The Deloitte Technology Fast 50 Central Europe 2025 Report paints a picture of a region undergoing rapid transformation, where despite macroeconomic uncertainties, technology companies continue to demonstrate unparalleled resilience and growth. Similar to previous years described as a “tale of two halves,” 2025 showcases a dynamic landscape in which innovation thrives even under economic pressure. Average four-year revenue growth among the 50 fastest-growing companies surpassed 1,200%, a remarkable achievement given the challenging operating environment. As the report notes, these companies are not only scaling quickly—they are shaping customer expectations and influencing industry standards across global markets.
One of the defining characteristics of the 2025 cohort is the strength of proprietary technology. To qualify for the Fast 50 ranking, companies must derive the majority of their revenue from their own IP—a requirement that reveals how well they understand the market and how effectively they are responding to emerging customer needs. Deloitte’s Programme Leader highlights that these are not simply “great technology businesses, but great businesses full stop”—enterprises capable of anticipating demand before the market recognises it.
The 2025 ranking is led by Czech-based Oddin.gg, which secured first place for the second year in a row. With a staggering 4,267% revenue growth, the company continues its mission to elevate esports engagement and provide sportsbook operators with advanced, risk-reducing solutions. Its expansion into Latin America, coupled with its commitment to integrity and responsibility, solidifies its positioning as a global leader in esports infrastructure. In second place, Slovakia’s PowereX posted an impressive 2,510% growth, leveraging AI-driven systems to optimise energy flexibility and accelerate the decarbonisation of Europe’s energy infrastructure. Polish SaaS company Mizzox, growing 2,504%, completes the top three with its AI-powered accounting automation tools designed for the era of mandatory e-invoicing. These top performers highlight not only technological sophistication but also the increasing maturity of Central Europe’s tech ecosystem.
Across the full ranking, software continues to dominate with 31 entrants, followed by fintech and media/entertainment. The industry distribution underscores a broader trend: the convergence of AI, automation, and data-driven decision-making in nearly every vertical. Companies such as FaceUp Technology, Surveily, and Antigro Designer demonstrate how AI and machine learning are no longer optional upgrades but essential engines driving competitive advantage and operational efficiency. The geographic distribution is equally telling, with the Czech Republic and Poland emerging as the strongest performers, yet with noteworthy contributions from smaller markets such as Croatia, Latvia, and Estonia.
This year’s report also places a spotlight on the Companies to Watch—ten rising stars under four years old that are already defining the future of Central Europe’s tech scene. Lithuanian winner UAB Pulsetto stands out with a remarkable 5,354% growth, offering a wearable device designed to manage stress and sleep by stimulating the vagus nerve. Slovak AI-powered accounting solution Doklado follows in second place, and Poland’s bards.ai, which bridges academic AI research with real-world commercial applications, secures the third position. These companies illustrate the region’s strong commitment to R&D investment, proprietary tech development, and long-term innovation.
Adding another dimension to the 2025 landscape, Deloitte and Google Cloud introduced the inaugural AI Value Driver – CE Rocketship Innovations in GenAI Award, reflecting the fast-growing importance of generative AI in creating real-world value. The first-ever winner, Poland’s Surveily, transforms standard CCTV systems into smart safety-monitoring platforms using advanced computer vision—an innovation aimed at reducing workplace accidents worldwide. Runners-up such as bards.ai, PowereX, Flowpay, and Fluentbe demonstrate the breadth of GenAI’s application, from funding automation to scalable clean-energy solutions. As Google Cloud emphasizes, the rise of these companies signals a new generation of entrepreneurs who prioritise both commercial value and social impact.
A particularly meaningful part of the report is the Impact Stars category, which recognises companies that combine strong commercial products with positive social or environmental contributions. In 2025, 21 companies across fintech, cyber, ESG, defence, and MedTech/BioTech earned this designation. These businesses prove that technology can simultaneously address market needs and contribute to broader societal challenges, from sustainability to public health. As Deloitte’s CE Impact Leader notes, these Impact Stars showcase how young companies increasingly integrate purpose directly into their operating philosophy.
Croatia’s Growing Presence in the Central European Tech Landscape
The 2025 report reveals a notable rise of Croatia within the regional tech ecosystem, marking the country as a growing hub of innovation and high-growth companies. Croatia contributes six companies to the Fast 50 and additional representation in the Companies to Watch and Impact Stars categories—an impressive result for one of the smaller markets in Central Europe. Among the Fast 50, Croatia’s Margins (1,660% growth) and Cactus Code (1,650% growth) stand out as top-performing software firms, while hardware innovator Orqa posts 1,182% growth and further appears in the Impact Stars category for its contributions to defence technology. Other Croatian companies such as Spectral Core, Farseer, B.I.D. Grupa, and Utiliter reinforce Croatia’s position as a growing regional contender. On top of that, Croatian startup Cyber64 secures its place among the Companies to Watch, and three Croatian companies—Aircash, CircuitMess, and Devot Solutions—achieve Impact Star recognition for fintech, ESG, and MedTech/BioTech innovation. Collectively, this strong presence highlights Croatia’s accelerating shift from an emerging market to a significant contributor to Central Europe’s technology future.
Looking ahead, the report suggests that Central Europe’s technology ecosystem is poised for continued evolution. With AI adoption deepening across industries, regulatory environments shifting, and competition accelerating, the companies featured in the 2025 Fast 50 demonstrate that the region’s entrepreneurial spirit remains strong. Even amid global uncertainty, innovation, resilience, and bold ambition continue to define Central Europe’s tech sector. As more companies harness proprietary technology and expand globally, the region’s influence in the broader innovation landscape will only continue to grow.
Seeing how this momentum shapes 2026 and beyond will undoubtedly be fascinating.
