The Largest European Startups and Private Tech Companies in 2026

Europe produces fewer giant startups than the United States, but its largest private technology companies are now worth tens of billions of dollars and lead global markets in fintech, defense technology, AI and e-commerce. This guide ranks the most valuable European startups in our database by their latest sourced valuation, explains what each group of companies does, and looks at why Europe's startup map has shifted towards AI and defense.

Every valuation in the table links to a full company profile with the source and date. We include companies headquartered in Europe, including the UK, and rank them by their most recent valuation converted roughly to US dollars for ordering. Some valuations are from secondary sales, tender offers or older rounds, which we label on each profile.

The ranking

A few major European companies in our database, such as Starling Bank, OakNorth and Isomorphic Labs, don't have a recent sourced valuation, so they're not ranked. Companies that have gone public, such as Klarna and Wise, aren't included because they're no longer private.

What stands out

Fintech still dominates by value

Fintech has been Europe's strongest startup sector for a decade, helped by open banking rules, a single payments market in the European Union and London's role as a financial centre. Revolut is by far the most valuable European startup at US$75 billion after a 2025 secondary sale, more than many listed banks. Trade Republic in Germany, Checkout.com and Monzo in the UK, Mollie in the Netherlands and Qonto in France show the breadth of the sector across consumer banking, investing, payments and business finance. Several, including N26 and Pleo, still carry valuations set during the 2021 boom, which may not reflect current value.

Defense technology is Europe's new growth story

Russia's war against Ukraine transformed European attitudes to defense spending and defense startups. Governments have committed to much higher budgets, and investors who once avoided weapons-related companies now compete to back them. Helsing, a German AI defense company, has become one of Europe's most valuable startups. Drone makers Quantum Systems in Germany and Tekever in Portugal have also raised at multibillion-dollar valuations. Our guide to defense tech startups covers this trend in depth.

AI has produced Europe's fastest risers

European AI companies have grown at extraordinary speed. Sweden's Lovable, an AI app builder, reached a valuation above US$13 billion within about two years of launch. France's Mistral AI is Europe's leading developer of foundation models. London-based ElevenLabs leads in AI voice, and Wayve is building AI for self-driving cars. AI infrastructure is also growing: Nscale, a British AI cloud company, has raised at a valuation of about US$14.6 billion as it builds data centres across Europe. Germany's Black Forest Labs, Parloa and DeepL, and Sweden's Legora, show the depth of European AI beyond the headline names.

Consumer and commerce

Europe's consumer champions include Vinted, the Lithuanian second-hand fashion marketplace, Back Market, the French refurbished electronics marketplace, Estonia's Bolt in ride-hailing and delivery. Italy's Bending Spoons, which buys and runs well-known apps such as Evernote, WeTransfer and Vimeo, left the private ranks when it listed on Nasdaq in July 2026. London's Nothing is one of the few new smartphone brands to gain traction.

Enterprise software

Germany's Celonis, a process mining company, is one of Europe's most valuable enterprise software startups. Personio in HR software, n8n in workflow automation, Mirakl in marketplace software, Quantexa in decision intelligence and Pennylane in accounting are other examples. Miro, which grew up between Russia, Amsterdam and San Francisco, shows the other side of the story: valued at US$17.5 billion in 2022, it agreed in 2026 to be acquired by Bending Spoons at an enterprise value of US$1.355 billion.

Why Europe has fewer mega-startups than the US

Several structural factors explain the gap. European venture funds are smaller, so late-stage rounds have often depended on US investors. Europe's market is fragmented across languages, regulations and legal systems, which makes it harder to scale quickly than in the single US market. Stock option rules have historically been less generous to employees in some countries, and fewer large tech companies mean fewer experienced executives and less acquisition activity. Many European founders have moved to the US or listed their companies there.

That picture has improved. Pension funds and governments in several countries are encouraging investment in local venture capital, the EU and UK have reformed listing rules, and a new generation of founders, many former employees of successful startups, is building companies with global ambitions from day one. The rise of AI and defense has also created categories where Europe can compete on talent and policy rather than just market size.

How we value European startups

We use the most recent valuation we can confirm from a reliable source, such as a company announcement, regulatory filing or reputable press report. Valuations in euros or pounds are shown in their original currency on each profile, and converted roughly to US dollars only to order this table. Some figures, such as Revolut's and Vinted's, come from secondary share sales rather than new fundraising, and others, such as Checkout.com's, come from internal valuations; each profile explains which type it is. Our guides to post-money valuation and secondaries explain these differences.

How valuations changed after 2021

Many European startups raised at record valuations in 2021, when interest rates were near zero and investors competed for deals. When rates rose in 2022, valuations fell sharply. Some companies, like Checkout.com, cut their internal valuations; others, like Klarna, raised at much lower prices before eventually going public. Companies such as Pleo, N26 and Payhawk haven't published new valuations since the boom. Readers should treat older figures with care and check each profile's date. The companies that have since raised at higher valuations, such as Revolut and Trade Republic, did so by growing revenue and reaching profitability.

Using this list

• Job seekers can identify well-funded European companies and check their growth and funding history.
• Sales teams can find large private companies whose growth creates demand for software and services; see our guide to funding announcements as sales triggers.
• Investors can compare valuations across countries and sectors, and track which companies might list.
• Founders can see which investors back European companies at each stage.

Which European startups might go public next?

Revolut has said it intends to list eventually, and its size makes it one of the most anticipated IPOs in the world. Trade Republic, Monzo, Celonis, Personio, Bolt and Vinted are often mentioned as candidates, along with older companies such as Checkout.com. Defense companies such as Helsing could also consider listings as their revenue grows. Timing depends on market conditions and on where companies choose to list: London, Amsterdam, Frankfurt or New York. Our guide to investing in pre-IPO companies explains how investors gain exposure before listings.

Methodology and limitations

This ranking covers only companies with a published CapFinch profile and a sourced valuation, so it isn't a complete list of every European unicorn. Valuations from different dates aren't directly comparable, and those from 2021 may be well above what investors would pay today. We update profiles as new rounds, secondary sales and listings happen. If you know of a more recent sourced valuation for any company, the profile pages show where our figures come from.
