In April 2014, the company announced it had raised a $54 million financing round led by the venture capital firm Draper Fisher Jurvetson and the mutual fund company T. Rowe Price. Morgan Stanley Investment Management additionally invested. This investment brought Doximity's total funding to $81 million.

Doximity received $10.8 million in venture capital funding from Emergence Capital Partners and Interwest Partners​ in March 2011 and $17 million in Series B funding led by Morgenthaler Ventures in September 2012.

Residency Navigator

In 2014, Doximity launched Residency Navigator, a tool to help medical students find residency programmes that fit their professional needs. The Residency Navigator uses user-submitted evaluations and collected data to create a database of US residency programs, which students can then search and compare programmes through. [1]
