The Czech Republic punches far above its weight in European technology. A country of just under 11 million people has produced the world’s most widely used developer tools company, one of the biggest names in consumer cybersecurity, and a growing herd of unicorns spanning e-grocery, hospitality software, and enterprise data management. Prague’s tech ecosystem alone is now worth roughly €19 billion in enterprise value — a figure that has grown about eightfold since 2019, according to Dealroom data.
But ranking Czech tech companies “by market cap” comes with an important caveat that most listicles skip: the majority of the country’s most valuable technology firms are privately held. The Prague Stock Exchange (PSE) is dominated by energy and banking giants like ČEZ, and very few pure-play tech firms trade publicly. So in this guide, we rank companies by market capitalization where they are (or were) publicly traded, and by their latest reported private valuation where they are not — and we tell you which is which. That transparency matters if you’re an investor, job seeker, or founder using this list to make real decisions.
Let’s dive into the top 10 biggest tech companies in the Czech Republic in 2026.
How We Ranked These Companies (Methodology)
To keep this list credible and useful, we applied three rules:
First, a company qualifies as “Czech” if it was founded in the Czech Republic or maintains its headquarters and core operations there — even if it later incorporated abroad or was acquired by a foreign parent, which is common for scale-ups in Central and Eastern Europe. Second, we use market capitalization for listed companies and the most recent credible valuation (funding round, acquisition price, or secondary-market estimate) for private ones. Third, all figures are approximate and change constantly; treat them as directional, not gospel. This article is for informational purposes only and is not investment advice.
- JetBrains — ~$7+ Billion (Private)
If you’ve ever met a professional software developer, there’s a very good chance they use a JetBrains product every single day. Founded in Prague in 2000, JetBrains builds the industry-standard suite of integrated development environments (IDEs) — IntelliJ IDEA, PyCharm, WebStorm, and more — and created Kotlin, the programming language Google endorsed as its preferred language for Android development.
What makes JetBrains remarkable is that it grew organically, without external venture funding, into a global company with well over 1,800 employees across a dozen offices. Because it has never gone public, its exact value is debated, but secondary-market reports and analyst estimates have consistently placed it among the most valuable privately held companies to come out of Central and Eastern Europe — alongside names like Bolt and ElevenLabs. By most credible estimates, JetBrains is the single most valuable tech company of Czech origin today.
Why it matters: JetBrains proves a bootstrapped Czech company can dominate a global developer market against Silicon Valley competition.
- Avast / Gen Digital — ~$8.6 Billion Exit (Formerly Listed)
Avast is the Czech Republic’s most famous tech success story. Founded in Prague in 1988 — before the Velvet Revolution — Avast grew into one of the world’s largest consumer cybersecurity companies, protecting hundreds of millions of devices with its freemium antivirus model. It listed on the London Stock Exchange in 2018 in one of the exchange’s biggest-ever tech IPOs.
In 2022, Avast merged with NortonLifeLock in a deal that valued the Czech firm at roughly $8.6 billion, creating the combined entity now known as Gen Digital. While Avast is no longer independently listed, Prague remains a major engineering and operations hub for Gen Digital, and Avast’s founders and early employees have become prolific angel investors seeding the next generation of Czech startups. On pure historical market value, Avast remains the benchmark every Czech tech company measures itself against.
Why it matters: Avast delivered the largest tech exit in Czech history and recycled capital and talent back into the local ecosystem.
- Seznam.cz — Estimated $2–4 Billion (Private)
Seznam.cz is one of the very few companies in the world that has managed to hold its ground against Google on home turf. Founded in 1996 by Ivo Lukačovič, Seznam operates the Czech Republic’s leading homegrown search engine, email service, maps, news portal, and a sprawling network of online media and advertising properties.
Seznam has never sold and never listed, so public valuation figures are estimates — but given its dominant share of the Czech digital advertising market, consistent profitability, and diversified media portfolio, analysts typically place its worth in the low billions of dollars. For a single-market internet company, that is an extraordinary outcome, and it makes Seznam arguably the most strategically important digital company in the country.
Why it matters: Seznam is a rare example of a national champion resisting Big Tech dominance in search and online media.
- Rohlik Group — ~$1.7 Billion (Private, Unicorn)
Founded in Prague in 2014 by serial entrepreneur Tomáš Čupr, Rohlik reinvented online grocery for Central Europe. Rather than racing for 10-minute delivery, Rohlik bet on breadth — more than 17,000 products including fresh local food — combined with reliable 60–90 minute delivery windows. The formula worked: Rohlik became the Czech Republic’s first unicorn in 2021 and has raised over $760 million, one of the largest funding totals of any company born in Central and Eastern Europe.
Today Rohlik operates in the Czech Republic, Hungary, Austria, Germany, and Romania under brands like Knuspr and Kifli, with an ambitious plan to reach dozens of European cities by 2030. Backers include Index Ventures, Partech, and Sofina.
Why it matters: Rohlik broke the unicorn barrier for Czechia and exports a genuinely differentiated e-grocery model across Europe.
- Productboard — ~$1.7 Billion (Private, Unicorn)
Productboard, founded in 2014 by Hubert Palan and Daniel Hejl, builds product management software that helps teams decide what to build next by consolidating customer feedback, prioritizing features, and aligning roadmaps. It reached unicorn status in early 2022 after a $125 million Series D that valued the company at approximately $1.7 billion, with investors including Index Ventures, Tiger Global, and Czech fund Credo Ventures.
With dual roots in Prague and San Francisco, Productboard serves thousands of customers, including major enterprises like Microsoft, Zoom, and Volkswagen. It has become the flagship example of a Czech-founded B2B SaaS company selling successfully to the global enterprise market.
Why it matters: Productboard showed that Czech founders can build category-defining enterprise SaaS for the world, not just the region.
- Mews — ~$1.2+ Billion (Private, Unicorn)
Mews was born from firsthand frustration: founder Richard Valtr was running a Prague hotel in 2012 and couldn’t find modern software to manage it, so he built his own. Today Mews is a leading cloud-based property management system (PMS) for hotels, handling reservations, check-ins, guest communication, and payments for thousands of properties across more than 80 countries.
Mews officially became a Czech unicorn after an investment round that pushed its valuation past $1.2 billion, backed by investors including Kinnevik, Goldman Sachs, Notion Capital, and Tiger Global. The company has grown aggressively through acquisitions of competing hospitality software firms and continues to expand its embedded payments business, one of its fastest-growing revenue streams.
Why it matters: Mews is digitizing a massive, traditionally underserved industry — and doing it from Prague.
- Ataccama — ~$1 Billion (Private, Unicorn)
Ataccama is the quiet giant of Czech enterprise software. The company provides a unified data management and governance platform — covering data quality, master data management, and data cataloging — that large enterprises use to keep their data trustworthy enough for analytics and AI. In 2022, Bain Capital Tech Opportunities invested $150 million into Ataccama, cementing its place among the country’s five recognized unicorns alongside JetBrains, Rohlik, Productboard, and Mews.
As enterprise AI adoption accelerates, demand for exactly what Ataccama sells — clean, governed, AI-ready data — has surged, positioning the company well for the next several years.
Why it matters: Ataccama sits directly in the path of the enterprise AI boom, where data quality is the bottleneck.
- Kiwi.com — ~$1 Billion+ at Peak (Private)
Founded in Brno in 2012 by Oliver Dlouhý, Kiwi.com pioneered “virtual interlining” — an algorithmic approach that combines flights from airlines that don’t cooperate with each other into single bookable itineraries, often at dramatically lower prices. At its peak, Kiwi.com was one of Europe’s fastest-growing travel tech companies, and General Atlantic’s majority investment in 2019 reportedly valued the business at around a billion euros.
The pandemic hit travel tech hard, but Kiwi.com survived, restructured, and rebounded with the recovery of global travel. It remains Brno’s flagship tech company and one of the largest online travel players founded in Central Europe.
Why it matters: Kiwi.com proved world-class travel technology can be built outside Prague — and outside Western Europe entirely.
- Livesport — Estimated High Hundreds of Millions to ~$1 Billion (Private)
Livesport, the Prague-based company behind Flashscore and a family of live sports data brands, is one of the most profitable and least talked-about companies in Czech tech. Its real-time sports scores and statistics platforms attract over 100 million users worldwide, monetized through advertising and partnerships at enviable margins.
Because Livesport is founder-owned and has never needed to raise venture capital, it publishes no valuation — but based on its reported revenues and profitability, it would comfortably rank among the most valuable Czech digital companies if it ever came to market.
Why it matters: Livesport is a masterclass in building a quietly dominant global consumer product from Prague without outside capital.
- Bohemia Interactive — Estimated Hundreds of Millions (Private)
No list of Czech tech would be complete without gaming, and Bohemia Interactive is the sector’s anchor. Founded in Prague in 1999, the studio created the Arma military simulation franchise and DayZ, the survival game that helped launch an entire genre. Its titles have sold tens of millions of copies, and its simulation technology is even used in professional military training.
The Czech gaming cluster around Bohemia — including Warhorse Studios (Kingdom Come: Deliverance) and SCS Software (Euro Truck Simulator) — collectively generates hundreds of millions in revenue and gives the country an outsized reputation in global game development.
Why it matters: Gaming is one of Czechia’s strongest tech exports, and Bohemia Interactive built the foundation.
Honorable Mentions
Several companies narrowly missed the top 10 but deserve attention: GoodData (analytics, backed by major US VCs), Y Soft (enterprise print management), SCS Software and Warhorse Studios (gaming), Pilulka (e-pharmacy, one of the few tech-adjacent names actually listed on the Prague Stock Exchange), and fast-rising AI startups emerging from Prague’s 300+ VC-backed startup pool.
Key Takeaways for 2026
Three trends define Czech tech right now. The ecosystem is maturing — five recognized unicorns and €2.5 billion raised since 2019 make Czechia a late-stage funding leader in CEE. Capital is recycling — Avast’s exit created a generation of angel investors funding new startups. And the public markets remain untapped — with almost no Czech tech firms listed locally, the first major Prague tech IPO could be a landmark moment for the region.
