What Previty Is
Previty is a physician-led clinical intelligence company operating at the intersection of preventive medicine, population health, and artificial intelligence. We advise AI and health technology companies on clinical strategy, connect physician experts to organizations building the future of healthcare, and develop clinical algorithms and risk models built for licensing and deployment.
Our work is grounded in the Previty Method™ — a physician-designed framework that defines how clinical expertise enters the AI development process, responsibly and at scale. Previty connects vetted physician experts to the health technology companies that need them, and builds the clinical algorithms and tools that health systems and health plans can deploy with confidence.
A Clinical Intelligence Company
Built for the AI Era.
Clinical Foundation
The Expertise
Behind the Platform.
Previty is founded and led by a triple board-certified physician and healthcare executive, Dr. Tanya Phares, with over 25 years of experience spanning managed care, public health, and health system leadership. Clinical credentials include board certification in Internal Medicine, Public Health & Preventive Medicine, and Lifestyle Medicine, with executive training as a Certified Physician Executive (CPE).
Experienced in leading healthcare organizations, she has served as a founding Chief Medical Officer for a health plan, led NCQA accreditation efforts, conducted research for the CDC, developed national preventive health guidelines, and managed population health programs at county scale. This depth of systems-level, executive, and clinical experience is what makes Previty's advisory work and algorithm development substantively different from technology-first approaches.
— Why I Built This
I spent more than two decades inside the systems that clinical AI is now trying to transform — leading health systems, developing population health programs and conducting public health research, influencing health policy at the state and national level. I have been in the rooms where these decisions get made.
What I kept seeing was the same pattern: health technology companies building consequential clinical tools without a physician in the room who understood both the science and the system. The result was tools that were technically impressive and clinically incomplete.
Previty exists to change that. Not by adding a physician as a figurehead — but by building a community of physicians who are trained, principled, and present at every stage where clinical judgment matters. The Previty Method™ is the standard we hold ourselves to. The network is how we make it real at scale.
If you are a physician who wants to be part of that — this is your community.
