Which corners of European deep tech are heating up fastest? Each sub-sector is scored on a transparent blend of two-year VC growth, unicorn formation, and recent funding scale. Quantum Computing tops the ranking, with venture capital up 194% over three years to $4.3B in 2025 and 18 unicorns. Sub-sector tags overlap (a company can sit in several), so this shows where momentum concentrates rather than splitting the total.

European deep tech startups have minted 131 unicorns to date. Dealroom defines a unicorn as a company that has reached a $1B+ valuation or exit (verified and manually reviewed; other lists use different criteria, this is ours). Of those, 15 are decacorns, companies at a $10B+ valuation. The ecosystem also counts 71 thoroughbreds: companies generating $100M+ in revenue (a separate lens from unicorns, with some overlap). The chart below shows the cumulative count climbing each year, with the line tracking new unicorns minted in that year, peaking at 30 in 2026. On exits, the sector has produced 964 tracked exits since 2019 representing $167.4B in disclosed value. Notable exits in the data include ARM ($54.5B, 2023), followed by Oatly ($13.0B, 2021), Arrival ($13.0B, 2021).
