Viridus is a Massachusetts-based online professional network startup. It was originally founded in 2007 in Arlington, Massachusetts by Furqan Nazeeri, Entrepreneur-in-Residence at Softbank Capital and Michael DiPietro, a former VP at an environmental, health and safety software company.
In April 2008, the company announced the beginning of a private beta.
Viridus is a mashup of the Latin root virid meaning "green" and us or community. It is pronounced veer-id-us.
