Hemant Virkar

President & CEO

With 30 years of experience as an executive and technical expert, Hemant Virkar is a visionary with a cause—helping organizations make the most of their data for the good of both business and public life. He got his start at the National Institutes of Health (NIH) addressing the business, operational, and transactional side of healthcare informatics. He also served ten years as president of a technology company where he restructured business operations to reduce operating costs 55%, achieve consistent 40% revenue growth rate, and increase the revenue base from $1 million to $30 million.

Yet, it was his experience on the patient side of healthcare—his father’s pancreatic cancer diagnosis—that ignited Mr. Virkar’s passion to meet healthcare’s great need for:

  • vital information in real time,
  • longitudinal data, and
  • basic information retrieval from disparate data sources.

Thus, he founded Digital Infuzion. Healthcare informatics remains a core corporate strength. Still, as business-minded innovator, Mr. Virkar quickly saw that pressing digital transformation and data needs exist across industries and that the talents, perspective, and approach his team had developed could help.

Mr. Virkar has built large-scale enterprise systems for a variety of customers, such as the NIH, Department of Defense, Department of Homeland Security, the World Bank, and the National Science Foundation.
