In 2020, European defense and security startups raised less than $1 billion in venture capital. In 2025, they raised a record $8.7 billion. [1] The trajectory was already steep before February 28. Three weeks of war with Iran have turned it vertical.

Reuters published a Breakingviews column on March 17 titled "Gulf money will boost Europe's defence startups," arguing that sovereign wealth funds from the UAE, Saudi Arabia, and Qatar — states with both the capital and the urgent operational need for modern air defense systems — are pouring money into a sector that European institutional investors had largely shunned for ethical reasons. [2] The Financial Times reported on March 4 that 2025's $8.7 billion figure, already a record, was being treated by VCs not as a peak but as a floor. [3] Forbes, on March 3, noted that roughly $19 billion flowed into global aerospace and defense startups in 2025, nearly double the $10 billion raised in 2024. [4]

The Iran war did not create the trend. European defense spending has been rising since Russia's invasion of Ukraine in 2022, and NATO's 2 percent GDP target — now widely considered insufficient — has been pushing member states toward 3 and even 5 percent commitments. What the war did was remove the remaining hesitation. Gulf states that previously invested in European tech for diversification now invest for survival. European governments that treated defense startups as a niche interest now treat them as a procurement pipeline.

Where the Money Goes

The hottest subsectors are counter-UAV systems, autonomous drones, and integrated air defense. Sifted, the European startup publication, profiled twelve defense startups to watch in 2026, ranging from companies building hypersonic interceptors to firms developing micro ocean robots for maritime surveillance. [5] Reuters named Germany's TYTAN and Ukraine's SkyFall as companies positioned to scale if Gulf contracts materialize. [6] The pattern is consistent: technologies that were R&D projects eighteen months ago are now being fast-tracked to production by governments that watched Iranian drones saturate the skies above the Gulf and concluded that their existing systems were inadequate.

Sifted reported on March 3 that the gap between what European defense startups can build and what the Iran war demonstrated is needed remains vast. "Iran, Israel and the US are using military technology that are still R&D-ing Series A startups in Europe," said one VC quoted in the article. [7] The implication is not that European startups are irrelevant but that the timeline for maturity — from prototype to deployable system — has been compressed by a war that is generating real-time demand signals.

The Public-Market Winners

The startup boom has a public-market parallel. Yahoo Finance reported on March 6 that defense-tech stocks were the "hot trade" as the conflict widened. [8] Palantir and CrowdStrike have surged. TIME reported on March 19 that Lockheed Martin, Raytheon, and Northrop Grumman stand to gain a collective $200 billion windfall from procurement demands. [9] The venture market and the public market are responding to the same signal: wars consume materiel, the Western defense-industrial base cannot produce fast enough, and startups fill the gap.

Forbes's Question

Forbes posed the framing question on March 6: "Will the Iran conflict reshape venture capital?" [10] The article concluded that war, by itself, does not restructure a capital market. But war combined with European rearmament, Gulf sovereign wealth deployment, and a generational shift in VC attitudes toward defense creates conditions that look less like a temporary spike and more like a permanent reallocation.

Bessemer Venture Partners published a defense-tech roadmap for 2026 identifying five frontier categories: autonomous systems, space-based surveillance, cyber-physical security, directed energy weapons, and AI-enabled command and control. [11] Each category has startups raising rounds at valuations that would have been laughable in 2023. None of them are laughable now. The money that once chased SaaS metrics is chasing kill chains, and the LPs who once screened out defense on ESG grounds are asking their GPs why they are not allocated.

The war did not create the defense-tech boom. It created the conditions under which the boom became impossible to ignore.
