XISTA Science Ventures is the independent venture arm of the XISTA ecosystem, investing in science-driven companies built on deep research, with a focus on human health and industrial technologies. It supports researchers and founders with early exposure to the venture path, focused incubation, mentoring, practical training, lab and office space, and early investment for teams advancing life science and engineering projects. The firm invests in deep-tech and life-science startups and academic spin-offs, including companies from Austrian research institutions, and describes its portfolio and activity across biology, chemistry, materials, physics, computational sciences, and AI. Its portfolio companies have raised more than €250 million in grants and equity funding, and XISTA says its current fund is €70 million; XISTA also states that Fund I is fully deployed and Fund II is actively investing. XISTA is anchored at the Institute of Science and Technology Austria, and a Vienna Business Agency profile places it in Vienna; another source says XISTA Science Ventures is located at XISTA Science Park in Klosterneuburg.
