Immunity Project

Immunity Project was a San Francisco nonprofit and Y Combinator company (batch Winter 2014, one of YC's first non-profits alongside Watsi) that set out to develop a free HIV/AIDS vaccine. Its approach studied naturally immune "HIV controllers" and applied machine learning to reverse-engineer the immune response, aiming to deliver a crowdfunded, virus-free vaccine via nasal spray. Founders included Reid Rubsamen, Naveen Jain, and Ian Cinnamon. The organization surfaced in the API Evangelist network as a Y Combinator portfolio lead; enrichment found no developer portal, documentation, or API surface, and its former domain (immunityproject.org) has lapsed and now redirects to an unrelated third-party news outlet, indicating the project is effectively defunct.

Immunity Project is profiled on the APIs.io network. Tagged areas include Company, Nonprofit, Health Tech, Biotech, and HIV.
