Nina Capital is a Barcelona-based healthtech VC founded by Stanford Biodesign's former Director of Digital Health that uses a systematic needs-first approach to identify healthcare problems before finding founders to solve them, focusing specifically on healthcare information technology rather than chasing trendy tech. The fund demonstrates unusually strong early-stage performance with over 80% of Fund I companies graduating from seed to next stage and Fund II portfolio revenue growing nearly 5x within two years, while maintaining deep regulatory expertise through a team that positions FDA compliance as a competitive advantage rather than a burden.
