Janji is an independent athletic clothing company based in Boston. The company donates some of its proceeds to charities dedicated to improving access to clean water and advertises itself as being responsible and socially-conscious.2

How it started

History

Janji was founded by David Spandorfer and Michael Burnstein when they were students at Washington University in St. Louis. The original name of the business was "Edele." They changed the name, co-founder David Spandorfer said, because people could not figure out how to pronounce "Edele" and often confused the name with Adele. "Janji," its current and permanent name, means "promise" in Malay.

In 2010, Spandorfer and Burnstein won $15,000 in the Youthbridge Social Enterprise and Innovation Competition (SEIC) at Washington University; in 2011, they won an additional $20,000 from the UCCS Sports/Outdoors Business Plan Competition.

In May 2012, Janji launched their first product line at Big River Running, a specialty running store in St. Louis, Missouri. This first product line released shirts and shorts designed based on the flags of Haiti and Kenya.
