Ataraxia VC Research
Investment Thesis
Ataraxia Partners is an early-stage venture capital fund management company focused on helping people live longer and live better through science and technology. The firm explicitly positions itself at the intersection of health, happiness, and longevity—investing in breakthrough solutions that extend active lifespan and maximize human well-being. Ataraxia manages a diversified portfolio of specialized funds that share a common DNA: rigorous data-driven investment methodology and a belief that scientific innovation can drive both meaningful social impact and outsized financial returns.
The firm operates three distinct fund families, each with aligned but differentiated investment theses:
Joyance Partners invests in companies that deliver delightful moments to individuals through science and technology—spanning consumer health, food technology, beauty, wellness, and experiences that enhance daily life quality.
SH² (Science of Health and Happiness Fund) targets startups that help people live longer, live better, or both—with explicit focus on longevity, preventive health, therapeutic innovation, and quality-of-life improvements.
Social Starts (now in completion phase) built a legacy of 300+ early-stage investments since 2011, including 9 unicorns, using proprietary AI systems to identify exceptional founders in strong investment segments.
