A busy 24 hours for AI and deep-tech money, from a $300m quantum bet to Paris voice AI and Europe’s energy startups. Here are the rounds worth knowing. The cash keeps flowing into AI and deep tech. The past day alone brought a $300m quantum raise, a fresh billion-dollar https://thenextweb.com/news/lovable-build-economy-500m-arr-vibe-coding AI-agent valuation, and European bets on voice and energy. Here are the most interesting rounds from the last 24 hours. The heavyweight raises Oratomic, $300m Series A. The quantum-computing https://thenextweb.com/news/quantum-systems-1-2bn-series-d-8bn-valuation startup landed one of the sector’s largest early rounds on 7 July. ARCH Venture Partners, Spark Capital and Khosla Ventures co-led, The Quantum Insider https://thequantuminsider.com/2026/07/07/oratomic-raises-300-million-series-a/ reported. Led by CEO Dolev Bluvstein, it only launched in late March. It is chasing fault-tolerant, utility-scale quantum machines, built on neutral-atom technology developed with Caltech. Prime Intellect, $130m Series A. The two-year-old startup hit a $1bn valuation on 8 July, TechCrunch https://techcrunch.com/2026/07/08/prime-intellect-raises-130m-series-a-to-help-enterprises-build-their-own-ai-agents/ reported. Radical Ventures led, with Nvidia Ventures and Intel Capital joining. It sells computing power and tools that let companies train their own AI agents, no frontier lab required. The pitch targets firms wary of depending on OpenAI or Anthropic. Europe’s bets Gradium, seed past $100m. The Paris https://thenextweb.com/news/mistral-ai-2bn-dollar-valuation-less-than-12-months-founding voice-AI startup, a spinout of the Kyutai lab, added about $30m from new backers including Nvidia. That takes its seed beyond $100m, Sifted https://sifted.eu/articles/gradium-nvidia-30m-extension-seed reported. Nvidia’s repeat appearance is the tell. The chip giant keeps buying into the startups building on its hardware https://thenextweb.com/news/sambanova-11-billion-valuation-ai-chips . Axle Energy, €21m Series A. The London firm turns EV chargers, home batteries and heat pumps into grid-balancing capacity. It raised from Energize Capital and Accel, Sifted https://sifted.eu/articles/accel-axle-25m/ reported. It rides the same wave pushing utilities and data centres to find flexible power. Bizay, $55m Series D. The Lisbon marketplace for custom-printed products for small businesses raised from Indico, Tech.eu https://tech.eu/2026/07/07/bizay-secures-55m-to-fuel-us-growth-and-industry-consolidation reported. The cash funds a US push and more AI across the platform. Why it matters The through-line is where investors think the next edge sits. Quantum and AI agents pull the biggest cheques https://thenextweb.com/news/decart-300-million-radical-ventures-world-models , while Europe’s money flows to the unglamorous plumbing, voice and energy, rather than another chatbot. Note Nvidia turning up in two of these rounds, funding the ecosystem it already dominates. As valuations stretch, the test now is which raises buy real revenue, and which just buy time.
