Sebastian Kurz’s Cybersecurity Start-up Valued at $3B
Former Austrian chancellor Sebastian Kurz co-founded Dream, an AI-focused cybersecurity company, which said it closed a $260 million Series C financing that values the business at $3 billion. Kurz holds a roughly 15% stake in the company. Dream describes itself as a provider of AI for states and critical infrastructure and employs about 350 people across Vienna, Abu Dhabi and Tel Aviv, with headcount nearly doubling over the past year. The Series C was led by Bicycle Capital and Group 11, with participation from Bain Capital, Tru Arrow Partners (including investor James Rothschild) and Antler. Kurz commented publicly on strategic national AI ownership and warned that future cyber conflicts will be AI-driven. The article was published 2026-06-18.
A large late-stage funding ($260M) and $3B valuation for an AI-focused cybersecurity start-up is notable for AI and security investors but is not industry-shifting for the broader AdTech/MarTech ecosystem.

Horizon3 Raises $250M Series E at $2B Valuation
Horizon3, a San Francisco-based cybersecurity startup, raised $250 million in a Series E at a $2 billion valuation. Returning investors NightDragon and NEA participated, and new strategic backers include Singapore’s EDBI, defense contractor SAIC, and Qualcomm. Horizon3 says it is approaching $100 million in annual recurring revenue with 120% year-over-year growth, has run 310,000 production security tests with no disruptions, and has invested roughly $100 million in R&D to build automated, controllable security testing. Its NodeZero platform performs continuous, live scans across full infrastructures without shutting down operations. The funding will support international expansion (Amsterdam, Australia, Singapore), partner network development, and continued R&D amid rising AI-driven attack concerns and recent AI model breaches at research labs.
Socher & Rocktäschel's $650M AI bet
German AI researchers Richard Socher and Tim Rocktäschel have launched a new start-up, Recursive Superintelligence (RSI), and raised $650 million at a $4.65 billion valuation. RSI — founded by Socher, Rocktäschel and six co‑founders — aims to build an AI that largely performs AI research itself and to scale toward so‑called “superintelligence” within about two years. The newsletter also reports several other technology and funding items: AppliedAI founder Arya Bolurfrushan was sentenced to two years in prison for insider trading and ordered to repay nearly $1 million; Munich fusion start‑up Proxima Fusion raised €411 million valuing it at €2.4 billion; QuantumDiamonds raised €91 million led by World Fund; and Microsoft’s Xbox division announced around 3,200 job cuts. The piece is a July 10, 2026 tech newsletter roundup covering funding, executive news, and industry developments.
Mistral Secures €3B Series D for Sovereign AI
Mistral AI, a Paris-based company, raised €3 billion (~$3.5 billion) in a Series D round, reaching a post-money valuation exceeding €21 billion (~$24 billion), marking the largest equity financing ever by a European tech firm. Led by Samsung Electronics, with co-leads EQT's Scaleup Europe Fund and PSG Equity, the round attracted new investors Advent, BlackRock-managed funds, and Luxembourg, plus existing backers ASML, NVIDIA, Andreessen Horowitz, and others. The funds will advance R&D, computing capacity, and global expansion, shifting focus toward AI infrastructure, data centers, and sovereign compute via Mistral Compute. This intensifies competition with European neocloud rivals Nebius and Nscale. Notably, for the first time, a non-European entity leads the round, possibly indicating a broader coalition of middle powers in European AI sovereignty. Mistral serves over 125 enterprises across 20 countries, including Airbus and HSBC, targets 1 GW data centers by 2030, and expects ARR to exceed $1 billion this year.
