Over the last decade, the global startup ecosystem experienced unprecedented growth followed by equally dramatic collapses. Easy capital, low interest rates, aggressive valuations, and founder-centric narratives created some of the most valuable private companies in history. However, many of these high-profile startups failed to convert scale into sustainable business models. When economic conditions tightened, structural weaknesses surfaced rapidly.
From crypto exchanges and fintech lenders to coworking giants and media startups, several once-celebrated companies collapsed under debt, mismanagement, and flawed assumptions. These bankruptcies reshaped investor behavior, regulatory frameworks, and founder accountability across industries.
This article explores the biggest startup bankruptcies of the past decade, explains why they failed, and outlines where each case stands today.
FTX: The Largest Startup Collapse in Modern History
FTX represented the peak of crypto-era ambition and the depth of its excess. Founded in 2019, the crypto exchange grew at breakneck speed and achieved a valuation exceeding $30 billion within three years. Investors, regulators, and customers trusted the platform as a sophisticated and compliant marketplace.
FTX collapsed in November 2022 after customers rushed to withdraw funds. Internal records revealed that the company transferred billions of dollars of customer assets to a related trading firm. Leadership concealed losses, ignored basic accounting practices, and failed to separate customer funds from proprietary trading capital.
The bankruptcy exposed one of the largest financial holes ever recorded in a startup failure. Courts uncovered missing or misused assets worth billions of dollars. Prosecutors pursued criminal cases against senior executives, while regulators intensified scrutiny of the crypto industry.
By 2024, the FTX bankruptcy estate recovered a significant portion of lost assets through liquidations, clawbacks, and settlements. Courts approved a structured repayment plan that allowed many customers and creditors to receive substantial recoveries. The case set a landmark precedent for how courts handle digital assets during insolvency.
FTX fundamentally changed how investors evaluate governance risk in crypto startups and forced regulators worldwide to accelerate compliance frameworks.
WeWork: From Visionary Disruptor to Debt-Laden Reality
WeWork symbolized the excesses of venture-backed growth culture. The coworking company expanded globally by signing long-term real estate leases while offering short-term memberships to customers. This mismatch created enormous fixed obligations and thin margins.
At its peak, private markets valued WeWork at nearly $47 billion. Leadership promoted the company as a technology platform rather than a real estate operator. Investors accepted those claims until financial disclosures revealed massive losses and questionable governance practices.
The COVID-19 pandemic devastated office demand and exposed WeWork’s fragile model. Revenue declined sharply while lease obligations remained fixed. By November 2023, the company filed for Chapter 11 bankruptcy protection.
During 2024, WeWork renegotiated or exited hundreds of leases, eliminated billions in debt, and reduced its global footprint. Creditors took control of the reorganized company, while existing shareholders lost nearly all value. WeWork exited bankruptcy as a smaller, more conservative operator.
The WeWork collapse forced investors to re-evaluate asset-heavy business models and reinforced the importance of unit economics over branding narratives.
Celsius Network: Yield Promises Meet Market Reality
Celsius Network attracted millions of users by promising high yields on crypto deposits. The company marketed itself as a safer alternative to banks while deploying customer assets into risky and illiquid strategies.
When crypto prices fell sharply in 2022, Celsius faced mounting losses and liquidity constraints. The company halted withdrawals and filed for bankruptcy shortly afterward. Internal documents showed that Celsius lacked adequate risk controls and overstated the value of its assets.
The bankruptcy process revealed billions of dollars in customer claims and a significant shortfall between assets and liabilities. Courts ruled that customer deposits constituted unsecured loans rather than custodial assets, a decision that shocked many users.
By 2024, Celsius advanced through restructuring efforts that included asset liquidations and partial creditor repayments. The case reshaped how crypto lenders disclose risks and clarified legal ownership of deposited digital assets.
Celsius highlighted the dangers of unsustainable yield models in volatile markets.
BlockFi, Voyager, and the Crypto Contagion Effect
The collapse of major crypto lenders triggered a chain reaction across the digital asset ecosystem. BlockFi and Voyager Digital expanded rapidly by offering yield-bearing accounts and loans backed by volatile collateral. Both companies maintained exposure to high-risk counterparties.
When crypto hedge funds collapsed and market liquidity evaporated, these platforms lost access to capital and faced mass withdrawal requests. Both companies filed for Chapter 11 bankruptcy in 2022.
The bankruptcy courts oversaw asset sales, recovery actions, and creditor distributions throughout 2023 and 2024. BlockFi confirmed a repayment plan and began distributing recovered funds to customers. Voyager pursued settlements and asset liquidations to maximize creditor returns.
These failures demonstrated how interconnected financial exposure magnifies systemic risk in unregulated markets. The events accelerated regulatory action and investor caution in crypto lending.
Three Arrows Capital: Leverage Without Limits
Three Arrows Capital operated as one of the most influential crypto hedge funds in the world. The firm employed extreme leverage and concentrated bets on speculative digital assets. Rising markets masked these risks until prices reversed sharply.
When crypto prices collapsed in 2022, Three Arrows defaulted on massive loans and entered liquidation. Creditors across multiple jurisdictions pursued recovery actions. The case exposed the dangers of unchecked leverage and opaque fund structures.
Liquidators continued to pursue asset recovery and litigation through 2024. The collapse reinforced the importance of transparency and risk limits in hedge fund operations.
Quibi: A Billion-Dollar Media Experiment That Failed Fast
Quibi launched in 2020 with a bold vision: premium short-form video designed exclusively for mobile users. Backed by nearly $2 billion in funding and high-profile leadership, the company expected rapid subscriber growth.
The platform failed to gain traction. Consumers rejected the pricing model and content format. The pandemic shifted viewing habits toward long-form and home-based entertainment, undermining Quibi’s core assumptions.
The company shut down within six months. Instead of filing a prolonged bankruptcy, Quibi sold its content library and intellectual property at a steep discount.
Quibi became a textbook example of how funding and brand power cannot substitute for product-market fit.
Theranos: Innovation Claims Without Scientific Proof
Theranos promised to revolutionize blood testing through proprietary technology. The company raised hundreds of millions of dollars and secured partnerships with major institutions. Leadership restricted transparency and discouraged technical scrutiny.
Investigations revealed that the technology never worked as claimed. Regulators intervened, partnerships collapsed, and the company dissolved in 2018.
Criminal convictions of senior leadership followed years later, reinforcing accountability standards in healthcare innovation. The Theranos case permanently changed how investors approach diligence in biotech startups.
Key Lessons from a Decade of Startup Bankruptcies
These failures reveal consistent patterns:
• Founders prioritized growth narratives over operational discipline
• Companies ignored liquidity risk and balance sheet mismatches
• Boards failed to enforce accountability
• Investors underestimated downside risk during boom cycles
• Regulatory gaps allowed systemic vulnerabilities to grow
Bankruptcy courts increasingly act as de facto regulators, particularly in emerging industries like crypto.
Conclusion: The End of Growth at Any Cost
The last decade of startup bankruptcies closed an era defined by unchecked optimism and cheap capital. These collapses reshaped venture funding, governance expectations, and regulatory oversight worldwide.
Today’s investors demand transparency, sustainable margins, and disciplined leadership. Founders face higher accountability standards, and regulators intervene earlier in high-risk sectors.
The lessons from these failures continue to shape the next generation of startups. Innovation still thrives—but markets now demand proof, not promises.
