Wallester has been ranked 231st on the 2025 Sifted 250, a prestigious list recognising Europe’s fastest-growing startups by revenue.
Now in its second year, the Sifted 250 highlights companies that are not only scaling rapidly but also proving genuine market demand for their products. Compiled by Sifted’s Intelligence team, the ranking measures compound annual revenue growth (CAGR) over the latest three financial years – making it one of the most data-driven indicators of sustained business performance in the European startup ecosystem.
To qualify, startups must be:
- Private and independent
- Headquartered in Europe
- Generating the majority of revenue from proprietary technology
- Founded in or after 2010
- Reporting at least three years of financial data verified through supporting documentation
This year’s list underscores the strength and maturity of Europe’s startup ecosystem. Collectively, the companies ranked generated €6.3 billion in revenue in their latest financial year – with the average company achieving €25.3 million in annual revenue and a 54% increase in revenue per employee compared to last year’s cohort.

Sustained Growth and Market Demand
