Estonia is back in the top tier of Deloitte’s Technology Fast 50 Central Europe 2025, confirming its rising influence on the region’s innovation map. At the awards gala in Prague on November 20, Tallinn-based fintech Wallester was revealed as the highest-ranked Estonian company, placing 6th overall among the fastest-growing tech firms in Central Europe.
The Deloitte Fast 50 program spans nine countries – Estonia, Latvia, Lithuania, Poland, Czechia, Slovakia, Romania, Croatia, and Ukraine – and recognises technology companies (public or private) with the strongest percentage revenue growth over a four-year period.
“A Top-10 Return for Estonia”
Wallester’s strong showing signals more than corporate success: it underlines Estonia’s comeback to the Fast 50 top 10, underscoring the country’s growing weight in Central Europe’s tech ecosystem.
According to the official Deloitte ranking, Wallester achieved a 2,070% revenue growth over the past four years – a performance that made it the top Estonian on the list and one of just three fintechs in the top 10.
In 2019, Estonian company Cleveron also broke into the top 10, signalling the country’s early-scale-up potential. Wallester’s success now marks a return to that elite club, underscoring long-term momentum in the Estonian tech ecosystem.

Estonia’s Innovation Momentum
Estonia has long punched above its weight in European tech, and this recognition reinforces that narrative:
- The country has one of the highest startup densities per capita in Europe.
- Its digital-first national infrastructure – including e-Residency, paperless government, and zero corporate tax on reinvested profits – continues to fuel scalable tech businesses.
- According to the State of European Tech 2024 report, over the past decade, Estonia’s tech workforce has increased almost tenfold, bolstering its status as a significant innovation hub.
These dynamics create fertile ground for scale-ups like Wallester to thrive.

“This is a huge achievement and a clear recognition of the work we all do every single day,” said Sergei Astafjev, CEO & Co-Founder of Wallester. “Five years ago, we were five people in one small room. Today, we are among the fastest-growing tech companies in the entire region.”
Looking Ahead
The rise of Wallester, alongside increasing representation of Baltic companies in the Fast 50, signals a broader shift: smaller European economies are no longer peripheral, they’re central to the region’s innovation map.
As embedded finance and digital infrastructure mature, Estonia is proving it can compete with Europe’s biggest scale-up markets. “This achievement highlights the incredible growth of Baltic tech companies, making their mark across Central Europe. Your success continues to inspire the region’s thriving tech ecosystem,” highlighted Deloitte.
Two other Baltic companies appear in the main list: Latvia’s SIA Prime Prometics (#14) and Estonia’s Hacken (#37). In the Companies to Watch category, Lithuania’s UAB Pulsetto and Latvia’s GRAIP were also highlighted, while Biomatter Design (Lithuania) and Origin Robotics (Latvia) appear in this year’s Impact Stars.
