Few European Deep-Tech Startups Scale Beyond Launch
Doctoral research finds only about 23% of European venture-backed firms grow past the startup stage, versus 54% in the US.
Updated on Nov. 15, 2026 in Startups

Hessel Mittelmeijer published doctoral research at Eindhoven University of Technology on how European deep-tech startups can be commercialised. The work is academic research and has not been tested as a product or program, so it is research-stage. It reports that about 54% of US venture-backed companies grow beyond the startup stage, compared with about 23% in Europe.
Why it matters
Deep-tech startups build technologies in semiconductors, photonics, quantum technology, advanced manufacturing and AI on years of research, yet few European innovations become globally successful companies. The research points to a gap between early-stage industrialisation and the commercialisation stage that investors tend to prefer.
The research compares growth beyond the startup stage among venture-backed companies, with US firms at about 54% and European firms at about 23%. The stub does not give the underlying sample or method behind these shares.
The players
Eindhoven University of Technology
A Dutch technical university whose researchers conducted the doctoral work on commercialising European deep-tech startups.
The details
Deep-tech startups typically face a long, capital-intensive development phase, often called the valley of death, before a product reaches market. The research suggests venture capital investors can navigate that phase by taking a structured approach to value creation across strategy, operations and technology. Investors can also build a network and ecosystem around their fund to offer indirect guidance to startups. Commercial success depends on R&D, strategic partnerships, organisational development, financing and market access.
Timeline
Deep-tech technologies are built over years of research before startup founding.
The Tech Race
The research frames Europe's deep-tech effort against US venture-backed growth, where about 54% of companies move beyond the startup stage versus about 23% in Europe. It positions the commercialisation gap as the bottleneck in a race where European innovation is strong but few firms scale globally.
The findings are research-stage and do not change any product or funding available today. For founders and investors, the work suggests that planning for the long industrialisation phase and for market access may matter as much as the technology itself.
The takeaway
The research points to commercialisation, not invention, as the main constraint on European deep-tech firms reaching global scale. Readers tracking the field can watch for follow-on studies that test whether structured investor support narrows the 54% versus 23% gap.
