Europe’s fastest-growing startups don’t succeed in a vacuum — behind them are the investors who spot their potential early, provide the capital to scale and offer the strategic guidance needed to navigate high-growth challenges.
Alongside the Sifted 100: UK & Ireland 2025 Leaderboard, which ranks the 100 fastest-growing startups by revenue growth, we’ve identified the investors backing the region’s most successful companies. Investors are ranked by the number of portfolio companies on the leaderboard in the first instance, followed by the average two-year revenue CAGR of those companies. This list highlights the 125 investors with at least two companies on the leaderboard.
For fund focus, we’ve categorised investment stages as “Early” for investments from pre-seed up to Series A, “Growth” for Series B and C and “Late” for investments from Series D onwards.
