Deep33 Secures $100M for US–Israel AI & Quantum Tech Investments
Synopsis- Deep33 launches with a $100 million first close to back AI, quantum, energy, and robotics infrastructure.
- The fund targets strategic deep tech bottlenecks across the US and allied markets, with a strong US–Israel focus.
- Founders cite an “AI SuperCycle” driving unprecedented private and public investment momentum.
Deep33 has entered the venture capital landscape with a $100 million first close, positioning itself to shape the next phase of artificial intelligence and quantum technology development. The newly formed fund is structured around a $150 million target and is focused on companies building foundational infrastructure across the United States and its allies, with particular emphasis on the US–Israel technology corridor.
According to reporting by Calcalist Tech, the firm has already invested in five companies spanning quantum computing and advanced energy, while two additional portfolio companies are operating in stealth. The strategy reflects what Deep33’s founders describe as a rapidly emerging set of infrastructure constraints that could slow progress in AI, quantum computing, robotics, and next-generation energy systems if left unaddressed.
“The decision to establish the fund came after many months of in-depth research to identify the areas where immediate investment will be required in the coming years in order for the West, led by the United States, to win the AI race,” said managing partner Lior Prosor.
The fund is co-founded by Prosor, formerly a partner at Hanaco, and Michael Broukhim, a serial entrepreneur and investor with prior exposure to companies including Stripe and SpaceX. Deep33 has assembled a team that blends technical, entrepreneurial, and intelligence expertise. Col. (res.) Joab Rosenberg, a quantum physicist and former commander of Israel’s Talpiot program, leads quantum investments, while Ori Amsalem oversees energy initiatives and Maj. (res.) Yael Barsheshet directs AI infrastructure investments.
Deep33’s investment thesis is anchored in what its leadership refers to as the “AI SuperCycle.” The founders point to more than $1 trillion already committed by major technology companies toward artificial intelligence development, with $315 billion allocated for 2025 alone. This private-sector surge is reinforced by substantial US government spending through federal budgets and grant programs, underscoring the strategic importance of AI and quantum capabilities.
Among the fund’s early and stealth investments are a company developing sustainable fuel production methods designed to eliminate dependence on oil and toxic by-products, and another focused on optimizing GPU utilization to increase computing efficiency while lowering AI infrastructure costs. Publicly disclosed investments include quantum companies QuamCore and CyberRidge, as well as energy innovator Particle.
Deep33 expects to complete its $150 million raise within the current quarter. Arkin Capital, led by Nir Arkin, is cited as a major investor. The fund’s leadership characterizes the current environment as “the largest investment cycle ever,” driven by geopolitical competition, infrastructure demand, and accelerating AI deployment across industries.
As noted in Calcalist Tech, Deep33’s approach departs from traditional venture capital by prioritizing domain-specific expertise and long-term infrastructure readiness over short-term growth narratives. The fund’s portfolio construction reflects a deliberate effort to secure technological leadership in areas viewed as decisive to future economic and security outcomes.
