Updated August 2026. By Remy Beaumont.
Total raised in Europe this week: approximately €345m across 18 disclosed rounds.
Key takeaways
The week was quiet by European standards, driven by the UK bank holiday on Monday 25 August and lighter late-August deal flow across the continent.
Legora, the Stockholm-based AI legal platform, was reportedly in advanced talks for a new raise at a $15.5bn valuation, though no closed round was confirmed this week. The legal tech sector continues its rapid capital absorption across Europe.
The UK-Ukraine AI partnership agreement, signed on 25 August, was the most significant policy development of the week, committing both governments to joint development of AI technologies with defence and civilian applications.
Callosum, a UK-based deep computing startup, raised £73.5m ($95m) the prior week, and the announcement continued to generate coverage into this window. Its ambition to "redefine how humanity computes" drew attention for both its scale and its framing.
Berlin-based Kazimi raised €2.6m in pre-seed funding for mobile-app cybersecurity, led by Market One Capital with IBB Ventures, reflecting continued seed-stage activity in European cybersecurity.
Itoflow, a London-based AI portfolio management platform, raised £1.8m ($2.5m) from Balderton Capital, one of several UK seed rounds that landed during the bank holiday week.
What did the EU funding week look like?
The week ending 25 August 2026 was the quietest European funding week in at least a month. The UK bank holiday on Monday combined with typical late-August continental deal flow patterns to produce a thin week. Deal aggregators had not published a European weekly wrap at time of writing, and the rounds that did surface were predominantly seed and pre-seed.
For the month-level picture, see our monthly roundup of the biggest EU funding rounds.
This is the inverse of a mega-round week. No single deal exceeded $100m. The largest confirmed rounds from the window were carry-over coverage from the prior week (Callosum at £73.5m, announced 20 August) and smaller UK and Nordic seed rounds. For founders who raised in this window, the upside is clear: there is far less competition for press coverage when a $65bn Anthropic round is dominating the US news cycle and no European mega-deal is pulling the domestic tech press.
Which was the biggest EU round this week?
No single confirmed European round this week exceeded $100m. The most significant capital story was the continuation of Callosum's £73.5m raise announced on 20 August. The UK-based deep computing startup's round drew attention for its scale at Series A stage and its ambition to build fundamentally new computing architectures.
The lack of a clear headline deal this week is itself informative. European mega-rounds in 2026 have tended to cluster, with the Lovable ($400m) and Cambridge Aerospace ($300m) rounds of the prior fortnight followed by a comparative lull. This rhythm, burst then pause, is structural in European venture: the smaller pool of growth-stage funds means that when two or three large rounds close in quick succession, the deployment pipeline needs to refill.
For European founders timing their announcements, this pattern creates a practical opportunity. Quiet weeks have less press competition. If your round does not need the gravitational pull of a larger deal to generate coverage, announcing during a lull can produce disproportionate attention.
Noteworthy EU rounds and developments this week
Kazimi, €2.6m pre-seed, Berlin, Germany. Mobile-app cybersecurity startup Kazimi raised €2.6m led by Market One Capital with IBB Ventures and angel investors. The company focuses on protecting mobile applications from reverse engineering and tampering, a niche that has grown with the expansion of fintech and health apps across the EU. Market One Capital, a Warsaw-based fund, leading a Berlin deal is a micro-example of intra-European cross-border investing that happens constantly at seed stage but rarely generates headline attention.
Itoflow, £1.8m ($2.5m) pre-seed, London, UK. AI-powered portfolio management platform for investment teams. Balderton Capital led the round with angel investors. The company appeared in Fortune's Term Sheet deal digest on 25 August, an unusual distribution channel for a pre-seed UK round. The Balderton imprimatur carries weight in UK institutional circles, and the Fortune pickup suggests the company or its advisors actively placed the deal item in US-facing deal digests. This is a low-cost distribution tactic worth noting: placing a deal item in a US newsletter like Term Sheet or StrictlyVC costs nothing and generates signal with US LPs and potential US customers.
Embedd, £2m, UK. Infrastructure for physical AI, announced 25 August. The round was small but positioned in one of the fastest-growing AI sub-sectors. Physical AI startups globally attracted $47.4bn in H1 2026 across 521 deals, per Crunchbase data.
Medly, £6m, UK (announced 19 August, continued coverage). AI tutor startup for exam preparation. The round was announced mid-week prior but generated bank holiday week coverage in UK tech press. Education AI remains a consistent seed and Series A category in the UK.
Scottish data centre group, £25m expansion (announced 24 August). A Scottish data centre operator secured £25m to expand AI computing capacity. The deal reflects the UK's push to build domestic AI infrastructure outside the London-Cambridge corridor.
Where is EU capital flowing?
The week's disclosed rounds were overwhelmingly concentrated in AI and cybersecurity at seed and pre-seed stage. There was no growth-stage European round confirmed in the Aug 22-26 window at $50m or above. This is unusual but not unprecedented for a late-August bank holiday week.
The sector breakdown for the disclosed rounds:
AI and machine learning: Itoflow, Embedd, Medly, Scottish data centre expansion
Cybersecurity: Kazimi
Deep tech / computing: Callosum (carry-over from prior week)
Legal tech: Legora (reported as in talks, not confirmed closed)
The UK dominated deal count again, with Itoflow, Embedd, Medly, and the Scottish data centre investment all UK-based. Berlin produced Kazimi. Stockholm and the Nordics were quiet, a notable shift from the prior two weeks when Lovable dominated.
The UK-Ukraine AI partnership
The most significant European development of the week was not a funding round but a policy agreement. On 25 August, the UK and Ukraine signed a landmark AI partnership to develop new technologies jointly. The agreement covers both defence and civilian applications and positions the UK as a leading Western partner in Ukraine's post-conflict technology reconstruction.
For defence tech founders across Europe, this is a commercial signal as much as a policy one. UK government procurement in AI-enabled defence systems is expanding, and the Ukraine partnership creates a potential testing and deployment pathway for UK-developed technology in active operational environments. Cambridge Aerospace, which raised $300m the prior week, is the most visible beneficiary of this trajectory, but the agreement opens doors for a wider ecosystem of smaller UK defence AI startups.
What should EU founders raising soon do this week?
Use bank holiday quiet weeks to your advantage. If you have a round to announce and it does not need mega-deal gravity to generate coverage, a quiet week like this one offers less competition in both UK and continental tech press. UKTN, for example, covered Embedd (£2m) and Itoflow (£1.8m) with dedicated articles because there was no larger deal competing for the homepage.
Place deal items in US newsletters. Itoflow's appearance in Fortune's Term Sheet, as a £1.8m London pre-seed, demonstrates that US deal digests will include small European rounds if the deal is positioned correctly. This is free distribution. If you have raised from a recognisable fund (Balderton, Accel, Index, Atomico), the fund name does the work of making the deal newsworthy for a US audience.
Watch the legal tech deployment cycle. Legora at $5.5bn, Harvey reportedly seeking $500m at $15.5bn, and Clio having raised $1.4bn in two years, the legal AI sector is absorbing capital at a rate comparable to fintech in 2021. If you are building in adjacent professional services AI (accounting, consulting, compliance), the legal tech valuations are setting the ceiling for your comps.
Track the UK-Ukraine AI partnership for procurement signals. The agreement is new and specific implementation details are not yet public. But for UK defence tech founders, it is a strong directional signal that HMG is expanding its AI procurement scope and its international deployment partnerships simultaneously.

Frequently asked questions
What was the biggest EU funding round this week? No single confirmed European round exceeded $100m in the week ending 25 August. The most significant capital story was the continuation of Callosum's £73.5m raise from the prior week.
How much did European startups raise in total this week? Approximately €345m across 18 disclosed rounds for the week ending 25th August 2026, including carry-over announcements. This is significantly lower than both the prior week and the August average.
Why was European funding so quiet this week? The UK bank holiday on Monday 25 August, combined with typical late-August continental deal flow patterns, produced a structurally thin week. Growth-stage European rounds tend to cluster and then pause, and the prior fortnight's Lovable and Cambridge Aerospace rounds may have absorbed available growth-stage capital deployment for the period.
What was the UK-Ukraine AI partnership? Signed on 25 August, it commits both governments to joint development of AI technologies with defence and civilian applications. Specific implementation details were not disclosed at signing.
How does this week's European funding compare to the US? US funding this week ($67.8bn) was dominated by Anthropic's $65bn raise. European funding (approximately €345m) was quiet by comparison but also by its own recent standards. For US funding detail, see our US funding roundup for the same week.
