About Us

Organizations that use healthcare data struggle with the challenge of extracting actionable insights and value from the massive and growing amount of data being generated.  The sheer volume of structured and unstructured data offers substantial opportunities to develop breakthrough clinical and commercial solutions yet the data is not “answer-ready”. After years of working with healthcare data, our team of data scientists, engineers, statisticians, medical advisors, and domain experts, dedicated ourselves to finding solutions to efficiently collect, organize, standardize, improve, analyze, and transform data to enable those serving patients to confidently and consistently achieve the best outcomes.

Origin of the Kythera Name

Our name is adopted from the ancient Greek Antikythera mechanism,  a 2,000-year-old mechanism described as the first analog computer - the oldest known example of such a device used to predict astronomical positions and eclipses. Despite its advanced age, its sophisticated technology bridges antiquity and modernity.

Leadership Team

The team at Kythera Labs has deep expertise in health care and has been solving problems for decades using proven data science concepts and unique technologies. Our team understands that trust is at the heart of innovation and it is something we work at every day.
