Deep33 has launched with a $100 million first close fund, poised to significantly impact the future of artificial intelligence and quantum technologies. The new venture capital firm will focus on deep tech companies building critical infrastructure within the US and its allies, particularly along the US-Israel corridor. Already backing five startups, Deep33 aims to address emerging bottlenecks in quantum computing, AI infrastructure, advanced energy, and robotics. “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,” explains Lior Prosor, the fund’s managing partner. Deep33 anticipates completing its planned $150 million raise this quarter, capitalizing on what its founders call “the largest investment cycle ever.”
Deep33 Fund Launches with $100 Million First Close
A new $150 million venture capital fund, Deep33, has secured an initial $100 million to fuel innovation in technologies deemed critical to the infrastructure of the United States and its allies. The fund’s focus extends beyond typical venture capital, targeting quantum computing, artificial intelligence infrastructure, advanced energy, and robotics – areas identified as potential bottlenecks in near-future technological advancement. Already, Deep33 has deployed capital into five startups spanning quantum and energy sectors, with two additional companies operating in stealth mode.
Founders Lior Prosor, formerly a partner at Hanaco, and Michael Broukhim, a serial entrepreneur with investments in companies like Stripe and SpaceX, assembled a team of experts drawn from both technological and intelligence backgrounds. Col. (res.) Joab Rosenberg, a quantum physicist and former commander of the Talpiot program, will lead the fund’s quantum investments. Deep33’s investment thesis is predicated on what they term the “AI SuperCycle,” noting that tech giants have already committed over $1 trillion to AI, with $315 billion earmarked for 2025 alone. This is coupled with substantial U.S. government investment through budgets and grants.
One stealth startup is focused on sustainable fuel production, eliminating reliance on oil and toxic waste, while another is optimizing GPU utilization to reduce costs and improve AI computing power.
AI SuperCycle Drives $1 Trillion Tech Investment
A surge in technological investment, dubbed the “AI SuperCycle,” is fueling a projected $1 trillion influx into artificial intelligence development, according to the founders of the newly launched venture capital fund, Deep33. This massive commitment from tech giants like Amazon, Microsoft, Apple, and Google—with $315 billion allocated for 2025 alone—signals an unprecedented era of AI-driven innovation. One undisclosed startup is pioneering sustainable fuel production, while another is developing AI infrastructure designed to maximize computing power and reduce operational costs. “Based on the research we conducted, we developed a comprehensive investment thesis on which the fund was built, and partners with expertise in these fields were recruited,” Prosor added.
Domain Expertise Guides Quantum, Energy, AI Infra Investments
Deep33, a newly launched venture capital fund, is strategically deploying capital based on specialized knowledge within emerging technologies, targeting a total raise of $150 million. Having already secured a $100 million first close, the fund anticipates completing its fundraising during the current quarter, with Arkin Capital, led by Nir Arkin, as a major investor. This financial injection isn’t simply about funding innovation; it’s a calculated move to address impending infrastructural challenges in critical sectors. The fund’s leadership emphasizes a proactive approach to securing Western leadership in artificial intelligence.
This research has informed a “comprehensive investment thesis” and driven the recruitment of partners with focused expertise. Deep33’s portfolio reflects this strategy, already including investments in quantum firms QuamCore and CyberRidge, and energy innovator Particle. Beyond these, two stealth startups are receiving support: one developing sustainable fuel production, and another focused on optimizing AI infrastructure to enhance computing power and reduce costs. Specialized leadership further bolsters this domain-driven approach, with Col. (res.) Joab Rosenberg heading the quantum division, Ori Amsalem leading energy investments, and Maj. (res.) Yael Barsheshet overseeing AI infrastructure.
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.
