hands-on support for hard-tech founders HAX is a part of SOSV, the world’s most active pre-seed deep-tech venture capital firm. How HAX Helps Hard Tech Founders Rapidly Prototype, De-Risk Technology & Achieve Traction AXIOS Unspun Raising $40M For Low-waste Weaving Machines & Partners with Major Brands SPACE NEWS Aspect Aerospace Raises $2.4M To Develop Single-Board Satellites for Space-Based Environmental Monitoring for pre-seed startups solving hard problems with hard tech HAX is the world’s first and most active program built for pre-seed startups working at the intersection of science and engineering, where real-world, industrial-scale problems need more than software and slide decks. That’s exactly where HAX operates. We seek founders tackling the hardest physical challenges of our time, across plasma, critical minerals, climate infrastructure, chemistry, robotics, and advanced manufacturing.

At SOSV HAX, we build an entire engineering organization around you. In addition to up to $550K in pre-seed funding, we provide a six-month residency at our 35,000 square-foot facility in Newark, NJ – steps from major finance, research, and industrial hubs. Founders gain access to the space, tools, and technical depth needed to turn research into prototypes, and prototypes into real products. Complementing the Newark operation are HAX’s design, engineering and manufacturing experts in Pune and Shenzhen. 440 HAX Startups $550K Initial Investment $11B HAX Startups Total Value $225M+ SOSV Investment to HAX Startups $1.5B SOSV Total AUM $3.5B HAX Startups Total Fundraising new opportunities in plasma SOSV HAX is growing again. Together with the Princeton Plasma Physics Laboratory and the New Jersey Economic Development Authority, we’re developing the HAX Plasma Forge in Princeton, a new initiative designed to give founders access to world-class plasma physics expertise. Plasma is redefining what’s possible across manufacturing, materials, semiconductors, and energy. The HAX Plasma Forge will provide plasma founders with an unparalleled opportunity to build faster. a seasoned team of scientists & engineers Led by Duncan Turner, SOSV General Partner and HAX Managing Director, and Avra van der Zee, SOSV General Partner, SOSV HAX is powered by a global team that blends rigorous scientific training with real-world commercial experience. Our team knows what it takes to validate technology in industrial environments, navigate manufacturing constraints, and shape complex technology into investor-ready narratives. We work alongside founders to pressure-test ideas, refine the science, and accelerate toward market traction. It’s a hands-on, deeply technical partnership that starts on day one and continues long after the initial residency. founder community → join the founder community by applying to a HAX program
