How CERN alumni turn science into startup

CERN Venture Connect has conducted an impact study that highlights how CERN alumni founders translate scientific excellence into real-world innovation, creating companies that address global challenges in health, energy, climate, or even advanced engineering.

The study examined a sample of 20 startups founded or co-founded by CERN alumni, capturing entrepreneurial impact that occurred before formal engagement with CERN Venture Connect. The aim is to better understand how CERN technologies and know-how contribute to the creation of startups, growth, and market activity over time for ex-CERN employees.

The startups operate across high-impact sectors, including health and biotechnology, clean energy and climate technologies, advanced engineering, radiation protection, nuclear technologies, and digital and data-driven solutions. This diversity highlights CERN’s influence beyond particle physics, as alumni translate complex scientific expertise into market-facing technologies and viable businesses.

Company maturity, scale, and markets

The sample spans the full company lifecycle. Approximately one quarter of the companies are early-stage (pre-seed or seed), around half are in scaling phases (Series A or B), and the remaining quarter are more mature businesses (Series B+ or established).

Company size ranges from single-founder ventures to organisations employing more than 200 full-time equivalents (FTEs). Based on reported figures, the combined workforce across the sample is estimated at 700–800 employees.

Most surveyed startups operate beyond their home country.

Over 70%

report international operations
including activity across Europe, North America, and other regions

The majority focus on B2B markets, serving hospitals, industrial companies, public-sector organisations, and research institutions. This indicates that CERN alumni entrepreneurship is largely oriented towards international, technology-intensive markets.

In terms of commercial maturity,

75%

of companies have progressed beyond the seed stage, and

60%

report having launched a commercial product or service.

5

companies self-report annual revenues

exceeding €1 million

while several others remain pre-revenue or at early market-entry stages.

Role of CERN technology and know-how

More than 70%

of surveyed startups report using CERN-developed technology or know-how
such as detector technologies, vacuum systems, data infrastructures, software,
engineering methods, and scientific approaches.

The contribution of CERN inputs varies across companies. In some cases, CERN technology is embedded directly in the product; in others, it supports product design, manufacturing, testing, validation, or R&D processes. Among startups using CERN technology or know-how:

Approximately

25%

attest that it contributes

more than 50%

of their business value.

These figures reflect that CERN acts as an enabler, reducing technical risk and accelerating development, even when not directly visible in turnover.

Beyond measurable impact

More than 50%

of companies claim actively promoting their CERN connection,
citing scientific credibility, technical excellence, and trust as important factors
when engaging investors, partners, and customers.

As one founder explains, “CERN is a well-recognised name in the field of nuclear sciences”. Another respondent highlights how this association helps position young companies in competitive markets: “It situates my unknown company as one with a renowned background”. Beyond market credibility, several founders point to the role of the CERN brand in building teams. One alumnus notes that the connection helps with “finding talent” and “talent attraction”. Several respondents also emphasised that skills acquired at CERN, such as interdisciplinary collaboration, problem-solving in complex environments, and working in international teams, provide value that is difficult to quantify but materially significant.

Collectively, the startups contribute to multiple UN Sustainable Development Goals, most notably SDG 3 (Good Health and Well-being), SDG 7 (Affordable and Clean Energy,) and SDG 9 (Industry, Innovation and Infrastructure).

Through its people, culture, technologies, and know-how, CERN enables alumni founders to build internationally active, science-based companies with measurable economic and societal relevance, often before structured programme support begins.
