Venture Capitalists and Editors Curate 21 European Deep Tech Startups for the AI Race

TechCrunch has published a curated list of 21 European startups recommended by venture capital investors and editors for observation in the artificial intelligence and deep tech sectors. Titled "Beyond Lovable and Mistral: 21 European startups to watch," the compilation was released on 2 May 2026 to highlight companies that insiders are tracking closely despite not yet having nine digits in annual recurring revenue.

The selections span various stages of development, from pre-launch ventures to unicorns, and cover diverse industries including defence, aerospace, fusion energy, robotics, and finance. The methodology involved asking partners from prominent European venture funds to nominate two companies each—one from their portfolio and one outside it—alongside a few editorial picks. Due to this approach, the list may not reflect where the region's hottest hubs are, but it does reflect how deep tech talent could help Europe play its own cards in the AI race.

Specific highlights include Alta Ares, a Prague-based team developing AI-powered counter-drone systems. The venture is noted as a response to the need for cheaper drone interception solutions in Europe, where defence technology has shifted from pariah to trending following the war in Ukraine. Another key entry is Fundamental, which launched its foundation model 'Nexus' in February 2026 and is valued at $1.4 billion following a $255 million Series A.

The list also emphasises a strategic shift towards generative engine optimisation (GEO) replacing traditional SEO, with companies like Botify already embracing the change. Furthermore, there is a significant increase in focus on defence tech and investment in fusion energy and in-space manufacturing. Proxima Fusion, for instance, secured $460 million from the state of Bavaria to build a demonstration stellarator near Munich, competing in the race for alternative nuclear fission.

Other notable entries include PLD Space, a Spanish company developing a reusable orbital launcher for small satellites that recently secured a $209 million Series C round led by Mitsubishi Electric. Space Forge is also featured for recently generating plasma in low Earth orbit, focusing on manufacturing semiconductor components in space. The cohort includes firms like BottleCap AI, which builds efficiency-focused foundational LLMs, and HappyRobot, backed by a16z and Y Combinator, which focuses on deploying AI agents that deliver ROI.

The compilation underscores a broader trend where European startups are leveraging advanced research in photonics, renewable energy management, and legal tech to address specific market needs. While some entities like Legora are headquartered in New York, they are described as rising stars from Stockholm, illustrating the complex geography of modern deep tech investment. The list serves as a snapshot of the diverse ecosystem that venture capitalists believe will define the next phase of the European technology landscape.
