The AI Migration: Europe’s Hottest Startups Head to the US by Default

The recent trend of European AI startups flocking to the United States in pursuit of venture capital and enterprise demand has sparked a discussion on the future of innovation and entrepreneurship. Carl Fritjofsson, an investor with Creandum, notes that the timeline for European founders to cross the Atlantic is compressing at an unprecedented pace.

The statistics are striking: AI firms have captured 61% of global venture capital in 2025, with American enterprise procurement budgets driving much of this demand. In the first quarter of 2026, these firms accounted for 80-81% of all venture capital investments. Fritjofsson’s portfolio company, Lovable, has achieved remarkable growth without a traditional expansion strategy, adding $100 million in revenue in one month and reaching a valuation of $6.6 billion.

However, not all European startups can replicate Lovable’s success. For those focused on enterprise solutions, the process of expanding to the US is complex and costly. The Trump administration’s visa policies have created additional hurdles for founders seeking to bring their teams across the border. A $100,000 fee has been imposed on new H-1B applications, a 6,500% increase from previous rates.

Fritjofsson remains optimistic about the prospects of AI startups in the US, attributing the shift in demand to the deregulatory environment and its benefits outweighing immigration challenges. Data suggests that European venture funding has grown modestly while US companies have captured a significant share of global venture capital.

The trend is not solely driven by regulatory changes or visa policies; a deeper structural challenge exists within Europe’s AI ecosystem. A 2024 report found that European countries are losing significant AI talent to the US, despite having roughly 30% more AI professionals per capita than their American counterparts. Many lead investors in European AI companies are also American, indicating where capital conviction lies.

Klarna’s experience rebuilding a product for the American market before achieving growth is an example of the old playbook. Lovable’s success represents the new paradigm – one that doesn’t require a traditional expansion strategy.

As European founders navigate these developments, they should be asking themselves not when to go to the US but whether AI has made this question obsolete. The trend suggests that American markets are increasingly attractive for AI startups and Europe’s structural challenges run deeper than visa policies.

The implications of this trend are far-reaching. As more European startups migrate to the US, will they replicate Lovable’s success or succumb to pressures of rebuilding their products for an unfamiliar market? What does this mean for innovation in Europe and can its AI ecosystem recover from this brain drain?

To address these questions, European governments and investors should focus on creating a more conducive environment for homegrown startups to thrive. This includes addressing structural challenges such as retaining talent and providing adequate funding. Rather than trying to compete with the US on its own terms, Europe should reevaluate its approach to AI development.

Ultimately, the migration of European AI startups to the US is a symptom of a larger issue – one that requires a nuanced understanding of its complexities.
