About the company

Adia makes clinicians better diagnosticians.

Adia is set to revolutionize the diagnostic process for both doctors and patients. Leveraging our extensive knowledge and experience in medicine, coupled with advanced technology and AI, we aim to improve diagnostic accuracy while also reducing and optimizing costs. This leads to more satisfied patients, efficient doctors, and less financial burden for all involved. 

Adia enables advanced clinical decision support (CDS) and guides lab test selection and result interpretation by using patient’s data and clinical context. On top of that Adia changes how healthcare providers get paid by combining predictive and guiding diagnostic decisions with medical claim factoring that advances payments to providers. The whole medical journey is getting automated. 

By effectively "underwriting" medical services to confirm payment eligibility from health plans, Adia ensures real-time payments to providers. This frees providers from the uncertainties of payer reimbursements, enabling predictable cash flow for better business management and patient care. 

Adia commits to building products with the latest technology, finest predictive models, LLMs, a comprehensive medical Knowledge Graph, and more.
