Founded in 2023 by Jordi Parramon, PhD and William Marks, MD and with the addition of Jon Lundt, PhD and John Propst, PhD, MBA, the firm brings a deep commitment to developing technologies to help those with neurodegenerative, neuropsychiatric, and neurodevelopmental disorders, such as Parkinson’s disease, bipolar disorder, and autism spectrum disorder. Adjacent to these sentinel disorders are many other brain disorders that are also within scope for Nexus NeuroTech Ventures.
Prior to this role, Jordi served as President, Medical Devices at Verily Life Sciences (Alphabet’s healthcare company, formerly Google Life Sciences), where he was responsible for leading Verily’s Medical Devices business, combining hardware, software, and AI/ML to create differentiated and clinically validated solutions for Verily’s clinical research products and healthcare products, as well as external research and commercial partnerships and joint ventures.
Before joining Verily, Jordi spent twelve years at Boston Scientific, ultimately serving in the role of Director of R&D, Neuromodulation, bringing to market various generations of implantable products for the Chronic Pain (Spinal Cord Stimulator) as well as the Movement Disorders/Parkinson’s Disease (Deep Brain Stimulator) franchises. Jordi started his career at Advanced Bionics where he was a key contributor on advanced technology for neuromodulation. Jordi holds 200+ worldwide patents with 60+ distinct patent families and earned a Ph.D., M.S., and B.S. in Electrical Engineering and a B.S. in Physics from the Universitat Autònoma de Barcelona.
Prior to this role, Bill served as Head of Clinical Science and Head of Neurology at Verily Life Sciences (Alphabet’s healthcare company, formerly Google Life Sciences). At Verily, he was responsible for the team of physicians, other clinicians, and scientists who provide clinical and scientific expertise across the company. For neurology, Bill led Verily’s efforts to advance the understanding of neurological disorders and improve patient outcomes–including extensive work focused on Parkinson’s disease. Previously, Bill had a distinguished academic career at UCSF, where he was Professor of Neurology and his research and clinical work emphasized technology-based solutions, such as neuromodulation. He is now Adjunct Clinical Professor of Neurology & Neurological Sciences at Stanford University School of Medicine.
Bill received an Honors Bachelor of Science degree in Biology from Marquette University and his Medical Degree from the Johns Hopkins University School of Medicine. He completed his neurology residency and fellowship at the University of California, San Francisco (UCSF). Bill also holds a Master of Science in Healthcare Management degree from the Harvard School of Public Health.
Jon Lundt serves as a Principal at Nexus NeuroTech Ventures, focusing on Series A through growth-stage opportunities in medical devices, basic neuroscience research tools, diagnostics, and tech-enabled care services. Prior to joining Nexus, he served as a Senior Associate at RA Capital Management, where he supported the build-out of its Health Technologies and Services team and served as a board observer for Exo Imaging and Nodexus. Prior to RA, Jon completed the Venture Creation Fellowship program at Flagship Pioneering and interned at Arboretum Ventures.
Jon earned a Ph.D. in Biomedical Engineering from the University of Michigan where he performed research on histotripsy, a novel noninvasive ablation technique which uses extremely high-amplitude focused ultrasound pulses to homogenize tumors and other unwanted soft tissue targets into an acellular slurry via acoustic cavitation. He earned an M.S. in Mechanical Engineering from Boston University where he was a Dean’s Fellow and a B.S. in Physics from the University of Washington. He worked professionally as a mechanical engineer for four years. Jon has authored nine journal publications and is listed as an inventor on seven issued patents.
John Propst serves as a Principal at Nexus NeuroTech Ventures, focusing on early-stage investments—including pre-seed and seed rounds—and overseeing the firm’s incubator program. Prior to Nexus, he served as Head of Operations for Health Platforms at Verily Life Sciences (Alphabet's healthcare company, formerly Google Life Sciences), where he led product and business operations across commercial device programs and directed large-scale national initiatives including Verily’s COVID-19 testing services, which served millions. Before Verily, John spent five years at Apple, where he helped lead the development and launch of Apple Watch from prototype through engineering, design, and production validation. He also supported New Product Introduction operations in the U.S. and Asia. He began his career as a biotech entrepreneur and later as the Associate Director of Business Development for the University of South Carolina Technology Commercialization Office.
John earned a Ph.D. in Biomedical Engineering and an M.B.A. from the University of South Carolina, where he was a Biomedical Science Scholar and W. Morgan Newton Award recipient. He holds a B.S. with Honors in Chemistry from Erskine College and has authored six journal publications.
