor Statistics tracks private-sector establishments by the year they opened. Of those that opened in March 2015, 79.6% made it through year one. By year five, one in two was still open (50.2%), and by year ten about one in three (34.7%).

Venture-backed startups hide inside those figures, mixed in with every other new business. To see why they die, you have to study the shutdowns one at a time.

Why startups fail: what 431 shutdowns tell us

431 startups. That’s how many venture-backed companies CB Insights counted as publicly closed since 2023, in its March 2026 review. For 385 of them it could pin down the reasons, and between them all 431 had raised $17.5 billion in equity.

Reason	Share of shutdowns	Early warning sign	What to do
Ran out of capital	70%	Runway shorter than the time to your next milestone	Cut burn now, raise before you’re desperate, pick milestones the cash can reach
Poor product-market fit	43%	People try it once and don’t come back	Interview the users who left, narrow the customer, stop adding features
Bad timing or macro conditions	29%	Buyers say “great, but not now”	Keep costs flexible, find the segment that needs it today
Unsustainable unit economics	19%	Each new customer costs more than they bring in	Raise prices, cut acquisition cost, drop loss-making customers

Read the top line with care. Seventy percent ran out of money, yet CB Insights itself calls this “the final cause of death, not the root problem.” Paul Graham made the same point in 2007. The official cause of death, he wrote, is always money or a founder walking away, “but I think the underlying cause is usually that they’ve become demoralized.”

The five reasons, with the signs to watch

1. Nobody needs it enough

Poor product-market fit means you built something that a real market doesn’t want badly enough. Two-thirds of these failures in the CB Insights sample were early-stage companies that never found a market at all. Zume is the expensive version: it raised $446 million, pivoted from robot-made pizza to sustainable packaging, and still didn’t find a viable market.

The warning sign is polite enthusiasm. People say they love it, then they don’t pay, don’t come back and don’t tell anyone. Talk to customers before you build and keep talking after; our seven-day plan to validate a startup idea is made for exactly this.

2. The money runs out

Runway is how many months you can last on the cash in the bank: the cash divided by your monthly burn rate, the amount you lose each month. Size doesn’t protect you. Look at Olive and Convoy. Nearly $1 billion raised by each, valuations around $4 billion at the pandemic peak. Then October 2023: both shut down, two weeks apart.

Watch the gap between your runway and your next proof point. CB Insights also noticed that two-thirds of the companies with headcount data were shrinking in their last six months. Do the math every month (our guide to how much money you need to start a startup shows it step by step), cut costs while you still have choices, and start raising well before the last few months of cash. Raising too little is on Graham’s 2006 list of the mistakes that kill startups too: “Too little money means not enough to get airborne.”

3. The team breaks

This one isn’t among the four headline figures, but every founder has seen it. Graham, again in 2006: “Fights between founders are surprisingly common. About 20% of the startups we’ve funded have had a founder leave.”

Early signs: decisions stall, one founder quietly does less, nobody wants to talk about who owns what. Before you incorporate, agree roles, hours and what happens if someone leaves, in writing. Our guide to finding a co-founder lists ten questions to settle first.

4. The timing is wrong

Bad timing or macro conditions sank 29% of the companies. It hit some sectors far harder than others: climate and energy, food and agriculture, blockchain. New Age Meats ($32 million) and RECUR ($55 million) raised at the peak of the alternative-protein and NFT waves, and both closed when the market didn’t follow through.

You’ll hear it before you see it in the numbers: buyers like the idea but say “not now”, and investors in your sector stop answering. Keep your costs flexible, so waiting stays affordable. Then go after the customers who need you today, not the ones who might in five years.

5. The price doesn’t cover the cost

Unit economics is the arithmetic of a single customer: what they bring in against what it costs you to win and keep them. In 19% of the shutdowns those numbers never worked, often among emerging-market fintech companies from the 2021-2022 funding boom, such as ZestMoney ($114 million in equity) and Ula ($141 million), which struggled once capital dried up. The beginner’s version is pricing too low, so that every sale leaves you a little poorer.

If growth gets more expensive every month, stop and measure. Work out what a customer costs to win and what they bring in over time, then fix the price or the channel; our explainer on CAC, LTV and unit economics walks through the formulas.

What keeps a startup alive?

Graham boiled it down to one line: “In a sense there’s just one mistake that kills startups: not making something users want.” Most of the reasons above are that mistake seen from another angle. No market. No money, because there’s no market. A price nobody will pay.

The rest is staying power, and investors know these numbers as well as you do. That’s why they ask about runway, retention and how the founders make decisions, as our piece on what investors look for in a first-time founder explains from their side. Our guide to raising capital for a startup in Italy covers how rounds actually work here. Wondering when it’s safe to go full time? That’s the next step on the beginner’s map from zero to a first round: when to quit your job for a startup. Keep our startup glossary open in another tab if any term is new.

Run a pre-mortem: your checklist

Gary Klein described the premortem in Harvard Business Review in September 2007. The team assumes the project has just failed and then lists plausible reasons why. Try it on your own startup this week.

1. Write the headline “[Your startup] shut down in 2028” and give yourself fifteen minutes to list every reason it could have happened.
2. Sort the reasons into the five groups: need, money, team, timing, unit economics.
3. For each group, jot down the first warning sign you’d notice, then pick a date to go and look for it.
4. Work out your runway in months. Then name the one milestone that cash can actually get you to.
5. Get your co-founders to sign off on roles and ownership, in writing. Then add the awkward bit: what happens if somebody leaves.
6. Set a pivot rule now: if a specific result hasn’t happened by a specific date, you change course.
