Deep tech in Europe

Funding into European deep tech startups has grown nearly tenfold over the past five years, reaching $20.3B in 2025. With $23.5B raised in the first 6 months of 2026, the full year is on track to land at $47.0B, a +131% change versus 2025. The chart below shows annual funding totals; the latest year is annualised from observed-to-date data and represents the renderer's projection, not a closed quarter.

Yearly totals mask the quarter-by-quarter rhythm. The chart below shows European deep tech startups funding raised in each of the last 21 complete quarters through Q2 2026. All bars are actual closed-quarter sums, no projections, no in-progress quarters.

European deep tech's share of global deep tech venture capital tracks how much of global deep tech's startup capital lands in this market. In 2016, European deep tech startups accounted for 19.5% of global deep tech VC funding; by 2026 the share had reached 6.6%. The chart below splits each year's total global deep tech VC funding into European deep tech on the bottom and the rest of the market on top.

How capital deployed into European deep tech startups is split across round sizes. In the trailing four quarters, 68% of capital landed in scaleup ($100M+) rounds, 23% in breakout ($15–100M), and 10% across startups (under $15M). Each panel below stacks the canonical sub-bands across Q2 2022 → Q2 2026.

The most active investors in European deep tech startups ranked by the number of disclosed rounds they've participated in. Bpifrance leads with 450 rounds, followed by Venture Kick at 422. The table shows the top ten with their firm type, in-scope round count, total portfolio size, and headquarters.

Over the last 12 months (through Jul 2026), the largest VC rounds in European deep tech startups reveal where capital is consolidating. The table below lists the 15 biggest disclosed rounds by amount, with date, company, round type, and lead investors. Funding events without a public amount are excluded; acquisitions sit in the Unicorns & Exits section.

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 193% over three years to $4.3B in 2025 and 16 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 120 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, 10 are decacorns, companies at a $10B+ valuation. The ecosystem also counts 68 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 20 in 2021. On exits, the sector has produced 1,065 tracked acquisitions since 2010 representing $49.8B in disclosed value. Notable acquisitions in the data include Darktrace ($5.3B, 2024), followed by ARM ($4.9B, 2023), Sophos ($4.1B, 2019).
