Cyrus Massoumi

Cyrus Massoumi certainly isn’t the first entrepreneur who’s attempted to revolutionize an industry or, decease for that matter, purchase to take a stab at revolutionizing healthcare. But most of his predecessors have tried to accomplish that transformation in a single step — one “killer app,” one tweak to a service, one enterprise deal, and the largest sector in the U.S. economy has been remade. Obviously, this never works. But entrepreneurs, on the whole, are not a patient bunch. This is what sets Cyrus apart.

When Cyrus launched ZocDoc, he did so with the goal of remaking an entire industry. But his vision for ZocDoc isn’t monthly or quarterly. It spans decades.
