20 failed startups
and the mistake behind each

Startups usually fail because they run out of money before finding a product people want at a price that covers its costs. Behind that are recurring mistakes: building without real demand (Quibi), over-engineering (Juicero), scaling before unit economics work (Webvan, PepperTap), buying growth with discounts (Homejoy), ignoring the people who create value (Vine), and misreporting or governance failures (GoMechanic). Most deaths have several causes, but one usually decides it.

Quick answer: Why do most startups fail?

  1. No real demand — the most common root cause.
  2. Scaling before unit economics — every order loses money, faster.
  3. Over-building — solving a problem nobody had with expensive tech.
  4. Buying growth — discounts that attract customers who don't stay.
  5. Trust failures — misreporting and governance problems end companies overnight.

Key takeaways

  • Money runs out because of an earlier mistake — usually missing demand or broken unit economics.
  • Funding magnifies mistakes: big rounds let flawed models scale further before they break.
  • Retention, not sign-ups, tells you whether demand is real.
  • Dependence on one partner, platform or financier is a hidden single point of failure.
  • Honest reporting is non-negotiable; once trust breaks, recovery is rare.

Startups rarely die of one thing. But read enough post-mortems and a pattern appears: there is usually one decision, made early, that turned a hard problem into a fatal one. Money runs out last; the mistake came first. CB Insights' long-running analysis of startup post-mortems finds the same top causes again and again — no market need, running out of cash, being outcompeted, and flawed business models1.

Here are twenty companies — global and Indian, famous and forgotten — and the mistake that, more than any other, decided their fate. Every story is simplified; each had several causes.

At a glance: Why do most startups fail?

Mistake 1: building something people didn't want enough

1. Quibi — the wrong product for how people watch

Quibi raised about $1.75 billion for premium "quick bites" of video designed for phones on the go — then launched in April 2020, when nobody was going anywhere. It shut down roughly six months later. Its founders' letter said the idea may not have been strong enough to justify a standalone streaming service, or the timing was wrong2. Lesson: big budgets can't substitute for evidence that people want the format.

2. Juicero — over-engineering a problem nobody had

A $400 Wi-Fi-connected juice press that squeezed proprietary produce packs. In 2017, Bloomberg reporters showed the packs could be squeezed by hand with about the same result. Juicero shut down that September3. Lesson: complexity is not value. Ask what the simplest solution would be — and whether customers would accept it.

3. Color Labs — launching with money, not a reason to use it

Color raised $41 million before launch in 2011 for a photo-sharing app built around proximity. Early users found it confusing and empty, and the company wound down the following year. Lesson: funding doesn't create a reason to use a social product; early users must get value on day one.

4. Google+ — no reason to switch

Google's social network had enormous distribution but never gave people a compelling reason to move their friends and habits from Facebook. Google shut the consumer version in 2019 after disclosing a data-exposure bug. Lesson: in network products, "better features" rarely beat "my friends are already there".

Mistake 2: scaling before the unit economics worked

5. Webvan — building the warehouse before the demand

The dot-com grocery delivery company spent heavily on automated warehouses across several US cities before proving that enough customers would order profitably. It went bankrupt in 2001. Lesson: prove the economics in one city before building infrastructure for twenty.

6. Pets.com — selling heavy goods at a loss

Shipping bulky pet food cheaply meant many orders lost money. A famous brand couldn't fix a model where growth made losses bigger; the company liquidated in 2000, months after its IPO. Lesson: if each order loses money, more orders is not a strategy.

7. PepperTap — discounts and too many stores, too fast

The Gurgaon grocery-delivery startup shut down its delivery operations in April 2016, about 17 months after launch. It cited weak integration with partner stores, reliance on deep discounts and a high cash burn7. Lesson: discounts hide whether customers value the service; integration problems multiply with every city.

8. TinyOwl — expanding cities faster than learning

The food-ordering app expanded rapidly across Indian cities in 2015, then cut staff and closed locations as funding tightened, later merging with logistics company Roadrunnr. Lesson: each new city multiplies costs before it multiplies learning. Win one first.

9. Fast — hiring for a business that didn't exist yet

The one-click checkout startup raised over $120 million and hired hundreds of people, but reportedly generated only about $600,000 in revenue in 2021. It shut down in April 20225. Lesson: headcount should follow traction, not funding.

Mistake 3: buying growth that didn't stay

10. Homejoy — customers acquired, not retained

The on-demand cleaning startup grew quickly with heavy promotions, struggled to keep customers coming back, and faced lawsuits over classifying cleaners as contractors. It shut in July 2015; its CEO called the classification issue the deciding factor in failing to raise more money4. Lesson: promotional growth without retention is rented, not owned — and regulatory risk can arrive at the worst moment.

11. Stayzilla — a model that never stabilised

The homestay marketplace raised about $34 million but halted operations in February 2017, saying it would reboot with a different model8. Lesson: without a sustainable core model, each pivot costs more money and trust.

12. Dunzo — burning cash in a race that never ended

Once a beloved delivery app, Dunzo moved into fast grocery delivery against heavily funded competitors, cut operations repeatedly as funding dried up, and went offline in January 20259. Lesson: don't enter a capital-intensive race unless you can outlast the best-funded rival — or change the race.

Mistake 4: ignoring the people who created the value

13. Vine — never paying its creators

Vine's six-second videos built huge audiences, but Twitter never built ways for creators to earn. Many moved to platforms that paid them; Twitter announced Vine's shutdown in October 2016. Lesson: in a creator platform, the creators are your supply. If they can't earn, they leave.

14. Friendster — too slow to load

An early social network with explosive growth, Friendster struggled with slow page loads as it scaled. Users drifted to faster rivals like MySpace and later Facebook. Lesson: performance is a feature; frustrated users don't wait.

Mistake 5: losing on product and focus

15. Jawbone — quality problems in a crowded market

The maker of speakers and fitness trackers raised hundreds of millions but faced product reliability complaints and fierce competition from Fitbit and Apple. It went into liquidation in 2017. Lesson: in hardware, quality problems compound — returns, reviews and cash all suffer at once.

16. Convoy — no buffer for a downturn

The digital freight startup raised money at a $3.8 billion valuation, then shut down in October 2023 when a freight recession met tight capital markets and no buyer emerged6. Lesson: cyclical industries need cash buffers and costs that flex with demand.

Mistake 6: dependence and governance

17. BluSmart — a single point of financial failure

The electric ride-hailing service suspended bookings in April 2025 after SEBI's interim order against the promoters of Gensol Engineering, which financed and leased much of its fleet, over alleged misuse of EV loan funds11. Lesson: dependence on one related financier or partner is a risk to the whole business — however good the product.

18. Byju's — growth on credit

Once India's most valuable startup, the edtech company expanded through large acquisitions and debt, then faced disputes with lenders and investors. In July 2024 the NCLT admitted an insolvency petition over unpaid sponsorship dues to the BCCI12. Lesson: debt-funded expansion leaves no room for a slowdown.

19. GoMechanic — misreporting the numbers

The car-servicing startup's co-founder admitted in January 2023 to "grave errors" in financial reporting under a "growth at all costs" mindset; a funding round collapsed and most staff were laid off10. Lesson: inflated numbers buy time, then destroy everything. Report honestly, especially when growth is slow.

20. Theranos — promising what the technology couldn't do

The blood-testing company claimed its devices could run many tests from a finger-prick of blood. They couldn't, and its founder was convicted of fraud in 2022. Lesson: in health and science, claims must follow evidence. There is no "fake it till you make it".

How to avoid becoming a case study

Checklist: How to avoid becoming a case study — Validate demand; Measure retention; Know your unit economics; Keep burn proportional; Avoid single points of failure; Report honestly.
How to avoid becoming a case study
  • Validate demand before you build — see how to validate an app idea
  • Measure retention before acquisition — a retention and churn audit shows whether demand is real
  • Know your unit economics per order, customer and city before expanding
  • Keep burn proportional to evidence, not to the size of the last round
  • Avoid single points of failure — one partner, one financier, one platform
  • Report honestly to your board, investors and team, especially when it's bad news

Key terms, defined

Unit economics — revenue and costs per unit, such as an order or a customer. Burn rate — how fast a company spends cash. Retention — the share of customers who keep using a product. Runway — how long a company can operate before cash runs out. Post-mortem — an analysis of why a project or company failed.

Frequently asked questions

What is the number one reason startups fail?

Running out of cash is the immediate cause, but the root cause is usually a lack of market need — building something people don't want enough to pay for at a sustainable price. CB Insights' analyses of startup post-mortems consistently rank these among the top reasons.

What percentage of startups fail?

Estimates vary by definition and country, but most studies find that a large majority of venture-backed startups do not return their investors' money, and many small businesses close within their first several years. Treat precise percentages with caution.

Why did Quibi fail?

Quibi raised about $1.75 billion and shut down roughly six months after its April 2020 launch. Its founders said the idea may not have been strong enough for a standalone streaming service, or the timing was wrong. It had far fewer subscribers than projected.

Why do Indian startups fail?

Common patterns include scaling with deep discounts before unit economics work, expanding to many cities too fast, dependence on continuous fundraising, and in some cases governance and reporting failures. Quick-commerce, food and grocery delivery have seen several high-profile shutdowns.

How can I avoid startup failure?

Validate demand before building, measure retention and unit economics before scaling, keep burn low until the model works, avoid dependence on a single partner or funder, report honestly, and talk to customers continuously.

Is failure common among funded startups?

Yes. Funding gives a startup more time and resources, but it doesn't create demand. Several of the most expensive failures — Quibi, Webvan, Fast — were extremely well funded.
