When people think of Prague, they often imagine narrow historic streets, red rooftops and Gothic churches. Yet this historical beauty now coexists with a modern world of startups and innovation. This is a place where ideas are born that can grow into serious technology companies and even challenge major international players. In this article, we will look at three companies that have made a significant leap over the past 12 months and have become visible far beyond the Czech Republic.
1. “Rezolv Energy”
This startup is trying to solve one of the most pressing problems of our time: how to make renewable energy accessible, reliable and economically sustainable for large businesses without relying on subsidies.
Rezolv is building some of the largest wind farms and solar power plants in Central and South-Eastern Europe. The company develops and manages solar and wind energy projects as well as energy storage systems. By mid-2025, Rezolv had secured record-breaking investments for the region, including a €90 million funding round.
By the beginning of 2026, “Rezolv Energy” manages a portfolio of projects with a total capacity of more than 2 GW. In simple terms, this amount of energy could supply electricity to approximately 1.5–2 million European households.
Behind these numbers are real people — a team negotiating with farming cooperatives, energy companies and municipalities while also addressing climate challenges. In the coming years, Rezolv Energy may significantly influence everyday life by making clean energy more stable and accessible.
2. “Resistant AI”
This company is a strong example of how a Prague-based team can build a world-class product in the high-tech industry. The startup focuses on applying artificial intelligence to combat financial crime and fraud.
“Resistant AI” helps banks, fintech companies and large corporations detect forged documents, complex fraud schemes and suspicious transactions — including those that are only beginning to develop.
In October 2025, the company announced that it had raised $25 million in a Series B funding round. Investors included DTCP Growth, Experian, Google Ventures and Notion Capital, confirming that the company’s product is in demand on the global market.
3. “Choice”
This is a classic story of how a Prague startup identified a major pain point for small businesses and offered a solution that turned out to be globally relevant.
If you live in Prague, there is a high chance that you have already used the product created by “Choice” without even realizing it. QR menus, online payments, tips and loyalty programs are all combined into a single interface for restaurants and cafés.
Over the past 12 months the company has demonstrated impressive growth. After raising $2.5 million in its latest funding round (bringing total investment close to $9 million), Choice expanded far beyond the Czech Republic. Today the company is actively growing in Poland, Hungary and the United Kingdom, as well as several Asian markets. Over the past year, the number of transactions processed through its system has tripled.
Why Prague?
At first glance, three companies from such different sectors — energy, artificial intelligence and restaurant SaaS — may appear unrelated. However, they are connected by the city that has become an innovation hub in Central Europe over the past few years.
Prague offers a strong pool of technical talent, developed infrastructure, acceleration programs and international connections. In 2025, the Czech government also introduced several tax incentives for technology companies, allowing startups to retain more capital within the business for development and scaling.
