Sifted 250: Only One Austrian Startup Among Europe's Fastest Growing
The Sifted 250, presented at Sifted's Summit in London, ranks Europe's fastest-growing startups by revenue growth over three years, favoring young companies with smaller revenue bases and excluding acquired ones. Only one Austrian startup, Salzburg-based Bitcoin app 21bitcoin, made the list, placing 107th with nearly 210% annual growth—contrasting with Austria's record H1 funding of €472 million. London's Healf tops the ranking with approximately 1,400% annual growth, followed by Neko Health and Aikido Security. The list highlights a shift toward AI-native companies (56, more than double last year), B2B software dominance (81 companies), and improved efficiency, with revenue per employee doubling to €337,000. Austria's weak representation is attributed to funding structure, deep tech focus, and exits like Tractive's sale. Sifted acknowledges limitations, including reliance on self-reported data.
