Zack has been working at the intersection of health and technology for over 10 years. Believing that healthcare is the world's biggest solvable problem, Werner founded Labyrinth, a firm that works across private companies, policy, and social care to make preventative and whole person medicine the primary form of medicine practiced in the US. As a highly operational investor, Werner takes large positions in a small number of companies whose financial outcomes are aligned with the health outcomes of their customers, often taking board seats and working as a part time employee until these companies have reached escape velocity. 

Notable investments include Seed Health, Fullscript, and Function Health, where he sits on the board. Labyrinth also runs a think tank advising HHS on the use of AI in medicine. He plays lots of music, has three younger brothers, and loves great food.
