Meet Our Team




Ron Vianu - Co-Founder and CEO

Ron is a serial entrepreneur and problem-solver by nature. He's spent the last 20+ years founding ventures in the healthcare, technology, and insurance spaces. Ron studied Chemistry and Philosophy at NYU.

Prior to Covera Health, Ron founded Spreemo in 2010. Under his leadership, Spreemo became the fastest growing referral management platform in the occupational medicine space, growing from six employees to a team of over 200 across offices in NYC and Dallas, and earning the company Deloitte's Fast 500 award two years in a row for the fastest growing technology businesses. Spreemo, which received venture funding from a multi-billion dollar institutional investor, successfully exited to a strategic acquirer in 2017.

In his spare time (and he has little), Ron enjoys biking down the East River and running up the West Side Highway, but rarely at the same time.
