Each year, Fast Company’s annual “Most Innovative Companies” issue recognizes the businesses putting an innovative stake in the ground in an effort to advance their respective fields and make a difference in the world.

This year, we are honored to share Doximity was ranked in the top five most innovative companies in the social category, alongside respected and acclaimed platforms working to disrupt their industries: Instagram, Pinterest, Snap, and Reddit.

In its short eight years since launching, the Doximity network has skyrocketed, exceeded the likes of the American Medical Association. Doximity's passion is helping clinicians by listening to their needs and creating simple tools to solve complex problems. [They] are working to create a future where medical communication is effortless and secure.

With the addition of nearly a quarter of a million members in 2017 alone, Doximity has the largest U.S. physician membership of any online network.

Most Innovative Companies is one of Fast Company's most significant and highly anticipated editorial efforts of the year. To produce the 2018 list, more than three dozen Fast Company editors, reporters and contributors identified the most notable innovations of the year from enterprises across the globe, and traced the impact of those initiatives on business, industry, and the larger culture.

Congrats to all the winners and special thanks to the Fast Company team!
