Our review

«The Startup Bubble» arrives as an antidote to the triumphalist narrative that dominates startup culture. Its authors — economists, researchers, and battle-scarred entrepreneurs — argue that the startup ecosystem of the past two decades has been artificially inflated by cheap money, image culture, and a narrative that conflates risk with vocation. The book dismantles operational myths: most unicorns lose money for years before becoming profitable (or never do), the real failure rate of startups vastly exceeds 90% when silent dissolutions are included, and the venture capital financing model is structurally designed to favour investors over founders. The work is more diagnostic than prescriptive: it identifies the perverse incentives of the system with precision without always offering alternatives as detailed as the analysis itself. Its primary value is therapeutic and analytical — it restores scepticism to a debate that had lost it. A fair critique: as a collective work, the consistency of voice and the depth of arguments varies between chapters, and some analyses remain at the surface of phenomena that deserve deeper treatment.

Key takeaways

• The entrepreneurship-as-individual-heroism narrative ignores the structural factors — networks, starting capital, ecosystem access — that actually determine success.
• Many unicorn valuations reflect optimism about future profits, not present profitability; the distinction is critical for any serious analysis.
• Venture capital has incentives to maximise exit value, not the long-term health of the business or the well-being of the founder.
• Business failure is a predictable statistical event, not a moral anomaly; normalising it is a precondition for learning from it.

Fact

According to OECD data and various academic studies, between 60% and 90% of startups do not survive five years, depending on the sector and measurement methodology used.
